Dinosaurs with dome-shaped bumps on their heads are Pachycephalosaurs. It’s a group of dinosaurs that had species such as Pachycephalosaurus and Stegoceras.
What kind of dinosaur has a hard head?
The dinosaurs known for their hard head were a type of dinosaur known scientifically as Pachycephalosaurs (also known as the thick headed lizard). This bony dome dinosaur is globally recognized for its signature thick-boned skulls. They roamed North America during the Late Cretaceous period (145 to 66 million years ago).
What do dinosaurs with head crests look like?
Dinosaurs with head crests are one of the most interesting and diverse-looking prehistoric creatures. None look exactly alike though they all share the common feature of a head crest.
What are the characteristics of a dinosaur skull?
● The skull on the dome or bump was so thick that it often was the only part of the dinosaur that survived. ● The thickness of the bump was different depending on the species. In the Pachycephelosaurus wyomingensis, the skull was 9 inches (22.8cm) thick.

What dinosaur has a ridge on its head?
Dilophosaurus was a fast-moving meat-eating dinosaur. A kink in its upper jaw may mean that it ate a certain kind of food, or attacked by gripping and holding on to prey – modern crocodiles have a similar kink. The pair of thin bony crests on its head may have been for display.
What dinosaur has a bone head?
PachycephalosaurusPachycephalosaurus is the largest known dome-skulled, or bone-headed, dinosaur. These dinosaurs had extremely thick skulls, and they formed the group known as the pachycephalosaurs.
What is the bump on Brachiosaurus head?
As a general rule, scientists agree the bump on the head of the Brachiosaurus served as nostrils for the dinosaur. The nostrils are similar to other sauropods and dinosaurs in general.
Why do dinosaurs have bumps?
Most large theropods -- in fact 20 of the largest 22 species like T. rex and Allosaurus -- have bony bumps or crests on their heads. Paleontologists hypothesize that the accoutrements served as socio-sexual display mechanisms -- a way for the dinosaurs to signal to one another for mating, territory or defense purposes.
How do you identify a dinosaur?
Dinosaur identification requires knowledge of the main dinosaur groups and their distinguishing features. Accurate identification requires knowledge of various dinosaur features, such as size, body structure, horns, spikes, armor, teeth, claws, clubs, sails, feathers and frills.
Which dinosaur had the thickest skull?
Pachycephalosaurus wyomingensisPachycephalosaurus wyomingensis was the largest of the pachycephalosaurids—"thick-headed dinosaurs"—which featured extremely thick skullcaps. The top of a Pachycephalosaurus skull could be 9 inches (23 centimeters) thick, and much of the skull and the snout were also covered by small bony knobs and spikes.
Why is it no longer called a Brontosaurus?
When scientists looked at these fossils later they realized that the Apatosaurus was the same animal as the Brontosaurus. Scientists use the first name given to an animal, so they decided to rename the Brontosaurus to Apatosaurus because Apatosaurus came first.
What was the biggest dinosaur?

Whats the difference between a Brontosaurus and a Brachiosaurus?
Brontosaurus vs Brachiosaurus: What's the difference Brontosaurus and Brachiosaurus are separate species and, yes, it is possible to tell them apart. The main difference between them is their size. Brachiosaurus is much larger and heavier than the smaller Brontosaurus, although they were both incredibly big dinosaurs.
What dinosaur has a bump on its nose?
Ceratosaurus means "horned lizard" because it has a sort of rounded bump on its nose. With its powerful paws and its great head, the ceratosaurus is one of the most ferocious of all dinosaurs!
Did flying dinosaurs exist?
Pterosaurs (/ˈtɛrəsɔːr, ˈtɛroʊ-/; from Greek pteron and sauros, meaning "wing lizard") is an extinct clade of flying reptiles in the order, Pterosauria. They existed during most of the Mesozoic: from the Late Triassic to the end of the Cretaceous (228 to 66 million years ago).

10 Dinosaurs With Head Crests That Are Fun To Learn About
This fun resource we made about dinosaurs with head crests will show different kinds of species that sported the look and help answer why they had crests too.
Pachycephalosaurus | Jurassic Park Wiki | Fandom
"Friar Tuck" It was not planned for InGen's Jurassic Park on Isla Nublar.. Wild on Isla Sorna. When Hurricane Clarissa hit Isla Sorna, the InGen workers evacuated the island. The Pachycephalosaurus were either freed by the fleeing workers or broke free themselves. From this point on, the Pachycephalosaurus and many of InGen's dinosaurs integrated themselves into Isla Sorna's ecosystem.
Pachycephalosaurus Discovery
The first Pachycephalosaurus fossil was found by Donald Baird in 1859. An early fossil collector in the Western North America he collected a bone fragment in the vicinity of the head of the Missouri River. This is what is now known to be the Lance Formation in southeastern Montana.
Pachycephalosaurus Measurements
Pachycephalosaurus grew to be about 16 feet (5 meters) long, they were bipedal with strong hind limbs and very short forelimbs. The height of the Pachycepholosaurs could reach between 5ft-7ft tall. This is based on the reconstruction of fossils from Montana, South Dakota, and Western U.S.
Pachycephalosaurus Skull
Why did Pachycephalosaurus have such a thick skull? Some scientists think the purpose of having such a thick skull may have protected their tiny brain while head butting other dinosaurs for defense against predators, while many other scientists say their dome heads also helped attract mates.
Pachycephalosaurus Diet?
The Pachycephalosaurus diet is believed to be mostly plant-based being herbivores that lived during the Late Cretaceous period. However, scientists believe they might have actually eaten both plants and meat (omnivorous) due to the shape of their teeth.
Pachycephalosaurus Behavior
Pachycepholosaurs were also known to be one of the most aggressive and territorial dinosaurs. When two Pachycephalosaurus met, they would lower their heads and charge at each other. The dinosaur with the harder head would usually win the battle.
Stygimoloch
Stygimoloch is from the genus pachycephalosaurus family. It was distinguished from other pachycephalosaurs by the row of spikes on the back of its head, behind the dome characteristic of the family. The meaning of the name Stygimoloch means a demon from the river Styx (yes, that river of styx of greek mythology).
What is the name of the dinosaur with a bump on its head?
As a general rule, scientists agree the bump on the head of the Brachiosaurus served as nostrils for the dinosaur. The nostrils are similar to other sauropods and dinosaurs in general. According to new research, the position of the nostrils, forming a bump on the dinosaur’s head, should likely be positioned closer to the front of the nose.
What animal has an egg-shaped head and nostrils?
This species had an egg-shaped head and nostrils at the top. The size of its nasal openings in the skull indicates that Brachiosaurus had an elaborate sense of smell.
What Special Features Did The Brachiosaurus Have?
Brachiosaurus was a highly unusual dinosaur. It lived 150-156 million years ago and resembled gigantic giraffes.
Why do Brachiosaurus have snouts?
The land animal also breathed via its huge nostrils to sustain its high-rate metabolism. Nostrils tell how a creature smelled and breathed.
Why did Brachiosaurus have a high stance?
For instance, they know that Brachiosaurus had an unusually high stance, possibly because it needed to reach up into trees to feed itself. He also used his long neck for defense against predators who dared hunt him! But without a living specimen, we only have fossils to help determine more about how this dinosaur lived and the exact type of anatomy it had.
How high can a Brachiosaurus be?
It could tower up to 26 meters (50 feet) high and make an imposing defensive stance. Its tail was short and thick, which improved its balance. The tail was almost useless for defense reasons. But, it prevented Brachiosaurus front constant falls. A fall could easily shutter the egg-shaped head of the dinosaur.
How high can a dinosaur stand?
The longer forelimbs also gave this dinosaur species an exceptionally high stance. It could tower up to 26 meters (50 feet) high and make an imposing defensive stance.
What is the name of the dinosaur with no nose horn?
When its type fossil was first discovered, in Utah in 1923, Arrhinoceratops seemed to be missing the small nose horn possessed by most ceratopsians; hence its name, Greek for "no-nose horned face." Wouldn't you know it, Arrhinoceratops had a horn after all, making it a very close cousin of Triceratops and Torosaurus (which may have been the same dinosaur). This small mixup aside, Arrhinoceratops was very much like other ceratopsians of the late Cretaceous period, a four-footed, elephant-sized herbivore that likely used its long horns to battle other males for the right to mate.
What dinosaur is horned?
At first glance, this ceratopsian (horned, frilled dinosaur) looks indistinguishable from its better-known cousin Triceratops, until you notice the small, triangular projections on the top of Anchiceratops' massive frill (which, like most such anatomical features, were probably a sexually selected characteristic).
Why are wendiceratops so important?
Announced to the world in 2015, the horned, frilled dinosaur Wendiceratops is important for three reasons. First, it's the earliest identified ceratopsian dinosaur to sport a horn on its nose; second, it's one of the earliest identified members of the family of ceratopsians that eventually gave rise to Triceratops about 10 million years later; and third, the elaborate ornamentation of its head and frill show that these striking anatomical features evolved millions of years before paleontologists had previously thought. Wendiceratops is also one of the handful of dinosaurs to be named after a female, in this case noted Canadian fossil hunter Wendy Sloboda, who discovered its bonebed in Alberta in 2010.
What dinosaurs were in the Cretaceous?
Most of the ceratopsians ("horned faces") of the late Cretaceous period were gigantic, multi-ton earth-shakers like Triceratops, but millions of years earlier, in the eastern regions of Asia, these dinosaurs were much more petite. One such smaller dinosaur was Bagaceratops, which only measured about three feet long from snout to tail and weighed just 50 pounds. This fairly obscure, minimally ornamented ceratopsian ancestor is known mostly by the partial remains of various skulls; a complete skeleton has yet to be unearthed, but it's clear that Bagaceratops closely resembled the other primitive ceratopsians of the middle-to-late Cretaceous.
Why are there more ceratopsians than any other dinosaur?
Over the past decade, more ceratopsians (horned, frilled dinosaurs) have been identified than any other type of dinosaur, probably because these plant-eaters' massive skulls tend to persist well in the fossil record.
Where was Diabloceratops found?
Although Diabloceratops has only recently been announced to the general public, this horned dinosaur has been familiar to paleontologists ever since 2002, when its near-intact skull was discovered in southern Utah. Eight years of analysis and preparation have yielded what may (or may not) be a ceratopsian "missing link": Diabloceratops seems to have evolved from the smaller horned dinosaurs of the early Cretaceous period, yet it predated more advanced genera like Centrosaurus and Triceratops by millions of years. As you might expect given its evolutionary position, the massive head of Diabloceratops was ornamented in a unique way: it lacked a horn on its snout, but had a medium-sized, Centrosaurus-like frill with two sharp horns jutting up from either side. (It's possible that Diabloceratops' frill was covered with a thin layer of skin that changed color during mating season.)
When did ceratopsians first appear?
Tiny, cat-sized members of the breed (like Psittacosaurus) originated over 100 million years ago in Asia, during the early to middle Cretaceous period, and grew to Triceratops -like sizes by the time they reached North America in the late Cretaceous. What makes Aquilops important is that it's the first small, "Asian" ceratopsian ever to be discovered in North America, and thus represents an important link between the eastern and western branches of this populous dinosaur family. (By the way, for over a decade the type fossil of Aquilops was identified as Zephyrosaurus, a non-ceratopsian ornithopod, until a re-examination of the remains prompted this new assessment.)
What is the name of the dinosaur with a crest?
It’s the Parasaurolophus’ one of a kind crest that made it distinct from other well-known dinosaurs. It had a large and intricate cranial tube on its head that curved backwards forming a crest-like shape.
What dinosaurs have long feathers?
Here’s another dinosaur to add your list of feathered prehistoric creatures. The Oviraptor had long feathers on its arms and tail. The tail had a pygostyle structure which supported the feathers that fanned from it.
What dinosaur looks like a cross between a cassowary and a Greek soldier’s helmet?
What dinosaur looks like a cross between a cassowary and a Greek soldier’s helmet? A lot of other dinosaurs with crests may come to mind but the Corythosaurus is the best answer.
What was the largest dinosaur in the Triassic period?
The largest and most represented Triassic dinosaurs from Europe were also fast and carnivorous theropods. Liliensternus devoured prey by first outrunning them with their swift legs. Then they disabled the dinosaurs like the Plateosaurus with their sharp-edged teeth.
Why do dinosaurs use crests?
Paleontologists suggest that they were used for intra-species recognition. It means these dinosaurs used them to identify or distinguish members of the same species. They go on to share that the crests were probably used during seasons of mating.
How much does a Corythosaurus weigh?
Did you know the Corythosaurus is one of the heaviest and biggest duck-billed dinosaurs there are? It’s estimated to weigh as heavy as 7,640 lbs and as long as 27 feet!
Why is the Dilophosaurus' head cooler?
The Dilophosaurus makes dino head accessories even cooler as it’s a dinosaur with a double head crest. Scientists suggest that it may have used its crest to regulate body heat or identify other members of its species.
What is the name of the dinosaur with a bent jaw?
You can glean everything you need to know about Angulomastacator from its clunky name, Greek for "bent chewer." This late Cretaceous hadrosaur (duck-billed dinosaur) resembled others of its kind in most ways, with the exception of its oddly angled upper jaw, the purpose of which remains a mystery (even the paleontologists who discovered this dinosaur describe it as "enigmatic") but probably had something to do with its accustomed diet. Its strange skull aside, Angulomastacator is classified as a "lambeosaurine" hadrosaur, meaning it was closely related to the much better known Lambeosaurus.
What dinosaurs were found in the woods?
Among the earliest of all the hadrosaurs, or duck-billed dinosaurs--roaming the woodlands of Asia at least 10 million years before more famous descendants like Charonosaurus--Bactrosaurus is important because it possessed certain characteristics (such as a thick, squat body) more often seen in iguanodont dinosaurs.
How big is a Huaxiaosaurus?
A non-sauropod dinosaur, technically, a hadrosaur, that measured 60 feet from head to tail and weighed as much as 20 tons: surely, you think, Huaxiaosaurus must have caused a huge splash when it was announced in 2011. And so it would have, if most paleontologists weren't convinced that the "type fossil" of Huaxiaosaurus actually belongs to an unusually large specimen of Shantungosaurus, already acclaimed as the largest duck-billed dinosaur ever to walk the earth. The main diagnostic difference between Huaxiaosaurus and Shantungosaurus is a groove on the underside of its lower vertebrae, which can just as easily be explained by advanced age (and a superannuated Shantungosaurus may well have weighed more than younger members of the herd).
Where was the Amurosaurus found?
Amurosaurus may be the best-attested dinosaur ever to be discovered within the confines of Russia, although its fossils were unearthed on the far fringes of this vast country, near its eastern border with China. There, an Amurosaurus bonebed (which was probably deposited by a sizable herd that met its end in a flash flood) has allowed paleontologists to painstakingly piece together this large, late Cretaceous hadrosaur from various individuals. As far as experts can tell, Amurosaurus was very similar to the North American Lambeosaurus, hence its classification as a "lambeosaurine" hadrosaur.
How long does it take for a hypacrosaurus to reach adulthood?
Paleontologists have discovered the well-preserved nesting grounds of Hypacrosaurus, complete with fossilized eggs and hatchlings; we now know that these hatchlings attained adulthood after 10 or 12 years, faster than the 20 or 30 years of some meat-eating dinosaurs.
How many fossils have been found of Brachylophosaurus?
Paleontologists have unearthed three complete fossils of Brachylophosaurus, and they're so amazingly well-preserved that they've been given nicknames: Elvis, Leonardo, and Roberta. (A fourth, incomplete specimen is known as "Peanut.") Se our in-depth profile of Brachylophosaurus for more information about them.
Where is the Claosaurus sinking?
Claosaurus sinking to the bottom of the Western Interior Sea.
What is the name of the dinosaur that lived in North America?
Pachycephalosaurus gives its name to the Pachycephalosauria, a clade of herbivorous ornithischian ("bird hipped") dinosaurs which lived during the Late Cretaceous Period in North America and Asia. Despite their bipedal stance, they were likely more closely related to the ceratopsians than the ornithopods.
What is the largest known pachycephalosaur?
Pachycephalosaurus is the largest-known pachycephalosaur. The thick skull domes of Pachycephalosaurus and related genera gave rise to the hypothesis that pachycephalosaurs used their skulls in intra-species combat. This hypothesis has been disputed in recent years.
What did dinosaurs eat?
It is assumed that pachycephalosaurs lived on a mixed diet of leaves, seeds, and fruits. The sharp, serrated teeth would have been very effective for shredding plants. It is also suspected that the dinosaur may have included meat in its diet. The most complete fossil jaw shows that it had serrated blade-like front teeth, reminiscent of those of carnivorous theropods.
What would happen if the Pachycephalosaurus was intimidated?
If intimidation failed, the Pachycephalosaurus would bend its head downward and to the side, striking the rival pachycephalosaur on its flank.
What is the difference between a pachycephalosaurus and a pachycephalosaurus?
The skull was short, and possessed large, rounded eye sockets that faced forward, suggesting that the animal had good eyesight and was capable of binocular vision. Pachycephalosaurus had a small muzzle which ended in a pointed beak. The teeth were tiny, with leaf-shaped crowns.
What is the family of pachycephalosaurids?
Accordingly, what are now known as pachycephalosaurids were assigned to the family Troodontidae, a misconception not corrected until 1945, by Charles M. Sternberg. In 1943, Barnum Brown and Erich Maren Schlaikjer, with newer, more complete material, established the genus Pachycephalosaurus.
How big is a pachycephalosaurus?
It has been estimated that Pachycephalosaurus was about 4.5 metres (14.8 ft) long and weighed about 450 kilograms (990 lb). Based on other pachycephalosaurids, it probably had a fairly short, thick neck, short fore limbs, a bulky body, long hind legs and a heavy tail, which was likely held rigid by ossified tendons.
What is the name of the creature with a large bump on its head?
Pachycephalosaurs are most noted for the large bump on their head, but as they were different species, there were also different skull shapes. A few species had small bumps and cone-shaped spikes, but the head was flat, while others just had a large dome bump on its head.
What are the hard headed dinosaurs?
The Hard-Headed Dinos . Imagine you are hunting fossils, and you find a fossil skull, some rib bones, and thigh bones. As you chip away the dirt and rock from the skull, to your amazement, you find that it has a well-defined bump on the top of it as well as cone-shaped spikes and knobs surrounding it, almost in the shape of a crown.
How Thick is a Pachycephalosaurus Skull? How Tall is a Pachycephalosaurus?
Pachycephalosaurs are most noted for the large bump on their head, but as they were different species, there were also different skull shapes. A few species had small bumps and cone-shaped spikes, but the head was flat, while others just had a large dome bump on its head. The anatomy of these dome-headed dinosaurs was also a little bit different depending on the species.
How many types of pachycephalosaurs are there?
Classification of Pachycephalosauria and Habitat. Paleontologists have classified more than 15 types of Pachycephalosaurs, which has given much insight into how these dinosaurs lived and survived in different habitats. The Dracorex is a real dinosaur and lived in what is now South Dakota in the US.
How big is the largest fossil of a pachycephalosaur?
It is the biggest fossil specimen of Pachycephalosaurs. Estimated to be 14.8 feet (4.5 m), it has the recognizable dome-shaped skull with cone-shaped spikes and bumps on its snout and along the outer edges of its dome.
Why do fossil skulls fossilize?
Fossil skulls tend to fossilize well because the bone is considerably thicker than some smaller bones. When it comes to Pachycephalosaurs: ● The skull on the dome or bump was so thick that it often was the only part of the dinosaur that survived. ● The thickness of the bump was different depending on the species.
Where was the Stegoceras found?
Stegoceras was a dome-headed dinosaur that roamed in North America. It’s fossils were found in Alberta, Canada. The skull did not have spikes or bumps and it was a smaller species compared to Pachycephelosaurus that was found in Wyoming.
