Are dinosaur bones really millions of years old?
The recent discovery of radiocarbon in dinosaur bones at first seems incompatible with an age of millions of years, due to the short half-life of radiocarbon. However, evidence from isotopes other than radiocarbon shows that dinosaur fossils are indeed millions of years old.
Can you keep a dinosaur bone if you find it?
In the United States, the fossilized remains of the mighty creatures that lived in eons past are subject to an age-old law—”finders keepers.” In America, if you find a dinosaur in your backyard, that is now your dinosaur.
Do fossils deteriorate?
To maintain its integrity, sub-fossil bone needs to be kept in a stable environment. Once it is removed from the matrix in which it is found, it is likely to deteriorate rapidly, especially, if it is wet, and the bone is subjected to extreme fluctuations of temperature and humidity.
How old are dinosaur bones?
Park fossils document dinosaurs from the Late Triassic (approximately 210 million years ago) to the end of the Cretaceous (66 million years ago).
How much is a dinosaur bone worth?
A complete dinosaur skeleton can cost millions, even many millions! A real dinosaur tooth can run anywhere from $20 to a few thousand dollars depending on the quality of the tooth and how rare it is to find a particular species. Bone fragments, coprolite, and eggshell pieces can be very reasonably priced.
Do dinosaur bones still have DNA?
According to a news release from the Chinese Academy of Sciences, the femur cells contained preserved nuclei and chromatin fragments that could potentially hold preserved dinosaur DNA. The scientists discovered this by staining the extracted cells with hematoxylin, a chemical that binds to cell nuclei.
Do fossils take 100 years to form?
Answer: Fossils are defined as the remains or traces of organisms that died more than 10,000 years ago, therefore, by definition the minimum time it takes to make a fossil is 10,000 years.
Why didn't the dinosaur bones decompose?
Its bones are protected from rotting by layers of sediment. As its body decomposes all the fleshy parts wear away and only the hard parts, like bones, teeth, and horns, are left behind. Over millions of years, water in the nearby rocks surrounds these hard parts, and minerals in the water replace them, bit by bit.
Can fossils come back to life?
The answer is no. Dinosaur eggs are tens to hundreds of millions of years past their Use By date, and fossilized to boot -- not exactly prime incubator material. As for the embryos, they are just so many piles of bone. Not much help there.
What does the Bible say about dinosaurs?
According to the Bible, dinosaurs must have been created by God on the sixth day of creation. Genesis 1:24 says, “And God said, Let the earth bring forth the living creature after his kind, cattle, and creeping thing, and beast of the earth after his kind: and it was so.”
Can dinosaur DNA be recovered?
Dig up a fossil today, and any dino-DNA within would have long since fallen apart. That means, as far as scientists know, and even using the best technology available today, it's not possible to make a dinosaur from its DNA.
How old could T. rex get?
Probably not more than about 28 years. Growth rings indicate the T. rex grew quickly, reaching adult size as a teenager—and that the animals died young. The oldest specimen analyzed was only 28 years old.
What do I do if I find dinosaur bones?
The most important thing to do if you find what you believe is a fossil or an artifact is to leave it where you found it. When scientists study these items, we need to know exactly where they came from so that we can learn everything possible about them.
Can you keep a fossil you find in your backyard?
The US federal land laws forbid any collection of vertebrate fossils without an institutional permit, but allow hobby collection of common invertebrate and plant fossils on most federal land , and even commercial collection of petrified wood.
Can I keep a fossils you find?
Collected fossils remain public property and are placed with museums, universities or other public institutions for study and exhibition. You may collect reasonable quantities of common invertebrate fossils such as mollusks and trilobites, but this must be for personal use, and the fossils may not be bartered or sold.
What to do if you find a fossilized bone?
As strong as the urge to dig might be, Natural History Museum of Utah collections manager Carolyn Levitt-Bussian says, the best thing to do is leave the fossil where it is. It doesn't matter whether it's a shell, trilobite, dinosaur track, or ancient bone.
How long have humans been able to reconstruct dinosaur bones?
It just so happens that those beings who found the bones had the ability to recognize them. And even more unlikely, it’s only been the last 200 years that humans have been able to reconstruct the likely form those dinosaurs had from the bones. It is truly astonishing that we know as much about dinosaurs as we do.
What is the process of replacing bones with minerals?
Fossilization is a process where bones (or some other materials, like shells or wood, etc) are replaced by minerals in such as way that the shape is maintained; or where the pits and bumps left behind by, say, skin or feathers or footprints are filled in by minerals, again mimicking the original shape. Wikipedia describes some of the ways in which fossils can form: Fossil
How many fossils are there in the fossil cabin?
Fossil Cabin was built out of 26000 dinosaur fossils, all found nearby. At seashores, you can walk over mile after mile of fossils (often mostly small sea creatures, but that's what most animals in the past were).
How many fossils are there in the La Brea Tar Pit?
Fossils of large animals are relatively rare, but still are much more common than most people realize. The La Brea tar pit museum alone has over 3 million fossils; here's one of the many rows of drawers containing them:
Do dinosaur bones turn into rocks?
Because, to put it simply, after millions upon millions of years, the dinosaur bones turn into rock-making them fossils, or rock, rather than actual bones in most cases. However, there are instances where the dinosaur bone is no completely stone… making it a bone of a dinosaur, or at least partly. New dinosaur discoveries are made every day, and you really have to think of dinosaurs as animals and not pop culture characters to fully understand their world.
Do dinosaur bones have fossils?
For the most part they are. Only a tiny fraction of all the dinosaurs that ever lived left behind fossils. Those bones we have are mineralized remains, where the organic parts have been replaced by minerals. Those bones happened to have been buried by sediment before they rotted away.
Did dinosaurs evolve?
Yes - of course they evolved. That’s how there got to be dinosaurs in the first place!
What happens when a dinosaur bone is encased in sedimentary rock?
When a dinosaur bone is encased in sedimentary rock, the moisture from the surrounding sediment infuses the bone with these minerals. This, essentially, turns the bone to stone.
How long have dinosaur bones been around?
by Michael Haralson. in adventuredinosaurs.com. Dinosaurs roamed the earth over 65 million years ago, but somehow their remains are here for us to study. Not every creature’s bones become fossilized, so why do some dinosaur bones last so long and others don’t? It’s amazing to think they have lasted so long, some skeletons are even more ...
What does it mean when a dinosaur bones are fossilized?
Dinosaur bones truly fossilize, which means that they are encased in sedimentary rock.
How long do bones last?
Our bones aren’t soft like the rest of our bodies, so they are less susceptible to deterioration and rot. But if every bone or tooth lasted forever, they could be found in every inch of the earth. Some bones last millions of years while others can deteriorate in less than a decade. To understand why some bones can last millions of years, ...
Where does sediment move?
The sediment that is moved by water usually ends up under bodies of water, while sediment moved by wind can be found in places like badlands. When a dinosaur bone is encased in sedimentary rock, the moisture from the surrounding sediment infuses the bone with these minerals. This, essentially, turns the bone to stone.
What happens to fossils when they are excavated?
If these fossils are excavated before they wear down, they have no chance of further erosion and will last basically forever. Even if they are in a warm or damp environment, they are no longer made of collagen and calcium phosphate, so there is nothing for bacteria to feed on. They are simply mineral.
Why is erosion unlikely?
Erosion can happen but is very unlikely due to their incasing in the sedimentary rock. This rock is usually left basically untouched under the surface of the earth, as they can only fossilized in areas of little vegetation, thus very little life in the surrounding ecosystem.

- Lastly,I think it’s important to discuss why dinosaur bones are the bones most foundas fossils. While there are many different kinds of fossils that have norelationship to dinosaurs as a species, we do have to recognize that manyfossils are indeed dinosaurremains. This probably just has to do with the erasin which they existed. Atthat time, there w...
