An orthoceras is an ancient mollusk that lived in the Ordovician period. At that time, the earth was mostly covered in water. It had a soft squid-like body inside a cone shell. Over time, its aragonite shell turned into calcite and fossilized. Let's explore more fun facts about this fascinating marine fossil!Oct 30, 2019

What is Orthoceras?

Orthoceras was an ancient mollusk that lived more than 400 million years ago. The name means straight horn, referring to the characteristic long, straight, conical shell. The preserved shell is all that remains of this ancestor of our modern-day squid. The soft body lived in the last open-ended segment at the large end of the conical shell.

Did Orthoceras grow feet out of its head?

Ancient Mollusk Grew Feet Out of its Head! Orthoceras was an ancient cephalopod that lived about 370 million years ago. The name means straight horn, referring to the characteristic long, straight, conical shell. The preserved shell is all that remains of this ancestor of our modern-day squid. There is some confusion around the name.

Where can you find Orthoceras fossils?

Orthoceras fossils are found all over the world. These popular fossils are found in Sweden, Morocco, and even in Antarctica. When archaeologists find orthoceras fossils, they are abundant. There are often thousands of them in the same digging site! These fossils have beautiful contrast, especially when they’re polished. 6.

When did the Orthoceras go extinct?

Related to today's squid and octopus, the orthoceras was one of the first of this group of cephalopods. They thrived in shallow seas all over the world during the Paleozoic Era and into the Triassic Period before finally going extinct.

Are orthoceras fossils real?

The fossils commonly known as orthoceras are extinct "straight-shelled" cephalopods that lived during the Upper Devonian period around 370 million years ago. They lived inside of their shell, had tentacles they could use to grab food and used jet propulsion, squirting water to move.

How old is a orthoceras fossil?

Found in the Atlas Mountains of Morocco, Orthoceras are an extinct Nautiloid cephalopod that lived from the Ordovician Period to the Triassic Period (500 – 200 million years ago).

Why did orthoceras go extinct?

The Orthoceras lived for a long time, up to 200 million years. However, its population began to decline in the Permian period, due to competition from other groups of cephalopods. The Orthoceras is now extinct, but its fossils are common and can be found all over the world.

What did orthoceras look like?

Orthoceras (which translates as “straight horn”) Nautiloids had long, cone shaped shells, and must have swum like torpedoes through ancient seas. These distinctive black and white specimens come from Morocco, and are often quarried in slabs teeming with fossil Orthoceras shells.

Is Orthoceras fossil rare?

When archaeologists find orthoceras fossils, they are abundant. There are often thousands of them in the same digging site! These fossils have beautiful contrast, especially when they're polished.

Why are Orthoceras fossils polished?

Like other cephalopods they lived inside of their shell, had tentacles they could use to grab food and used jet propulsion, squirting water to move. The rock containing them is quarried from the Atlas Mountains of Morocco and frequently polished to make decorative items with the fossils visible on the polished surface.

Is Orthoceras a dinosaur?

Orthoceras fossils are the remains of an invertebrate, an animal that has no backbone, that belongs to the Phylum Mollusca.

Are ammonite fossils worth money?

Well, the largest ammonites with special characters can fetch a very high value above $1,000. Most of them are below $100 though and the commonest ammonites are very affordable. Some examples : an ammonite Acanthohoplites Nodosohoplites fossil from Russia will be found around $150.

Do ammonites still exist?

The ammonites became extinct at the end of the Cretaceous, at roughly the same time as the dinosaurs disappeared. However, we know a lot about them because they are commonly found as fossils formed when the remains or traces of the animal became buried by sediments that later solidified into rock.

What did Orthoceras eat?

Orthoceras are hunters since they have a flexible diet. Whether it's trilobites or plankton, they ate it all. A trilobite is a sea creature that's closely related to today's horseshoe crab. They're one of the first creatures to develop eyes.

Orthoceras and related orthoconic nautiloid cephalopods are often confused with the superficially similar Baculites and related Cretaceous orthoconic ammonoids. Both are long and tubular in form, and both are common items for sale in rock shops (often under each other's names). Both lineages evidently evolved the tubular form independently of one another, and at different times in earth history. Orthoceras lived much earlier (Middle Ordovician) than Baculites (Late Cretaceous). …
