However, scientists can theorize how ammonites survived for millions of years based on the life and nature of its surviving relatives and other inferences they can make from found fossils.Īmmonites were carnivores that fed on plankton. Not much can be confirmed about its way of life as ammonites and its closest relatives did not survive the extinction. Based on fossils, their sizes varied, from small ammonites that were around an inch long, to shells that were many feet long. Ammonites bred frequently and lived in schools, which is why there were abundant fossils clumped in groups. They first appeared around 240 million years ago, during the Devonian period during the Paleozoic era. However, unlike squid or octopuses, ammonites had a hard shell that protected their body which was soft and filled with tissue and vital organs.Īmmonites originated from cephalopods called bacrites. These were mollusks that resembled squid or octopuses and are a close relative of these animals we have today. The term “ammonite” comes from the Egyptian god Ammon (Amun), who supposedly wore ram horns. In this article, we discuss everything you need to know about ammonite fossils if you’re curious to learn more about it and its purpose in marine life before extinction.Īmmonite fossils come from ammonites or ammonoids, a type of Ammonoidea, which is a subset of Cephlopoda or cephalopods. With its unique formation and interesting history, casual fossil collectors may want to have an ammonite fossil in their collection. There were even bigger than the average human person. In some photos, these fossils had a diameter of two or three inches, while in other photos, there were some that were bigger than an average head. One type of fossil that caught my attention while browsing through websites was the ammonite fossil. I even found legitimate fossil sellers on EBay and Amazon. I found websites such as FossilEra, Fossil Shack, Paleo Direct, and The Fossil Store. It’s common to see fossils in museum, but did you know that you can actually by fossils online? There are some legitimate online stores that sell authentic fossils ranging from dinosaur bones to insect specimens trapped in amber.
