It's an Orthocone, a distant relative of squid and cuttlefish, but they're as long as a truck! That is th biggest predator that the world has seen up until this time.
— Allen, on Cameroceras

Cameroceras ("Chambered Horn"), also called the Giant Orthocone, was a large orthocone from the Ordovician. It was not only the largest predator, but the largest animal to have ever existed during that time. They wre also the largest known giant orthocones and were ansectors of modern-day squid.



Cameroceras lived during the Ordovician and the Silurian, between 470 to 408 million years ago, living alongside a variety of other sea creatures, including trilobites, sea scorpions, fish, and even other Cameroceras. It was the top predator of its time.


Cameroceras was the largest predator of its time, measuring over 30 feet long, as long as a truck. Due to its over all squid-like appearance, Cameroceras was a distant ancestor of modern day squid and cuttlefish. They caught prey with their tentacles and they drug their prey back to their mouth where there's a beak, just like modern day squids. 

Cameroceras spent a lot of time in deep water. Because light didn't penetrate to well down in deep waters, so their eyes didn't work well so they relied on another sense. They actually smelled out their prey and then crush them to bits. Although these sea monsters are the top predators of Ordovician times, they couldn't swim very fast.
