| — Allen, about Cameroceras in Eye of the Beast | ||
Cameroceras (name meaning "Chambered Horn") also called the Giant Orthocone, is a genus of giant orthoconic cephalopod that originated during the Late Ordovician Era in what is now North America and Asia. Measuring well over 9 meters long and weighing around a ton, not only was this the largest and apex predator of its day as well as the largest known giant orthocone, but was also the largest creature to have ever existed on Earth before its extinction. An ancestor of modern-day squid, this prehistoric cephalopod had a keen sense of smell, poor eyesight, and fed on trilobites and sea scorpions.
In the Series 1 episode, Eye of the Beast, a group of four Cameroceras were brought to the park from Late Ordovician North America, 450 million years ago. They reside in the Primeval Aquarium Enclosure.
