Mollusca is the second-largest phylum of invertebrate animals after the Arthropods and the largest marine phylum. Molluscs include gastropods, cephalopods, and bivalves. The cephalopods, the most advanced class of mollusks, include ammonoids, belemnites as well as the octopus and squid. Nautiloids are the early forms. They get short shrift in the toy companies.

In the Ordovician, primitive nautiloids became the dominant predators, feeding on trilobites and small arthropods from the seabed. These Orthocerida were slender, cylindrical orthocones with very long body chambers. The large 40-foot Cameroceras is commonly portrayed as the top predator for the Ordovician. CollectA is the leader in cephalopod figures. They have Cameroceras included in their Mini Prehistoric Marine Animals box. The company Colorata created a Cameroceras in their paleozoic Creatures release. The related Tomy Michelinoceras, a conjoined pair from their out-of-production “Dinosaur Train” release, are an original configuration, are festive in color and anthropomorphic to appeal to children. The CollectA Orthoceras had ventral siphuncle, ten tentacles equal-sized that were splayed to seize prey, and a dorsal hood in common with the living Nautilus. The shell is banded tan and brown. It is the new king of the Ordovician seas.
