Ordovician marine organisms, illustration. The animals at centre are a form of cephalopod. Present-day cephalopods include squid, nautilus, and cuttlefish. In the seas of the Ordovician (485 to 443 million years ago), cephalopods such as Endoceras and Cameroceras were one of the dominant predators, preying on trilobites (one at lower centre), various molluscs (at lower left) and other marine organisms. An ammonite is shown in the background at upper left. | |
