Doryaspis swim amongst a bed of Anthozoa

8-inch-long jawless fish of the genus Doryaspis swim amongst a bed of Anthozoa of the order Actiniaria (AKA sea anemones) 410 million years ago in what is today the Svalbard archipelago in Norway. Doryaspis (AKA Lyktaspis) was armored with bony spines and a long snout that had spines set along its length (somewhat like the saw of a modern sawfish). Doryaspis mouth opened above, rather than below the snout, and is believed to have dined on plankton. However the snout may have been used to stir up small crustaceans from the mud or sand.
In addition to a variety of anemones are palm-like crinoids (class Crinoidea), pentagonal-shaped sea stars, nautilus-like ammonites, and squid-like nautiloid cephalopods of the genus Orthoceras

An Anomalocaris explores a Middle Cambrian age ocean floor

An Anomalocaris explores a Middle Cambrian ocean floor about 500 million years ago. Growing to over three feet long, Anomalocaris is believed to have been a predator whose diet included trilobites. Anomalocaris may have also been one of the earliest arthropods.
This image includes an Olenoides serratus trilobite and sponges genus Vauxia and Wapkia. The small, flower-like animals (yes, like the sponges they are rooted animals) are from the genus Dinomischus. Above and behind the Anomalocaris is an ancient jellyfish
