Anomolacarids ... the apex predator of the Cambrian oceans (550 million years ago). Occasionally, you will find a trilobite fossil with a bite taken out of it ... small enough that it survived a bit longer.

Treasure those fossils.

There are many anomolacarids, this is a couple of them.

Anomolacarid fossils are so breathtakingly rare, even a large museum may only have a small piece of this predator arthropod.

They have found at least one complete Anomalocaris fossil.
