ostracods, a small crustacean that remains common today (there are 13,000 existing ostracod species). Some of these appear to be larval versions of the animal. There are also fragments of thin shells that probably were derived from shellfish like clams and mussels, as well as some pieces of an echinoderm (think starfish and sea urchins).

Overall, the most striking thing about the food present is the sheer variety of it. It appears as if the animal hoovered up anything with a shell it came across on the floor of the body of water it was living in.
