Isopod Crustacea in fossil amberDescription: This plaque of amber displays a most uncommon inclusion, commonly called a Slater or Pillbug. Actually it is a member of the Crustacea known as an Isopod. Isopods vary greatly in appearance and are common inhabitants of many environments. Slaters belong to the Crustacea of which most are marine dwellers and includes such groups as amphipods, beach hoppers, shrimp, crabs, lobsters, crayfish as well as isopods. Slaters are one of two groups of Crustacea that have become terrestrial: the Isopoda and the Amphipoda. Slaters are the most conspicuous and are easily recognized by their heavily armored, flattened bodies.

The other inclusions are a pair of tiny wasps, and ant, several flies, and a 3 mm Plant Bug (Hemiptera, Family Miridae).
