Crustacean,

Isopods date back to the Carboniferous Period – first-known from the Mazon Creek fauna.  They are uncommon in the fossil record tending to be found only in certain deposits.  Biologists have studied modern deepwater specimens the size of a lobster but most are small like the “pill bugs” you found in your grandparents’ garden.
