Gara Sbaa Member, Akrabou Formation

Undescribed 10mm positive marine isopod
Crustacean,

Isopods belong to an order of crustaceans that dates back to the Carboniferous Period and still live today.  They are uncommon across the fossil record tending to be found mostly in certain deposits.  Biologists have studied modern deepwater ones the size of a lobster but most are small like the “pill bugs” you found in your grandparents’ garden. Compare to the picture of the living marine isopod to get an idea what this monster looked like.
