Triops is often called a living fossil. In fact, the species Triops cancriformis has been identified in rocks as old as the Triassic. To be frank, this is bullshit and lazy taxonomy. The fossils differ in several regards from modern Triops, and seem to warrant a new generic assignment. Curiously, the fossils in question are North American, but are assigned to the Eurasian species of Triops . . .
