The myodocope ostracode Entomozoe from an early Silurian (Telychian, Llandovery) carbonate mound of the Samuelsen Høj Formation, North Greenland

Abstract

Entomozoe aff. Entomozoe tuberosa (Jones 1861), from carbonate mounds of the Samuelsen Høj Formation, represents one of the few ostracodes documented from the Silurian of Greenland and a rare occurrence of Entomozoe from outside Scotland. Like its coeval, congeneric Scottish counterparts, the Greenland Entomozoe lived on a shallow-water shelf dominated by epibenthonic fauna and probably had a benthonic, swimming(?) lifestyle. Its environmental, ecological and geographical setting is consistent with the idea that these earliest, Lower Silurian myodocopes were benthonic and, therefore, that Upper Silurian pelagic representatives must have resulted from an ecological shift in the group.
