Geniculigypa, a new gypidulid (Brachiopoda) genus from the Middle Devonian of Michigan
Published online by Cambridge University Press: 14 July 2015
Abstract
A new genus, Geniculigypa, and a new subfamily, the Geniculigypinae, are established. Both taxa are monotypic and have as their type species, Sieberella newtonensis Imbrie, 1959, from the Newton Creek Limestone (early Givetian) of Michigan. This species dramatically differs from all other known gypiduloid species in its possession of a prominent geniculation in both valves and by its radially grooved micro-ornament.
