The Triassic echinoids of North America

The Triassic echinoids of North America
Journal of Paleontology (1968) 42 (4): 1000-1006


Triassic echinoids are rare, particularly in North America where only two species have been described [from California], both of which are based on [cidaroid] fragments which cannot be generically identified. These fragments are herein reillustrated and redescribed. More than two hundred specimens of a new genus and species, Lenticidaris utahensis, have been found in the Early Triassic Virgin Formation of Utah. This species belongs to the family Miocidaridae and is unique in having a highly flexible adapical surface.
