The type species, Glyptops plicatulus, was first described as Compsemys plicatulus by Edward Drinker Cope on the basis of AMNH 6099, a partial shell from the Late Jurassic (Tithonian) aged Morrison Formation of Colorado.[1] In 1890, a partial skull, YPM 1784 (described from Como Bluff, Wyoming), was named Glyptops ornatus by Othniel Charles Marsh.[2] Later, Oliver Perry Hay recognized Compsemys plicatulus and Glyptops ornatus as being from the same species, hence the new combination G. plicatulus.[3] Another Morrison species of Glyptops, G. utahensis, was described from a complete shell (CM 3412) found at Dinosaur National Monument in Utah.[4]Glyptops later became a wastebasket taxon to refer to isolated shell fragments with a finely sculpted surface texture. The type of Glyptops plicatulus was later judged to be a nomen dubium, due to it lacking any diagnostic characters, and Glyptops ornatus was made to be the only valid species.[5]
The species Glytops caelatus Hay, 1908 was described from the middle Cretaceous (late Aptian-early Albian) Arundel Formation of Maryland. However, it was later dismissed as a nomen dubium based on non-diagnostic remains.[6]
Descriptionedit
The skull of Glyptops ornatus exhibit adaptions likely for suction feeding.[5]
