Crania is an extinct genus of brachiopods that lived during the Upper Cretaceous.
Description
Crania has small (up to 2 centimetres or 0.79 inches in diameter) circular shells. The dorsal valve is smooth or has slight pustules. The ventral valve is only attached posteriorly and has a thickened flat grainy rim.[1]
Reassigned species
As the genus Crania was erected early on in paleontology, many species have since be reassigned.[1][3]
