Tomeia is an extinct genus of capitosaur that lived during the Olenekian stage of the Early Triassic epoch. [1]

Description

Tomeia differs from other capitosaurs in its short suture between the parasphenoid and pterygoid, its intervening margin of parasphenoid that blocks ventral contact between the pterygoid and exoccipital, its pronounced ornamentation on the ventral surface of the parasphenoid, its more dorsally located oblique ridge relative to other capitosaurs, its slit-like posttemporal fenestra, and the exceptionally large size of its paraquadrate foramen when compared with the accessory paraquadrate foramen. [2]
