Pseudomegaloolithus

Vianey-Liaud and Garcia 2003

Pseudomegaloolithus is an oogenus of fossil Megaloolithid egg from Morocco. It is known from eggshell fragments which are distinguished from other Megaloolithid eggs because of its thin shells, fan-shaped eggshell units, and the structure of the nodes and ridges on the eggshell surface. Some egg fragments from India, France, and Peru may actually represent specimens of Pseudomegaloolithus.
