Porituberoolithus
Porituberoolithus is an oogenus of dinosaur egg found in the late Campanian Oldman Formation and Dinosaur [Park Formation] of Alberta, the Fossil Forest Member of the Fruitland Formation in New Mexico, the Upper Shale Member of the Aguja Formation in Texas and Cerro [del Pueblo Formation] of Mexico. It was originally described as distinct from the Elongatoolithids on the basis of its ornamentation, but it was listed as a member of that oofamily by Wang et al. 2010. It is very similar to Subtiliolithus, but has a thicker shell.
