Preprismatoolithus is a Late Jurassic oogenus. The species P. coloradensis is described by John Foster as being "of the prismatic basic type,"[1] with subspherical eggs about 10cm (4 inches) in diameter.[2] This oospecies has been attributed to "hypsilophodontid" dinosaurs, although a lack of associated embryo material currently makes confirming the egg-layer's identity impossible.[1]
Eggshell present in great abundance at the so-called "Young Egg Locality" which seems to have been a dinosaur nesting ground.[1] Congeneric eggshell fossils are found at additional Colorado sites including the Fruita Paleontological Area, the Uravan Locality and Garden Park.[1]
