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 10 cm (4 inches) in diameter. [2] This oospecies has been initially attributed to " hypsilophodontid" dinosaurs, although a lack of associated embryo material currently makes confirming the egg-layer's identity impossible, [1] but now is known to be theropod after the finding in Portugal, [3] associated with the embryos.
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]
