A fossilized oviraptor nest and six eggs were unveiled Nov. 15 at the Sherman Dugan Museum of Geology at the San Juan College School of Energy.
Paradictyoolithus is an oogenus of dictyoolithid dinosaur egg from the Zhejiang Province, China. They are nearly spherical eggs, measuring up to 13.9 cm (5.5 in) in diameter, and have a thin eggshell. Their shells are made up of three or four superimposed layers of eggshell units. The two known oospecies are distinguished mainly by their pore ...
Phaceloolithus is nearly spherical, measuring 167–168 mm long and 140–150 mm across. The eggshell is very thin, measuring from 0.5 to 0.7 mm thick. [1] Like most other non-avian dinosaur eggs, [3] Phaceloolithus's shell is stratified into two layers: the prismatic layer on the outside, and the mammillary layer on the inside. [1]
Dictyoolithus eggs are roughly spherical and measure from 12–16 centimetres (4.7–6.3 in) in diameter. [2] Their eggshell is between 2.5 and 2.8 mm thick. The surface ornamentation is smooth with a grainy texture, or has very low rounded nodes. The eggshell is notable for being composed of more than five superimposed layers of eggshell units ...
The previous record for the smallest non-avian dinosaur egg, according to Guinness World Records, measures 45-by-20 millimeters (about 1.77-by-0.79 inches). Discovered in Japan's Tamba City, this ...
Egg measures less than 30mm long
Nipponoolithus rumosus is known only from a handful of isolated eggshell fragments ranging from 0.36 to 0.53 mm in thickness, just barely larger than a chicken egg. [1] [4] It is estimated, based on the eggshell thickness, that Nipponoolithus eggs weighed about 100 grams (3.5 oz), making it among the smallest fossil dinosaur eggs ever discovered.
Elongatoolithus is an oogenus of dinosaur eggs found in the Late Cretaceous formations of China and Mongolia. Like other elongatoolithids, they were laid by small theropods (probably oviraptorosaurs), and were cared for and incubated by their parents until hatching.
