US, WASHINGTON (NEWS OBSERVATORY) — In southwestern Japan, paleontologists found the shell of the smallest dinosaur egg known to science. It belonged to the flightless dinosaur Hime Lithus murakami, which lived at the end of the Lower Cretaceous, more than 106 million years ago.
The article describing the find was published by the scientific journal Cretaceous Research, Kyodo writes briefly about this.
According to shell fragments, paleontologists calculated that the size of the egg was about 4.5 by 2 cm, and the mass was about 10 g. Scientists have found similar small fossils before, but most of the samples were twice as large and weighed about 30 g.
In total, scientists found four fossilized eggs and more than 1.3 thousand fragments of shells. Scientists believe that the eggs belonged to a small flightless theropod. This suborder included predatory dinosaurs that moved on two legs.
Paleontologists find the remains of such reptiles much less often than the fossils of larger dinosaurs – for example, tyrannosaurs. The current finding suggests that small dinosaurs settled in groups and laid eggs together, scientists say.
