Fossils from Osaka reveal new bones of ancient mosasaur species

15 Ağustos 2026Science Daily

Fossils collected in Osaka over 30 years ago have unveiled four previously unrecognized bones from a giant Cretaceous mosasaur. Notably, this includes the first confirmed premaxilla identified in a Japanese mosasaur fossil.
The skull exhibits unusual anatomical features, suggesting the possibility of an entirely new species.
Mosasaur fossils have been critical in understanding marine life during the Cretaceous period. This finding adds to the body of knowledge regarding the geographical distribution and morphological diversity of these creatures, particularly in Japan, where such discoveries are rare.
The discovery of these fossils not only enhances our understanding of mosasaur diversity but also highlights the potential for significant paleontological finds in previously examined collections. The anatomical anomalies observed could prompt a reevaluation of existing classifications within the mosasaur lineage, i…
