Taxonomic Study of Small Reptile and Amphibian Fossils

Institute of Natural and Environmental Sciences

Professor Tadahiro Ikeda

Fossils of a wide variety of animals—including dinosaurs, frogs, and lizards—have been discovered from the Oyama Formation of the Sasayama Group (Early Cretaceous, approximately 110 million years ago), which is distributed across Tamba City and Tamba-Sasayama City in Hyogo Prefecture.
I am conducting research to identify what kinds of organisms these fossils represent.
Fossil records from this time period are extremely rare worldwide, and the findings from this study contribute to answering various questions related to the evolutionary history of these animal groups, past biodiversity, and paleobiogeography.
