A middle Campanian (Late Cretaceous) fossil discovery from the Himenoura Group in Kagoshima Prefecture, Japan. The dataset describes a new cimolodontan multituberculate mammal species, Koshikibaatar kashimaensis, based on dentary and dental characteristics. It was authored by Takuma Sera and published on figshare in May 2026.
Use Cases
- Comparative phylogenetic analysis based on described dental and mandibular characteristics.
- Studying the biogeographic distribution of multituberculates based on the new Japanese fossil record.
- Reconstructing evolutionary relationships within Cimolodonta based on plesiomorphic traits.
- Investigating Late Cretaceous Asian mammalian diversity based on the newly described species.
Strengths
- Includes detailed morphological description of a new species, Koshikibaatar kashimaensis.
- Data is openly available under a CC-BY-4.0 license.
