SAS INAH The exact identity of Yatzila remains unknown, and researchers hope a 2027 expedition will allow them to extract a tooth for ancient DNA analysis. For the time being, the team has refrained from removing the remains, retrieving only a single...

Biomechanical modeling of the damage indicates the predator exerted a force approaching or exceeding 40,000 newtons per tooth, a level of pressure consistent with Purussaurus’s known bite strength. Evidence on a Pericotoxodon femur and two astrapothere...

Shaker and his colleagues noted that the creature possessed an exceptionally long, slender jaw equipped with more than 20 tooth positions on each side. While this design likely allowed for swift strikes, the structure suggests a lighter bite force...

Sereno’s interest in the region dates back to a 1950s report by French geologist Hugues Faure, who noted a dinosaur tooth from Niger. “It felt like searching for a needle in a haystack,” Sereno said of the long‑term quest. Today, the Jenguebi locality...
