Scientists describe a new animal species from Tanzania that dates to about 240 million years ago in the Triassic Period. The fossil is identified as *Dinodontosaurus isiyavamanda*. The discovery adds a previously unknown species and helps refine the chronology of early reptile evolution based on fossil evidence from eastern Africa.
The new species is significant because its broader group was previously known mainly from South America. By linking fossil records from Tanzania and South America, the find suggests that the timing of one key Tanzanian fossil site may need adjustment. In particular, scientists say Tanzania’s oldest dinosaur-related fossils may be younger than earlier estimates by several million years, which would affect how researchers order early dinosaur origins.
Across the two reports, the emphasis differs slightly: one highlights the impact on the dinosaur timeline, while the other focuses on the international team’s description and the site’s age. Both agree that the Tanzanian fossil—its age and its taxonomic placement—drives the reassessment of regional fossil dating and, by extension, early evolutionary timelines.
