MANSOURASAURUS

Mansourasaurus shahinae hails from the late Campanian rocks of Egypt’s Western Desert, and represents the most complete African dinosaur specimen currently known from the PPC (post-Cenomanian Cretaceous—94-66 million years ago) of the African mainland. This medium-sized titanosaur—about the weight of a modern elephant—was preserved as a partial skeleton including skull fragments, neck and back vertebrae, ribs, limb bones, and even pieces of dermal armor, but the bone surfaces still showed the open sutures of an animal not yet fully grown. Its remains, drawn from the Quseir Formation, anchor a rare glimpse of life in a region whose Late Cretaceous fossil record is famously sparse.

The anatomy of Mansourasaurus reveals a dinosaur still connected to the wider world. Detailed comparisons show it shares more features with European titanosaurs than with those from South America, suggesting that northern Africa retained biogeographic ties to Eurasia even as the continents drifted toward their final Cretaceous positions. Named for Mansoura University and honoring Mona Shahin, a founder of its vertebrate paleontology center, the discovery marks a turning point: a well-preserved, well-dated sauropod that helps clarify how African ecosystems evolved in the final chapters before the end-Cretaceous extinction.
