70-Million-Year-Old Fossil Discovery In Morocco Points To Lost Dinosaur Highways Across Oceans
Indian Defence Review • • science
Key Points:
- A new titanosaur species, Phosphatotitan khouribgaensis, was discovered in Morocco's Oulad Abdoun Basin, dating back around 70 million years, providing insights into dinosaur evolution and ancient continental connections.
- The fossils were found in phosphate-rich sediments from a warm, shallow sea environment, highlighting the region's dynamic land-sea interface during the Late Cretaceous and Early Paleogene.
- Despite its North African origin, Phosphatotitan shares anatomical traits with South American titanosaurs, suggesting evolutionary links across continents possibly due to shared Gondwanan ancestry or dispersal across marine barriers.
- Phosphatotitan was smaller than its South American relatives, likely reflecting island-like environmental pressures in Late Cretaceous North Africa that promoted smaller body sizes and unique endemic faunas.
- This discovery challenges previous views of dinosaur diversity before the mass extinction, revealing a more complex, regionally specialized ecosystem and emphasizing the need for further fossil exploration in under-sampled areas like Africa.
