Throwback! ๐ฆ Happy weekend to all of my lovely followers! โค๏ธ Hope youโre having an amazing weekend!
A major update in dinosaur science: researchers have described a new species, Spinosaurus mirabilis, from 95 million-year-old river deposits in what is now the Sahara Desert of Niger - the first new Spinosaurus species recognized in more than a century.
This theropod stood out for its tall scimitar-shaped head crest and interdigitating teeth, specialized for catching large fish. Unlike earlier ideas that spinosaurs were fully aquatic swimmers, S. mirabilis appears to have been a semi-aquatic wader, moving through inland rivers much like a modern heron.
Estimated at roughly 10โ14 meters long and 5โ7 tons, this species gives us fresh insight into spinosaurid diversity and how these giants lived and hunted in ancient freshwater ecosystems.
