Scientists have identified a new dinosaur species from a fossil found in Spain. article about it published in Scientific Reports.
Spinosaurids were represented by various dinosaur groups, but were mostly large, bipedal and carnivorous. Spinosaurus and Baryonyx are the best known among the spinosaurids. This family is believed to have originated in Europe and later migrated to Africa and Asia.
Andrés Santos-Cubedo and colleagues analyzed fossil fragments (right jawbone, one tooth, and five vertebrae) that were previously found in the Arcillas de Morella Formation in Spain and dated to the late Barremian to early Cretaceous period (127-126 million years ago). . Based on the remains, it can be concluded that the length of the specimen was from 10 to 11 meters. They compared the specimen to other known spinosaurids to reveal an evolutionary relationship with them.
As a result, the authors concluded that they had a new species and a new genus of spinosaurids, and they named it. Protathlitis cinctorrensis. protalite (genus name) means “champion” in Greek and species Cinctorrensis it takes its name from the city of Sintorres, where it was discovered, for example.
The authors suggest that this new species may point to an early Cretaceous origin of spinosaurids on Laurasia, an ancient continent divided into Eurasia and North America. Spinosaurids may have later migrated to Africa and Asia, where they diversified.
Formerly paleontologists saidwhere live “bagels” live obama 550 million years old.
