Palaeontologists have discovered a colossal new species of dinosaur in a remote part of the Sahara. Named Spinosaurus mirabilis meaning astonishing Spinosaurus in Latin the giant lived in what is now Niger more than 95 million years ago, far from the coastal regions where similar fish-hunting dinosaurs are usually found.
As long as a school bus and weighing several tonnes, the new species is easily distinguishable from other spinosaurs by the scimitar-shaped crest on its head. The feature was so unusual that researchers didnt recognise it when they first unearthed it in 2019, only realising its significance after returning in 2022 to find more specimens.
This find was so sudden and amazing, it was really emotional for our team, said Paul Sereno, a professor of organismal biology and anatomy at the University of Chicago. Sereno led the discovery, which was published in a study in Science.
Ill forever cherish the moment in camp when we crowded around a laptop to look at the new species for the first time, after one member of our team generated 3D digital models of the bones we found to assemble the skull... Thats when the significance of the discovery really registered, he added.
