The age of dinosaurs ended millions of years ago, but archaeologists continue to strive to capture their immense diversity. A report published last month officially recognizes Spinosaurus as the largest known carnivorous dinosaur in scientific history.
This two-legged beast first emerged in fossils described by German archaeologist Ernst Stromer in 1915. He noted that this theropod (identified as a bipedal carnivore) was larger than the fearsome Tyrannosaurus rex, but the first bones of Spinosaurus were destroyed during Allied bombings in 1944. As a result, the Tyrannosaurus rex maintained its title as the largest land-dwelling carnivore.
That title was later handed over to Giganotosaurus 11 years ago.
Now, Cristiano Dal Sasso from the Civil Natural History Museum in Milan states that Giganotosaurus has been dethroned based on assumptions from new skull findings of Spinosaurus.
