A 50-foot-long carnivore who hunted its prey in rivers 97 million years ago, the spinosaurus is a "dragon from deep time." Paleontologist Nizar Ibrahim and his crew found new fossils, hidden in cliffs of the Moroccan Sahara desert, that are helping us learn more about the first swimming d...
At the time of discovery, Giganotosaurus was believed to be the largest theropod before the discovery of another carnivorous dinosaur species about two years later. As far as carnivorous dinosaurs go, the semi-aquaticSpinosaurusis the longest. The dinosaur was found in North Africa in about the ...
The researchers used CT scans of dinosaur fossils and modern-day specimens to create a 3D computer model of a dinosaur jaw and identify where muscles attach to bone. They then used the model to simulate muscle forces under different biting scenarios. Stars indicate areas where strain was assessed...
So, as we fleshed out our Spinosaurus -- I'm looking at muscle attachments and wrapping our dinosaur in skin -- we realize that we're dealing with a river monster, a predatory dinosaur, bigger than T. rex, the ruler of this ancient river of giants, feeding on the many aquatic animals...
