A research team formed by paleontologists Nizar Ibrahim and Paul Sereno (University of Chicago), Cristiano Dal Sasso and Simone Maganuco (Natural History Museum of Milan) and Samir Zouhri (University Hassan II in Casablanca, Morocco) found remains of a Spinosaurus aegyptiacus , a dinosaur that existed 95 million years ago during the Cretaceous.
Fossils found in the Sahara have been allowed to know this dinosaur in the aquatic environment was adapted. A telling statistic because it would be the first dinosaur able to live and hunt in the aquatic environment. The remains, have also revealed that this species was three largest m the Tyrannosaurus Rex .
“Working on this animal is like studying an alien from outer space , is unlike any other dinosaur I’ve ever seen, “said paleontologist Ibrahim Serrano. Both Serrano and the rest of the team have based their work on research and compare the samples found with the other parties that exist on this dinosaur. They analyzed a partial skull of Spinosaurus with traces of other museum collections around the world, historical records and images from the first animal was found in Egypt more than 100 years ago.
Its physiological Consitución
According to the reconstruction of the researchers, the Spinosaurus was in the center of the skull small holes that allowed him to breathe as his head was in the water. Neurovascular openings also presented at the end of the muzzle, which would allow detect movement in the water.
His teeth were large and were inclined to the front, a position very favorable for the c Aptura fish , something that also helped her elongated neck and trunk, which made the body mass would shift forward.
The claws that had their limbs made it possible to hunt or cut to the most difficult prey, because his legs were short, although their thighs have the strength to move on land.
Early indications
more than a century ago, the German paleontologist Ernst Stromer von Reichenbach Freiherr Spinosaurus evidence discovered in the Egyptian Sahara. Tests that were destroyed during the allied bombing of April 1944 over Munich, Germany. Despite the apparent destruction, researcher at the University of Chicago, Ibrahim, located notes, sketches and Ibrahim in the archives of Stromer and Stromer the family castle in Bavaria.
The disappearance of this species occurred in end of the Cretaceous . Both the alien or the great volcanic eruption impact (on the two theories advanced to this stage) led to the cessation of photosynthesis and the food chain, as the temperature change that took place destroyed the habitat of these species , which eventually destrurilas themselves.
