Scientists have discovered the first dinosaur which was able to swim and feed on underwater creatures. Fossil remains of this 15-meter (45 feet) long giant, called Spinosaurus, were discovered off the eastern coast of Morocco.
The fossils were found in 97-million-year-old freshwater sediments. The findings are reported in the September 11 issue of the journal Science.
Bigger than Tyrannosaurus rex, this aqua-dino had clear adaptations for preying in water. It had a small nostril located far back on the head, so that it could breathe and prevent excessive water intake. Along with relatively long forelimbs, it had big flat feet suitable for paddling as well as walking on muddy ground. The limb bones have been found to be very dense helping in remaining underwater rather than float at the surface. These adaptations resemble those of early whales and today’s hippopotamus.
