Spinosaurus Fossil: ‘Giant Swimming Dinosaur’ Unearthed

 

 

 

” A giant fossil, unearthed in the Sahara desert, has given scientists an unprecedented look at the largest-known carnivorous dinosaur:Spinosaurus.

The 95-million-year-old remains confirm a long-held theory: that this is the first-known swimming dinosaur.

  Scientists say the beast had flat, paddle-like feet and nostrils on top of its crocodilian head that would allow it to submerge with ease.  

  Lead author Nizar Ibrahim, a palaeontologist from the University of Chicago, said: “It is a really bizarre dinosaur – there’s no real blueprint for it.”

” It has a long neck, a long trunk, a long tail, a 7ft (2m) sail on its back and a snout like a crocodile.

” And when we look at the body proportions, the animal was clearly not as agile on land as other dinosaurs were, so I think it spent a substantial amount of time in the water.” 

The team says that Spinosaurus was a fearsome beast.

  The researchers say that, at more than 15m (50ft) from nose to tail, it was potentially the largest of all the carnivorous dinosaurs – bigger even than the mighty Tyrannosaurus rex. ”
