A Pack of Huge Meat Eating Dinos Found - Mapusaurus roseae
Here’s some BIG dino news for you! Fossils of a new giant carnivore have been found in Argentina. Interestingly, a group of the animals were found together leading researchers to believe they may have hunted in packs.
Paleontologists Rodolfo Coria and Philip Currie recently published their discovery of Mapusaurus roseae in Geodiversitas, A new carcharodontosaurid (Dinosauria,Theropoda) from the Upper Cretaceous of Argentina. [pdf]
Now the question is, who was bigger - Mapusaurus, Giganotosaurus, or Spinosaurus?
The genus name, Mapusaurus, means “Earth Reptile”. It comes from the Mapuche word for earth, mapu. The Mapuches are an indigenous people of Patagonia.
The species name, roseae refers to the rose colored rocks that surround the site where the fossils were found, and to Rose Letwin who sponsored expeditions that lead to the discovery.

If a group of these were found together, surely that would suggest they died together? Or were very territorial….if they died together, was it sudden etc…
Interesting.. : )
