Dinosaurs of Gondwana

The Osaka Museum of Natural History is currently exhibiting some extraordinary dinosaurs from the super continent of Gondwana.
They really grab your attention.

Malawisaurus Dixeyi, a smaller titanosaur, still huge.

Stegasaurus' head was about the same size as the head of a large dog.

Suchomimus (crocodile mimic), a relative of Spinosaurus, appears to be specialized in catching fish, and has teeth of the same kind and arrangement as modern crocodiles.

Aucasaurus Garridoi, looked to have even smaller arms than T. Rex.
It also appeared that most of the lower arm bones were fused together.

Mapusaurus Roseae, a huge meat eating dinosaur, having larger arms and more blade-like teeth than T. Rex. The smaller dinosaur in the lower right is a juvenile of the same species.

Gigantosaurus carolinii, bigger than the Mapusaurus above, it was even larger than the Tyranosaurus Rex, with a skull 1.8m (6ft) long.


Not the biggest predator but certainly very fast and able to chase down whatever it wanted to, and long arms to grab its prey.
Deltadromeus agilis.

Unenlagia comahuensis, a dromaeosaur, which was feathered but did not fly. Rather, it ran around chasing other flightless bird like dinosaurs. At 2m in length it's a bit like a lion, only faster with arms and sickle like claws on its feet.

Anabisetia saldiviai, lunch for Unenlagai.

A recent find from Morocco,
Carcharodontosaurus saharicus, 'shark toothed lizard of the Sahara'

What Carcharodontosaurus would have looked like before it ate you.
