Otero and Emil Krupandan, PhD - student from UCT, were visiting the ESI collections to look at early sauropodomorph dinosaurs when they noticed bones that were distinctive from the other dinosaurs they were studying.

The foot and ankle bone seen here belonged to a large, plant - eating sauropodomorph called Glacialisaurus hammeri, a new genus and species of dinosaur that lived during the Early Jurassic period, approximately 190 million years ago.

Earlier, sometimes bipedal sauropodomorphs called prosauropods, such as Plateosaurus, were large for their time.

Every child learns that dinosaurs fall into two major groups, the Ornithischia (bird - hipped dinosaurs; Stegosaurus, Triceratops, Iguanodon and their kin) and the Saurischia (lizard - hipped dinosaurs; the predatory theropods, such as Tyrannosaurus, and the long - necked sauropodomorphs, including such well - known forms as Diplodocus).

«Sefapanosaurus constitutes a member of the growing list of transitional sauropodomorph dinosaurs from Argentina and South Africa that are increasingly telling us about how they diversified.»

It is considered to be a medium - sized sauropodomorph dinosaur — among the early members of the group that gave rise to the later long necked giants of the Mesozoic.

The paper, titled: «A new basal sauropodiform from South Africa and the phylogenetic relationships of basal sauropodomorphs,» was published online on Tuesday, 23 June 2015.

«This find indicates the importance of relooking at old material that has only been cursorily studied in the past, in order to re-evaluate past preconceptions about sauropodomorph diversity in light of new data.»

Instead, researchers placed theropods with ornithischians, forming a group called Ornithoscelida, and put sauropodomorphs with the early and primitive herrerasaurs.

The «lizard - hipped» saurischians comprised meat - eating theropods such as T. rex and long - necked, herbivorous sauropodomorphs, such as Diplodocus.

While there is limited evidence that some ornithischians may have had feathers, researchers have found no evidence of them on sauropodomorphs.

And it shared some features with other dinosaurs, such as primitive plant - eating sauropodomorphs and a particularly bizarre group of long - necked, vegetarian theropods known as therizinosaurs.

The saurischians can then be further divided into the meat - eating theropods, which includes the Tyrannosaurus, and the long - necked sauropodomorphs, which includes the Brontosaurus.

Dr Alejandro Otero, Argentinian palaeontologist and lead author, says Sefapanosaurus helps to fill the gap between the earliest sauropodomorphs and the gigantic sauropods.

In 1887 Seeley placed the sauropodomorphs (which included the huge «classic» dinosaurs such as Diplodocus and Brontosaurus) together with the theropods (which included T. rex), in the Saurischia.

This new analysis of dinosaurs and their near relatives, published today in the journal Nature, concludes that the ornithischians need to be grouped with the theropods, to the exclusion of the sauropodomorphs.

Sauropodomorphs are known to have coexisted with sauropods, whose members include the long - necked, long - tailed Brachiosaurus and Diplodocus.

New research from scientists at the University of Toronto and researchers in China and Taiwan provides the first evidence that proteins have been preserved within the 195 - million - year - old rib of the sauropodomorph dinosaur Lufengosaurus.

They have also found that Eoraptor was not a predator at all, but a plant - eating sauropodomorph — a lineage that eventually evolved into the gigantic long - necked sauropod dinosaurs.

In Baron's redrawn dinosaur family tree, the saurischians now only include the sauropodomorphs, and the theropods were grouped with ornithischians to form a new classification named ornithoscelidans.
