At this time, tectonic movements had arranged most of Earth's landmasses into two vast supercontinents: Laurasia in the north and Gondwana in the south.

Evidence of the earliest dinosaurs have been found in southern Gondwana, while other fossils of close relatives have been identified Laurasia. The researchers suspect that if and when any dinosaur ...

A new study published in the Zoological Journal of the Linnean Society suggests that dinosaurs roamed Laurasia earlier than scientists thought.

A huge dinosaur skull found in southern China appears to belong to an entirely new species, according to a group of paleontologists that studied the specimen. Paleontologists found the fossilized ...

According to the University, the mainstream belief is that dinosaurs first spread to Laurasia, the northern part of the ancient supercontinent of Pangea, millions of years after emerging in Gondwana, ...

Paleontologists generally believe that dinosaurs first evolved in the southern part of the supercontinent, Pangea, around 230 million years ago. This region was known as Gondwana, and dinosaurs ...

Prior to the latest study, the available evidence suggested that the oldest known dinosaurs from Laurasia—primarily situated in the northern hemisphere—did not appear until 6–10 million ...

The team identified an early dinosaur-like footprint in older rock layers, meaning that dinosaurs or dinosaur-related creatures were calling Laurasia home even before Ahvaytum.
