It’s the late Jurassic Period in the super continent of Laurasia, some 85 million years into the reign of the dinosaurs.

When mammals were emerging, Gondwana encompassed Africa, India, Australia and South America and was far larger than Laurasia in the Northern Hemisphere.

A diverse collection of ankylosaurs once roamed in great numbers across Laurasia — the northern supercontinent that once contained North America and Asia.

But the discovery of Messelopython freyi flips that idea on its head — it now looks like pythons originated instead in the supercontinent known as Laurasia, which was composed of North America, Europe and Asia.

The evolutionary outline, in its current form, indicates that eastern Laurasia was the center of origin for various Early Cretaceous animals that then spread outward through the continent.
