"The earliest unequivocal dinosaur fossils appear in the Carnian (∼230 Ma) of southern South America and Africa, leading most authors to propose southwestern Gondwana as the likely center of origin. [...] Our results suggest that the archosaur radiation also took place within low-latitude Gondwana following the end-Permian extinction before lineages dispersed across Pangaea [...]"

A newly described early-middle Permian gorgonopsian from Mallorca, the oldest member of this clade known so far, shows that therapsids likely evolved in paleoequatorial Pangaea!

Nově popsaný mallorcský gorgonopsián ze začátku středního permu, nejstarší dosud známý zástupce tohoto kladu, ukazuje, že therapsidi se pravděpodobně vyvinuli na paleorovníkové Pangaeai!

Nice overview here. I’m particularly pleased that they acknowledge the uncertainty about what #supercontinent will form next: too many stories present one of the possibilities (usually #Pangaea #Ultima) as a near-certainty. We know for sure that there is at least one more supercontinent in #Earth’s future, and probably more, before plate #tectonics stop entirely in a billion years or so. Everything else is informed speculation at best. All this has happened before …

When we think of mountain ranges, we don't usually think of them for what they really are, geological formations that can span the entire planet. However, that's exactly what this map depicts. It shows how the Appalachian mountains in the U.S. actually connect with the Scottish Highlands, the hills of Ireland, Scandinavian Mountains, the east side of Greenland and the Atlas Mountains. When all of these places were once joined together, these ranges formed the Central Pangean Mountains millions of years ago.
