"Ahvaytum bahndooiveche is now the oldest-known dinosaur from #Laurasia, the Northern Hemisphere land mass of the late Paleozoic supercontinent #Pangea... That age places it in a similar time period to #dinosaurs of Pangea's Southern Hemisphere land mass, #Gondwana, which were thought to be the world's first by a long shot."
Fossil Discovery Rewrites Global Dinosaur History
Just a few fossil fragments of a tiny creature discovered thousands of miles north of its contemporaries have shaken our understanding of global dinosaur history.

"they were previously thought to have emerged on the #supercontinent #Gondwana, in what is present-day #Australia. However, the new study indicates their common ancestor may have originated in the northern hemisphere, on the supercontinent #Laurasia, before spreading out further into the world."
Study shows orchid family emerged in northern hemisphere and thrived alongside dinosaurs for 20 million years
In a new study published in New Phytologist, scientists at the Royal Botanic Gardens, Kew, along with partners in Latin America, Asia and Australia, present an updated family tree of orchids, tracing their origins to the northern hemisphere some 85 million years ago. Not only does the study shed new light on their complex and fascinating evolutionary history, but the study's authors hope their findings will help inform future orchid conservation planning.
Fossil of Giant #Triassic #Amphibian Unearthed in Brazil

Interrelationships among Early Triassic faunas of Western #Gondwana and #Laurasia as illuminated by a new South American benthosuchid temnospondyl https://anatomypubs.onlinelibrary.wiley.com/doi/10.1002/ar.25384
"Named #Kwatisuchus rosai, the #animal was approximately 1.5 m in length. It belonged to #Benthosuchidae, a small group of giant #crocodile-like #amphibians that lived during the Triassic. They were primarily aquatic, living in rivers and lakes."

A new genus and species of temnospondyl amphibian has been described by a team of paleontologists from the Universidade Federal do Pampa, the Universidade Federal do Vale do São Francisco, Princeton University and Harvard University.
Now the more #riebeckite facies of the #Paleozoic #Quincy #Granite
The Quincy granite was a prized architectural stone, most famously used in the #BunkerHill Monument in #Boston #Massachusetts. Current dating suggests it was intruded into #Avalonia before it glommed onto #Laurentia as #Laurasia and #Pangea were assembled. Today’s #photo set comes from a walk around the eponymous Bunker Hill Quarry. I’ll post more about the history later. Captions!

New enantiornithine #bird from the the uppermost #Cretaceous of southern #Patagonia, #Argentina https://www.sciencedirect.com/science/article/abs/pii/S0195667122003160
#Yatenavis shares morphological features with Late Cretaceous #enantiornithines found at diverse localities, including #Madagascar, North America, Patagonia, and #CentralAsia. This may indicate the presence of an enantiornithine subclade widely distributed across #Gondwana and #Laurasia.
