#Fossil Discovery Rewrites Global #Dinosaur History sciencealert.com/fossil-discov paper: academic.oup.com/zoolinnean/ar

"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."

Comprehensive analysis reveals hidden genomic #evolution of brown algae phys.org/news/2024-12-comprehe

Evolutionary #genomics of the emergence of #BrownAlgae as key components of coastal ecosystems cell.com/cell/fulltext/S0092-8

"450 million years ago, brown #algae transitioned from unicellular to simple multicellular forms. This was driven by #HorizontalGeneTransfer from #bacteria... Around 200 million years ago, following the breakup of #Pangea, brown algae underwent significant species diversification"

Therapsids Originated in Tropical Rather than Temperate Regions sci.news/paleontology/mallorca

Early–middle Permian Mediterranean gorgonopsian suggests an equatorial origin of therapsids nature.com/articles/s41467-024

"#Therapsids were a dominant component of #Permian terrestrial ecosystems, eventually giving rise to #mammals during the early #Mesozoic... #Paleontologists have discovered a #NewSpecies of early #gorgonopsian #therapsid that was part of an ancient summer wet biome of equatorial #Pangea"

A diadectid skin impression and its implications for the evolutionary origin of epidermal scales royalsocietypublishing.org/doi

"the epidermal scales in #diadectids and other terrestrial #tetrapods prevented the evaporation of water from their bodies, which may have helped them survive the #desert climate that prevailed on #Pangea during the #Permian"
