Glad to share our new study at "Nature Communications" which resulted from several workshops on the early warning signs of mass extinctions and coordination of macroevolutionary vulnerability and the states of carbon cycle and temperatures. https://www.nature.com/articles/s41467-026-75655-9 🧪⚒️ #Geology #Paleobio #EvoBio

"appearance of the new apex predator cf. Saurosphargidae relatively soon after the [P\Tr] extinction event coincides with the reappearance of predatory cephalopods and precedes the full ecological and taxonomic recovery of benthic groups in the Dolomites" https://tandfonline.com/doi/full/10.1080/02724634.2026.2685335 🧪⚒️ #Paleobio

"...results contrast with the common view that the geo-logically stable Proterozoic Era experienced little eukaryotic evolutionary innovation and indicate that all current supergroups were already established in the Mesoproterozoic." 🧪⚒️ #Geology #Paleobio https://www.pnas.org/doi/epdf/10.1073/pnas.2600283123

"We describe the only known example of a three-dimensionally mineralized heart, thick-walled stomach, and bilobed liver from arthrodire placoderms, stem gnathostomes from the Late Devonian Gogo Formation in Western Australia" https://www.science.org/doi/epdf/10.1126/science.abf3289 🧪 ⚒️ #Geology #Paleobio #EvoBio
