Facts about British palaeontologist. Contrary to popular myth, Mary Anning wasn't a forgotten figure. Her contributions were cited in journals. She had species named after her in her lifetime and featured in non-academic literature. Including Charles Dickens' magazine "All the Year Round"
Natalia (娜塔莉)@wrycritic.bsky.social · 4w agoWeird facts about early British Palaeontologists. Adam Sedgwick, accepting the position of Professor of Geology at Cambridge, had to be celibate & married to his work. William Buckland (father of dinosaurs) decided to name 1 of his 9 kids, Adam Sedgwick Buckland, to compensate for his lack of heirs.

Transitions between persistent climate–carbon regimes coincide with elevated Phanerozoic biosphere vulnerability - Nature Communications
Earth’s climate over the past 539 million years (the Phanerozoic Eon) occupied a few long-lived “mega-climate” regimes. This study shows that life was most vulnerable to extinction during the relative...

The Friends of UMMP BBQ was a success. I am tired. No one went home hungry. I have a few new fossils. The trilobite cookies were amazing. Time for sleeping.
Another paper from our NASA-funded project on ferns has dropped! UWyoming MS student Fern (really!) Holian, developed a new schema for classifying fossil ferns, which are understudied. 🧪🌿☄️
