Buried in the Sahara, Nat Geo explorer Paul Sereno and his team uncovered 55 tons of dinosaur fossils—including a Spinosaurus skull and one of Africa's earliest giant predators. These finds are helping rewrite the story of prehistoric life in Africa. 🔗 on.natgeo.com/4nPKCFF

You'll all have seen the many announcements and PR pieces from #ColossalBiosciences. There are reasons to be concerned about the general message promoted by CB, one being that it's seen >by some< (US politicians in particular) as meaning that we can devalue conservation. 🧵1/n

I commissioned this from Matt as a resource for the entire art community. To my knowledge there was no full body lizard muscular anatomy reference until now.

Here's a look at a cool thing I've been working on for @arvalis. Lizard anatomy is well studied/figured, but many of the resources are hidden in literature that may be unknown/inaccessible to artists. The mission was to make an idealised, artist-friendly ref for lizard muscles.🦎

So you wanna draw a pterosaur (accurately)? A thread of published, visual resources that you might find useful. Starting with musculature reconstructions from Pterosaurs: Natural History, Evolution, Anatomy (Witton, 2013)

Can 50 tons of dinosaur fossils help hatch paleontology in Niger?

Can 50 tons of dinosaur fossils help hatch paleontology in Niger?

Landlocked Niger is home to stunning dinosaur fossils. Scientists aim not only to find them but also to build homegrown research expertise.

Replying to @BiologyCarly
While on fieldwork I collected a big dead cormorant for dissection and brought it back to our building at night. But the grounds were locked so I had to lob it over the wall and aim to retrieve it the next day. It was in a large sack. Security found it, I got in trouble.

My first (public) skeletal of 2023 - Suchomimus tenerensis! This is a little update from the last, more S curved neck, and a few general changes based on the scanned material published in the new Spinosaurus paper! Scale bar is 1 metre, based on holotype specimen.
