I missed #MosasaurMonday but holy moly, Winnie is prepped!

Here's the main part of the skull, without the palate laid out. She came out great and im so happy she's covered in pathologies. Just like me, we both have interesting skeletal injuries. Lower Niobrara, 86.5 million years old 🧪

This striped formation may contain the oldest intact rocks on Earth.* A new study suggests that they are at least 4.16 billion years old--relics from a time before plate tectonics, probably before oceans, even.

Every study about vaccines that comes out is like "this vaccine is 97% effective at preventing this disease & also 3 other diseases & it somehow helps you play the violin beautifully" and antivaxxers are doing their own research that's telling them they can cure measles by eating polar bear liver.

RFK has announced that he is developing a vaccine against all viruses. Yes, every single one. The whole, uh, "phylum"

Happy #FossilFriday from the BEST fossil shark specimen on display anywhere (it’s at KU)

This Cretoxyrhina mantelli skeleton has the bones of a big Xiphactinus audax mixed in with it, showing the shark died shortly after ingesting the absolute worst fish in the late Cretaceous seaway. 🧪🦈

The White House has instructed NASA to terminate two major, climate change-focused satellite missions. They've been collecting widely-used data, providing both oil and gas companies and farmers with detailed information about the distribution of carbon dioxide and how it can affect crop health.
