Diatoms are cosmopolitan and a widely spread microbe that form a glass shell around them, a silica. They are the pioneer in most sources of water. It's not hard to imagine that they maybe one of the earliest lifeform back then too.

You know what’s crazy, I don’t think RFK Jr actually believes anything he says after seeing this. He’s just a puppet for the Republican party.

Give YOUR feedback to Iowa about the prospect of removing evolution and climate change education from their education standards!

Imagine discussing biology without references to its foundational concept 😂

“We’re removing references to gravity from intro to physics”
Meanwhile in Iowa they are removing climate change, human impact on climate change, and references to evolution from our state's education standards. You can provide feedback by Feb. 3: www.surveymonkey.com/r/GHS2RYC

In a victory for wistful nostalgics in the palaeontology world, a new paper suggests resurrecting the genus Diatryma (formerly lumped into Gastornis) based on a good number of skeletal differences. Lots of lovely figures in this one, congrats to the authors!

This is not a model. Or a shabby taxidermized modern rhino. This is a "fossilised" Woolly Rhinoceros, discovered in Starunia mine in Carpathian Ukraine (then Poland) in 1929. Dating to the Pleistocene, its exquisite preservation is owed to a mixture of brine, oil & clay. Held on display in Krakow. 🧵

Happy Thanksgiving from your friends at WitmerLab! Lots to be thankful for, but we'll single out the purity of the animals we study & of the scientific riddles they pose. The animals themselves have no politics, no nationality, no religion, no judgement, no baggage. And many of them are delicious! 🦃

#HappyThanksgiving from WitmerLab! You have your holiday traditions, and we have ours! Yes, we CT scanned our turkey on our best turkey platter. Science has never been so delicious! And like any good dinosaur biologist, I prepared and accessioned the skeleton—OUVC 10789. 🦃🦖
