Welcome Dinodontosaurus isiyavamanda! I'm delighted to introduce you to a new species of protomammal. Hailing from the Triassic of Tanzania, this is the first record of Dinodontosaurus outside of South America, and it informs on the origin of dinosaurs. Here's a thread summarising our findings 🧵

People should seriously visit the Academy of Natural Sciences while they can. If you are in or near Philly and have time, see it before it’s gone. Also if you think it would be beneficial for it to remain open write Governor @joshshapiropa.bsky.social, Mayor @cherelleparker.bsky.social & Drexel BoS

A fun follow-up: it's fairly well known that John Ostrom was a scientific consultant for the Deinonychus sculpture outside ANSP, but Yale preparator Bob Allen also helped mount the skeleton inside. After a few years he would do the same for the Peabody's own exhibits

Went to Academy of Natural Sciences for work this past
Friday. The highlight was being able to talk with the staff who were some of the most exceptional science communicators I've ever met. The Academy is an incredible bastion of collections, learning, and science. Please support it, it needs us.

Samples from the 90-million-year-old peatland sediments in Antarctica reveal that fire dynamics in the earliest peatlands of the warm, CO₂-rich Cretaceous era closely resembled those of modern ecosystems, according to a paper in Communications Earth & Environment. go.nature.com/3V5GSG0 #Paleosky 🌎🧪

What a neat paper on the beetles of reptiles

Doing my bit to save the Academy of Natural Sciences -- I went on Friday, joined the Academy to help bump their numbers, and am contacting my elected officials and other stakeholders.

Without a concerted public effort, the country's oldest natural history museum will close at the end of the month.

I will not stop talking about the closure of the Academy of Natural Sciences museum until the closure has been cancelled! Here's me on a field trip to the museum in second grade. I now have a Ph.D. in Population Biology. Every evolutionary biologist and ecologist should be bleeting about this!

500k plants, ok, then 6 million fish. Important, sure but that's one uni making a bad choice. Then 7 million fossils and modern mollusks (PRI), 19 million specimens at ANSP, soon we're talking big data right?

specimens you can hold in your hand are real data

For #FossilFriday you are getting something special. Part of the original Dryptosaurus aquilunguis jawbone. First described as Laelaps by Edward Drinker Cope and renamed by his rival Othniel Charles Marsh after it was discovered a mite already named that. Note the tooth! Academy of Natural Sciences
