#fossilfriday An example of why the ANSP and its collections must be saved. Atlantochelys mortoni, a giant protostegid sea turtle - named in 1849 by Agassiz based on the proximal humerus fragment. In 2012, someone found a large distal humerus that FIT ONTO THE SAME BONE in ANSP collections. 1/ 🦖🧪
The reunited humerus of the gigantic sea turtle Atlantochelys, on display in a museum: you can clearly see the break that happened sometime prior to the 19th century.

I've worked for a natural history museum for 11 years at this point (man, yikes) and while it is sad, it isn't surprising to see two major institutions facing closure this year.

11/ In Summer 2023, I finally saw the specimen again with @ashpoust.bsky.social at UCMP! We're working on redescribing the specimen and it's circuitous history, along with describing many additional teeth and postcrania. This species is known to be a maximum of 500,000 years old.

1) Don't wait until a museum is closed or threatened with closure to support it and speak out for it. By that point, it's often too late, and if it's not too late, the path out of the trouble is way harder and more expensive than avoiding the crisis.

A watercolor painting of a fossil whale skull with mandibles in a massive block of greenish gray sand. The skull is incomplete, and the left mandible is in life position; the right mandible is flipped 180. A cluster of vertebrae are present near the braincase.

For #FossilFriday, here's some 2019 #paleoart of Deinonychus subduing a juvenile Sauroposeidon using the Raptor Prey Restraint (RPR) model of dromaeosaur predation: grabbing prey with taloned feet, pinning it down with its body weight, and then eating it alive. Just like modern raptors, then.
A yellowish feathered predatory dinosaur has leapt onto the back of a small long-necked dinosaur, forcing it roughly to the ground. It has grasped the back of the herbivore with taloned feet, and holds its wings out for stability. Dust swirls around them as they wrestle.

As both an academic and a writer, I am repelled by the "this looks like a long document. Would you like me to summarize it for you?" that seems to appear at the top of every pdf viewer now. NO. The *entire point* of good writing (either books or journal papers) is that every sentence has a purpose.

A scientific paper already has a carefully thought out abstract & conclusions I can look at if I want an overview. A book is supposed to be a joy to read, an intellectual and emotional experience to relish. This is not something that advanced statistics can either add to or improve on.
