One of them came in with a broken hand ☹️. Thought this may make for a fun paleoart opportunity 👀

Very happy to hear that the Maryland Dinosaur Park's discovery trail is now open! Congratulations to everyone there for *finally* making this happen. The sculptures by Tristan Crum look phenomenal—can't wait to see them in person in a couple weeks. Photos borrowed from JP Hodnett. #FossilFriday

What went wrong at the Academy of Natural Sciences? Former staffers point to years of missteps
“There was a big push to not be known as the dinosaur museum,” said one laid-off worker. That shift came with a cost, ex-staffers say.

drexel wants you to think the academy closed because of declining attendance. And yet, they purposefully wanted to push themselves away from being the "dinosaur museum" in philadelphia, and cut programs like the live animal exhibits to appeal to adults......

Attention Philly Families! It is critical that we show Drexel and city government that our enthusiasm for the Academy of Natural Sciences is going strong! Bring your kids, friends, & neighbors down to the parkway on Saturday from 2-6pm. It's a kid-friendly rally to support the academy!
dinosaurs and bugs happily party together at the Save the Academy family rally. Saturday September 26, 2-6pm 1900 ben Franklin parkway, come dressed as your favorite dinosaur, insect, animal, or just yourself! There's a duck billed dino, a triceratops, a brachiosaurus, a pterodactyl, a millipede, dragonfly, and beetle!

Sauropods: An Artistic History in Four Parts (Art by Charles Knight, Bill Berry, John Gurche, and @tessasaurus.bsky.social)
A group of wriggly-necked, blunt-skulled Brontosaurus wade in a lake while one emerges on the shore, dragging its lengthy tail behind it. A Stegosaurus approaches the lake, dwarfed by the long-necked herbivores.A towering Brachiosaurus with a drooping tail hauls itself out of the water, moving in a wide-legged waddle as rivulets of water drip down its hide. An impossibly tall, earthy-brown Barosaurus with elephantine skin rears high in the air, threatening to crush an encroaching Allosaurus. A young Barosaurus hides behind its tree-trunk legs, crouching in fearful trepidation. A dense conifer forest and gorgeous cloudscape extend behind.A low view of a colossal rearing titanosaur. Its heaving bulk produces a cloud of dusty sand as it lifts upward, revealing the complex array of scales covering its underside and limbs. A little feathered theropod looks on, looking comically tiny beneath the great mass of the colossus before it.

It's embarrassing that universities rather punish pregnant women than serial harassers. Information about notorious individuals goes through the grapevine, so if you're an early career, you learn about these transgressions the hard way.

Life Saving Tip: If people go out of their way to warn you against a lab. Listen. Numerous people can't independently make up the same story. What happened to them WILL happen to you. The university won't protect you. "I can stand my ground" You can't. Your reputation & mental health aren't worth it

The reconstructed skull from Benjamin Waterhouse Hawkins' mount of Hadrosaurus (1868), formerly displayed at the Academy of Natural Sciences of Philadelphia. Photo from my last visit to ANSP in 2021. #FossilFriday
Large plaster skull with a vaguely iguana-like appearance. The jaw is placed separately on a shelf with the rest of the cranium. They are both painted a shade of greenish-gray.

Not a huge surprise (having followed this saga for awhile), but still very disappointing. TLDR (as I understand it) - the Academy is closing its exhibits to the public. It seems like research/collections are still going, but even so the situation is grim.
