It's apparently a made-up quote.

Three very delicate bones cleaned in the past 2 days. SUPER RARE - 2 limb bones from a parrot-mimic oviraptorosaur, and the other is a neck bone from a flying pterosaur.

Obviously it's sad when historic #taxidermy cracks, but it can show you how these specimens were converted from flat, treated skins to stand "alive" again. Here, the crack in this rhino at @nhmwien.bsky.social reveals an inner cage of willow beams. 🦏

Bringing up baby: preliminary exploration of the effect of ontogenetic niche partitioning in dinosaurs versus long-term maternal care in mammals in their respective ecosystems Mesozoic dinosaurs and Cenozoic mammals are often regarded as broadly ecologically equivalent, as they included the majority of medium-to-large-bodied terrestrial vertebrates of their respective eras....

I picked up my poster for #2025SVP and it looks SO NICE πŸ₯° I'm very excited! Hope to see you there - my poster session is on the first day (Wednesday) so please stop by, though I know many of us will be distracted by catching up with old friends! πŸ¬πŸ¦–

Black-and-white pencil drawing of a predation scene in the shallow coastal waters of California during the Pliocene. Near a large rock, a mother Herpetocetus morrowi (four-meter-long baleen whale) rests at the surface with her newborn calf balancing on her back. She has just begun to curve downwards in a dive, as a relatively large Homotherium sabertooth-cat is leaping towards her tiny calf with its front paws outstretched. The large cat had been crouched atop the nearby rock. In the distance, a massive cumulus cloud sits just above the surface of the open ocean. On the seafloor below are two small sea urchins, and on the base of the large rock near the seafloor is a Pacific Rock Crab.

On the coast of Pliocene California, a Homotherium pounces upon a newborn Herpetocetus morrowi. These are Cetotheres, small baleen whales that thrived during the Miocene/Pliocene. For the sabertooth, such a tiny calf so close to shore is a rare treat. #paleoart #sciart #pliocene #california

A whale vertebra and taxidermy shrew. The label reads (translated from German):
"Giants and Dwarfs

Mammals have achieved great diversity in form and also they have evolved gigantic forms like whales (the blue whale weighs 130 tons) but also tiny species like the pygmy shrew (4 grams).

Little and large.
I really like this display at @nhmwien.bsky.social showing the size difference between the biggest and smallest #mammals, with a single #whale vertebra alongside a tiny shrew.

Happy #FossilFriday! The teeth of #Tyrannosaurus were a scary sight for all the #dinosaurs in the #Cretaceous #HellCreek ecosystem. Tyrannosaurus bite marks have been found on the bones of #Triceratops, #Edmontosaurus, and even other Tyrannosaurus!

And in that pause between pitch and contact - longer than logic, shorter than hope - we remembered why baseball existed long before we judged a sport's value by viral moments and betting apps. It is the romance of failure. The mortal beauty of trying and missing seven times out of 10 and still being considered great. It is the only sport where patience is a weapon, and panic the surest death. You cannot simply run out the clock in baseball; you must face it, pitch by terrifying pitch, until it finally releases you.

New Fossil Saber-tooth Predator Described from Museum Collection Paleontologists describe new species of sabre-tooth false-cat, showing early evolution of carnivores during time of global climatic instability.

I'm so glad someone excited bought this. It's so beautiful.

Im a long term fan too - I named an extinct sabertooth "cat" after Pangur ban, www.sdnhm.org/blog/blog_de...

We'll close out this #FossilFriday with the obvious choice of Nanotyrannus. I couldn't share this CT scanning session at the time (June 2023) but can now. @jgn-paleo.bsky.social brought the holotype Cleveland skull he had on loan, and CMNH VP curator Caitlin Colleary & I joined in the fun!

A #Halloween #FossilFriday! Here’s a 🧠 brain! Sorta… this is an endocast, where sediment packed into a skull while there was still some soft tissue replacing and molding and casting where the brain was. This particular one is Miocene from Kyrgyzstan and likely horse. Found by @ashpoust.bsky.social
