It is not often that I make a 2 #FossilFriday posts but, I will make an exception. This is the skeleton of the fish Xiphactinus audax. It was found by a friend looking fossils in the Late Cretaceous (Santonian) Smokey Hill Chalk in Kansas. You think you afraid of the ocean now? You've seen nothing!

Measuring pelvis of new Berriasian (basal Cret) polacanthine, sp. B. Similar to Mymoorapelta in flexing preacetablar end laterally so that the entire lat. margin parallel to sacrum unlike anteriorly diverging ilia of Gastonia. #FossilFriday @utahpaleo-ufop.bsky.social @paleontologizing.bsky.social

Need to describe this tasty, small, but robust latest Cenomanian 93.5 Ma exogyrid oyster from the Pine Valley Mts. of sw Utah. This holotype is in the collections of the Prehistoric Museum, Price along with 10 more. This taxon is unusual in its thick inflated right valve. #FossilFriday

And only one in five die before their first birthday. Them is some good odds.

Jack Horner in the Epstein File trying to raise money to fund dinosaur research. When I discovered we had rich nazis on our dig in 2008, I dropped them like a rancid turd; ask Don. There will never be a Trumpasaurus with my name attached! @paleontologizing.bsky.social @utahpaleo-ufop.bsky.social

#FossilFriday Thinking about mired sauropods vs the western Chinese dino-deathtraps. Type skeleton of the turiasaur Mierasaurus bobyoungi was a mired sauropod. Price River II site includes many upright articulated titanosauromorph feet. @utahpaleo-ufop.bsky.social @prehistoricmuseum.bsky.social

#FossilFriday The ischium bone on the right from #IsleofWight formed part of the iguanodontian dinosaur pelvis. In 1849 the bone was understandably still something of an enigma and here has been misidentified by Gideon Mantell as a clavicle.

Very special #FossilFriday, pleased to announced that we have a new paper out on reconstructing the ecosystem of Dry Mesa Quarry in the Morrison Formation We used modern ecological techniques to quantity and model the ecosystem Feel sorry for the baby Sauropods 😞 🦕🦕 Sergey Krasovskiy +Pedro Salas

“This Is a Warning”: ICE Agents Follow Protesters Home newrepublic.com/post/205759/... via @newrepublic.com

Protesters wanted to draw attention to the detention of a 5-year-old boy from the Minneapolis area at the Texas ICE facility. They were met by state troopers who used pepper spray to disperse the crowd.

I wrote this song on Saturday, recorded it yesterday and released it to you today in response to the state terror being visited on the city of Minneapolis. It’s dedicated to the people of Minneapolis, our innocent immigrant neighbors and in memory of Alex Pretti and Renee Good. Stay free

In 1922, insulin co-discoverer Frederick Banting refused to profit from the discovery and offered it to the world as a global public good. Today, many people with diabetes still don't have access to affordable and quality treatment and care.

#3) One big f-ing stego Sadly, it's only know from partial forelimbs, but we document a stego that based on limb dimension is ~38% longer than the average stego. Assuming we could generally scale isometrically (don't come at me!), that all equals the largest specimen thus far.

A coworker took this from her apartment. I haven't seen a crowd this size before. Maybe the first Women's March? But it was much much warmer that day. ICE OUT OF MINNESOTA!

I heard this live, too! Unbelievable......

A lack of food for penguin chicks in the first weeks of their lives would be fatal. In addition, penguins play a key role in Antarctic food chains; losing species would increase the risk of broad ecosystem collapse: www.theguardian.com/world/2026/j... (gift). #birds 🌎

This is a terrifying concept, as foreign introductions very rarely have good, let alone neutral results.

Instead, the agency is calculating only the costs to companies of complying with pollution regulations. The Trump administration is literally saying they put $0 value on human life. That has implications far beyond the EPA decision: www.nytimes.com/2026/01/21/c... (gift). 🌎
