Great new paper by Mannion & Moore 2025 on diplodocoid sauropods for #FossilFriday I love their latest phylogeny as it certainly supports the mass extinction of sauropods at the end of the Jurassic that is so well documented in eastern Utah. www.tandfonline.com/doi/epdf/10....

Had the amazing privilege earlier in the year to watch a lithographic limestone plate be made by one last plate makers in Germany. Each plate is cut and then hammered by hand into shape - and after having a go it's very skilled work. Currently they have no apprentices, so a truly dying art.

So yesterday a reporter asked Donald Trump about the writ of habeas corpus, and he had no idea what it was.

"I don't know," he said. "I'd rather leave that to Kristi."

Well, It turns out Sen. Hassan asked Kristi Noem about it in May, and this was Noem's response:

HASSAN: What is habeas corpus?

NOEM: Habeas corpus is a constitutional right that the president has to be able to remove people from this country

HASSAN: That's incorrect

A newly minted name for Utah's largest dinosaur, Utetitan! Given the amount of time these latest Cret sauropods span, more than one taxon likely. I did not review this manuscript, so let the sauropod researchers weigh in.

The fabulous SGDS is starting a weekend paleoprogram to supplement the great work they are doing in southwestern Utah. Fossil Discoveries offers the unique opportunity to learn, explore, and make real contributions to science. Running until mid Dec. utahdinosaurs.org/fossil-disco...

Actually Sphenoceramus; Utah's Platyceramus cycloides in the Blue Gat Shale might get nearly this big. @utahpaleo-ufop.bsky.social

For #FossilFriday, meet Inoceramus : the largest bivalve to ever exist. This genus lived in the Cretaceous seas of North America and Europe.

This one is 178 cm long. And look at these rings ! It must an amazing palaeoenvironmental recorder to work with 😍

#PaleoSky 🦑 🧪 ⚒️
A shell of a bivalve mollusc that was found in 1952 in the valley Qilakitsoq on the Nuussuaq peninsula in western Greenland.

The scientific name of these bivalves is Inoceramus steenstrupi. They lived between 83 and 63 million years ago. These are the largest bivalves ever to exist. It is thought that they lived in an oxygen-poor environment and that they layed unattached on the sea floor filtering plankton and detritus from the water.

The shell is 178 cm (70 inch) long. The other half of the bivalve is in the Geological Museum of Copenhagen. ___

On display at the Greenland Institute of Natural Resources. Link to this new Institute filled with many hallway displays at www.natur.gl/ hey now, "moi" for scale and a line-up of 2014 Nuuk Geoscience Workshop geologists waiting for their turn with the mighty mollusk.

The Nuuk display is geotagged instead of the Cretaceous fossil-bearing rock formation on the opposite side of Greenland.

Replace "the Cosmos" with "the History of the Earth and its Biological History." To specifically define how paleontologists must operate!

For #FossilFriday, an ichnological 2-for-1 special in a body fossil: a termite nest packed with termite coprolites (feces) in an araucarian tree trunk, from the Early Cretaceous (~125 mya) of Victoria, Australia; oldest termite nest in Australia & largest wood nest from this time. 🧪🪵🪨⚒️ #ichnology
Gray to light brown fossilized (petrified) wood with interconnected spaces between the wood filled with sand-sized coprolites (fossil feces); the spaces are interpreted as a nest, and the coprolites are also attributed to termites. A few black spots on the surface are of modern marine mussels, with a marine snail and barnacle in the upper left, which were living there because the fossil tree was on a rocky marine platform on the coast of Victoria, Australia.

Been to that site (ridiculous number of fossil frogs mixed in with that skeleton) and I have visited that museum in 2013. They have a Gastonia and a Falcarius mount. Nice facility.
