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.

It is about time, #FossilFriday that I promoted Christa Sadler's wonderful book on the globally unique Lower Cretaceous of eastern Utah again. Someday, I hope it leads to a Dawn of the Cretaceous Fossil Beds Nat. Monu. managed like John Day Fossil Beds NM in Oregon. this-earth.com/dinosaur-fro...

This is why we fund scientists to study things like oyster slobber even if you don’t think it sounds important

⚠️ Chinese researchers have invented bone glue that mimics how oysters stick to surfaces underwater.

The adhesive can reportedly repair orthopedic fractures in 2-3 minutes, even in blood-rich environments, and is bioabsorbable.

I have always prided myself in organizing as inexpensive conferences as possible. Our 13th Int'l Mesozoic Terrestrial Ecosystems and Biota Conference a couple of years ago was $280 at door and much cheaper for early birds. Color extended abstract v., t-shirt, & water bottle included.
