#FossilFriday brings canoodling Seymouria, a largely terrestrial Permian tetrapod thought to be a stem amphibian. This replica is from our collection, but the original is apparently at Carnegie. They're called the Tambach lovers, although Seymouria aggregations have been found elsewhere too. 🧪⚒️

Replica cast of two canoodling Seymouria sanjuanensis, early Permian, Germany.

Huh, didn’t notice the donor until just now. Guess the original's at Carnegie!

Welcome back to another #fossilfriday I take a break from the Invertebrates to show you this! This is a tooth from a theropod dinosaur likely belonging to an unidentified Abelisaurid. This was found in the Upper Cretaceous (Cenomanian) Dekkar Formation in Morocco.

Welcome back to another #mineralmonday Here is a cut and polished slab of Banded Fluorite from China. Fluorite can form in hydrothermal veins that carry large amounts of calcium and fluorine. Those veins find open spaces in rocks and eventually cool and crystallize.

This is a nearly complete skeleton of the Mosasaur Clidastes from the Late Cretaceous (Lower Campanian) Mooreville Chalk Formation. This was collected in Green County, Alabama around 2007. It is now on display at the Alabama Museum of Natural History in Tuscaloosa.

About 20 years after Benjamin Waterhouse Hawkins made the original Hadrosaurus mount for the Academy of Natural Sciences, three* plaster casts were produced for other museums: The US National Museum, the Field Columbian Museum, and the Princeton Museum of Geology.

Side view of godzilla-posed dinosaur skeleton with round iguana-like head. Standing on a wood base in an open display.

Very similar skeleton in a room with megalodon jaws and Megaloceros and Uintatherium skeletons.

Crowded museum hall with central display featuring Hadrosaurus cast, Megatherium cast, tortoise model, and lots of other stuff.

It's 96 degree weather here in Mississippi collecting fossils from the Late Cretaceous (Late Campanian) Demopolis Formation. ~76 million years ago, the black belt region of Mississippi and Alabama was covered in a warm shallow sea teeming with life. The round objects you see around me are oysters!

Cam Muskelly (Explorer of Deep Time ⏰ ⚒️) @cambriancam.bsky.social · 16/09/2026

There are oysters everywhere! The most common oyter at this locality is the classic Exogyra. These were large oysters that dominated the black belt region here in Mississippi and Alabama.

This #FossilFriday I wanted to share a teaser for some work coming out this week on how best to go about retrodeforming our #Ediacaran fossils here in Newfoundland. These are from another new fossil site with a lot of tectonic compression that changes the appearance of the fossils needing retrodef.

This fossil is an example of what is called a "mortality plate" as it contains the remains of several animals that all died around the same time. Trilobites were some of the first animals to evolve an exoskeleton, and as a result fossilize very well compared to other Cambrian creatures.
