Jaleesa Buchwitz , Hunter Carter and I had a great day salvaging pterosaur tracks from the Late Jurassic Salt Wash Mbr., Morrison Fm. @Escalente Petrified Forest State Park. The track slab will be prepared @St George Dinosaur Discovery Site and eventually exhibited at the museum in Escalente.

Just got finished printing this life-sized lungfish model as a gift for the St. George Dinosaur Discovery Site Museum It's a surprise 🤫 so don't tell SGDS Curator @andrewtracks.bsky.social

#FossilFriday from the Substation Quarry at the St. George Dinosaur Discovery Site in SW Utah. Two Anomoepus tracks in a trackway, a nice Grallator, and a theropod vertebra found right at the end of the day.

New theropod tooth today and Handy Excavation is moving in big equipment to get the huge rock pile out of the way. Thanks for all of the amazing support!

Some cool finds today in the Substation Quarry at the St. George Dinosaur Discovery Site! This quarry is becoming massive! We're having lots of fun though.

The St. George Dinosaur Discovery Site is looking for help with funding and crews to excavate an ~1/2 acre of bone beds in the Early #Jurassic (~200 million). We need big excavation equipment. Check out fossils and how you can help in the images attached.

We're looking for help with the excavation of bone beds at the St. George Dinosaur Discovery Site in SW Utah. We need heavy excavation equipment to move a large fossil-rich rock pile and in place rock above the bone beds. The City will break ground for an electrical substation in early April.

Another beautiful phytosaur skull discovered by our SGDS crew in 2020. It's from the lower Church Rock Member of the Chinle Formation from San Juan County, Utah.

For this #FossilFriday, the early #Triassic owenettid Saurodektes kitchingorum from South Africa. This taxon (and other procolophonoids) were some of the only reptilian survivors of the End Permian #Extinction. Was it because they were burrowing? Bonus: There are fossil millipedes (:

Two small fossil reptiles coiled together in what used to be a burrow structure. Only one specimen, towards the top of the photo, preserves the skull

A close up of the fossil reptile skull in lateral view. There’s a tympanic fossa and a large orbit

As we get closer to the weekend, here’s an important reminder, as we aspire for peace of mind via traces. 🐾 (Graphic design courtesy of @stupond.bsky.social)

Here, we describe Uncus dzaugisi from the Ediacaran of South Australia. This vermiform, non-modular bilaterian was curved to sinuous in shape, and moved through the microbial mat with a distinct sinusoidal pattern.

Okay, I'm recycling some cool fossils, etc.from that other social media group that I will soon dump. rare plant fossil from the Late Triassic of SE Utah found in 2023 (manuscript in prep). Androcycas cf. santuccii only known from PEFO! First occurrence in Utah.

My first post @bsky.app. A large semionotid fish called Lophionotus from the Lower Jurassic Moenave Formation on exhibit at the St. George Dinosaur Discovery Site (SGDS) in SW #Utah. We have 100+ specimens at SGDS. Difficult prep because they are encased in iron concretions.
