Red Dirt Fossils

Happy !
Today's fossils are sections of the sail spine (hyper elongate neural spine) from Dimetrodon. The one on the left was found by my son 2 years ago. The one on the right was found this year. Same site, exact same horizon (deposition contact line) about 8 inches apart, both found insitu, going into the wall. Another single segment about a foot farther down at the same level.
Unfortunately, the distal ends are facing into the wall 😒 which makes me think thus may be the last remnants of a skeleton, long eroded away. I may do a small excavation when I can find time to see if any more spines are laying on that contact line.

National Fossil Day is a fun, unofficial (but then so are all these "days") recognized day on the 1st of June every year. Likely born of a blog post with no intention of actually being recognized, but hey... any excuse to celebrate dinos!

What an unforgettable experience speaking at the Dinosaurs of the Hell Creek Museum! The museum showcases decades of discoveries from Hell Creek and beyond, giving visitors a rare glimpse into the Late Cretaceous world. The passion and dedication behind every exhibit is inspiring. If you’re traveling through the Black Hills, I highly recommend making time for a visit. And for those dreaming of uncovering fossils with your own hands, Paleo Adventures is one of the best ways to experience authentic paleontology digs. 🦴🌄
