Happy #FossilFriday! International Beaver Day is April 7, so check out this lovely incisor of the giant #beaver from Freeborn County, #Minnesota! It’s the southernmost record from the state, found on a farm when digging a sump pit in 1958. From the vault at the Science Museum of Minnesota!
#FossilFriday "Sometimes, what arrives at the museum is just a bag of bone fragments." Dr. Alton Dooley dives into the recent bone fragments he & his team has been working on.

I haven't post anything for #FossilFriday in a while but this week while visiting the Field Museum collections I finally got the chance to see the holotype of Thylacosmilus 😍
Join me in celebrating the first #FossilFriday of #JazzAppreciationMonth with this masterpiece of paleo-themed post-bop by the great Charles Mingus.

It’s the age of the dinosaurs, which is why we’re talking about…a fish??? 🐟
Wanna learn more? Head to bit.ly/triassic-fish & tune in next week for another #FossilFriday feature from the Paleo Research Institution’s collection

Whole and partial femur at the Melrose Area Museum. Each bone preserves data from ancient animals that once roamed the area’s post glacial landscapes.

Bones discovered near Hansen Park in New Brighton Minnestoa
#FossilFriday The largest bone in the skeleton—the femur—often survives the test of time. It is the eighth most common vertebrate mammal post cranial element I’ve documented in county museum collections across the Midwest so far.

Possible lower right side premolar (P2) of a Pleistocene Horse.
Possible lower right side premolar (P2) of a Pleistocene Horse.
What I think is the lower right side premolar (P2) of a Pleistocene Horse. Bought from a dealer table at a rock show 10+ yrs ago. No info on it (assuming it’s from Peace River), I just thought it was neat that I could see the structure inside. #fossilfriday

Happy #FossilFriday! This week Dr. Cary Woodruff is visiting #MOR to study the largest animals to walk the Earth, the #sauropods. Here, Woodruff is standing next to the hindlimb of a #Diplodocus (#MOR738) from the #Jurassic #MorrisonFormation of #Wyoming.
Havent been super active this year, so here is a little sketch of Ogresuchus furatus#paleoart

Lobe finned fish decided not to die alone!
Good Friday is a great #FossilFriday for Lazarus taxa! ⚒️🧪
This little mass death assemblage of lobe finned (sarcopterygian) fish comes via the National Museum of Scotland. Devonian, if I recall ... the camera resolution wasn't great. But you can clearly see the lobe fins!
Mastodon skull, with pointy teeth visible. Morrill Hall, Lincoln Nebraska
Happy #FossilFriday everyone! Throwback to one of my favorite mastodon fossils at Morrill Hall. Look at those choppers! 🦣✨
The articulated skull of a huge specimen of the sauropod Camarasaurus—the Gunma Museum specimen (GMNH-PV 101)—sits on a table surrounded by the disarticulated cast bones of the same specimen, arranged roughly in position for comparison. Also, nearby at left is the skull of the Carnegie Museum specimen of a juvenile Camarasaurus (CM 11338). OHIO freshman Klazina McKeigan set this up to help her learn dinosaur skulls. A bunch of theropods skulls also share the table space.
A quiet #FossilFriday in the lab, just me & the gang. Here's the Camarasaurus "station" that @ohiouniversity.bsky.social freshman Klazina McKeigan set up to learn dinosaur skulls: huge skull of the Gunma Camarasaurus (GMNH-PV 101)—both articulated & disarticulated—along with "baby Cam" (CM 11338). 🦕
Another cystoid, but this one is from the Ordovician Bromide Fm. near Criner Hills, Oklahoma.
This specimen of Praepleurocystites watkinsi has some of the column preserved.
#FossilFriday
Another cystoid from a locality I may never get to collect. This is Eucystis angelini from the Ordovician Boda Lm. near Osmundsberg, Sweden.
#FossilFriday
This is a cystoid, another strange echinoderm. It has distinct plates, but not quite the symmetry of crinoids or sand dollars.
This specimen is Erinocystis sculpta from the lower Ordovician near the Wolchow river of Russia.
#FossilFriday
This is another carpoid, but from the Devonian Hunsruck slate of Germany. Rhenocystis latipedunculata is easier to see the plate structure. It also doesn't have 5 point symmetry like most echinoderms.
#FossilFriday
This is a marker sketch I did of the same carpoid. There are distinct plates like other echinoderms, but it is asymmetric.
#FossilFriday
Carpoids are strange echinoderms related to starfish and sand dollars. They don't have the typical 5 point symmetry seen in most echinoderms.
This is Corhurnocystis elizae from the Ordovician Fezouata formation of Morocco.
#FossilFriday
I'm gonna post some strange echinoderms from my collection.
Get ready for #FossilFriday
Have to post this again for Good #FossilFriday, as sis made me see the Easter Bunny in this!
Plus a small reminder that in the end it's science that counts...
Here on #FossilFriday, I offer possibly the most beautiful mosasaur skull ever found, the holotype skull of Plotosaurus bennisoni, a high derived mosasaurine with an akinetic skull, from California, discovered in 1937.
This weeks #Lego #FossilFriday is #Kaatedocus
In 1934, a team headed by Barnum Brown, from the American Museum of Natural History, uncovered about 3000 sauropod bones.
In the 1940s, a fire at the AMNH destroyed most of the collected specimens.
