Happy #FossilFriday! While #dinosaurs reigned on land, the rivers of the end-Cretaceous were filled with a variety of organisms, including fishes, turtles, and crocodilians. This is the carapace (upper shell) of a soft-shelled #turtle (#MOR1114) from the #Cretaceous #HellCreekFormation in #Montana.

Next up, here's my take on the bone head of the Late Cretaceous period of Montana, the pachycephalosaurus. I hope you guys like this little fella. #paleoart, #paleontology,#dinosaurs, #scupleyclay, #hellcreekformation.

Happy #FossilFriday! Hundreds of fossils of the horned #dinosaur #Triceratops have been discovered in the #Cretaceous #HellCreekFormation in #Montana. In juveniles like #MOR1199, the #horns above the eyes curve backwards. As Triceratops grew up, the horns curved forward.

Happy #FossilFriday! Pachycephalosaurs are sometimes referred to as the “dome-headed” dinosaurs. This thick dome belongs to a large pachycephalosaur (MOR 11776) that was discovered in the #Cretaceous #HellCreekFormation of #MakoshikaStatePark.

Happy #FossilFriday! This is part of the tail of an #Edmontosaurus (#MOR007) from the Upper #Cretaceous #HellCreekFormation of #Montana. Study of this fossil revealed that show duck billed #dinosaur had a segmented frill along the top of its body.
Fossilized vertebral column and rib bones embedded in a large, triangular slab of rock on display in a museum exhibit case. The specimen appears to be from a prehistoric marine reptile or dinosaur, with visible rib structures extending outward from the central spine.

Happy #FossilFriday! Every day, the #fossils of #dinosaurs & other creatures undergo #preparation for research & display in the #MOR lab. Here MOR Fossil Preparator Cassi Knight conserves the hip bones of a #Triceratops (#MOR799) from the #HellCreekFormation of #Montana.

#MORPaleo was all over the state this year! A month in #TwoMedicineFormation at #EggMountain, several weeks in #BearpawFormation digging up a BIG tylosaur, several weeks in the #KootenaiFormation digging up a big iguanodontid & wrapped at #MakoshikaStatePark #HellCreekFormation finding good stuff!

The MOR #Paleontology Field Crew is back from exploring the #Cretaceous #HellCreek Formation in Makoshika State Park in #Glendive, #Montana. Staff and students uncovered the fossils of ancient plants, #turtles, crocodiles, and #dinosaurs that roamed the region at the end of the Age of #Dinosaurs.

Were some Mosasaurines using river systems as nurseries or just there for some good grub?

Dug up Dinosaurs in #HellCreekFormation today via #Paleoadventures. Most significant finds were a Melvinius Vertabrae, a small lizard Vert, and some Therapod Bones. I also found two Triceratops teeth & a rib I hope I can finish tomorrow. #Dinosaur #Paleontology #BuyMyBook #Dinosaurs #Fossil
Me and my older brother digging up Dino’s On the left is my Therapod Bone, some more still embedded in the rock in that teeny tiny black spot to the bottom right of the bag. Upper left is a Rib potentially, still more to uncover on the right. A Melvinius Vertabrae I forgot to take a picture of after I got it out and gave it to the science team My Dinosaur Horror book I wrote! Turns out when I took this picture I would later discover, JUST BEHIND THIS, a Triceratops tooth and the Therapod bones.

Ich würde ja wirklich gerne in Montana leben, am besten direkt an oder in der Hell Creek Formation. Die Vorstellung, beim Spazierengehen einfach so Dinofossilien zu finden, zu katalogisieren und die wundervolle Natur aufzunehmen, ist zu schön #Montana #HellCreekFormation #Dinosaurier #Fossilien
