Fossilized skulls of Triceratops dinosaurs on display in a museum exhibit, showing their distinct horns and frilled crests.

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.

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.

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

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! 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.

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.

The thick dome of a pachycephalosaur (MOR 11776) with a small scale model of a fleshed-out version of the dinosaur.

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.
