#FossilFriday #dinosaur eggs & babies from #EggMountain, Late Cretaceous (76 mya) Two Medicine Formation!

Late #FossilFriday! #EggMountain Fossil Egg!

A hand holds a fossilized dinosaur egg with a cracked, textured surface. The grayish-black egg shows detailed preservation of its shell pattern and is displayed against a blurred background of an exhibit.

Happy #FossilFriday! This is one of the first complete #dinosaur #eggs discovered in North America! It is one of many eggs found in the #Cretaceous Two Medicine Formation of #Montana at #EggMountain, a site that preserves dinosaur eggs and bones, ancient lizards, mammals, & more.

Montana dinosaur nesting grounds named International Geoheritage Site For much of the 20th century, dinosaurs had been thought of as lumbering, lizard-like animals. The surprising findings at Egg Mountain suggested dinosaurs were more dynamic and social than previously

Don't get in the field as much as I used to. I "snuck" out w/#MORPaleo in June for prospecting the Late Cretaceous #TwoMedicineFormation #EggMountain. Lots o #Maiasaura bones weathering out & tons of eggshell! I found a nice #coprolite I nicknamed #PoopyMacdougal proudly showed it to Dr. Karen Chin!
