2.35" Nodosaur (Panoplosaurus) Ungal - Two Medicine Formation

 
This is a 2.35" long ungal (claw) of a Nodosaur (Panoplosaurus sp.) from the Two Medicine Formation of Pondera County, Montana. There is a chip of bone missing at the distal end and the proximal is weathered. There is no repair or restoration to this bone.

Panoplosaurus (meaning "completely armoured lizard") is a genus of nodosaurid dinosaur. Panoplosaurus was 5 to 7 metres (16 to 23 ft) long, around 2 metres (6.6 ft) tall. It was heavily armoured, even by the standards of other nodosaurs, probably with traverse bands of studded plates covering its back and tail, although the tail likely lacked the club found in ankylosaurids.



The Two Medicine Formation is a geographical formation in Central Montana and Southern Alberta, Canada. The formation is predominantly sandstone laid down by rivers and deltas during the Campanian Age of the Cretaceous about 80-75 million years ago. Approximately two thousand feet thick on the western edge, it lies on top of the Virgelle Sandstone formation and under the Bearpaw Shale. It is located between the Front Range of the Rocky Mountains and the Sweetgrass Arch, a tectonic fold feature 40-90 miles east of the Front Range.

The Two Medicine is the same age as the Judith River Formation found further east. It was laid down further inland from the Western Interior Seaway, while the Judith River Formation was deposited along the coast. The Two Medicine contains much of the same dinosaur fauna, but fewer reptiles, amphibians and aquatic fossils.
