Mounted Juvenile Sauropod (Diplodocus) Ulna & Radius - Colorado
This is an awesome radius and ulna of the sauropod Diplodocus sp., collected from our partner's quarry on the Morrison Formation in Colorado. The bones have been nicely prepared from the hard rock surrounding them. They come with a custom metal display stand that holds the bones in position.
The bones were found fractured and fragmented within the rock, each of which required crack repair and gap fill restoration. The proximal end of the ulna required the most restoration, with the majority of the restoration in the form of gap fill where the bone crumbled away. Crack repair and glue stabilization continues through the diaphysis of the bone. The cracks with significant gap fill restoration are closest to the distal end of the bone. While the distal end of the ulna is weathered, there is no indication of any repair or restoration.
The radius has the least amount of restoration of the two bones, with most in the form of gap fill in repaired cracks. These repaired cracks are centralized throughout the diaphysis of the bone. The striated appearance of the bone can be attributed to geologic forces that resulted in countless fractures. The proximal and distal ends are weathered and each required crack repair along the same edge.
Measurements:
Ulna - 19.7" long
Radius - 19.2" long
Bones and stand - 22.4" tall
Comes with the pictured custom metal display stand.
Diplodocus skeletal mount at the Carnegie Museum of Natural History.
One of the best-known sauropods, Diplodocus was a very large long-necked quadrupedal animal with a long, whip-like tail. It could reach up to 115 feet in length but had a relatively small skull, and a mouth full of small peg-like teeth.
