32.2" Hadrosaur (Edmontosaurus) Fibula on Metal Stand - South Dakota

Hadrosaur (Edmontosaurus) Fibula on Metal Stand - South Dakota #210051

This is a very nice, 32.2" long hadrosaur (Edmontosaurus annectens) fibula bone from the Hell Creek Formation in Harding County, South Dakota. The preservation of this bone is astounding, featuring intact cortical bone and relatively little crack repair or restoration to piece back together. It would have come from the right leg of the the hadrosaur.

On the included stand, this impressive specimen stands 35" tall.

Measurements:
Length - 32.2" long
Proximal width - 4.45" wide
Distal width - 4.2" wide
Height on stand - 35" tall

Very little of this bone has been restored. The majority of restoration can be found in the form of gap fill in cracks where the bone crumbled away or wasn't recoverable. There are repaired cracks through both the diaphysis and epiphyses, though they're fairly minimal in comparison to the majority of bones found in this formation. There are some sections of bone at the proximal and distal ends that are missing.

Hadrosaurs

are frequently referred to as duck-billed dinosaurs and are members of the Ornithischian family Hadrosauridae. They were fairly common herbivores that roamed Asia, Europe, and North America during the Upper Cretaceous Period. Many species of Hadrosaurs had distinctive crests on their heads, some of which had air-filled chambers that may have produced a distinct sound. These crests may have been used for both audio and visual display purposes.

Because of its age and sedimentary composition, the Hell Creek Formation has become one of the most paleontologically studied areas in the world. 158 genera of animals and 64 genera of plants are known from the formation and new discoveries are made frequently. In addition to Tyrannosaurs, Ceratopsids, and Hadrosaurs, the formation has yielded remains of amphibians, reptiles, lizards, snakes and turtles, fish and sharks, avian and non-avian dinosaurs, and mammals. The Hell Creek Formation gives the most complete understanding of the environment just before the Cretaceous-Paleogene extinction.
