32.1" Partial Hadrosaur (Edmontosaurus) Fibula - Wyoming

This is a beautiful 32.1" long hadrosaur (Edmontosaurus annectens) partial fibula bone from the Lance (Creek) Formation of Wyoming. The preservation of this bone is astounding, featuring intact cortical bone and only a few small areas of crack repair or restoration to piece back together. It would have likely come from the right leg of the the hadrosaur.

Measurements:
Length - 32.1" long
Proximal width - 6.95" wide
Distal width - 2.55" wide

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 that are missing, and the distal end was not recovered.

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.

The Hell Creek Formation

Renowned for both its age and rich sedimentary layers, the Hell Creek Formation is one of the most intensively studied fossil-bearing regions on Earth. To date, scientists have documented 158 genera of animals and 64 genera of plants from its rocks, with new finds emerging regularly. Beyond iconic dinosaurs such as tyrannosaurs, ceratopsians, and hadrosaurs, the formation has produced an extraordinary array of life, including amphibians, reptiles, lizards, snakes, turtles, fish, sharks, birds, and early mammals. Together, these fossils provide the most complete picture of the ecosystems that thrived just before the Cretaceous–Paleogene extinction event.
