What Does the Bone Look Like?
While out on the last fossiling trip of 2025 in the Horseshoe Canyon Formation, we came across this really long bone. Anything this big is usually the leg bone of a hadrosaur but it was curved way to sharply for that. From the picture it looks like it could be a rib but right under the top layer of rock, it seems to be bone extended outward from there. However this is just a guess since we can't dig to actually see if it is or not.
Hadrosaur (Hypacrosaurus altispinus) with ilium highlighted in green. (The exact species that the ilium belongs to isn't known H. altispinus is only being used as an example)
So What Actually is This Bone?
After a trip to the University of Alberta's open house, I was able to see a pretty well complete hadrosaur skeleton. It seems like it could possibly be part of a pelvis, specifically the ilium of a hadrosaur but this is just a guess based on similar shaped bones. Further study is needed but as of now that's the best guess.
