Hello all. A decade ago, before I started keeping proper track of the specimens I own, I purchased a partial femur specimen (for context, it was fairly cheap, less than $150 I think). Anyway, I 'think' that it was from a Hadrosaur, but I don't think the seller knew for sure -- and I know for sure that I don't know for sure! Anyway, I don't recall the formation (I'm going to guess Judith River, but that's based on very little).
Any, if anyone is able to readily identify/confirm that the partial femur is from a hadrosaur, or from something else, I'd deeply appreciate it. The specimen is highly mineralized and heavy; please see photos. Thanks!
