Troodon Posted May 22, 2020 Share Posted May 22, 2020 Over twenty years of work on the Hanson Ranch Bonebed in the Lance Formation of eastern Wyoming has yielded over 13,000 individual elements primarily of the hadrosaur Edmontosaurus annectens. Findings are presented in this paper. https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0233182 9 Link to comment Share on other sites More sharing options...

Haravex Posted May 22, 2020 Share Posted May 22, 2020 so what happened here? my first thought is to something similar to the zebra and wildebeest crossings of crocodile infested rivers? Any input from someone who has dug in the hell creek might be able to provide some enlightenment. Link to comment Share on other sites More sharing options...
Haravex Posted May 22, 2020 Share Posted May 22, 2020 Also another thing I feel like most of the bones are pointing either northeast or west north 1 Link to comment Share on other sites More sharing options...

My bet is the same type of event occurred here. 1 Link to comment Share on other sites More sharing options...

Any input from someone who has dug in the hell creek might be able to provide some enlightenment. Check out the Depositional Model portion of the paper. Your idea has been suggested for other monospecific bonebeds. The problem with it concerning this bonebed (and others that I know of) is that if this were the case, there would be a pile of articulated or semi-articulated animals. This quarry is all disarticlated suggesting something more is going on. For example: The animals first died in some flood or other catastrophe, then decomposed and then another flood moved them all to the place where they were found. 1 Link to comment Share on other sites More sharing options...
