Allosaurus Posted March 31, 2015 Share Posted March 31, 2015 Unfortunately I don't know which state it's from, but it is from the Hell Creek Formation, western USA. It looks like some kind of vertebra, I was thinking maybe a theropod, but not sure. Ideas? Any chance of identifying it down to the species level?

jpc Posted March 31, 2015 Share Posted March 31, 2015 This looks like champsosaur as well. Link to comment Share on other sites More sharing options...
Troodon Posted March 31, 2015 Share Posted March 31, 2015 Yep agree with jpc its a Champ.. Link to comment Share on other sites More sharing options...
Opisthotriton Posted March 31, 2015 Share Posted March 31, 2015 I'm really not seeing the champ-ness. The first photo shows one end is concave, and the whole centrum looks dorsally(?) elongated. I don't see the hourglass that champs have on their dorsal surface. The last photo shows it has a strange outline, looks kind of familiar, but I'm not sure what it is.

jpc Posted March 31, 2015 Share Posted March 31, 2015 allosaurus... we need to get more in-focus pix. The paper towel is more focused than the bone. I am not 100% sure it is champs, but that is my best guess so far. Link to comment Share on other sites More sharing options...
Allosaurus Posted April 1, 2015 Author Share Posted April 1, 2015 Is this better? If not I may have to wait until tomorrow for some better ones. The sunlight is quickly starting to disappear. Link to comment Share on other sites More sharing options...
jpc Posted April 2, 2015 Share Posted April 2, 2015 Much better pix. I will recant my champsosaur ID and call it a mystery bone. Yes, probably some sort of Dino final spinal. Link to comment Share on other sites More sharing options...
