jikohr Posted October 11, 2022 Share Posted October 11, 2022 Hi everyone! I have my eye on a very interesting fossils from the Hell Creek of Powder River County Montana and both the seller and I am not really sure what this is. It appears to be a vertebra of sort with a large bump in the middle. It measures 5.75 x 3.25 x 2.85/2.2 inches for the centrums (14.6 x 8.255 x 7.24/5.588 cm). To me, it looks like two Struthi caudals that were fused together either from an injury or some sort of disease like cancer. It could also be one large pathological vertebra. Do dinosaurs have fused sacral vertebrae? If yes it could be that. Or it could be something else I didn't even think of. Any insight is greatly appreciated as always! 1 Link to comment Share on other sites More sharing options...

Can any Theropods be ruled out in your opinion? Link to comment Share on other sites More sharing options...
Troodon Posted October 11, 2022 Share Posted October 11, 2022 Probably, because of size you would rule out the smaller theropods and Tyrannosaurids. Best I can do with Struthie 2 Link to comment Share on other sites More sharing options...
