hoping raptor and triceratops I want to ID before I buy
In SD, that is the Lance Formation though it is geologically the same.
Troodon is still valid, as stated by https://www.nature.com/articles/s41598-018-30085-6
I do agree though that the ceratopsian tooth cannot be given an ID beyond Triceratops sp. as the teeth of each are very similar.
@Sonic0627 Can you get images of the theropod tooth with a scale bar? The size of the tooth, the size of its serrations and such, all are important when trying to ID a tooth.
