I bought some Teeth from the man who found them outside Palo Duro Canyon, near Amarillo Texas.
He wasn't sure what they were, so I thought it'd be best to post them here and ask for opinions on them.
and just so you know, he didn't find them on the State park. They are from a ranch that backs up to the canyon. The second and third were in the same layer, and the first was in the layer above the others.
Thank you!
