I am fairly comfortable with the STH micros as far as identification goes but I found a few things that I need some help with.
First up is one that I am 90% sure on the ID but I want to be sure. I believe I found a couple of Raja teeth. The first one I found looks to be complete and tiny, a little over 1mm. I know skate teeth are somewhat uncommon in this fauna and this would be my first one.
