Hi RW, nice birdies! we are getting all these types out of our cave dig except for the Toyah. What I see in your photo are (Top row next to George W.) is a Fresno (serrated) and Scallorn. Second row (left to right) is Figueroa,Figueroa,Scallorn,Toyah,Scallorn,and Scallorn. 3rd or last row is Figueroa,Ensor,Scallorn,Morris, and Scallorn. As you have several Scallorns, note it's basal variations, but the similarity of corner notching position and angle (is key).
