Looks like a pretty good match to my eyes in Clemens, though I can't determine species: "Cusp formula 1 to 4:5 to 7:0 or 1. There are from five to seven cusps (mode = 6) in the medial row; the first is small and low. The following, well-separated cusps are not much higher - measured from the apex of the cusp to the base of the intercusp notch - but the central area of the crown increases in height..." 1 Forever a student of Nature Link to comment Share on other sites More sharing options...
jpc Posted August 13, 2022 Share Posted August 13, 2022 looks like I dropped the ball on this one. Glad you were able to find it. I agree... Mesodma... but it would also be useful to compare the stated size range to yours. 1 Link to comment Share on other sites More sharing options...

I didn't see a table for M. formosa that included P4, only for M. thompsoni: at 3 mm, my tooth compares well Forever a student of Nature Link to comment Share on other sites More sharing options...
