The Common Thresher Age - Miocene Commonality - Uncommon
The common thresher Alopias latidens is almost indistinguishable from today’s modern day
thresher Alopias vulpinus. These teeth average a
little less than
1/2 inch ( 7 mm ) in size. The crown is
triangular with a cutting edge that extends onto the shoulder of
the root where just a hint of
vestigial cusplets may be present. The
roots are distinctive, a heavy “U” shape with no nutrient groove. These
teeth are pretty good at finding their way thru the standard 1/4 mesh
screening.
Small insipid cusplets are not uncommon.
