late commer here but the i thought i might put my 2 cents worth in, the first point is a jetta, the deep bifurcation without the basal thinning of pedernales coupled with ground outer edges of the "legs" is a classic jetta rework, the next one appears to be one also although worn out, look for an un reworked one they are awsome! hope it helps. ron
Thanks for the reply Sandman. I noticed in Turner/Hester's latest book edition, they dropped the Hare Biface as a type for some reason. Perhaps they now view the Hare Biface as a preform of a type that was never completely finished?
