Morning,
Nice little collection there. You have a very wide spread on dates. You are correct the small 'triangular' shaped point is a San Patrice....a variant I see quite often in NW Louisiana. Normally they are small and sometimes beveled on the sides. The base on many appear like a moustache and are closely kin to the Dalton Hemphill only smaller. The smaller 'bird points' range from a possible cuney or catahoula or even a homan....the small points are sometimes so generic its hard to distinguish them. Where you found those you should be able to find daltons, bassets or even an evans or two. Should also be some pottery associated with the smaller points. Excellent site!!
