| 释义 |
The Simpson point is a Paleo-Indian projectile point with a wide blade noted for exhibiting a narrowed 'waist' (middle section). It also features a concave base and eared basal corners. It was named in 1962 by Ripley P. Bullen. Points are mostly dated to 9000BC [1] and are considered to be a typical example of the Middle Paleo-Indian subperiod (9000-8500 BC).[2] References1. ^{{Cite book |title=North American Projectile Points | last=Hranicky | first=William J. | year=2010 | edition=revised | publisher=AuthorHouse | isbn=978-1-4520-2632-9 | page=393| url=https://books.google.com/books?id=ctw4OPNR540C&pg=PA393&ved=0CCsQ6AEwAA#v=onepage&q&f=false}} {{Archaeology-stub}}2. ^{{citation | last1=Ward | first1=H.
