Greene projectile point
Greene projectile points are stone projectile points manufactured by Native Americans what is now the northeastern United States generally in the time interval of 300–800 AD.[1]
Greene projectile point from central New York State
Description
Greene points are generally about 2 to 4 inches (5.1 to 10.2 cm) long with an average around 2.5 inches (6.4 cm). They are lanceolate in shape with weak or no shoulders and are 2¼ to 2½ times as long as they are wide.[1]
Age and cultural affiliations
Their first recorded appearance is around 400 AD and vanished around 800 AD with the onset of the Kipp Island phase in central New York.[1]
Distribution
These points are found primarily in the middle Hudson Valley of New York State, but are found as far east as Massachusetts.[1]
gollark: Regular expressions, strictly, can only parse regular languages. I don't know exactly how that's defined, but it may not include your chemical formula notation. It probably can be done using the fancy not-actually-regular expressions most programming languages support, but it might be quite eldritch to make it work right.
gollark: I'm not sure if this is a problem actual regexes (I mean, most programming languages have not-regexes with backreferences and other things) can solve, actually?
gollark: Oh, just formulae, not names? That's much easier!
gollark: And tons of weird special cases which need hardcoding.
gollark: It's probably a Hard Problem™ to parse chemical names generally, though, since there are tons of weird prefixes and suffixes and whatnot.
