Systematics

Two species are known, A. ceratopsis and A. gracilis. Both are distinguished by their cranial proportions, with A. gracilis having a more slender skull than A. ceratopsis.[2][3]

gollark: I mean, both really.
gollark: Assembly or windows?
gollark: calculator ideas:- hardware implementation of a JS engine- gravel/other stack language calculator- thermoelectricity powered calculator (cooler than solar)- binary lambda calculator (only three buttons needed!)- have some sort of symbolic algebra features for purposes- configurable arbitrary-complex-number bases- calculator with switch which enables modular arithmetic- xylochoron-style base infinity output- built-in paint program- virtual reality mode
gollark: Also, windows bad?
gollark: Just buy more brain cells.
