We're just a biological speculation
Sittin' here, vibratin'
And we don't know what we're vibratin' about
And the animal instinct in me
Makes me wanna defend me
It makes me want to live when it's time to die

Met with a local landowner this week to organize & outline a manuscript describing the INCREDIBLE variation of Triassic reptile teeth she has been collecting and curating from her property, will be accessioned at @NMMNHS. Check out those compound denticles! #fossilfriday 🦖🧪
