Once upon a time, the Edward's Plateau was the seashore. Next to that seashore, in those prehistoric tide pools and on those ancient shallow sea floors, an infinite number of sea critters thrived and died. Nowadays the best place in Austin to find urchin exoskeletons is just west of Loop 360 on City Park Road off of Ranch Road 2222. Here, road cuts have exposed fossiliferous limestone filled with little remnants of the age-old animals, making it our choice for the No. 1 Austin location to fossilize.
