Pink Pisanosaurus by David Tana
04 - Pisanosaurus mertii - the oldest known ornithischian dinosaur from the Late Triassic (~228 - 216.5 mya). Probably herbivorous and highly cursorial. Based primarily on other known basal ornithischians and heterodontosaurids, with a little "fuzz" a la Tianyulong. Pen and highlighter on paper.
