The bedrock in the outcrops formed during the Paleozoic Era, and Coelophysis lived during the Mesozoic Era. The youngest rock layer is from the Permian, and Coelophysis did not exist yet. Coelophysis lived at a much later time. No Triassic bedrock is shown. Layers containing Coelophysis have been removed by erosion. 26. The fossil was found only in the Devonian layer/one layer in each outcrop. The fossil was geographically widespread.
