During the Triassic Period, 220 million years ago, continental plates began to move apart and rip holes in the Earth's crust. A large lake formed in the fissure that stretched from what today is modern Morrisville to Chapel Hill. Over time, the lake's sediments gradually formed sedimentary rocks and soil that retained large amounts of water. The poor soil plagued Morrisville's development into the 1980s, when public sewer lines were built in the community. Aetosaurus lived 210 million years ago in what would become western Wake County.
