Mesozoic An era in geologic history that contained three related periods which became renowned for their large reptiles: the Triassic (which spanned from 251 to 199.6 million years ago), the Jurassic (which spanned from 199.6 to 145.5 million years ago), and the Cretaceous (which spanned from 145.5 to 65.5 million years ago). sedimentary strata where the older underlying layers are tilted and the erosional surface is irregular. • Disconformity: Unconformity between parallel layers of sedimentary rock which is recognizable due to an irregular erosional surface. • Nonconformity: An irregular erosional surface between strata and younger igneous or metamorphic rock. The ten strata systems that geologists use (Cambrian, Ordovician, Silurian, Devonian, Carboniferous, Permian, Triassic, Jurassic, Cretaceous, and Tertiary) compose the "standard geologic column" and are claimed by many to contain the major proof of evolutionary theory.
