Leonardian

views updated

Leonardian A series in the Lower Permian of N. America, underlain by the Wolfcampian, overlain by the Guadalupian, and roughly contemporaneous with the Artinskian and Kungurian Stages. In some areas it is zoned by the use of fusilined foraminiferids. It is the N. American equivalent of the Rotliegende. Redbed localities of Wolfcampian—Leonardian age in Texas and Colorado have yielded many vertebrate fossils.
