Published online by Cambridge University Press: 14 July 2015
Abstract
The oligopygoid echinoid Haimea bajasurensis n. sp. is described from middle lower Eocene (”Capay Stage”) shallow-marine sandstones in the middle part of the Bateque Formation and shallow-marine limestones in the upper part of the Tepetate Formation, Baja California Sur, Mexico. The new species is both the earliest and the westernmost oligopygoid, and the first occurrence of Haimea in North America.
