Near La Mira, the echinoid occurs in the lower part of the marine beds cropping out around the Ferrotepec iron mines (Sicartsa Mining Company). These beds are of late early to early middle Miocene age and rest unconformably on the ore bearing strata of pre-Cenozoic age (Durham et al., 1981). Download full text.

Resumen
The only Cenozoic fossil echinoid recorded from the Pacific coast to mainland Mexico, between the Guatemalan border and Puerto Vallarta, at the entrance to the Gulf of California, is Encope micropora L. Agassiz (Palmer and Hertlein, 1936, p. 66) from the Pleistocene Colotepec Formation of the southern coast of Oaxaca (Caso, 1951, 1961; Buitrón, 1978). Recently, several Cenozoic marine basins have been discovered along the Pacific Coast (Durham et al., 1981). In two of these basins, one near La Mira, Michoacán, and the other near Santa Cruz, Oaxaca, fossil keyhold urchins (genus Encope) were found. Near La Mira, the echinoid occurs in the lower part of the marine beds cropping out around the Ferrotepec iron mines (Sicartsa Mining Company).
