Microfossils from the Flechado Formation (Pennsylvanian, Desmoinesian) near Talpa, New Mexico
— Kenneth K. Kietzke
Abstract:
The Flechado Formation near Taos, New Mexico contains a marine microfauna with many elements previously unreported from New Mexico. This microfauna includes 14 species of foraminifers, 15 species of ostracods, spirorbid worm tubes, as well as parts of holothurians, ophiuroids, echinoids, a micro-crinoid and several vertebrate ichthyoliths. The fauna is consistent with the Desmoinesian age as determined from other fossil evidence. The environment is thought to be nearshore, normal marine possibly with a macroalgae flora as evidenced by large numbers of attached organisms without obvious attachment sites preserved.
