Fossil Plants (Sphenopteridium & Neuropteris) - Kinney Quarry, NM

The Kinney Lagerstätte is a world-famous Late Pennsylvanian fossil quarry located in the Manzanita Mountains of central New Mexico. The quarry is in the Tinajas Member of the Atrasado Formation and has been assigned a middle Missourian (Kasimovian) age of roughly305 million years. Since the first collections were made in the 1960s, the Kinney Quarry has been long appreciated by paleontologists for its exceptional preservation and diverse assemblage of fossil vertebrates, invertebrates, and plants. The New Mexico Museum of Natural History and Science, Smithsonian Institution, University of Kansas, Carnegie Museum of Natural History, Cleveland Museum of Natural History, and the Sam Noble Oklahoma Museum of Natural History have extensive collections of Kinney material. Due to the high scientific value of Kinney fossils and restricted quarry access, a very limited number of fossils from the site have ever become available for sale on the commercial market.
