Conkling Cavern is a paleontological and archaeological site located in Doña Ana County, New Mexico. It was excavated in the late 1920s under the direction of Chester Stock. Unfortunately, Stock never published the fossil fauna from the excavations. Instead, R. P. Conkling, who had drawn scientific attention to the site, published very preliminary lists of mammals identified by Stock and birds identified by Howard. Several authors have done research on portions of the recovered fossil fauna. Excavated before modern dating techniques were developed, little is known about the chronology except some apparently is Holocene and much is Pleistocene in age.
