Murrah Cave is one of a series of cave and rockshelters in the Lower Pecos Canyonlands (far eastern Trans-Pecos) that contain evidence of late Quaternary cultures, fauna, and flora. Excavated in 1937, many faunal and floral specimens from Murrah Cave remain undescribed. Among those materials are a coracoid of a Pied-billed Grebe (Podilymbus podiceps), seeds, and charcoal. The major cultural occupation now is dated between 1000 and 600 14C yr B.P. based on textiles. Charcoal dates, however, cluster earlier at around 2500 14C yr B.P. with one date at 4800 14C yr B.P. The Pied-billed Grebe represents the first occurrence in the Quaternary fossil record for the Trans-Pecos. The floral taxa are found in the Trans-Pecos Canyonlands today, part of the Chihuahuan Desert vegetation community, with some being the first known presence in the Lower Pecos Canyonlands. Two short-term mesic periods begin around 2500 14C yr B.P. and 700 14C yr B.P. denoted by the return of modern bison and expansion of the grasslands. These brief periods of increased moisture do not fundamentally alter the desert vegetation community. The floral and avian records highlight the potential available data within and the usefulness of old collections in contributing to modern studies. Full article
