"Pleistocene Soricidae from San Josecito Cave, Nuevo Leon, Mexico" by James S. Findley is a scientific publication authored in the early 1950s. This work primarily focuses on the examination and classification of soricid (shrew) remains found in San Josecito Cave, shedding light on Pleistocene mammalian fauna in Mexico. It serves as an important contribution to the field of paleontology, particularly in understanding the geographical distribution and ecological conditions of ancient species. In this publication, Findley details the discoveries of numerous vertebrate bones from the Pleistocene era, specifically concentrating on the Soricidae family. The author identifies and describes several species, including "Sorex cinereus", "Sorex saussurei", and "Cryptotis mexicana", providing comparative analysis with modern specimens. The findings indicate that the fossilized remains suggest the presence of formerly more humid environmental conditions in the region, expanding the known range of these shrew species significantly. Overall, the work is a significant resource for researchers interested in ancient North American mammals and their ecological contexts. (This is an automatically generated summary.)
