dc.description.abstract "The Sierra Diablo Mountains of western Texas contain an excellent section of Permian rocks ranging in age from Wolfcampian to Guadalupian, which in conjunction with the Permian sequence in the near-by Guadalupe Mountains form the standard section of the North American Permian. Outcrops of Leonardian rocks (Bone Spring formation), poorly exposed in the Guadalupe Mountains, are well exposed in the Sierra Diablo, with excellent three-dimensional control over the complex facies changes which take place at the margin of the Delaware Basin. The sea of early Bone Spring time transgressed an erosion surface of Wolfcampian and older rocks, leaving deposits which reveal many of the environmental conditions. Sediments deposited in the deeper waters of the Delaware Basin, and occasionally on the rim of the marginal shelf, are dark, platy carbonates representing an environment inimical to most forms of life. Immediately behind the transgressing shore line followed an environment of high organic activity. From these deposits large collections of silicified fossils have been obtained. The excellent preservation and ease of recovery of these fossils have permitted much more complete sampling of the fauna than had previously been possible. The nature of the material and its occurrence are such that many inferences may be made concerning the life requirements of the animals represented. The fauna is composed largely of brachiopods, a systematic study of which constitutes most of this contribution. This study has resulted in the recognition of 54 species, 36 of which are new, distributed among 45 genera, 12 of which are new. These 45 genera are distributed among 14 subfamilies, of which six are new, and among 15 families, of which four are new"--P. 263. en_US

This item appears in the following Collection(s)

  • Bulletin of the American Museum of Natural History
    The Bulletin, published continuously since 1881, consists of longer monographic volumes in the field of natural sciences relating to zoology, paleontology, and geology. Current numbers are published at irregular intervals. The Bulletin was originally a place to publish short papers, while longer works appeared in the Memoirs. However, in the 1920s, the Memoirs ceased and the Bulletin series began publishing longer papers. A new series, the Novitates , published short papers describing new forms.
