"The Hueco Mountain Magdalena gastropod fauna is important because it is the only known, diverse Pennsylvanian marine fauna occurring in limestones within the continental United States. This faunal element has some ecological continuity with the Permian sequences above it and is unique in having four terrestrial species not previously known to occur in marine sequences. A mixture of land and marine snails has never been observed before in the Paleozoic fossil record. The most common faunal elements in addition to the gastropods include hexactinellid sponges, crinoids, and several types of Foraminifera indicating an offshore environment, and this formation is, in fact, near the eastern margin of the Paleozoic Orogrande basin. The fauna is silicified so that recovery of all ontogenetic stages was possible along with many statistically significant population samples. The following are new species: Apachella powwowensis, Ferganospira acteonina, Borestus magdalenensis, Borestus texanus, Glyptospira quadriserrata, Trachydomia turbonitella, and Stegocoelia (Donaldospira) nodosa"--P. [1].
