A new coprolite ichnofauna from the Upper Pennsylvanian (Missourian) Tinajas locality, central New Mexico
J. A. Spielman, A. P. Hunt, S. G. Lucas and A. J. Lerner Pennsylvanian strata in NM are interbedded marine and nonmarine sediments deposited in basins of the ancestral Rocky Mountain orogeny that contain several
Prehistoric travertine pendants from central New Mexico: Potential relationships with known travertines
K. E. Zeigler, L. J. Crossey, L. Schuyler, D. Phillips and K. E. Karlstrom Prehistoric sites in New Mexico have yielded dozens of elongate, banded travertine objects, some of which were perforated for use as
Stratigraphy and sedimentation of the Middle Pennsylvanian Red House Formation, Caballo Mountains, Sierra County, New Mexico
K. Krainer, S. G. Lucas and J. A. Spielman In the Caballo Mountains, we studied several sections of the Atokan Red House Formation, which is the basal unit of the Pennsylvanian section locally. At these
Depositional environments, sediment dispersal, and provenance of the Lower Permian Glorieta Sandstone, central and northern New Mexico
E. M. Bauer1 and G. H. Mack1 1Department of Geological Sciences, New Mexico State University, Las Cruces, NM, 88003 During early Permian time, the region that now encompasses the Colorado Plateau was periodically covered by
Preliminary anisotropy of magnetic susceptibility (AMS) and paleomagnetic data from mafic dikes in the Chili quadrangle, Rio Arriba County, New Mexico
R. Trujillo, M. S. Petronis1 and J. Lindline Migration of magma at shallow levels of the crust is a fundamental process that has bearing on the construction of volcanoes, the associated hazards in active volcanic
Structural anisotropy of magnetic susceptibility (AMS), and paleomagnetic investigations of a steeply dipping, welded tuff (Amalia tuff) south of Petaca, New Mexico
L. Garcia, M. S. Petronis and D. Koning The Elk and West Elk Mountains of southwest Colorado are dotted with Mid-Cenozoic plutons that can provide important geochronological and thermochronological data about the transitional interval between
Early Paleocene (Torrejonian) ant-hill vertebrate assemblages from the Nacimiento Formation, New Mexico
T. E. Williamson and U. L. Denetclaw Paleontologists have long taken advantage of the harvester ant’s habit of armoring their nest mounds (ant-hills) with small pebbles and other objects gathered from the surrounding landscape. Ants
