Stratigraphy, Paleontology and Correlation of Lower Cretaceous Exposures in Southeastern New Mexico Barry S
New Mexico Geological Society Downloaded from: http://nmgs.nmt.edu/publications/guidebooks/44 Stratigraphy, paleontology and correlation of lower Cretaceous exposures in southeastern New Mexico Barry S. Kues and Spencer G. Lucas, 1993, pp. 245-260 in: Carlsbad Region (New Mexico and West Texas), Love, D. W.; Hawley, J. W.; Kues, B. S.; Austin, G. S.; Lucas, S. G.; [eds.], New Mexico Geological Society 44th Annual Fall Field Conference Guidebook, 357 p. This is one of many related papers that were included in the 1993 NMGS Fall Field Conference Guidebook. Annual NMGS Fall Field Conference Guidebooks Every fall since 1950, the New Mexico Geological Society (NMGS) has held an annual Fall Field Conference that explores some region of New Mexico (or surrounding states). Always well attended, these conferences provide a guidebook to participants. Besides detailed road logs, the guidebooks contain many well written, edited, and peer-reviewed geoscience papers. These books have set the national standard for geologic guidebooks and are an essential geologic reference for anyone working in or around New Mexico. Free Downloads NMGS has decided to make peer-reviewed papers from our Fall Field Conference guidebooks available for free download. Non-members will have access to guidebook papers two years after publication. Members have access to all papers. This is in keeping with our mission of promoting interest, research, and cooperation regarding geology in New Mexico. However, guidebook sales represent a significant proportion of our operating budget. Therefore, only research papers are available for download. Road logs, mini-papers, maps, stratigraphic charts, and other selected content are available only in the printed guidebooks. -
First Occurrence of a Gigantic Pliosaurid Plesiosaur in The
Bull. Soc. géol. Fr., 2003, t. 174, no 3, pp. 271-278 First occurrence of a gigantic pliosaurid plesiosaur in the late Jurassic (Kimmeridgian) of Mexico MARIE-CÉLINE BUCHY1,EBERHARD FREY2,WOLFGANG STINNESBECK1 &JOSÉ GUADALUPE LÓPEZ-OLIVA3 Key words. – Kimmeridgian, Pliosauridae, Mexico, Palaeobiogeography. Abstract. – Reinvestigation of a partial vertebral column from the Kimmeridgian La Caja Formation of Mexico, housed in the University of Linares (Mexico), and previously attributed to a dinosaur, proves to be from a very large pliosaurid plesiosaur. This specimen represents the first plesiosaur described from the Jurassic of Mexico. Its length has been esti- mated at 15 metres and, as a juvenile, is considered to be one of the largest Jurassic marine reptiles. The remains of this animal are here described. The morphology of the vertebral column is not diagnostic beyond family level. Large pliosaur vertebrae of a similar size are known from the Upper Jurassic of Europe, and are often referred to the genera Liopleurodon or Simolestes but these identifications are based only upon the size of the centra and have no taxonomic justification. A portion of rostrum with teeth was discovered together with the vertebral column but is unfortunately now lost. The Mexican pliosaur fills geographical and chronological gaps between western Tethys and South American pliosaurs, and is an additional support to the hypothesis of a Hispanic corridor linking at least temporarily the NW Euro- pean marine province with the western South American marine (Pacific) realm during the late Jurassic.

Because of the preoccupation of the people of Texas with petroleum production, many have overlooked the fact that them have been several important metal mines tn this province and that talc deposi ts are s ti1 l being worked here. Undoubtedly othep economic mineral deposits exist in the region awai ting discovery by intensive geological prospecting. The af'fi cers of the El Paso Geological Society and the field trip leadek hope that this trip will heighten inteest in the finding and developing of mineral deposi ts in Trans Pecos Texas. We welcome all our visitcs~sand know that they will wish to jodn us in thanking all those who made thds trip possible. We wish especially to acknowledge the kindness of the Pioneer Talc Company in showing us through the mill at Allamore and allowlng the group to visdt the Texsla- Talc mine. We also wish to thank Mr. Sandy Neal of Van Haon for per- mission to cross the Neal Ranch on the way to the Hazel Wne. John M.

[email protected] ABSTRACT – IGM 9026 is a singular fossil collected at the beginning of the 20th century in an improperly documented site within the Tlaxiaco Basin, near to Tlaxiaco town, Oaxaca, Mexico. The age of the site was suggested as being early Cretaceous. This specimen is the holotype of Plesiosaurus (Polypticodon) mexicanus, which later was identified as a possible late Jurassic marine crocodylomorph of the family Metriorhynchidae, and consequently it was referred as ?Cricosaurus mexicanus. The present study provides a re-description of this fossil based on a microscopic analysis and the use of white and UV lights; these analyses led to the discovery of peculiar dental characters diagnostic of the genus Torvoneustes. This finding supports the re-classification of IGM 9026 under a new nominal combination asTorvoneustes mexicanus. -

Upper Jurassic (Lower Kimmeridgian-Olvido) Carbonate Strata from the La Popa Basin Diapirs, NE Mexico

Las Cruces, New Mexico 88003, United States of America * [email protected] Abstract Carbonate strata that occur as blocks encased in gypsum of three different salt diapirs in La Popa Basin contain a single invertebrate fauna indicating a Late Jurassic (Kimmeridgian) age for all sampled fossiliferous blocks. The most biostratigraphically significant species, present in all diapirs, is the gryphaeid oyster Nanogyra virgula. Other species identified in the blocks include the bivalves Astarte gracilicostula, Cercomya durangensis, Myophorella sp., Grammatodon sp. and the nautiloid Cymatoceras? sp. Geologic relations of the entire assemblage of carbonate blocks, including nodular gypsum interbedded with the fossiliferous beds, salt casts in micrite of the blocks, random structural position of blocks within the diapiric evaporite, absence of blocks younger than Early Kimmeridgian in the diapirs, and regional stratigraphic relations, suggest that the carbonate strata were originally interbedded with, or directly overlie, evaporite strata. This inference is corroborated by the presence of Nanogyra virgula (previously reported as Exogyra cf. E. susplicifera) in carbonate strata directly overlying massive gypsum at Potrero Minas Viejas, adjacent to La Popa Basin. -

The purpose of this work is twofold; fi rst we studied whether the deformation involves or not the basement along crustal faults (thin- or thick- skinned deformation), and second, we studied the nature of the principal shortening directions in the Chihuahua Trough. In this region, style of deformation changes from motion on moderate to low angle thrust and reverse faults within the interior of the basin to basement involved reverse faulting on the adjacent platform. Shortening directions estimated from the geometry of folds and faults and inversion of fault slip data indicate that both basement involved structures and faults within the basin record a similar Laramide deformation style. Map scale relationships indicate that motion on high angle basement involved thrusts post dates low angle thrusting. This is consistent with the two sets of faults forming during a single progressive deformation with in - sequence - thrusting migrating out of the basin onto the platform.
