This is one of many related papers that were included in the 2006 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.

MICHAEL QUEEN1 AND LESLIE A. MELIM2 1814 North Canal Street, Carlsbad, NM, 88220, [email protected] 2Western Illinois University, Dept. of Geology, 1 University Circle, Macomb, IL 61455, [email protected] ABSTRACT.—Biothems are speleothems in which the morphology, internal structure or composition was influenced by organ- isms. This paper is a first attempt to identify biothems found in modern and fossil pools (former pools, now dry) of the Gua- dalupe Mountain caves. We have identified several features that suggest biologic involvement including patchy distribution, projecting forms, downwardly pendant forms, active slime (biofilm), mineralized slime, internal micritic or pelmicritic fabric and fossil filaments and/or fossil biofilm seen in the scanning electron microscope. We distinguish between Type 1 biothems, those containing direct evidence of microbial involvement, and Type 2 biothems, those suspected of biologic involvement but lacking obvious direct evidence. Type 1 biothems include bryolites, conical crusts, moonmilk (some varieties), pool fingers, ramose balls, rusticles, u-loops and webulites. Type 2 biothems include blades/chenille spar, drips, hemispheres, pinnacles/ conical mounds, scales, radiating flowers, tangential chips and tufted cushions. These terms are preliminary and meant to guide future research.

    ZOBODAT - www.zobodat.at Zoologisch-Botanische Datenbank/Zoological-Botanical Database Digitale Literatur/Digital Literature Zeitschrift/Journal: Berichte der Geologischen Bundesanstalt Jahr/Year: 2019 Band/Volume: 132 Autor(en)/Author(s): Nagel Doris, Pacher Martina, Tsoukala Evangelia Artikel/Article: Large mammals except cave-bears from the Loutra Almopias Cave, Late Pleistocene, Macedonia, Greece 123-147 Berichte der Geologischen Bundesanstalt 132 Large mammals except cave-bears from the Loutra Almopias Cave, Late Pleistocene, Macedonia, Greece Doris Nagel 1, Martina Pacher 1 & Evangelia Tsoukala 2 Abstract Excavations in the Loutra Almopias cave yielded a large amount of different vertebrate taxa assigned to two different time horizons. Here we describe the carnivores, with the exception of the cave bear, and herbivores found in the cave. Special focus lies on the mustelids, not evaluated previously, and the comparison of leopard, hyena and chamois. The composition of the mustelids in the isolated chamber Ia confirms its chronological assignment into the Late Glacial, while most of the larger mammals, such as Crocuta, Panthera and Rupicapra, fit into the time before the Last Glacial Maximum (LGM). Zusammenfassung Die Grabungen in der Loutra Almopias Höhle ergaben eine große Anzahl an unterschiedlichen Ver- tebraten, die zwei verschiedenen Zeithorizonten zugeordnet werden. Wir beschreiben hier die Car- nivora, mit Ausnahme des Höhlenbären, und die Herbivoren aus der Höhle. Der Schwerpunkt liegt auf den bis jetzt unbearbeiteten Musteliden, sowie auf dem morphologischen Vergleich der Hyäne, des Leoparden und der Gämse. Die Zusammensetzung der Musteliden aus der isolierten Kammer Ia bestätigt die zeitliche Einstufung in das Spätglazial, während die meisten Großsäuger, wie Crocuta, Panthera und Rupicapra, in die Zeit vor dem letzten Vereisungshöhepunkt im Glazcial (LGM) zu stellen sind.

  • Fossil Cave / Green Waterhole Cave (5L81) Bone Retrieval Dives for Dr Trevor Worthy (University of Adelaide), 27/28 May 2006
    FOSSIL CAVE / GREEN WATERHOLE CAVE (5L81) BONE RETRIEVAL DIVES FOR DR TREVOR WORTHY (UNIVERSITY OF ADELAIDE), 27/28 MAY 2006. PARTY Peter Horne (Team Coordinator), Neville Skinner (underwater photographer/ support & safety Diver), David Albano (support/safety diver) and Mark Nielsen (safety diver); Ian Lewis (surface support). OBJECTIVES To attempt to relocate 1979 Flinders University survey star-dropper posts along the “N” line, especially N3 dropper, and an adjacent labelled tag known as “Aslin Site 12” (“Site 07” during the 1979 project); to attempt to photograph the area before, during and after any bone-digging work; and to collect samples of bones and sediment around Tag 12. Carrying gear down to the cave’s lake which is situated in the dark alcove behind the two scuba cylinders at the far end of the collapse (Peter Horne). The research party (left to right): Neville Skinner, Ian Lewis (surface support), Mark Nielsen, David Albano and the author (Dave Albano/Peter Horne). OUTCOMES Dive One: Saturday 27 May 2006 (duration approx. 45 minutes). Peter and Neville descended first through the “Letterbox” with a large open reel of thick white synthetic rope with the intention of locating and securing the old N3 star-dropper. The water was noticeably dark and murky, suggesting that crushed grass observed around the carpark area was most likely caused by a group of other divers earlier that morning, which was unfortunate from the point of view of photography. The water level was also lower that Peter had ever seen, and there was a substantial air section extending into the normally-flooded ceiling area of the cave.

  • Practice and Prospects in Underwater Palaeontology
    Palaeontologia Electronica palaeo-electronica.org Practice and prospects in underwater palaeontology Julien Louys ABSTRACT Underwater deposits, especially those in phreatic caves, often contain exquisitely preserved fossils, and many represent Quaternary Konservat-Lagerstätten. Neverthe- less, they are unrecognised as such by most practicing palaeontologists. This review highlights the unique contributions to palaeontology made by underwater deposits as well as the technical and practical challenges facing underwater palaeontologists. Recovery of fossils from such deposits requires specialist training, equipment, and pro- cedures unique to these environments. Taphonomic studies of underwater assem- blages are rare and hampered by difficulties in fossil recovery. Neotaphonomic experiments and observations of modern accumulations in underwater settings should be a priority for future research. Regions where such techniques might provide import- ant new insights into Quaternary faunas and environments, not accessible through tra- ditional palaeontological approaches, include low-lying flooded continental shelves and soil-poor karstic landscapes. Underwater palaeontology represents a largely unex- plored yet significant source of fossils, further study of which will expand and enrich tra- ditional approaches in the study of ancient organisms.

In addition to their geological, anthropological and historical interest, the caves are home to a variety of cave-adapted organisms. Here we report on a study in which twenty-nine (29) caves were inventoried for cavernicolous invertebrates between 2 June and 4 August 2005. Environmental data collected during the study shows that most of the lava tube caves examined have a dark zone varying in temperature from just above freezing to about 12 ºC, where relative humidity varies from about 85 to 100 %. In 193 samples (hand collections, Berlese funnel samples, pitfall trap samples, or sight records), we recorded 1,511 specimens. Of the animals recorded, 22.6% were flies (Insecta: Diptera), 19.3% were springtails (Insecta: Collembola), 16% were spiders (Arachnida: Araneae), 12.2% were millipedes (Diplopoda), 11.7% were mites (Arachnida: Acari), and 5.3% were diplurans (Insecta: Diplura). A variety of other animal taxa make up the remaining 12.9%.
