Analysis of a Sponge Bioherm from the Hermosa Group, Molas Lake Area, Colorado Joanna Hamilton Bowling Green State University Department of Geology April 2013 Introduction: The Hermosa Group The Hermosa Group is a Pennsylvanian (~310 Ma) rock unit found in the southwestern San Juan Mountains and the Paradox Basin. The Paradox Basin is a northwest-southeast trending basin related to the Uncompahgre Uplift in the north, salt deposition and movement throughout, and a Precambrian fault system in the underlying basement rocks (Brown 2002, Trudgill and Arbuckle 2009). The Uncompahgre Uplift occurred in response to the Ouachita – Marathon Orogeny (related to the Ancestral Rocky Mountains Orogeny) caused by the collision of North America and South America-Africa during the Late Mississippian (~ 320 Ma) (Trudgill and Arbuckle 2009, Pazzaglia et al. 1999). The Paradox Basin formed as a complimentary subsidence basin alongside the uplifted area (Brown 2002). When the basin subsided, smaller structural features formed within it, including step-down grabens close to the uplift and folded areas further away (Baars and Stevenson 1981, Brown 2002). -

An Inventory of Trilobites from National Park Service Areas
Sullivan, R.M. and Lucas, S.G., eds., 2016, Fossil Record 5. New Mexico Museum of Natural History and Science Bulletin 74. 179 AN INVENTORY OF TRILOBITES FROM NATIONAL PARK SERVICE AREAS MEGAN R. NORR¹, VINCENT L. SANTUCCI1 and JUSTIN S. TWEET2 1National Park Service. 1201 Eye Street NW, Washington, D.C. 20005; -email: [email protected]; 2Tweet Paleo-Consulting. 9149 79th St. S. Cottage Grove. MN 55016; Abstract—Trilobites represent an extinct group of Paleozoic marine invertebrate fossils that have great scientific interest and public appeal. Trilobites exhibit wide taxonomic diversity and are contained within nine orders of the Class Trilobita. A wealth of scientific literature exists regarding trilobites, their morphology, biostratigraphy, indicators of paleoenvironments, behavior, and other research themes. An inventory of National Park Service areas reveals that fossilized remains of trilobites are documented from within at least 33 NPS units, including Death Valley National Park, Grand Canyon National Park, Yellowstone National Park, and Yukon-Charley Rivers National Preserve. More than 120 trilobite hototype specimens are known from National Park Service areas. INTRODUCTION Of the 262 National Park Service areas identified with paleontological resources, 33 of those units have documented trilobite fossils (Fig. 1). More than 120 holotype specimens of trilobites have been found within National Park Service (NPS) units. Once thriving during the Paleozoic Era (between ~520 and 250 million years ago) and becoming extinct at the end of the Permian Period, trilobites were prone to fossilization due to their hard exoskeletons and the sedimentary marine environments they inhabited. While parks such as Death Valley National Park and Yukon-Charley Rivers National Preserve have reported a great abundance of fossilized trilobites, many other national parks also contain a diverse trilobite fauna. -

The vast majority of evaporite clay minerals are authigenic. The most common are illite, chlorite, smectite and disordered mixed-layer illite-smectite and chlorite-smectite; all the clay minerals are included regardless of their quantity. Corrensite, sepiolite, palygorskite and talc are very unevenly distributed in the Phanerozoic. Other clay minerals (perhaps with the exception of kaolinite) are very rare. Evaporites precipitated during periods of SO4-rich seawater type are characterized by both a greater number and a greater variety of clay minerals—smectite and mixed-layer minerals, as well as Mg-corrensite, palygorskite, sepiolite, and talc, are more common in associations. -

Abstract The Pennsylvanian/Permian Hermosa Formation in southwestern Colorado is composed of arkosic sandstone, marine limestone, and shale that formed at a time when the region consisted of open-marine carbonate shelves and coastal plains. During the time of deposition, there were many tectonically active highlands in the region, including the Ancestral Rocky Mountains, San Luis Highlands, and the Uncompahgre, Emery, Zuni-Defiance-Kaibab Uplifts. Previous studies have attributed the source of the main sediment supply of the Hermosa Formation to the Uncompahgre branch of the Ancestral Rocky Mountains with smaller amounts of elastics from the Defiance-Zuni uplifts (Wengerd and Matheny, 1958; Wengerd and Strickland, 1954; Baars and Stevenson, 1981). -
