Among those commodities with large tonnage are sand and gravel and stone—both crushed and dimension, mainly limestone but also with a limited amount of sandstone. Sand and gravel are obtained primarily from pits in western Kansas and from pits and dredging in rivers and floodplains in the central and eastern part of the state. Crushed stone for aggregates and for use in cement production is mainly from limestone units of Pennsylvanian age in eastern Kansas, and the dimension stone is now cut from Lower Permian limestone units. Outstanding buildings in the past were also constructed from limestone rocks from Middle and Upper Pennsylvanian and Upper Cretaceous limestone units. Clay and shale from Pennsylvanian and Cretaceous units are used for manufacture of structural clay products, brick, and lightweight aggregate and in Portland and masonry cement manufacture. Salt is a major industrial mineral important to the state. It is produced from the thick Hutchinson Salt Member in the Lower Permian Wellington Formation that is present in the subsurface in a large part of central Kansas. The salt is mined by room-and-pillar methods at three locations, and salt is also produced by solution mining from four different brine fields. -

The Cleveland Museum of Natural History March 2013 Number 58:54–60 PECCARIES (MAMMALIA, ARTIODACTYLA, TAYASSUIDAE) FROM THE MIOCENE-PLIOCENE PIPE CREEK SINKHOLE LOCAL FAUNA, INDIANA DONALD R. PROTHERO Department of Vertebrate Paleontology Natural History Museum, 900 Exposition Blvd., Los Angeles, California 90007 [email protected] HOPE A. SHEETS Department of Biology Trine University, One University Ave., Angola, Indiana 46703 [email protected] ABSTRACT The Pipe Creek Sinkhole local fauna from near Swayzee, Grant County, Indiana, yields an interesting mixture of both plant and animal fossils, including previously unidentified peccaries. The fossil mammals suggest either a latest Hemphillian (latest Miocene-Pliocene) or earliest Blancan (earliest Pliocene) age for the assemblage. The peccaries can be assigned to two taxa: Catagonus brachydontus, a large species with brachydont, bunodont cheek teeth, found in the latest Miocene of Mexico, Florida, and Oklahoma, which is related to the living Chacoan peccary C. wagneri, and Platygonus pollenae, a newly described latest Miocene taxon. The latter is the smallest and most primitive species known from the lineage which culminated with the flat-headed peccaries (Platygonus compressus) common in the Pleistocene. Both of these species are unknown from the early Blancan, and support (along with the rhinos and other taxa) a latest Hemphillian age for the fauna. Introduction AMNH in January 2009, the systematics of North American late The Pipe Creek Sinkhole biota was discovered in an ancient Miocene-Pliocene peccaries had not been resolved well enough to sinkhole deposit eroded into the underlying Silurian limestones make a reliable comparison with valid taxa.

First Mio-Pliocene Salamander Fossil Assemblage from the Southern Appalachians
Palaeontologia Electronica http://palaeo-electronica.org First Mio-Pliocene salamander fossil assemblage from the southern Appalachians Grant S. Boardman and Blaine W. Schubert ABSTRACT The Gray Fossil Site (GFS) of northeastern Tennessee has yielded a diverse sala- mander fossil assemblage for the southern Appalachian Mio-Pliocene. This assem- blage includes at least five taxa (Ambsytoma sp.; Plethodon sp., Spelerpinae, gen. et sp. indet., Desmognathus sp.; and Notophthalmus sp.) from three families (Ambystom- atidae, Plethodontidae, and Salamandridae, respectively). All taxa are present in the area today and support a woodland-pond interpretation of the site. Reported speci- mens represent the earliest record of their families in the Appalachian Mountains (and the earliest record of Plethodontidae and Ambystomatidae east of the Mississippi River); with the Notophthalmus sp. vertebrae being the only Mio-Pliocene body fossil known for the Salamandridae in North America. The Desmognathus sp. specimens may help shed light on the evolutionary origins of the genus Desmognathus, which pur- portedly has its roots in this region during the Mio-Pliocene. Grant S. Boardman.

Geologic History of New Hope Cave, Manitowoc County, Wisconsin
Geologic History of New Hope Cave, Manitowoc County, Wisconsin John A. Luczaj ([email protected]) and Ronald D. Stieglitz ([email protected]) Department of Natural & Applied Sciences University of Wisconsin - Green Bay 2420 Nicolet Drive Green Bay, WI 54311 INTRODUCTION This article presents the preliminary results of an ongoing study of the geologic history of New Hope Cave in Cherney Maribel Caves County Park, Manitowoc County, Wisconsin. The sediments in the cave contain an important record of the events responsible for filling the cave, and may shed light on the geological processes operating on the surface. A brief introduction to the regional geology of northeastern Wisconsin is given here to help the reader place this research into a broader context. GEOLOGIC SETTING The bedrock of Northeastern Wisconsin is primarily composed of the sedimentary rocks dolostone, shale, and sandstone that were deposited during the first half of the Paleozoic Era between 540 and 350 million years ago (Figure 1). Most of these were deposited in warm shallow oceans when this part of North America was situated very near the equator, and at times when global sea level was episodically higher. The limestone deposited in those oceans was altered into a new type of magnesium-rich carbonate rock, known as dolostone (made from the mineral dolomite), by water- rock interaction processes early in their history (Luczaj, 2006). As a result, northeastern Wisconsin’s caves are hosted exclusively by dolostone. In total, up to 600 meters (~2,000 feet) of Paleozoic sedimentary rocks are preserved in the area Figure 1.

A Fossil Shrew (Mammalia, Soricidae) from the Pipe Creek Sinkhole (Late Neogene: Hemphillian), Indiana
2012. Proceedings of the Indiana Academy of Science 121(1):79–86 A FOSSIL SHREW (MAMMALIA, SORICIDAE) FROM THE PIPE CREEK SINKHOLE (LATE NEOGENE: HEMPHILLIAN), INDIANA Nicholas J. Czaplewski: Oklahoma Museum of Natural History, 2401 Chautauqua Avenue, University of Oklahoma, Norman, OK 73072 USA James O. Farlow and Anne Argast: Department of Geosciences, Indiana-Purdue University, 2101 East Coliseum Boulevard, Fort Wayne, IN 46805 USA ABSTRACT. The Pipe Creek Sinkhole is one of two localities in interior eastern North America of late Neogene age (Miocene-Pliocene boundary) preserving fossils of diverse terrestrial vertebrates. This paper documents the occurrence of the sole soricid from the Pipe Creek Sinkhole, a long-tailed shrew of the genus Sorex. Two specimens recovered by screenwashing sediments consist of portions of lower jaws, one containing the m2 (second lower molar) and nearly complete posterior portion of the jawbone with articular condyle, and the other containing the m1 (first lower molar). The two specimens possibly represent one individual, and are not identifiable to species. Many present-day species of Sorex shrews exist across North America and they inhabit a wide variety of habitats, but most often moist, wooded microenvironments. Based on the fossil shrew, we infer the presence of a relatively mesic wooded environment in the vicinity of the Pipe Creek Sinkhole in the late Neogene; such an interpretation does not necessarily conflict with paleoenvironmental interpretations based on other evidence from the locality suggesting open savanna or parkland including pine, hickory, and other flowering plants.

A New Late Neogene Ground Squirrel (Rodentia, Sciuridae) from the Pipe Creek Sinkhole Biota, Indiana
2019. Proceedings of the Indiana Academy of Science 128(1):73–86 A NEW LATE NEOGENE GROUND SQUIRREL (RODENTIA, SCIURIDAE) FROM THE PIPE CREEK SINKHOLE BIOTA, INDIANA H. Thomas Goodwin1: Department of Biology, Andrews University, Berrien Springs, MI 49104 USA James O. Farlow: Department of Biology, Purdue University Fort Wayne, Fort Wayne, IN 46805 USA ABSTRACT. The Pipe Creek Sinkhole of eastern Indiana has yielded a diverse assemblage of late Neogene plants and vertebrates, documenting a mix of local habitats including both aquatic and upland open habitat. It represents one of few late Neogene fossil assemblages from the interior of eastern North America. A new species of ground squirrel is described from this fossil assemblage based on a partial dentary with all cheek teeth and numerous isolated teeth. This moderately-sized ground squirrel exhibits generally plesiomorphic, low-crowned cheek teeth that were narrow across their trigonids. It also has a p4 that uniquely lacks a buccally-directed hypoconid. The ground squirrel is tentatively assigned to the extant genus Ictidomys Allen, 1877 and represents the sole Neogene ground squirrel known only from eastern North America. The presence of this new ground squirrel in the Pipe Creek Sinkhole biota suggests that the late Neogene diversification of ground squirrels, well documented in the American West and on the Great Plains, may have extended into eastern North America and confirms the presence of open habitat within the sampling area of the fossil assemblage.
