FROM EGGS TO HATCHLINGS: NEST SITE TAPHONOMY OF AMERICAN CROCODILE ( CROCODYLUS ACUTUS ) AND BROAD-SNOUTED CAIMAN ( CAIMAN LATIROSTRIS )
ABSTRACT The Marias River canyon in north-central Montana, incised into Upper Cretaceous strata of the Great Plains during latest Pleistocene to Holocene time, served as a locus of human activity tied to the unique floral and faunal resources it provided ancient peoples. Erosion of the main canyon walls resulted in deposition of tributary junction alluvial fans characterized by debris-flow and hyperconcentrated flow sediment transport processes where side canyons emerged onto the alluvial valley floor. These alluvial-fan deposits preserve Late Precontact archaeological remains accessible due to their postburial exposure where partially eroded by the meandering channel of the Marias River (Goose Bill site complex). Archaeological materials are also preserved high on the dissected canyon walls where movement of hillslope sediment and colluvium by sheetwash led to their burial (Sparrowhawk site). Deposition of sediment of contrasting physical attributes (grain size, sorting, clay mineral content) within the canyon influences soil substrate properties, favoring growth of specialized plant communities in both alluvial-fan and fluvial environments. These relations exemplify the strong geoecological connections among depositional environment and sediment characteristics, substrate properties, and vegetation community development. The plant communities, interacting in conjunction with the physical landscape, provided a range of habitats utilized by such large mammals as plains bison, Rocky Mountain elk, Audubon sheep, pronghorn, Rocky Mountain mule deer, and white-tailed deer. Four major bison bone layers, some including bison hair and other soft tissues, with associated stone arrow points and stone flakes (artifacts) and evidence of bone processing are preserved in alluvial-fan deposits exposed along the bank of the Marias River at the Goose Bill site complex. These relations illustrate: (1) human activities dating to ~100-595 yr B.P. (falling within the Late Precontact Period of regional archaeological prehistory) that reflect subsistence reliance on bison as a food source, (2) the importance of tributary alluvial fans proximal to canyon walls in preserving archaeological remains, and (3) the role of the meandering Marias River channel in destroying these deposits over a time period of <100 yr. Sediment deposition by overland flow higher up the canyon walls at the Sparrowhawk site preserves a somewhat older (710-830 yr B.P.) archaeological record suggestive of a broader spectrum of resource (food) processing spatially decoupled from an area of bison kill/death.

Dinosaurs and dunes! Sedimentology and paleontology of the Mesozoic in the Valley of Fire State Park
Abstract This field trip covers sedimentological and paleontological research being conducted on the Jurassic Aztec Sandstone and Lower Cretaceous Willow Tank Formation in Valley of Fire State Park. Valley of Fire State Park is located in southern Nevada, just outside of the town of Overton. The Jurassic Aztec Sandstone is equivalent to the Navajo and Nugget Sandstones; these formations together record an aerially large erg complex along the western margin of North America during the time of deposition. Invertebrate and vertebrate ichnofossils are not uncommon in portions of these Jurassic formations. The Willow Tank Formation is composed of the deposits of both a braided and anastomosed fluvial system. This system drained off the paleohigh of the Sevier fold and thrust front to the west, during Early Cretaceous time. Recently a diverse vertebrate assemblage has been discovered from this formation. The fauna of the Willow Tank Formation are similar to other Early Cretaceous faunas from western North America. The vertebrate remains recovered include three taxa of fish, three to four taxa of turtle, crocodilian, iguanodontian, thyreophoran, dromaeosaur, tyrannosauroid, two theropod ootaxa, and a titanosauriform. In addition to the vertebrate elements, two fern morphotypes have been found. Through the course of this field trip participants will see extensive exposures of Aztec Sandstone, including vertebrate ichnofossils. Participants will also hike to vertebrate bearing-beds of the Willow Tank Formation.
