Early Eocene climates were globally warm, with ice-free conditions at both poles. Early 16 Eocene polar landmasses supported extensive forest ecosystems of a primarily temperate biota, 17 but also with abundant thermophilic elements such as crocodilians, and mesothermic taxodioid 18 conifers and angiosperms. The globally warm early Eocene was punctuated by geologically brief 19 hyperthermals such as the Paleocene-Eocene Thermal Maximum (PETM), culminating in the 20 Early Eocene Climatic Optimum (EECO), during which the range of thermophilic plants such as 21 palms extended into the Arctic. Climate models have struggled to reproduce early Eocene Arctic 22 warm winters and high precipitation, with models invoking a variety of mechanisms, from 23 atmospheric CO2 levels that are unsupported by proxy evidence, to the role of an enhanced 24 hydrological cycle to reproduce winters that experienced no direct solar energy input yet remained 25 wet and above freezing.

  • Delimiting Geologic Structures Affecting Water Movement of The
    WRIA 54 Delimiting geologic structures affecting water movement and flow direction of the CRBG West Plains aquifer. DOE CONTRACT #11-1056 TECHNICAL MEMORANDUM TO ACCOMPANY THE STRUCTURAL GEOLOGY MAP OF THE WEST PLAINS REGION June 2012 Michael B. McCollum and Chad J. Pritchard Geology Department Eastern Washington University Cheney, Washington 99004-2439 I. INTRODUCTION The West Plains region is located just west of Spokane in Spokane and Lincoln Counties, Washington and is bounded to the north by the Spokane River, south by uplands and basalt scablands, east by Latah Creek and the Spokane Valley Aquifer, and to the west by loess covered hills and basalt lowlands. Increasing development and population growth in the eastern portion of the West Plains requires further understanding of the complex geohydrologic system. The complicated geologic history of eastern Washington and the West Plains spans billions of years and the rock types found in the region can be closely tied to the hydrology of the area. Geohydrology of the Spokane Area is strongly influenced by three major rock types 1) Pre- Neogene basement rock, 2) Miocene Columbia River Basalt Group (CRBG) and sedimentary interbeds (e.g. the Latah formation) that define the Columbia Plateau, and 3) Quaternary alluvium and glacial flood deposits that have molded the scablands of eastern Washington. This report begins with a brief overview of the regional geology and structural history of the mountainous areas adjacent to the West Plains region of the Columbia Plateau region, followed by a summary of our original scientific research on the pre-Neogene rocks and structures exposed in the isolated hills and ridges located in the West Plains as well as high density fracture zones, such as the Cheney Fracture Zone.

Most of these finds were made in Alberta and British Columbia, but the Yukon Territory can lay claim to at least one tracksite and probably has the potential to yield more sites. The record of dinosaur tracks with skin impressions has increased dramatically, and is now represented by specimens of ankylosaurs, large ornithopods, small theropods and tyrannosauroids. Notable new finds include the first record of sauropods in Canada, evidence of herding behavior in ankylosaurs and the first pterosaur tracks in Canada. First discoveries of track specimens from several formations in western Canada include the Mountain Park Member of the Gates Formation in Alberta, and the Boulder Creek, Goodrich, Kaskapau, Cardium and Marshybank formations in northeastern British Columbia.

  • The Giant Pliosaurid That Wasn't—Revising the Marine Reptiles From
    The giant pliosaurid that wasn’t—revising the marine reptiles from the Kimmeridgian, Upper Jurassic, of Krzyżanowice, Poland DANIEL MADZIA, TOMASZ SZCZYGIELSKI, and ANDRZEJ S. WOLNIEWICZ Madzia, D., Szczygielski, T., and Wolniewicz, A.S. 2021. The giant pliosaurid that wasn’t—revising the marine reptiles from the Kimmeridgian, Upper Jurassic, of Krzyżanowice, Poland. Acta Palaeontologica Polonica 66 (1): 99–129. Marine reptiles from the Upper Jurassic of Central Europe are rare and often fragmentary, which hinders their precise taxonomic identification and their placement in a palaeobiogeographic context. Recent fieldwork in the Kimmeridgian of Krzyżanowice, Poland, a locality known from turtle remains originally discovered in the 1960s, has reportedly provided additional fossils thought to indicate the presence of a more diverse marine reptile assemblage, including giant pliosaurids, plesiosauroids, and thalattosuchians. Based on its taxonomic composition, the marine tetrapod fauna from Krzyżanowice was argued to represent part of the “Matyja-Wierzbowski Line”—a newly proposed palaeobiogeographic belt comprising faunal components transitional between those of the Boreal and Mediterranean marine provinces. Here, we provide a de- tailed re-description of the marine reptile material from Krzyżanowice and reassess its taxonomy. The turtle remains are proposed to represent a “plesiochelyid” thalassochelydian (Craspedochelys? sp.) and the plesiosauroid vertebral centrum likely belongs to a cryptoclidid. However, qualitative assessment and quantitative analysis of the jaws originally referred to the colossal pliosaurid Pliosaurus clearly demonstrate a metriorhynchid thalattosuchian affinity. Furthermore, these me- triorhynchid jaws were likely found at a different, currently indeterminate, locality. A tooth crown previously identified as belonging to the thalattosuchian Machimosaurus is here considered to represent an indeterminate vertebrate.
