Metriorhynchid crocodylomorphs from the lower Kimmeridgian of 20 21 Southern Germany: evidence for a new large-bodied geosaurin lineage in Europe. Alcheringa XXX, X–X. ISSN 22 23 0311-5518 24 25 26 27 Over the last two centuries, numerous exquisitely preserved thalattosuchian crocodylomorph skeletons have been 28 29 found in the Jurassic strata of Southern Germany. While the majority of these specimens occur in Toarcian and 30 31 upper Kimmeridgian–lower Tithonian deposits, thalattosuchian remains are otherwise rare in strata representing 32 33 different stages of the Jurassic. Here, we describe skeletal elements from two large-bodied thalattosuchians 34 35 attributable to the family Metriorhynchidae — these were recovered from lower Kimmeridgian sediments in 36 37 Bavaria and Baden-Württemberg, respectively. These new metriorhynchid fossils are closely comparable in both 38 39 stratigraphic age and dental morphology, and thus may be congeneric. Furthermore, our phylogenetic analysis 40 41 suggests affinity with metriorhynchid remains from France, Switzerland, and the United Kingdom. We interpret 42 these taxa as members of an as yet unnamed geosaurine metriorhynchid lineage (herein termed the “E-clade”) 43 44 from the Kimmeridgian and Tithonian of Europe, which appears to be related to species of Torvoneustes from 45 46 England and Mexico, and Purranisaurus potens from Argentina, collectively contributing to “Subclade T” of the 47 48 tribe Geosaurini. Finally, the metriorhynchid material described herein suggests preservation as a “bloat and 49 50 float” carcass that underwent diagenetic dispersal within a limestone-marl-alternation deposited in an off-shore 51 52 epicontinental marine environment. 53 54 55 56 Pascal Abel [[email protected]], Senckenberg Centre for Human Evolution and Palaeoenvironment, 57 58 Eberhard-Karls-University Tübingen, Sigwartstraße 10, 72076 Tübingen, Germany.

Andrews 1913, Westphal 1962, 18 For Peer Review Only 19 20 Wilberg 2012, Chiarenza et al. 2015, Fanti et al. 2016). Early in their evolution, 21 22 thalattosuchians split into two subclades: the Teleosauroidea and Metriorhynchoidea (Young 23 24 & Andrade 2009). In Germany, teleosauroids are well known from abundant skeletons found 25 26 27 in the Holzmaden area of Baden-Württemberg (e.g. Westphal 1962). Metriorhynchoids are 28 29 comparatively less common, with the most complete remains discovered in the upper Upper 30 31 Jurassic limestones of Southern Germany (e.g. Fraas 1901, 1902, Young & Andrade 2009, 32 33 Sachs et al. 2019a). Fragmentary metriorhynchid skeletons have also been documented from 34 35 36 the Middle Jurassic (e.g. Michelis et al. 1996, Waskow et al. 2017) and Lower Cretaceous 37 38 (Koken 1883, Schröder 1921) of western and northern Germany. 39 40 In Southern Germany, thalattosuchian fossils are mainly restricted to Toarcian and upper 41 42 43 Kimmeridgian/lower Tithonian strata (e.g. Wagner 1852, Fraas 1902, Westphal 1962, 1965, 44 45 Sachs et al. 2019a, b). Dietl & Etzold (1977), Abel et al. (2018), and Aiglstorfer et al. (2019) 46 47 additionally reported fragmentary material from the Aalenian of Baden-Württemberg. 48 49 50 Wellnhofer (1978) described several vertebrae from the middle Oxfordian near Sengenthal in 51 52 Bavaria, which he assigned to Steneosaurus Geoffroy Saint-Hilaire, 1825. The currently best- 53 54 preserved specimen is the holotype of the teleosauroid Machimosaurus buffetauti Young et 55 56 al., 2015a from the lower Kimmeridgian Lacunosamergel Formation near Neuffen in Baden- 57 58 59 Württemberg (Young et al. 2014). 60 2 URL: http://mc.manuscriptcentral.com/talc E-mail: [email protected] Page 3 of 173 Alcheringa 1 2 3 Here, we identify two new unpublished metriorhynchid specimens from the Upper Jurassic 4 5 6 lower Weißjura Group of Southern Germany. The first, SMNS 80149, comprises the anterior 7 8 section of adentary with several in situ teeth. The fossil was found by Alfons Berreth in the 9 10 1950s or 1960s on Braunenberg hill near Aalen-Wasseralfingen in eastern Baden- 11 12 Württemberg. The second specimen, PSHME PH1 incorporates disarticulated postcranial 13 14 15 elements and some associated teeth. It was discovered in 1999 by members of the 16 17 Landesverband für Höhlen- und Karstforschung Bayern (LHK) at the Reichold limestone 18 For Peer Review Only 19 quarry near Drügendorf in northern Bavaria (see Weisel 2000, Abel 2016).

    A CRITICAL EVALUATION OF THE LOWER-MIDDLE PALAEOLITHIC ARCHAEOLOGICAL RECORD OF THE CHALK UPLANDS OF NORTHWEST EUROPE The Chilterns, Pegsdon, Bedfordshire (photograph L. Blundell) Lesley Blundell UCL Thesis submitted for the degree of PhD September 2019 2 I, Lesley Blundell, confirm that the work presented in this thesis is my own. Where information has been derived from other sources, I confirm that this has been indicated in the thesis. Signed: 3 4 Abstract Our understanding of early human behaviour has always been and continues to be predicated on an archaeological record unevenly distributed in space and time. More than 80% of British Lower-Middle Palaeolithic findspots were discovered during the late 19th/early 20th centuries, the majority from lowland fluvial contexts. Within the British planning process and some academic research, the resultant findspot distributions are taken at face value, with insufficient consideration of possible bias resulting from variables operating on their creation. This leads to areas of landscape outside the river valleys being considered to have only limited archaeological potential. This thesis was conceived as an attempt to analyse the findspot data of the Lower-Middle Palaeolithic record of the Chalk uplands of southeast Britain and northern France within a framework complex enough to allow bias in the formation of findspot distribution patterns and artefact preservation/discovery opportunities to be identified and scrutinised more closely. Taking a dynamic, landscape = record approach, this research explores the potential influence of geomorphology, 19th/early 20th century industrialisation and antiquarian collecting on the creation of the Lower- Middle Palaeolithic record through the opportunities created for artefact preservation and release.

  • Chapter 2 Physical Characteristics of the Study Area
    CHAPTER 2 PHYSICAL CHARACTERISTICS OF THE STUDY AREA 2.1. Location of study area The study area incorporates part of north Hertfordshire, south and mid- Bedfordshire as well as the southwest corner of Cambridgeshire and lies approximately 40 km north of London (Figure 1.1). Coverage of the area by British Geological Survey (BGS) 1:50,000 map sheets is shown in Figure 2.1. 2.2. Bedrock geology The strikes of the solid geological formations are approximately northeast- southwest across the study area (Figure 2.2). The solid geological succession is shown in Table 2.1. To the northwest of the Chiltern Hills the Gault Clay forms a rich agricultural landscape, representing a continuation of the Vale of Aylesbury. Beyond this, running approximately from Bow Brickhill (SP915343) to Gamlingay (TL234525) is a discontinuous ridge formed by the Woburn Sands Formation, part of the Lower Greensand. This prominent ‘Greensand Ridge’, rising to 170 m O.D. at Bow Brickhill, separates the Cretaceous clays from the Jurassic Oxford and Ampthill Clays to the northwest. The oldest formation is recorded in a borehole (TL23NE1) at Ashwell (TL286390), where Devonian strata were reached at a depth of 186.54 m, i.e. 93 m below O.D. (Smith, 1992). Lying just beyond the northern boundary of the present study area, north of the River Ouse, a borehole (TL15NE2) at Wyboston (TL175572) penetrated Ordovician rocks of Tremadoc age at a depth of approximately 230 m (Moorlock et al ., 2003). The Oxford Clay of the Upper Jurassic represents the oldest formation outcropping within the study area.

  • Earth-Science Reviews
    Earth-Science Reviews Predicting shoreline depositional process regimes using insights from palaeotidal modelling --Manuscript Draft-- Manuscript Number: Article Type: Review Article Keywords: Numerical Modelling; Wave; Tide; Fluvial; Palaeotidal; Mixed process; Shoreline; Deltaic; Shelf; Sedimentary Preservation Corresponding Author: Daniel Collins Shell International Ltd London, London UNITED KINGDOM First Author: Daniel Collins Order of Authors: Daniel Collins Alexandros Avdis Martin H. Wells Andrew J. Mitchell Peter A. Allison Howard D. Johnson Gary J. Hampson Jon Hill Christopher D. Dean Matthew D. Piggott Abstract: Tides are a fundamental element of predictive depositional models of ancient shoreline process regimes. These models principally relate ancient tidal potential to shelf width (c. 10–100 km) and shoreline geometry (c. 1–10 km) but rarely consider larger-scale basin physiography (100–1000 km) or variability related to changing shoreline geometry. A refined predictive decision tree for ancient shoreline process regimes is developed based on a review of modern shoreline processes, supported by new insight from numerical palaeotidal modeling studies. Modern depositional shorelines are overwhelmingly wave dominated, suggesting a first-order control of wave fetch and wave-generating wind conditions on shoreline processes. Several numerical palaeotidal modeling studies highlight the following controls on tidal processes: (1) 100–1000 km-scale basin physiography on tidal inflow versus outflow; (2) 10–100 km- scale shelf physiography on shelf tidal resonance potential; (3) tidal amplification (funnelling and shoaling) versus frictional effects in shoreline embayments (1–10 km scale); and (4) palaeogeographic uncertainty, which affects prediction of these latter three controls. The predictive decision tree considers the effects of basin physiography, shelf width and shoreline morphology on wave, tide and fluvial processes separately.

  • The Mapping of Landscapes, Geology and Soils of Bedfordshire
    We use the words landscape and landform to refer to natural (not man-made) features visible on the surface of the Earth. The word landscape is used for larger areas of varied topography, whereas the The Mapping of Landscapes, Geology and word landform is used for smaller features that occur within landscapes, and can often be readily seen to have resulted from the local action of particular surface processes (for example, slope failure or Soils of Bedfordshire & Cambridgeshire river erosion). In this study we present a group of regional landscape maps (Maps 1-4), and a group of more local maps (Maps 5-8) on a larger scale, where landforms are more easily distinguished. Our work has been part-funded by Natural England and facilitated by Geo-East, the East of England Geodiversity Partnership. Landscapes and their component landforms have formed during the long-term geological history of an area, and may have been influenced by many factors. These include, a) the materials present just below the Earth’s surface, b) movements of the Earth’s land or sea surface, and c) the action of ice, rain, wind and living organisms. This study has been concerned particularly with ways of analysing and presenting topographical information, so that members of the general public can gain new insights into the stories that have resulted in their landscapes and landforms. Maps are routinely used to represent landscapes and landforms, and we have wanted to experiment with the ways that computer-based Geographical Information System (GIS) software, using the digital regional datasets now available, has transformed our ability to provide vivid representations of our surroundings.
