LUCAS2 1Ru¨bezahlstraße 1, D-92318 Neumarkt, Germany 2New Mexico Museum of Natural History, 1801 Mountain Road NW, Albuquerque, NM 87104-1375 USA *Corresponding author (e-mail: [email protected]) Abstract: Triassic tetrapod footprints have a Pangaea-wide distribution; they are known from North America, South America, Europe, North Africa, China, Australia, Antarctica and South Africa. They often occur in sequences that lack well-preserved body fossils. Therefore, the question arises, how well can tetrapod footprints be used in age determination and correlation of stratigraphic units? The single largest problem with Triassic footprint biostratigraphy and biochronology is the non- uniform ichnotaxonomy and evaluation of footprints that show extreme variation in shape due to extramorphological (substrate-related) phenomena. Here, we exclude most of the countless ichnos- pecies of Triassic footprints, and instead we consider ichnogenera and form groups that show distinctive, anatomically-controlled features. Several characteristic footprint assemblages and ichnotaxa have a restricted stratigraphic range and obviously occur in distinct time intervals.

    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.

Rock can be seen at the surface in some of this subregion such as the sea cliffs, cliffs in the North York Moors and in man-made excavations such as quarries or road cuttings. Combined with numerous deep boreholes and some geophysical investigations, this gives us an understanding of the rocks present and their distribution. There are clay-rich rock layers under most of the subregion in which we may be able to site a GDF. There are also layers of rock salt under most of the eastern coastal half of the subregion and extending off the coast, in which we may be able to site a GDF.

    STRATEGIC STONE STUDY A Building Stone Atlas of Lancashire Published December 2011 Derived from BGS digital geological mapping at 1:625,000 scale, British Geological Survey © Lancashire Bedrock Geology NERC. All rights reserved Click on this link to visit Lancashire’s geology and its contribution to known building stones, stone structures and building stone quarries (Opens in new window http://maps.bgs.ac.uk/buildingstone?County=Lancashire ) Lancashire Strategic Stone Study 1 Introduction The bedrock geology of Lancashire is dominated by fine to very coarse-grained SANDSTONES of Carboniferous and, to a lesser extent, Permo-Triassic age. There are, in addition, locally important outcrops of LIMESTONE. The Carboniferous rocks occupy a broad swathe of the east of the county, wrapping around a Triassic ‘core’ in the lowlands of the west, which is largely buried under thick accumulations of glacial till (Quaternary). The competence of the Carboniferous sandstones is reflected in the rugged moorland of east Lancashire, which in turn is reflected in the ‘sturdy’ character of the built landscape. The limestones present in northern Lancashire and around Clitheroe bring a lighter ‘openness’ to the villages of these areas. Lowland Lancashire, meanwhile, is primarily brick country, with the exception of some Triassic sandstone pockets around Ormskirk and Heysham. The widespread availability of durable building stone led to the development of quarrying throughout central and eastern Lancashire, with Rossendale (during the 1870s) exporting vast amounts of building stone to other areas of Britain and also abroad. Only a small number of quarries produce building stone today, with most of the industry now focussing on the supply of crushed stone products.
