CITATION EAST KIRKTON QUARRY SITE OF SPECIAL SCIENTIFIC INTEREST West Lothian Site code: 586 NATIONAL GRID REFERENCE: NS 990691 OS 1:50,000 SHEET NO: Landranger Series 65 1:25,000 SHEET NO: Explorer Series 349 AREA: 2.43 hectares NOTIFIED NATURAL FEATURES Geological: Palaeontology: Arthropoda (excluding insects and trilobites) Palaeontology: Permian-Carboniferous Fish/Amphibia DESCRIPTION: Situated on the northern outskirts of Bathgate, West Lothian, East Kirkton Quarry is a disused, tree-lined limestone quarry, cut into a gently sloping agricultural landscape. The limestones were formed towards the beginning of the Carboniferous period, between 338 and 340 million years ago, when the area was a hot mineral spring within an active volcanic region. The highly mineralised spring water provided excellent conditions for the fossilisation of organic matter. The site has yielded a rich terrestrial fauna and flora that is remarkably well preserved, including the first fully-articulated amphibians found in Scotland. Seven species of fully land-going amphibians have been recognised to date, the commonest being a primitive form of temnospondyl, similar to Dendrerpeton. At least two species of anthracosaur, the forerunners of reptiles, have also been found within the quarry. Perhaps the best known specimen recovered from the site is Westlothiana lizziae, which bore some resemblance to modern-day lizards. Invertebrate fossils are also present within the East Kirkton limestones, with significant finds including: eurypterids (water scorpions), such as Hibbertopterus; the world’s oldest opilionid (harvestman spider); millipedes; and scorpions. Many of the fossils found significantly pre-date similar remains from other areas of the world. This, combined with the richness of the fossil biota and the exceptionally high quality of the specimens obtained from the quarry, make this a site of international importance for the study of early Carboniferous life. NOTIFICATION HISTORY First notified under the 1981 Act: 20 May 1993 Notification reviewed under the 2004 Act: 24 March 2010 REMARKS Measured area of site corrected (from 2.4 ha) .

Morphology, Phylogeny, and Evolution of Diadectidae (Cotylosauria: Diadectomorpha)
Morphology, Phylogeny, and Evolution of Diadectidae (Cotylosauria: Diadectomorpha) by Richard Kissel A thesis submitted in conformity with the requirements for the degree of doctor of philosophy Graduate Department of Ecology & Evolutionary Biology University of Toronto © Copyright by Richard Kissel 2010 Morphology, Phylogeny, and Evolution of Diadectidae (Cotylosauria: Diadectomorpha) Richard Kissel Doctor of Philosophy Graduate Department of Ecology & Evolutionary Biology University of Toronto 2010 Abstract Based on dental, cranial, and postcranial anatomy, members of the Permo-Carboniferous clade Diadectidae are generally regarded as the earliest tetrapods capable of processing high-fiber plant material; presented here is a review of diadectid morphology, phylogeny, taxonomy, and paleozoogeography. Phylogenetic analyses support the monophyly of Diadectidae within Diadectomorpha, the sister-group to Amniota, with Limnoscelis as the sister-taxon to Tseajaia + Diadectidae. Analysis of diadectid interrelationships of all known taxa for which adequate specimens and information are known—the first of its kind conducted—positions Ambedus pusillus as the sister-taxon to all other forms, with Diadectes sanmiguelensis, Orobates pabsti, Desmatodon hesperis, Diadectes absitus, and (Diadectes sideropelicus + Diadectes tenuitectes + Diasparactus zenos) representing progressively more derived taxa in a series of nested clades. In light of these results, it is recommended herein that the species Diadectes sanmiguelensis be referred to the new genus

We have incorporated, where possible, original observations of numerous taxa spread throughout the major tetrapod clades. A stem-based (total-group) definition of Tetrapoda is preferred over apomorphy- and node-based (crown-group) definitions. This definition is operational, since it is based on a formal character analysis. A PAUP* search using a recently implemented version of the parsimony ratchet method yields 64 shortest trees. Differ- ences between these trees concern: (1) the internal relationships of aı¨stopods, the three selected species of which form a trichotomy; (2) the internal relationships of embolomeres, with Archeria

Geological Guide to the Fossil Grove, Glasgow
A Geological Guide to the Fossil Grove, Glasgow by Iain Allison and David Webster Geological Society of Glasgow About this Guide About this Guide This new booklet on the geology of the Fossil Grove is aimed everyone with an interest in geology, however slight - but it does contain more detail for students, professionals and academics alike and for whom some further reading is suggested. A separate section on the geological framework of the Glasgow area is included, and for the beginner unfamilar with some technical terms, a short glossary is included. This guide includes several localities in the quarry area - which is always open. The Fossil House itself is open on weekend afternoons from April- October. The descriptions of the localities in the guide uses two font styles - the text in italics contains the geological descriptions and interpretations at each locality; whereas the regular font style is used for directions, history and other points of interest. This booklet replaces two booklets (now out-of-print) produced by Glasgow City Council in 1972 and 1995. A new updated Guide to the Geology of Glasgow is being produced by the Geological Society of Glasgow - and this booklet on the Fossil Grove will form an integral part of it which will replace the out-of-print ‘Geological Excursions around Glasgow and Girvan’ published by the Society in 1992. This guide has been produced by the Geological Society of Glasgow with generous support from the Fossil Grove Trust. Technical and editorial contributions from volunteers, friends and supporters are also gratefully acknowledged. Fig. A1.

Early Vertebrate Evolution New Insights Into the Morphology of the Carboniferous Tetrapod Crassigyrinus Scoticus from Computed Tomography Eva C
Earth and Environmental Science Transactions of the Royal Society of Edinburgh, 109, 157–175, 2019 (for 2018) Early Vertebrate Evolution New insights into the morphology of the Carboniferous tetrapod Crassigyrinus scoticus from computed tomography Eva C. HERBST* and John R. HUTCHINSON Structure and Motion Laboratory, Department of Comparative Biomedical Sciences, Royal Veterinary College, University of London, Hatfield, Hertfordshire AL9 7TA, UK. Email: [email protected] *Corresponding author ABSTRACT: The Carboniferous tetrapod Crassigyrinus scoticus is an enigmatic animal in terms of its morphology and its phylogenetic position. Crassigyrinus had extremely reduced forelimbs, and was aquatic, perhaps secondarily. Recent phylogenetic analyses tentatively place Crassigyrinus close to the whatcheeriids. Many Carboniferous tetrapods exhibit several characteristics associated with terrestrial locomotion, and much research has focused on how this novel locomotor mode evolved. However, to estimate the selective pressures and constraints during this important time in vertebrate evolution, it is also important to study early tetrapods like Crassigyrinus that either remained aquatic or secondarily became aquatic. We used computed tomographic scanning to search for more data about the skeletal morphology of Crassigyrinus and discovered several elements previously hidden by the matrix. These elements include more ribs, another neural arch, potential evidence of an ossified pubis and maybe of pleurocentra. We also discovered several additional metatarsals with interesting asymmetrical morphology that may have functional implications. Finally, we reclassify what was previously thought to be a left sacral rib as a left fibula and show previously unknown aspects of the morphology of the radius. These discoveries are examined in functional and phylogenetic contexts. KEY WORDS: evolution, palaeontology, phylogeny, water-to-land transition.

Their adaptations to the aquatic environment are well known and include putative viviparity, along with the presence of several skeletal characters such as a long, laterally compressed tail, long limbs, the foot larger than the manus, and presence of pachyosteosclerotic bones. They were also described as possessing non-coossified girdle bones and incompletely ossified epiphyses, although there could be an early fusion of the front girdle bones to form the scapulocoracoid in some specimens. Some of these features, however, are shared by most basal tetrapods that are considered semiaquatic and even some terrestrial ones. The study of vertebral columns and limbs provides essential clues about the locomotor Edited by: system and the lifestyle of early amniotes. In this study, we have found that the variation of Martin Daniel Ezcurra, the vertebral centrum length along the axial skeleton of Mesosaurus tenuidens fits better Museo Argentino de Ciencias Naturales Bernardino Rivadavia, with a semi-aquatic morphometric pattern, as shown by comparisons with other extinct Argentina and extant taxa.

Edinburgh & West Lothian
Edinburgh & West Lothian: A landscape fashioned by geology The tranquil appearance of the city of Edinburgh nestling between the surrounding hills and the undulating countryside of West Lothian belies their dramatic volcanic past. The Lothian landscape took over 400 million years to reach its present shape. This book tells the story of its journey from erupting volcanoes, through rivers, seas and ice-caps, to the peaceful parks, restored quarries and level playing fields we see today. West Lothian EDINBURGHA LANDSCAPE FASHIONED & BY GEOLOGY There is probably no place in the world which better exemplifies "A Landscape Fashioned by GEOLOGY Lothian: & West A LANDSCAPEEDINBURGH BY FASHIONED Geology" than the area around Edinburgh. Here you can follow in the footsteps of James Hutton, the Father of Modern Geology, see what he saw, and better understand the processes that formed Edinburgh’s dramatic landscape. This booklet is beautifully accessible, taking you on a journey from today’s familiar hills and valleys to the icy wastes of two million years ago and further back, to the volcanoes and coal swamps of 350 million years ago when Edinburgh lay at the equator. What more exciting story could there be than the story in the rocks and landscapes of Edinburgh. Dr Stuart Monro, Scientific Director, Our Dynamic Earth About the Author David McAdam has spent a lifetime mapping and describing the geology of east central Scotland. He has contributed to three other titles in the `Landscape Fashioned by Geology ' series. Although recently retired, he remains a Visiting Scientist with the British Geological Survey to continue his interest in promoting Scotland's geological heritage.
