The Solnhofen Limestone: A stony heritage of many uses Martina Kölbl-Ebert (1), Sabina Kramar (2), and Barry J. Cooper (3) (1) Jura-Museum, Eichstätt, Germany ([email protected]), (2) Slovenian National Building and Civil Engineering Institute, Slovenia ([email protected]), (3) School of Natural & Built Environments University of South Australia, Adelaide, Australia ([email protected] ) High above the valley of the River Altmühl (Bavaria, Germany), between Solnhofen to the west and Kelheim to the east, numerous quarries give access to thinly plated limestone from the Upper Jurassic, some 150 million years before the present. The main quarry areas lie around the town of Eichstätt and between the villages of Solnhofen, Langenaltheim and Mörnsheim. Here limestone slabs have been quarried for several hundred years, some even in Roman times. Solnhofen Limestone is famous worldwide; not only because it is a beautiful building stone of high quality, but also because of the exceptionally well-preserved fossils it contains –among them the early bird Archaeopteryx. The quarry industry between Solnhofen and Eichstätt has shaped a cultural landscape, with old and new quarries sunk into the plain and numerous spoil heaps rising above it, for the rock is not all economically useful. But many of the spoil heaps and the old quarries are environmentally protected as they provide a habitat for some rare plants and animals. It is not necessary to cut the Solnhofen Limestone with a saw: it is split by hand into thin and even slabs or sheets which are used for flagstones and wall covers, which since centuries are sold world-wide. Locally it also serves as roof tiles for traditional houses. Thick slabs of especially fine quality may be found near Solnhofen and Mörnsheim and are used for lithography printing..

    Diapsid Phylogeny and the Origin and Early Evolution of Squamates by Tiago Rodrigues Simões A thesis submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy in SYSTEMATICS AND EVOLUTION Department of Biological Sciences University of Alberta © Tiago Rodrigues Simões, 2018 ABSTRACT Squamate reptiles comprise over 10,000 living species and hundreds of fossil species of lizards, snakes and amphisbaenians, with their origins dating back at least as far back as the Middle Jurassic. Despite this enormous diversity and a long evolutionary history, numerous fundamental questions remain to be answered regarding the early evolution and origin of this major clade of tetrapods. Such long-standing issues include identifying the oldest fossil squamate, when exactly did squamates originate, and why morphological and molecular analyses of squamate evolution have strong disagreements on fundamental aspects of the squamate tree of life. Additionally, despite much debate, there is no existing consensus over the composition of the Lepidosauromorpha (the clade that includes squamates and their sister taxon, the Rhynchocephalia), making the squamate origin problem part of a broader and more complex reptile phylogeny issue. In this thesis, I provide a series of taxonomic, phylogenetic, biogeographic and morpho-functional contributions to shed light on these problems. I describe a new taxon that overwhelms previous hypothesis of iguanian biogeography and evolution in Gondwana (Gueragama sulamericana). I re-describe and assess the functional morphology of some of the oldest known articulated lizards in the world (Eichstaettisaurus schroederi and Ardeosaurus digitatellus), providing clues to the ancestry of geckoes, and the early evolution of their scansorial behaviour.

  • Jurassic Vertebrate Bromalites of the Western United States in the Context of the Global Record
    Volumina Jurassica, 2014, Xii (2): 151–158 Doi: 10.5604/17313708 .1130139 Jurassic vertebrate bromalites of the western United States in the context of the global record Adrian P. HUNT1, Spencer G. LUCAS2 Key words: bromalite, coprolite, consumulite, evisceralite, Jurassic, Morrison Formation, Sundance Formation, western USA. Abstract. The bromalite record of the western United States is quite limited, especially in contrast to the Triassic and Cretaceous records of the same region. Indeed, there are only a handful of well documented vertebrate bromalites from the Jurassic strata of the western USA, including: (1) coprolites from the non- marine Early Jurassic Glen Canyon Group; (2) consumulites and evisceralites from the Middle Jurassic Todilto and Sundance formations; and (3) consumulites, putative coprolites and pseudobromalites from the nonmarine Upper Jurassic Morrison Formation. Early Jurassic red beds are notably less fossiliferous than those of the Triassic (e.g., contrast the fossil record of the Chinle and Glen Canyon groups). The Middle Jurassic of the region includes several eolianites and sabkha-like deposits representing environments that preserve few bromalites. The Upper Jurassic Morrison Formation contains abundant vertebrate body fossils and many tracks but very few bromalites in contrast to many broadly similar fluvial deposits of Triassic and Cretaceous age in the same region. The global bromalite record also appears to be depauperate in the Jurassic, with a few exceptions such as marine shales and lithographic limestones in Europe (e.g., Lower Jurassic of England, Upper Jurassic Solnhofen Limestone of Bavaria). This relative lack of a global Jurassic bromalite record may in part be more a result of a lack of collection and study.

  • The Benefits of Commercial Fossil Sales to 21St Century Paleontology
    Palaeontologia Electronica http://palaeo-electronica.org The benefits of commercial fossil sales to 21st century paleontology Peter L. Larson and Donna Russell The luckiest people on this planet are the ones that have also made their passion their career. This is equally true for vertebrate paleontologists and commercial fossil dealers. We have other things in common as well. We all agree that fossils are import- ant. We agree that it is our responsibility to educate the public about fossils. And we agree that scientifically important specimens should be in museums. Fossils have been collected, bartered, bought and sold for thousands of years (Mayor 2000). Commercialism has remained a crucial and functionally key element of paleontology throughout its history. Although all facets of paleontology are permeated with continuing scientific contributions by commercial entities (Manning 2001), this essay will only reference a few of the more notable. In Europe, much of what we know about the Jurassic marine faunas and environ- ments of the Posidonia Shale Lagerstätten of Holzmaden (Germany), and the Blue Lias of Lyme Regis, Dorset (England) are based upon collections made by people who sold fossils. Mary Anning, an iconic person in the field of paleontology, is one of the more famous commercial collectors. Academics and curators at British institutions accepted Anning as a colleague, despite her lack of a formal degree or position at a university (McGowan 2001, Emling 2009). A congenial and civilized working relation- ship still exists today in England between commercial “professional” collectors and museum and university academics (Manning 2001). In Germany the government actively buys important specimens from private col- lectors (Rupert Wild, personal communication).

  • Iucn Summary Messel Pit Fossil Site (Germany)
    WORLD HERITAGE NOMINATION - IUCN SUMMARY MESSEL PIT FOSSIL SITE (GERMANY) Summary prepared by IUCNIWCMC (March 1995) based on the original documentation submitted by the Government of Germany and Land Hesse. This original and all documents presented in support of this nomination will be available for consultation at the meetings of the Bureau and the Committee. 1. LOCATION Located in the northern foothills of the Odenwalk, south of Frankfurt am Main, near the city of Darmstadt, in Land Hesse, Germany. 2. JURIDICAL DATA The Messel Pit is the property of Land Hesse and is therefore publicly owned. In 1991, the oil shale in the pit was declared a historical mineral resource, which makes it part of the cultural heritage as defined in the Heritage Protection Act (Denkmalschutzgesetz) of Land Hesse. The site is also recognised as a public monument by the Agreement of June 1992 on the Conduct of Palaeontological Excavations in Messel Pit with the Senckenberg Society for Nature Research, and the Agreement of December 1992 on the Scientific and Cultural Use of the Messel Pit Fossil Site with the Society for the Preservation of the Messel Pit Fossil Site. 3. IDENTIFICATION Messel Pit is approximately 1000 metres long (north to south) and 700 metres wide (east to west). The sediments of the Messel formation lie on deposits of 270 to 290 million year Old Red Sandstone and crystalline magmatic primary rock outcrops. The Eocene period basin had been hollowed out by faults in the earth's crust. The gradual subsidence of old sediments resulted in the formation of new sediments above them, and over time immense deposits accumulated.

  • 1 Excerpted by Permission from Chapter 9 of the Mistaken
    Excerpted by permission from Chapter 9 of The Mistaken Extinction, by Lowell Dingus and Timothy Rowe, New York, W. H. Freeman and Co., 1998, 332pp. Chapter 9 Living Dinosaurs? Now, let us be quick to clarify our query. We're not talking about dinosaurs still living hidden in the black waters of Loch Nesse or the darkest jungles of Africa. All but a few crackpots admit that sauropods and plesiosaurs are really extinct. But what about dinosaurs living in your own back yard? It seemed ridiculous. Or so we thought as we packed up our books and moved to Berkeley. When we arrived we were met by the prospect of living dinosaurs, and it seemed surprising to be confronted with the argument by members of our own department, instead of the street-life of Telegraph Avenue. Tyrannosaurus and Triceratops obviously did disappear at the end of the Cretaceous, our new colleagues conceded. Nonetheless, one lineage that descended from the ancestral dinosaur survived the impact and eruptions at the K-T boundary. Today, that lineage is represented by over 9,000 species of birds. Furthermore, if birds are living descendants of dinosaurs, isn't it incorrect to say that dinosaurs are extinct? What does it mean to say birds are dinosaurs? Proponents argued that newly discovered fossils demonstrated that dinosaurs were the ancestors of birds. In addition, new methods for reconstructing evolutionary history and establishing evolutionary 1 relationships were being developed. Applying these methods to the fossil record resurrected dinosaurs from extinction and in effect changed the course of the history of life.

    WEDNESDAY MORNING, NOVEMBER 3, 2004 ROMER PRIZE SESSION PLAZA BALLROOM A/B MODERATORS: RYOSUKE MOTANI AND RAYMOND ROGERS 8:00 Welcome 8:15 Beck, A.: THE ORIGINS OF MAMMALIAN LOCOMOTION: NEW METHODS FOR RECONSTRUCTING POSURE IN EXTINCT NON-MAMMALIAN SYNAPSIDS BECK, Allison, Univ. of Chicago, Chicago, IL The Synapsida, composed of living mammals and their extinct ancestors, are colloquially known as the ‘mammal-like reptiles.’ The extensive fossil record captures numerous transitional forms recording the transition from Permian, reptile-like pelycosaurs to primitive therians of the Triassic. A major part of this transition involved a change from a sprawling posture to one similar to the crouched posture of living small mammals such as the opossum. Despite our understanding of the postural endpoints, the question remains: What was the locomotory posture of taxa that are phylogenetically intermediate between pelycosaurs and modern mammals? Two major notions of postural change have been proposed, both supported by functional morphologic analyses and comparison to living mammals and reptiles. One suggests that intermediate taxa were capable of a dual-gait, much like modern crocodilians. The other outlines a series of increasingly upright intermediates. Neither hypothesis has been quantitatively evaluated. Here I set up a framework for interpreting function in extinct vertebrates, and apply it to reconstructing posture in extinct non-mammalian synapsids. Linear and angular measurements were taken on the limb and girdle bones of extant iguanian and varanid lizards, crocodilians, therian mammals and monotremes, and again on fossil synapsids. Multivariate and bivariate analyses were used to correlate suites of morphologic features with posture in the living forms.

Introduction Coming from the Schwabenalb (Swabian Alb) a visitor will discover in the Frankenalb (Franconian Alb) certain changes of lithology within the rocks of the Jurassic System. These changes are caused by the more marginal Situation of Franconia within the South German basin compared with the central position of Suebia; they are of various intensity during the different stages of the Jurassic System (Zeiss 1968a). Strong differences are developed in the Hettangian, Sinemurian, Lower Pliens- bachian, Upper Aalenian, Oxfordian, Kimmeridgian, and Tithonian stages. Above the Hettangian, these differences are concerning especially the Middle and Southern Frankenalb (see fig. 1). The Northern Frankenalb has had often closer relations to Suebia, documented by marls and clays as prevailing Sediments, in contrast to the predominating limestone deposits of the Middle and Southern Frankenalb. Of course the limits between these areas are not fixed strictly and may shift to some degree from time to time.
