Lithological Section and Biostratigraphy of the Gosheim Formation in Its Type Area (Lower Bajocian, Swabian Alb, SW Germany)
Palaeodiversity 8: 31–69; Stuttgart 30 December 2015. 31 Lithological section and biostratigraphy of the Gosheim Formation in its type area (Lower Bajocian, Swabian Alb, SW Germany) VOLKER DIETZE, NORBERT WANNENMACHER, MATTHIAS FRANZ & GÜNTER SCHWEIGERT Abstract A temporary section of the Lower Bajocian in the vicinity of Gosheim (W Swabian Alb, Germany) exposed the higher part of the ferruginous Humphriesioolith and the marly Blagdenischichten. The Humphriesioolith Member at the base and the overlying Blagdenischichten Member are combined in the herein newly introduced Gosheim Formation. Biostratigraphically, the section studied ranges from the Romani up to the Blagdeni subzones of the Humphriesianum Zone. Within this section we analyzed the ammonite faunas and recognized one ammonite fau- nal horizon of the Romani Subzone (romani horizon), three faunal horizons of the Humphriesianum Subzone (ger- villii/cycloides, mutabile, and umbilicum horizons) and a further, still unnamed horizon at the base of the Blagdeni Subzone.

His advice, support and patience were greatly appreciated. I deeply indebted to Mr. Klaus Banike of Gottingen, F. R. Germany for opening his home and his collection of concretions to me and also for his help and friendship. To Erhardt Trute and Family of Gerzen, F.R. Germany, I owe many thanks for their warm hospitality and assistance with my field work. Also Dr. Hans Jahnke of Georg-August University, Gottingen deserves thanks for his assistance and guidance. Jack Whorwood's photographic expertise was invaluable and Len Zwicker did an excellent job of preparing my thin sections. Also, Kathie Wright did a great job helping me prepare my figures. Lastly, I would like to thank all those people, they know who they are, from whom I begged and borrowed time, equipment and advice. iii ABSTRACT Study of the ecology of concretion and host sediment fossils from a shell bed in middle Bajocian clays of northwestern Germany indicates a predominantly epifaunal suspension-feeding community living on a firm mud bottom. -

The occurrence of calcium phosphate in the Mesozoic and Tertiary of Eastern England Albert Horton Abstract: Phosphate is a minor component of Mesozoic and Tertiary formations. It occurs widely scattered as nodules in argillaceous sediments, but is commonly concentrated in pebble beds and may be found replacing fossils. Phosphatic animal remains are rare and commonly occur immediately above major discontinuities, and fossilised animal faeces (coprolites) are extremely rare. Phosphatic pisoliths occur at only one horizon. In Eastern England calcium phosphate occurs as coprolites, bones, fossil replacements, ill-defined impregnations, nodules, pebbles, pisoliths and hardgrounds in Mesozoic and Tertiary strata. Many geologists (eg. Horton et al., 1974, p.35) have been guilty of imprecise use of these terms. Using local examples it is possible to obtain a clear understanding of the diverse origins of these deposits. Phosphorus occurs as a minor element in igneous rocks. Weathering and erosion result in transfer of the element within detrital grains and in solution. In marine environments, the phosphorus may be concentrated by physical, chemical and biological processes, Figure 1.

Coprolites The success of the early coprolite collectors may reflect the coprolites’ original large numbers and their Coprolites are trace fossils made up of faecal material. subsequent concentration by selective marine erosion Duffin (2009) records how in the 18th century a group with wave sorting of the dense material (Figs. 1 and of ornamented stones from the Chalk were thought to 2). -

The Marine Jurassic of Argentina: a Biostratigraphic Framework
326 by Alberto C. Riccardi The marine Jurassic of Argentina: a biostratigraphic framework Facultad de Ciencias Naturales y Museo, Universidad Nacional de La Plata, Paseo del Bosque s/n, 1900 La Plata, Argentina. Email: [email protected] In Argentina the best and most complete marine Juras- sic succession is exposed between 32° and 39° S, along a N-S belt roughly coincident with the border with Chile. Here all stages, except the Kimmeridgian, are represented by marine facies. Ammonites have provided a biostratigraphic framework to date and correlate lithostratigraphic units and sequences, to reconstruct the history of the marine fill, and allow the development of other palaeontological and geological studies. Recent studies on the systematics and/or biostratigra- phy of Andean ammonites have provided the basis for the presentation of a summary of the 45 ammonite zones of the Jurassic of west-central Argentina and to stress its significance in reconstructing the palaeogeographic evolution of that region. Introduction Jurassic rocks in Argentina are present over extensive areas (see Fig- ure 1) and include a large variety of marine and continental facies (see Riccardi et al., 1992). South of 39°S marine Jurassic consists of Pliensbachian-Lower Toarcian and uppermost Jurassic strata, repre- sented respectively in central and southern Patagonia. North of 39°S marine Jurassic is exposed along a N-S belt roughly coincident with the boundary between Argentina and Chile, up to 31°S where it becomes restricted to Chile. The marine Jurassic generally rests unconformably on Upper Triassic (west-central Argentina) and Upper Jurassic vulcanites (southern Patagonia) or on Upper Paleozoic (west-central Patago- nia). -
The Inferior Oolite at East Hill Quarry, Bradford Abbas, Dorset
The Inferior Oolite at East Hill Quarry, Bradford Abbas, Dorset ROBERT B. CHANDLER * and DAVID T.C. SOLE # * Riddlesdown High School, Purley, Surrey, CR81EX. # Home Farm, Lyme Road, Axminster, Devon, EX13 5SU. ABSTRACT The rocks of East Hill Quarry, Bradford Abbas are described in terms of beds and the faunas they contain. Comparison is made with S.S. Buckman's section, and for the first time in a century the Bradford Abbas Fossil Bed is described at this locality. The position of many important ammonites is given and their role in biostratigraphy highlighted. 1. Introduction: James Buckman (1814 - 1884) was first to arrive, after Bradford Abbas (ST 588145), on the Dorset/Somerset border resigning from a position as Professor of Botany and Geology east of Yeovil, lies on the outcrop of some of the most richly at the Royal Agricultural College, Cirencester. He moved to fossiliferous rocks in the world. It is a classic region for rocks Bradford Abbas in 1863 and was quick to acquaint himself of the Middle Jurassic which were exposed in the past in with the local geology and archaeology, in particular by numerous quarries and provided stone for building and making collections of ammonites. He was one of the founders road-making. The principal formation is the resistant of the Dorset NFC. He died in 1884 and was buried in the limestone of the Inferior Oolite Formation which rests on churchyard of the parish church in the village. Plate 1 shows a softer recessive sands of the Upper Lias. The limestones are recent photograph of his grave. -

Biogeography Exercise Name ______
EART101: Biogeography exercise Name ______________________________ The Cordilleran belt of western North America is composed of a collage of exotic terranes, microcontinental blocks that originated as island arcs in the Pacific and later were accreted to the continental margin. You would like to know the location of these terranes in the past. The table below contains presence/absence data for Early Jurassic ammonite species from three accreted terranes (Wrangellia W, Stikinia S, and Quesnellia Q) and from the North American continent (Boreal Craton BC and Sonomia So). The Boreal Craton represents higher-latitude, cooler-water faunas and Sonomia contained lower-latitude, warmer-water faunas. W S Q BC So Amaltheus X X X X Pleuroceras X Pseudoamaltheus X Becheiceras X X Arieticeras X X X X Fontanelliceras X Fuciniceras X X X Leptaleoceras X X Lioceratoides X X X Protogrammoceras X X X X X Aveyroniceras X X X Prodactylioceras X X X Reynesoceras X X Cymbites X Fanninoceras X X X X Phylloceras X 1. Calculate Jaccard similarity coefficients between each of the accreted terranes (W, S, and Q), and between the terranes and the two stable continent regions BC and So. The Jaccard coefficient is M/(N1+N2-M), where M is the number of taxa shared between the two regions, N1 is the number of taxa in region 1, and N2 is the number of taxa in region 2. Fill in your answers in the table below. W S Q BC So W S Q BC So 2. For each terrane, determine its approximate paleolatitude in the Early Jurassic.
