This paper seeks to redress that situation and presents a synthesis of records of the 14 uppermost Triassic and Lower Jurassic from both onshore and offshore basins as well as descriBing 15 the sedimentological characteristics of the main lithostratigraphical units encountered. Existing data 16 have been supplemented with a re-examination and logging of some outcrops and the integration of 17 data from recent hydrocarbon exploration wells and boreholes. The Late Triassic Penarth Group and 18 Early Jurassic Lias Group can Be recognised across the RepuBlic of Ireland and Northern Ireland. In 19 some onshore basins, almost 600 m of strata are recorded, however in offshore Basins thicknesses in 20 excess of two kilometres for the Lower Jurassic have now been recognised, although little detailed 21 information is currently availaBle. The transition from the Triassic to the Jurassic was a period of 22 marked gloBal sea-level rise and climatic change (warming) and this is reflected in the 23 lithostratigraphical record of these sediments in the basins of Northern Ireland and offshore Basins 24 of the Republic of Ireland. -

Assessing the Record and Causes of Late Triassic Extinctions
Earth-Science Reviews 65 (2004) 103–139 www.elsevier.com/locate/earscirev Assessing the record and causes of Late Triassic extinctions L.H. Tannera,*, S.G. Lucasb, M.G. Chapmanc a Departments of Geography and Geoscience, Bloomsburg University, Bloomsburg, PA 17815, USA b New Mexico Museum of Natural History, 1801 Mountain Rd. N.W., Albuquerque, NM 87104, USA c Astrogeology Team, U.S. Geological Survey, 2255 N. Gemini Rd., Flagstaff, AZ 86001, USA Abstract Accelerated biotic turnover during the Late Triassic has led to the perception of an end-Triassic mass extinction event, now regarded as one of the ‘‘big five’’ extinctions. Close examination of the fossil record reveals that many groups thought to be affected severely by this event, such as ammonoids, bivalves and conodonts, instead were in decline throughout the Late Triassic, and that other groups were relatively unaffected or subject to only regional effects. Explanations for the biotic turnover have included both gradualistic and catastrophic mechanisms. Regression during the Rhaetian, with consequent habitat loss, is compatible with the disappearance of some marine faunal groups, but may be regional, not global in scale, and cannot explain apparent synchronous decline in the terrestrial realm. Gradual, widespread aridification of the Pangaean supercontinent could explain a decline in terrestrial diversity during the Late Triassic. Although evidence for an impact precisely at the boundary is lacking, the presence of impact structures with Late Triassic ages suggests the possibility of bolide impact-induced environmental degradation prior to the end-Triassic. Widespread eruptions of flood basalts of the Central Atlantic Magmatic Province (CAMP) were synchronous with or slightly postdate the system boundary; emissions of CO2 and SO2 during these eruptions were substantial, but the contradictory evidence for the environmental effects of outgassing of these lavas remains to be resolved. -
NEWSLETTER No. 102 MARCH 1998
Field Trips and Reports RGS Field Visit to Antrim, Northern Ireland – Saturday, September 15th to Saturday 22nd, 2012 This is a summary report specifically for the RGS Newsletter; a full, comprehensive report is being compiled separately and as well as being available to members will be part of the RGS exhibit at the Geologists Association Festival of Geology at UCL, London on Saturday November 10. Saturday, September 15th – the journey and Ballygally Twenty members of the RGS made their way to Gatwick to catch the 08.50 Flybe flight to Belfast. When the sun rose it was visible and we all felt it was a good omen for the week to come. We were met promptly at George Best Belfast City Airport by Kirkwood Coaches and the journey north up the east coast road was for many of us our first experience of Northern Ireland and what a pleasant joy it was. We soon arrived at The Halfway House Hotel, close to the beach and overlooking the Irish Sea to the hills of Galloway and what proved to be a friendly, excellent home for the week. We were met by Philip Doughty, who had originally planned to escort us all week but through unexpected ill health had had to restrict his involvement. He had very kindly found other local, expert volunteers to guide us around the planned sites on separate days and the itinerary had been adjusted to manage their availability. Philip whetted our appetite by introducing us to the overall geology of Antrim and how this would relate to the new itinerary, after which we trialed the Hotel’s bar and food menus to sustain our more natural appetites. -

Ammonite Diversity on the Jurassic
Ammonite Diversity Parkinsonia (pictured below) is perhaps the classic ammonite that you think of when imagining an Ammonite from the Jurassic Coast. However, there are many different types of ammonite so give you an idea of the variety, we have picked some of our Jurassic Coast favourites. Ammonites have a spiral shell divided into chambers. It could control its buoyancy in the water by filling the chambers with gas and water. The soft body of the ammonite only took up the last half whorl of the shell. Ammonites moved by sucking water through the mouth, pumping it over the gills, then squirting it out again. This propelled the animal through the water – backwards! Only the shells of ammonites have ever been found as fossils. How ammonites help us tell the time The ammonite species pictured right is one of the ‘zonal’ ammonites which help up work out the relative age of rocks. Ammonites evolved rapidly through time so if you find the same ammonite in two different locations, the rocks that they are found in must be the same age (unless the ammonite has been eroded and moved by rivers etc). So this fossil, Rasenia, gets its name from Market Rasen in Lincolnshire but this specimen was actually found 260 miles away near Ringstead, east of Weymouth. The rocks at both places are exactly the same age, dating back about 155 million years. Mariella rasenia Zonal fossils also help to tell the relative age of other fossils, such as the large marine reptiles. This is really important because it allows us to understand how they evolved through time. -
