 Bristol City Museum - Pliosaurus!

WhenSun, 13 August, 10:00 – 17:00

WhereBristol Museum & Art Gallery (map)

DescriptionTravel back in time 150 million years and dive into Bristol’s Jurassic seas. We dare you to come face to face with one very special creature – an eight metre long Pliosaurus called Doris. She’s the ultimate predator and you’ll be awestruck as you touch her skin, listen to her heartbeat and smell her disgusting breath! Then travel forward to the present day to find out more about this amazing beast. See her actual fossil – one of the world’s most complete – and play games to discover more about her life and death. All the family can have fun investigating the science that helped us bring her back to life. Ideal for children aged 3-11 years old. Discovered in Westbury, Wiltshire in 1994, our internationally significant specimen is the world’s only example of a new species of pliosaur – Pliosaurus carpenteri – and will be on public display for the first time. Pliosaurs are so big that it took ten years to prepare all the fossils that were found. Bristol Museum & Art Gallery opening times: Tue-Sun: 10am-5pm Closed Mondays except Bank Holiday Mondays and Mondays during Bristol school holidays: 10am-5pm

Monday 25th September

Dave Green - The Devonian Period WhenMon, 25 September, 19:30 – 21:30 WhereWynstones School, Stroud Road, Whaddon, Gloucester (map) DescriptionThe Devonian Period 419 to 358 million years ago, this period (whose existence was hotly disputed by Sedgwick and Murchison in the 1820s and 30s) saw the amalgamation of two parts of Britain (but strangely not including Devon!), the emergence of widespread land vegetation, closely followed by insects and terrestrial tetrapods. A major extinction, of disputed origin, wiped out a large proportion of life towards the end of the period. Half the world consisted of a vast ocean (Panthalassa), which, like the modern Pacific, was gradually being destroyed by subduction, in favour of the Rheic and PalaeoTethyian Oceans. Starts Mon 18th September for 10 weeks (not 16th or 23rd Oct), until 4th December Held at Wynstones School, Stroud Road, Whaddon, Gloucester from 7.30-9.30pm on Mondays. Cost £70 (including tea, coffee etc at breaktime!). Contact Dave Green, Joys Green Farm, Forge Hill, Lydbrook, Glos GL17 9QU Tel 01594 860858 davegeostudies@gmail.com

Bath Geol Soc Lecture - How did the largest animals ever fly?

WhenThu, 5 October, 19:15 – 20:45

WhereBath Royal Literary and Scientific Institution, 16 Queen Square, Bath (map)

DescriptionHow did the largest animals ever fly? Biomechanics and mass estimation in pterosaurs Liz Martin-Silverstone, Final Year PhD Student, Ocean and Earth Science, University of Southampton Pterosaurs were the first vertebrates to take to the skies, and the largest animals ever to achieve powered flight. The largest had wingspans rivalling small airplanes at 10-11m. The biggest birds today are nowhere near this size, with albatross wingspans of 3-4 m., and extinct birds may have reached up to 8 m. in size. Why were pterosaurs able to reach this great size? How were they able to fly? Exactly how heavy were these animals? With unique adaptations, pterosaurs were able to dominate the sky for over 150 million years.

The rock units and their relationships are superbly exposed along the spectacular Glamorgan Heritage Coast. Highlights include richly fossiliferous Carboniferous Limestone and Blue Lias (early Jurassic); marginal facies of the Mesozoic that developed close to upstanding areas of Carboniferous Limestone and are preserved adjacent to unconformities in the form of wadi breccias and rocky shoreline deposits; a variety of styles of unconformity; and impressive folds and faults. Meet at the car park at the south end of Ogmore-by-Sea village (SS 869 734) and later move to the car park at Dunraven Bay.

It is recommended that everyone should bring a drink with them. There will be numerous stops during the walk depending on questions/interest and these will involve looking at landscape and /or rocks. Booking not required, just turn up. Dogs allowed?: Well behaved dogs on a short lead welcome. Leader/organisation: Dave Green davegeostudies@gmail.com 01594 860858 or 07980 239991 on day.

WEGA Lecture - Dr. Heather Buss (Bristol University) WhenTue, 10 October, 19:30 – 21:00 WhereEarth Sciences Lecture Theatre, Wills Memorial Building, University of Bristol. (map) DescriptionCreating the critical zone: dissolving, fracturing, and eating rocks by Dr. Heather Buss, Bristol University The critical zone is the region of terrestrial Earth extending from the treetops to where rock begins to weather. It's critical because it provides many essentials that we need to survive on this planet - energy, nutrients, food, groundwater; it also mediates the release of toxins to the biosphere, controls water runoff and infiltration, affects the concentration of greenhouse gases in the atmosphere, and generates dust and sediments. The creation of the critical zone from solid rock is a complex but fascinating set of interlinked processes of chemical reactions, physical transport, fracturing, and metabolism. The feedbacks amongst these very different processes determine many of the characteristics of the critical zone, such as the shape of it, the depth of it, how fast it evolves, and the fertility of it. Because the critical zone is so critical, it's essential that we are able to preserve (or restore) its functions in the face of global and local environmental change. To do that, we need to understand exactly how these feedbacks work so that we can make accurate predictions of the consequences of environmental change as well as of our interventions. In this talk, I will discuss how these different processes are interlinked with a case study of spheroidal weathering in a tropical granitic rock, with extension to other lithologies and climate zones globally.

HYDROCK WILLIAM SMITH LECTURE WhenWed, 11 October, 19:00 – 20:00 WhereThe Great Hall Wills Memorial Building University of Bristol School of Earth Sciences Queens Road BS8 1RJ Bristol United Kingdom (map) Description Hydrock William Smith Lecture 2017 Following the success of the William Smith Bicentenary Lecture Series in October 2015, the University of Bristol School of Earth Sciences invites you to attend the inaugural Hydrock William Smith Lecture, a new series of annual public lectures on contemporary earth science topics sponsored by award-winning, Bristol-based engineering consultancy Hydrock (www.hydrock.com). The 2017 Hydrock William Smith Lecture will be: The Fingerprints of Sea Level Change in a Warming World Professor Jerry X. Mitrovica (Harvard University) Sea level changes are a particularly dramatic consequence of global warming and estimates of the average rise in sea level over the past decade are routinely reported in the media. However, such estimates obscure the fact that observed sea level changes vary dramatically around the globe. This lecture will describe the sources of this variability and focus on the unique patterns – or fingerprints – of sea level change that follow the melting of ice sheets and glaciers. In particular, sea level will actually fall within about 2000 km of a melting ice sheet and rise by increasing amounts at great distance. Thus, counterintuitive as it may seem, Bristolians should be far more concerned about the fate of the distant Antarctic Ice Sheet than the future of their neighbour, the ice sheet that now covers Greenland.
