Centre for Palynology Newsletter 2
December 2012
Editorial
There was a very positive response to the first Centre for Palynology newsletter that was distributed
at the end of 2011. Consequently we will continue with this venture and a second edition has been
prepared for 2012. We hope you find it informative and an enjoyable read. Several alumni suggested
we initiate a ‘where are they now?’ feature. So if you would like to let colleagues know where you
now are and what you are doing, please send me a short paragraph that I can incorporate into the
next edition. Furthermore, we still need to track down various alumni. So if you know of someone
who is not on the distribution list please ask them to e-mail Charles Wellman with their details
([email protected]). In this issue we also have details of the upcoming Sheffield Geology
reunion that will take place in September (details on p.8). It is hoped that there will be a strong
contingent of palynologists at this event.

Birmingham) the external examiner. Doreen has returned to Tanzania and continues her work with
the Tanzanian Petroleum Development Corporation.
Brian Pedder was awarded a Ph.D. following his viva voce exam in December. Brian’s thesis was entitled “The Palynology of the Cambrian Nolichucky Shale at Thorn Hill, Tennessee, USA”. Brian’s research was funded by a NERC Open CASE award with the Natural History Museum, London. He was jointly supervised by Charles Wellman and Suzanne Feist-Burkhardt and Tim Potter at the NHM, London. Bernard Owens was internal examiner and Stewart Molyneux (British Geological Survey) the external examiner. Brian is now at Cambridge University working with Nick Butterfield and Thomas Harvey.
Janine Pendleton was awarded a Ph.D. following her viva voce exam in October. Janine’s thesis was
entitled “Palynological and palaeobotanical investigation of the Carboniferous deposits of the Bristol
Coalfield, UK: biostratigraphy, systematics and palaeoecology”. Janine’s research was funded by a
NERC CASE award with the National Museum Wales, Cardiff. She was jointly supervised by Charles
Wellman and Chris Cleal of the National Museum Wales. Bernard Owens was internal examiner and
Geoff Clayton (Trinity College Dublin) the external examiner. Janine is now working with Petrostrat.

Faisal Abuhmida is in the fourth and final year of his Ph.D. working on the palynology of the
Ordovician-Silurian of the Murzuk Basin, Libya. Faisal’s research is funded by the Libyan Petroleum
Institute and is supervised by Charles Wellman.
Simon Wallace is in the fourth and final year of his Ph.D. research working on the molecular genetics
of spore wall formation in the extant model plant (moss) Physcomitrella. He is jointly supervised by
Andy Fleming, Charles Wellman and David Beerling (all of the Dept. of Animal & Plant Sciences of the
University of Sheffield). Simon’s research forms an exciting collaboration between the palynological
and molecular research in the department.

Undergraduate teaching
This year six undergraduate students selected palaeontology for their Level 3 project topic. They
were given four extremely rare examples of tiny dispersed seeds recovered from coals from the
Forest of Dean coalfield. Ted Spinner discovered the seeds during his many hours of megaspore
picking from the Forest of Dean coals. The students examined them using light and scanning electron
microscopy before sectioning them for light microscope analysis of their gross structure and
transmission electron microscope analysis of their wall ultrastructure. This detailed analysis
confirmed the seed status of the fossils but the biological affinities of these tiny seeds remain
elusive.
There is a single Level 4 masters student studying palaeontology this year. Georgia Mills is
investigating the palynology of the fish ‘scales’ that occasionally turn up in palynological
preparations. She has taken complete thelodont fish, from the Silurian inliers of the Midland Valley
of Scotland, and gently dissolved them. Sure enough the organic lining of the denticles survive the
process intact and she is in the process of picking these and examining them using light, scanning
and transmission electron microscopy. The denticles are of variable morphology within the fish and
can be mapped onto denticle patterns documented by fish workers. Interestingly different fish taxa
can be identified based on their denticles and consequently they make a useful palaeobiological
tool. Furthermore, denticles are used in biostratigraphy, and thus their palynology may be of some
biostratigraphical value (although they tend to be fairly rare in standard palynological preparations).
The 2012 Palaeontological Association undergraduate prize was awarded to Kimberley Mullins.
Kimberley performed well in all of her undergraduate palaeontology modules. She performed
particularly well in her Level 3 project which involved a study of dispersed plant cuticles from
Permian deposits from Nottingham.

New Arrivals
Welcome to Dr Jenny Morris who has joined us on a three-year post. doc. Jenny is working on a
NERC standard grant “Evolutionary rise of deep-rooting forests and enhanced chemical weathering:
quantitative investigations into the current paradigm”. Jenny joins us from Cardiff University where
she undertook a Ph.D. and post. doc. working on Lower Devonian Lower Old Red Sandstone
palynology, palaeobotany and sedimentology. Jenny was supervised by Dianne Edwards and John
Richardson.

Laboratory News
There have been no major changes on the lab front with Steve Ellin continuing to run the lab and
train the incoming Ph.D. students.
Collections News
Following the clearance of Dainton Building the collections have been relocated to the Alfred Denny
Building. We are fortunate to have been given the large laboratory directly opposite Charles
Wellman’s office on C-floor. The room now houses all of the slide collections, the microscopes and
all of the theses. It is ideal for students and visitors who can peruse the theses in comfort and
examine and photograph relevant slides. We continue with the time consuming task of assembling
an electronic catalogue of all the stored materials.
Library news
The library has also been relocated to the Alfred Denny Building. It continues to grow and this year
saw a significant donation of reprints, books and theses from Rex Harland.

before we headed off into town to cap the evening off with a curry. It was a very successful and
enjoyable meeting and it was great to catch up with some old friends.
Fieldwork 2012
This year has seen a number of collecting trips. Sam Slater undertook a number of field trips to the
Middle Jurassic of the Yorkshire coast. As usual Charles Wellman spent a part of May in Scotland
collecting among the Old Red Sandstone, but including a brief meet with Paul Strother (Boston) to
continue their collaboration on the Torridonian. Later in May he visited the deserts of southwestern
USA with Willy Taylor (Wisconsin), Linda Graham (Wisconsin) and Louise Lewis (Storres) in a
continuation of their NERC-funded project examining terrestrial algae. Jenny Morris visited New York
State in September where she oversaw the drilling of a number of boreholes through Devonian
paleosol horizons.

Visitors
This year we had numerous visitors. Dave Shaw and Guy Harrington kindly spent time with Doreen
Mkuu providing some excellent advice on her Paleogene palynomorphs. We also had visits from
Dave Bodman, Awad Ibrahim, Hartmut Jaeger, Duncan McLean and Hendrik Nowak (a new Ph.D.
student with Thomas Servais in Lille) who made use of the library and collections. Bob Wagner,
former lecturer in the Geology Department, visited Sheffield and a lunch was held in his honour.
Many of Bob’s former Ph.D. students attended including Ted Spinner. Of course we also had
numerous visitors during the TMS Palynology Group meeting in Sheffield.

Geology Centenary Reunion
Alison Hunter, a former student in the geology department, is making preparations to celebrate the
centenary of geology at Sheffield University. Alison has established a website
[http://www.geologyatsheffield.co.uk] and is writing a book. The website is well worth a visit with
wonderful images of Sheffield geology fieldtrips past. Alison is also organizing a centenary reunion
and book launch to be held on 21st September 2013. Details of the reunion are to be found on the
website noted above. It is anticipated that lots of former palynology students will attend and it will
be a great opportunity to get together.
Outreach
Outreach is becoming an increasingly important element of university activities. The Centre
for Palynology was involved in two such events this year.
Janine Pendleton was instrumental in establishing the ‘Bolsover Dragonfly’ exhibition at
Cresswell Crags Museum. The exhibit centres on the famous giant dragonfly fossil
Erasipteron bolsoveri that was discovered at the colliery adjacent to the present day
museum site in the 1970s. Janine composed much of the text and helped the artist with the
panels for the exhibit. Several of us were invited to the VIP launch of the exhibition where
we met the miner who, remarkably, discovered the fossil as it passed by on an underground
conveyor belt removing spoil.

In 2011 the Department of Animal & Plant Sciences initiated an annual Christmas lecture for
Sheffield schools. Last year it was “Birds are amazing” by Tim Birkhead and this year Charles
Wellman was persuaded to present “Dinosaurs are dynamite”. The interactive talk had an
audience of over 1200 including 900+ school children. It featured a full scale reconstruction
of a Tyranosaurus head as well as live lizards and birds. Numerous palaeontological activities
were laid on by student helpers for the children to participate in after the talk. Guides
included Steph Wood dressed in a dinosaur suit:-
