Tweed Project presents at SVPCA 2014



Last week was the annual Symposium for VertebratePalaeontology and Comparative Anatomy, this time held in York. Jenny Clack and Tim Smithson were at the meeting and presented talks and posters on the project.

Tim presented on the latest chondrichthyan discoveries, with exciting new specimens changing what we know about the evolution of this group. Jenny presented on the new tetrapod discoveries from a range of sites, and discussed what this tells us about the evolution of tetrapods after the end Devonian mass extinction. The presentations were well received and attracted a lot of interested. It was a great opportunity of get together with other Tweed Project researchers and the wider vertebrate research community.

A Day In the Life, with TW:eed Project’s Becky Bennion


The TW:eed Project keeps on growing, with new volunteers, researchers and student projects!

Becky Bennion is an undergraduate at The University of Cambridge. She has recently started a summer placement at The University Museum of Comparative Zoology, Cambridge. She is working on Early Carboniferous sharks, with a special focus on the preparation of rock samples to reveal shark teeth and bones. Her work is helping to reveal some really exciting new fossils! I recently caught up with her to find out how she has been getting on and ask her some questions.

How did you become interested in the project?

I’ve been fascinated by fossils my entire life, and have spent a lot of my childhood collecting specimens from the beaches near Whitby where I live. This love of the natural world led me to Cambridge where I am currently an undergraduate studying Natural Sciences.
 

I really wanted to gain useful experience this summer with fossil preparation and analysis, so I asked Jenny Clack during a practical class if she had anything she could offer. To my surprise she said yes, and here I am!

What do you hope to achieve in your work placement this summer?

I hope to find some interesting specimens which will be of use to the project in the long term!
It’s incredibly exciting to be working with material which no one has looked at before.


What has been your most exciting discovery to date?

I was lucky enough to accompany the team for a week’s fieldwork in the Scottish borders at the end of June. Whilst there we visited a new locality and I spotted some pieces of bone sticking out of part of the cliff, which was incredibly exciting! Although there hasn't been time to analyse the specimen yet, I'm hoping it will be significant to the project.

My summer project itself consists of preparing rock samples with acid, then analysing the chondrichthyan (shark) fossils which remain. So far we have found hundreds of fragments of teeth and other bones, including a few unusual teeth which we weren't expecting!

Fantastic work Becky!
