Luke has been working with Professor Bo Wang at the Nanjing Institute of Geology and Palaeontology, Chinese Academy of Sciences to identify the potential for structural colours in Jurassic lepidopteran fossils. Their study aims to provide new insights into the evolution of colour producing nanostructures as well as scale morphology in insects.

A small selection of fossil insect wings of the order Neuroptera (lacewings) from the Jurassic of China. These wings, along with hundreds more, will be used by James in a morphometric analysis. The analysis will compare the different types of colour patterns preserved on the wings of the neuropteran fauna from the Jurassic of Daohugou, China.

Fresh from Culture Night, Maria jetted off to sunny Scarborough where she joined the PalAss team at the Annual Yorkshire Fossil Festival. As well as helping visitors to the PalAss stand make DIY fossil imprints and play the fossilization game, she took part in the Festival’s Soapbox Science event, armed with a trusty trilobite sidekick.

Chemical training in the lab. Giliane has set up a (safe) experiment for us to test whether acid should be placed into water, or should water be placed into acid. We ensured it was the correct way (acid into water!) before Tiffany tried it out!

Landmarks and Lifeforms: Linking science and art at the Limerick City Gallery of Art
Maria participated in a panel discussion at the opening of the new exhibition ‘Landmarks and Lifeforms’ by Irish artists Frieda Meaney and Danny Osbourne, chaired by Newstalk’s Éanna Ní Lamhna. The exhibition features prints and installations by Frieda focusing on evolution, change, and transformation, and lava sculptures and vessels by Danny. The panel discussion was very interactive, with lots of participation by the audience, and ranged in topic from origins of the Earth, climate change, and dinosaur evolution to creativity and the common methodical process that lies at the foundation of all scientific and artistic inquiry.

This is a histological section through a cuttlefish (Sepia officianalis) ink sack, the black-stained cells can be easily identified. Although it has been known for millennia that cuttlefish and other cephalopods produce ink, exactly how they produce melanin in their tissues is poorly known. Tim is currently looking into how and where melanosomes are produced in cephalopod tissue.

Tim’s current research aims to elucidate the nature and distribution of pigments in cephalopod molluscs. Using controlled sets of decay experiments, he is testing the robustness of these pigments to fossilization and what the preservation of these pigments could tell us about extinct taxa.

During a visit to his old lab in the physics department at the University of Exeter, Luke performed optical measurements to determine the angle-dependency of the circularly polarised reflectance from some of Giliane’s beetles.

Chris is dissecting the eye of a lamprey under the microscope, by separating the iris at the front of the eye from the choroid at the back. The long strand coming from the eye (as seen on the screen) is the lamprey’s optic nerve.

Maria was invited to give the first Quercus lecture of 2017, titled ‘Beyond the lab: making science accessible to all’. UCC’s Quercus students are recognised as some of the most talented in the university; the the Quercus Talented Students’ Programme aims to support and promote excellence in academia, sport, creative and performing arts, active citizenship and innovation/entrepreneurship. The goal of the Quercus lecture series is to inspire students, and staff, by presenting thought-provoking lectures by some of UCC’s most inspiring academics. Please see here for a video of the talk.

Nidia’s first tumbling experiments are done, all dried up and ready to analyse. Only a *few* hours of picking through sediment ahead!
16 Jan 2017
Some of the palaeontology research group went to the BT Young Scientist competition during the weekend, where we displayed our own exhibit “Walk Like A Dinosaur”. This project was created by palaeontologists in UCC’s School of BEES, UCC’s School of Engineering and UCC’s Department of Computer Science. A sensor was attached to the legs of visitors to our stand, which was used to estimate their speed whilst walking / running, and what species of dinosaur this was equivalent to! Each member of the public that participated received a personalized talk about their species. We also brought along some trilobite fossils, an ammonite fossil, a fossilized Megalodon tooth and a cast of Microraptor!
