WESTERN AUSTRALIAN DIVISION
2015 Gibb Maitland Medal Nominations
The Gibb Maitland Medal is awarded by the Western Australia Division of the Geological Society of Australia in order to recognize individuals who have made substantial contributions to geoscience in Western Australia. It is named for Andrew Gibb Maitland, Government Geologist from 1896 to 1926, who established the Geological Survey of Western Australia. The Medal is usually awarded each year and nominations are now sought for the 2015 Gibb Maitland medallist.

Talk title: A Bizarre Crinoid from a Methane Seep in the Late South Cretaceous of South Dakota, USA
Speaker: Dr Aaron Hunter, Dept. of Applied Geology, Curtin University
Abstract: Despite a rich and varied record, Mesozoic stalked crinoids are relatively rare in the Western Interior Seaway of North America compared to those found in Northern Europe. A unique example of Mesozoic stalked crinoid is described from cold methane seeps (hydrocarbon seep mounds also called “tepee buttes”) from the Upper Cretaceous (upper Campanian) of the Northern Great Plains of the United States; the first crinoids to be described from such an environment. The Late Cretaceous Western Interior Seaway has never before yielded any identifiable stalked crinoid remains. Nevertheless, there have been significant studies on both free living and stalked crinoids from other locations in the Upper Cretaceous of North America that provide a good basis for comparison.
This distinct species is characterized by a tapering homeomorphic column with through-going tubuli, lacking any attachment disc. The arms are unbranched and pinnulate, with muscular and syzygialarticulations. The unique morphology of the column justifies the establishment of a separate family. A new suborder is also proposed as there exists no corresponding taxon within the Articulata that can accommodate all the characteristics of this new genus. This new crinoid shares many features with other members of the articulates, including bathycrinids, bourgueticrinids and guillecrinids within the Order Comatulida, as currently defined in the revised Treatise of Invertebrate Paleontology. Reconstructing the entire crinoid using hundreds of semi-articulated and disarticulated (well preserved) fossils, reveals a unique paleoecology and functional morphology specifically adapted to living within this hydrocarbon seep environment.
About the speaker: Aaron joined Curtin University as Senior Lecturer of Palaeontology and Biostratigraphy in 2013. He was recently a Visiting Fellow and now Life Member at the Clare Hall, University of Cambridge, UK, collaborating with the Sedgwick Museum of Earth Sciences. After completing his BSc in Geology from Kingston University, specialising in mineral deposits and petroleum geology, and his MSc in Palaeobiology at the University of Bristol, Aaron gained his PhD in echinoderm taphonomy and palaeoecology from the University of London (Birkbeck College & University College London) in 2006. Aaron has completed Postdoctoral Fellowships at the University of Burgundy, France (CNRS), University of Tokyo, Japan (Royal Society JSPS Fellow and JSPS Bridge Fellow) and University of Göttingen (DAAD), furthering his research into both fossil and extant echinoderms including crinoids (sea lilies) and asterozoans (starfish and brittle stars). In 2010 Aaron was appointed Senior Lecturer at the PETRONAS University of Technology, Malaysia where he established the Malaysian Centre of Palaeobiodiversity (MCPB) and was Deputy Director of the South East Asia Carbonate Research Laboratory (SEACARL), supervising MSc and PhD students and was course director for the undergraduate Palaeontology and Physical Geology courses. During this period he held a short term fellowship at NESCent, Duke University USA and was a visiting associate at the American Museum of Natural History.
