Type: Peer Reviewed Research Paper Journal: Journal of Asian Earth Sciences Year: 2013 Authors: Spencer ART, Wang S-J, Dunn MT, Hilton J. DOI 10.1016/j.jseaes.2013.07.030 Abstract: The medullosan pteridosperm ovule Stephanospermum Brongniartis a well-known component of Carboniferous aged coal-ball and siderite nodule floras from North America and Europe but also occurs in the Permian floras of Cathaysia […]


Combined methodologies for three-dimensional reconstruction of fossil plants preserved in siderite nodules: Stephanospermum braidwoodensis nov. sp. (Medullosales) from the Mazon Creek lagerstätte

Type: Peer Reviewed Research Paper Journal: Review of Palaeobotany and Palynology Year: 2013 Authors: Spencer ART, Hilton J, Sutton MD DOI 10.1016/j.revpalbo.2012.09.001 Abstract: A new species of Medullosan ovule from the Mazon Creek Carboniferous lagerstätte is documented using a novel combination of non-invasive X-Ray Micro-Tomography (XMT) and orientated precision sectioning based on the XMT results.  […]


A novel Carboniferous ovule elucidated through a combined methodology for three-dimensional reconstruction

Type Presentation Event PalAss Annual Meeting Authors Spencer ART, Hilton J, Suttton MD Date 2011 Abstract Plants fossilised within siderite nodules (FeCO3) are often three-dimensionally preserved – such as those from the Mazon Creek Carboniferous terrestrial lagerstätte. Fossils preserved in this way have historically been studied using single-surface observation or destructive  investigative methods such as […]


Anatomical 3d X-Ray Micro Tomography reconstructions: Maximising palaeobotanical data capture through preliminary non-destructive techniques

Type: Poster Event: The Palaeontological Association Annual Meeting Year: 2010 Authors: Spencer ART, Hilton J, Sutton MD. Abstract: Over the last decade Micro-CT and X-ray Micro Tomography (XMT) have become increasingly available as an investigative tool within physical sciences. Development of scanning technology has been matched by a rise in computational power and advances in software, reducing the […]


3D X-Ray Microtomography reconstructions: an important preliminary tool for palaeobotanists

Type: Poster Event: IPC3 Year: 2010 Authors: Spencer ART, Sutton MD Abstract: Over the last decade Micro-CT or X-ray Micro Tomography (XMT), has become increasingly available as an investigative tool. Development of scanning technology has been matched by a rise in computational power and advances in software, reducing the financial and time costs associated with […]
