Duxbury (1983) database of Cretaceous dinoflagellate cysts

About the database

Susanne Feist-Burkhardt, Andrew S. Henderson and Iona McLachlan

The database contains new, high quality colour images of Stanley Duxbury's (1983) type and figured specimens, from the Micropalaeontology Collections of the Natural History Museum. In addition to transmitted light images using Differential Interference Contrast, specimens were imaged using Confocal Laser Scanning Microscopy (CLSM). This novel technique was first used for morphological analysis and imaging of fossil palynological specimens by Feist-Burkhardt & Pross (1999). Confocal microscopy provides for extended focus images, red/green anaglyphs (please use red/green glasses to appreciate the 3D effect), 3D animations and animations of the image stack from specimens embedded in a microscope slide. For a detailed explanation and description of Confocal Laser Scanning Microscopy and its application to palynology please read the tutorial. All images and movies have been compressed for display on the Web. To play the movies you will need the QuickTime plug-in installed on your computer.

The original diagnoses and emended diagnoses provided are those given by Duxbury (1983) verbatim. All species illustrated in the database are cited by their original name and in their original spelling. Under the heading Note the editors give relevant information regarding changes in the taxonomic status of a taxon, subsequent to the publication of Duxbury (1983). For a full assessment of the taxonomic history of each taxon, emendations and synonymies see Williams et al (1998) or a subsequent edition. All cited literature refers to the references found in the same publication.
