Organic-walled marine microplankton from the Barremian and Aptian of the North Sea Region - biostratigraphy and taxonomy - Part 4 - online 31 May Vol No. 2 posted Mar The dinoflagellates, acritarchs and tasmanitids are also sometimes referred to as "acid-insoluble or organic-walled microplankton" for the same reason. DINOFLAGELLATES Within the algal Division Pyrrhophyta (the dinoflagellates) are four classes: the Ebriophyceae, the Ellobiophyceae, the Desmophyceae and the Dinophyceae (Table I).Cited by: 3. Occasionally (and fortunately), circumstances and timing combine to allow an individual, almost singlehandedly, to generate a paradigm shift in his or her chosen field of inquiry. William R. (‘Bill’) Evitt (–) was such a person. During his career as a palaeontologist, Bill Evitt made lasting and profound contributions to the study of both dinoflagellates and trilobites. He had a Cited by: 6. My main field of expertise is Precambrian and Palaeozoic organic-walled microplankton (acritarchs, chitinozoans) and plant microfossils (cryptospores, spores triletes), in application to high-resolution biostratigraphy and subsurface correlation, palaeoenvironmental reconstructions, organic .
Since the production of three literature compilations in , and , further published contributions on Triassic, Jurassic and earliest Cretaceous (Berriasian) dinoflagellate cysts were issued between April and January , or have been discovered.

The metal content, particularly Fe, Cu, As, Al, Pb, Ba, Mo and Mn, of individual chitinozoans and/or bulk-rock samples increases markedly in the teratological interval (Fig. 3a).Fe, As and Mn concentrations in bulk-rock samples increase by an order of magnitude, for example, from c. 50, to c. , p.p.m. Fe, on cue with the appearance of oolitic-ferruginous beds in the Cited by: The present work attempts to study the distribution of the microfossils and their biostratigraphic implications for the Kurnool basin. It is the first ever detailed systematic palaeontological investigation of the organic-walled microfossils preserved in fine-grained siliciclastic sediments of the Owk Shale of the Kurnool Group, south : Yogmaya Shukla, Mukund Sharma, V.N. Sergeev.
Sphaeromorphic algal cysts, most probably of the prasinophyte Tasmanites, and acanthomorphic acritarch vesicles, most probably Solisphaeridium, occur in a single 20 cm thick bed of micritic limestone in the lower part of the Middle Devonian (Givetian) Tully Formation near Lock Haven, Pennsylvania. Specimens are composed of authigenic calcite and pyrite crystals about 5–10 µm in by: 2. Lower and Middle Devonian spores of north and central Vestspitsbergen. Palaeontology 8; pp. , 15 plts. h.t.
