A Vendian-Cambrian Boundary Succession from the Northwestern Margin of the Siberian Platform: Stratigraphy, Palaeontology, Chemostratigraphy and Correlation
(Cambridge University Press, 1998)
Siberia contains several key reference sections for studies of biological and environmental evolution across the Proterozoic-Phanerozoic transition. The Platonovskaya Formation, exposed in the Turukhansk region of western ...
Late Cambrian Radiolaria from Hunan, China
(Society of Economic Paleontologists and Mineralogists, 1997)
Well-preserved polycystine radiolarians, representing a new species in the family Entactiniidae, were recovered from subtidal micrites and bioclastic micrites of the Upper Cambrian (<i>Glyptagnostus reticulatus</i> trilobite ...
Morphological Reconstruction of Miaohephyton Bifurcatum, a Possible Brown Alga from the Neoproterozoic Doushantuo Formation, South China
(The Paleontological Society, 1998)
On the basis of morphological and taphonomic study of a large sample population, <i>Miaohephyton bifurcatum</i> Steiner, emend. from the terminal Proterozoic Doushantuo Formation (600-550 Ma), South China, is interpreted ...
A Bangiophyte Red Alga from the Proterozoic of Arctic Canada
(American Association for the Advancement of Science, 1990)
Silicified peritidal carbonate rocks of the 1250- to 750-million-year-old Hunting Formation, Somerset Island, arctic Canada, contain fossils of well-preserved bangiophyte red algae. Morphological details, especially the ...
The Vendian Record of Sr and C Isotopic Variations in Seawater: Implications for Tectonics and Paleoclimate
New Sr and C isotopic data, both obtained on the same samples of marine carbonates, provide a relatively detailed record of isotopic variation in seawater through the latest Proterozoic and allow, for the first time, direct ...
Elso Sterrenberg Barghoorn, Jr. (June 15, 1915-January 22, 1984)
(American Philosophical Society, 1991)
Daughter of Time

A Martian Chronicle
(New York Academy of Sciences, 1998)
Paleobiology of the Mesoproterozoic-Neoproterozoic Transition: The Sukhaya Tunguska Formation, Turukhansk Uplift, Siberia
Silicified carbonates of the latest Mesoproterozoic Sukhaya Tunguska Formation, northwestern Siberia, contain abundant and diverse permineralized microfossils. Peritidal environments are dominated by microbial mats built ...
Neoproterozoic Fossils in Mesoproterozoic Rocks? Chemostratigraphic Resolution of a Biostratigraphic Conundrum from the North China Platform
Siliciclastic rocks of the Ruyang Group, southern Shanxi, and the broadly equivalent Gaoshanhe Group, Shaanxi, contain exceptionally well-preserved, large (empty set approximate to 150 mu m) acanthomorphic acritarchs ...
