Silicified Mississippian Brachiopods from Muhua, Southern China: Rhynchonellides, Athyridides, Spiriferides, Spiriferinides, and Terebratulides

Mississippian Discinid Brachiopods Attached to a Soft-bodied Organism

A concretion from the lower Mississippian Meadville Shale Member of the Cuyahoga Formation near Lodi, Ohio, preserves a population of Orbiculoidea newberryi Hall in life position, associated with what is interpreted to be an unidentified soft-bodied organism. The brachipods show a diffuse unimodal orientation, parallel to the axis of the "host" organism, in what was probably an upward direction...

Brachiopods from Late Jurassic-Early Cretaceous hydrocarbon seep deposits, central Spitsbergen, Svalbard.

Late Jurassic-Early Cretaceous (Late Volgian-latest Ryazanian) rhynchonellate brachiopods are described from eight out of 15 hydrocarbon seep deposits in the Slottsmøya Member of the Agardhfjellet Formation in the Janusfjellet to Knorringfjellet area, central Spitsbergen, Svalbard. The fauna comprises rhynchonellides, terebratulides (terebratuloids and loboidothyridoids) and a terebratellidine....

Silicified and phosphatized Tianzhushania, spheroidal microfossils of possible animal origin from the Neoproterozoic of South China

Comparative study of microfossils from two kinds of sediments: chert intercalations (studied in thin section) and phosphorite/phosphatic carbonate (in thin section and maceration), from the upper Neoproterozoic Doushantuo phospho− rites in the Weng’an area, Guizhou Province, South China, shows that the phosphatized Megasphaera ornata and the chert−preserved Tianzhushania tuberifera should be re...
