... assemblage contains eight new soft-bodied taxa, including the anomalocaridid Stanleycaris hirpex n. gen., n. sp. (new genus, new species). Nektonic or nektobenthic predators represent the most diverse group, whereas in relative abundance, the assemblage is dominated by typical Cambrian shelly benthic taxa...

...), and Bathurst Island includes 22 species assigned to 21 genera. Many of these taxa are endemic to Arctic Canada. Each collection of brachiopods is typically dominated by only one or two taxa. Cluster analysis, based on binary data, shows that the brachiopods can be divided into an Atrypa – Elythyna community...

..., it is difficult to refer these disarticulated sponge spicules to existing or to new taxa. However, representatives of demosponges and hexactinellids are recognized. While marked differences are noted between older and younger lithistid dendroclones, for example, spicule form in these Middle Ordovician specimens...

The up-to-date chronostratigraphic subdivision of the Tournaisian and Viséan is not limited to Belgium and the surrounding areas. It can be applied through Eurasia as far as South China. The Belgian units could therefore be the basis...

... affinities of Namacalathus are uncertain, although preserved morphology is consistent with a cnidarian-like bodyplan. In general aspect, these fossils resemble some of the unmineralized, radially symmetric taxa found in contemporaneous sandstones and shales, but do not appear to be closely related...

Hence, Gudman reefs are stromatolite-rich examples of a larger class of microbialite-dominated Phanerozoic reefs...

... to assume quite low δ 18 O sw values (∼ -3‰) to bring our temperature estimates in line with modern tropical temperatures. Additional variables such as diagenetic overprints and ecology of the taxa analyzed can influence δ 18 O values independent of climate, but we argue that these variables could...

Within each 1 m vertical interval, each taxon was recorded as rare (1–2 specimens), common (3–15 specimens), or abundant (>15 specimens). Taxa were identified to the finest taxonomic resolution possible, which varied...

Brackish water within estuaries and other humid, marginal marine embayments may also contain a relatively depauperate benthic fauna, but because many taxa are uniquely adapted to variably brackish conditions (e.g., Fürsich 1993 ), brackish water alone is usually insufficient to exclude benthic...
