      Two trilobite genera from the Davis Formation are named from the Old Lead Belt town of Elvins, Missouri: Colonial and solitary rugose and tabulate corals are common fossils in Mississippian strata. Paleozoic corals are really different from Stinchcomb, B. L. Paleoecology of two new species of Late Cambrian Hypseloconus. Stumm, E. C. / FOUR NEW SPECIES OF RUGOSE CORALS OF THE MIDDLE DEVONIAN GENUS Eridophyllum FROM NEW YORK, MICHIGAN AND OHIO, Contributions from the Museum of Paleontology, University of Michigan, Volume XII, No. 1, pb, pp. 1- 11, 2 plates, $ 5.

      Colonial rugose corals are common in western cratonal North America and in some of the allochthonous terranes, now amalgamated against its western margin. Throughout the Late Paleozoic, the coral faunas in these two different settings were significantly different. Comparisons of these faunas suggest that during the Mississippian the Alexander terrane probably was southwest of Arctic Alaska and.

      Corals divide into two subclasses, depending on the number of tentacles or lines of symmetry, and a series of orders corresponding to their exoskeleton: nematocyst type and mitochondrial genetic analysis. [1] [2] [4] Common coral typing crosses suborder/class boundaries. Hermatypic corals. Hermatypic corals in the order Scleractinia are stony corals that build reefs. Furthermore, two new species are described from the lower Miocene coral-associated limestones of Jamaica (Mithrax arawakum sp. nov. and Nemausa windsorae sp. nov.). Spurred by a recent revision of the subfamily, two known species from the same deposits are refigured and transferred to new genera: Mithrax donovani to Nemausa, and Mithrax unguis.

Preliminary data on Early and Middle Famennian (Late Devonian) rugose and tabulate corals from southern Belgium.

Kölner Forum für Geologie und Paläontologie, 19. A table listing all genera, their species numbers, and their bathymetric ranges are presented. The number of species in 19 oceanographic regions is mapped, the southwestern temperate Pacific (region including New Zealand) having the most species; species are cosmopolitan from the Arctic Circle to the Antarctic at depths from 0 to m.The Late Devonian extinction was one of five major extinction events in the history of life on Earth.

A major extinction, the Kellwasser event, occurred at the boundary that marks the beginning of the last phase of the Devonian period, the Famennian faunal stage (the Frasnian–Famennian boundary), about – million years ago. Overall, 19% of all families and 50% of all genera became.
