Paleontology: A New Burgess Shale Fauna
نویسنده
چکیده
A spectacular Cambrian soft bodied fauna some 40 km from Walcott's original Burgess Shale locality includes over 50 taxa, some 20% new to science. New anatomical evidence from this site will illuminate the evolution of early marine animals.

Preservation of early and Middle Cambrian soft-bodied arthropods from the Pioche Shale, Nevada, USA
a r t i c l e i n f o The Early–Middle Cambrian Pioche Shale of Lincoln County, Nevada preserves a diverse array of soft-bodied ecdysozoans that are well-known from the Burgess Shale soft-bodied fauna of British Columbia, Canada. At Pioche certain genera occur both above and below the Middle Cambrian boundary, allowing a comparison of the nature of their preservation across this interval. In or...

Forty two Paleocene benthic foraminiferal species of the Midway Formation in the Gulf Coastal Plain of Texas, USA were firstly investigated by Plummer (1927), and its paleogeographic distribution in some other countries in the Tethyan province were recorded: North America (USA, Mexico), South America (Argentina), Europe (North Sea Basin, Spain, France, Italy, Czech Republic, Bulgaria), North Af...
متن کاملBurgess Shale - Type Preservation and Its Distribution in Space and Time
—Burgess Shale-type fossil assemblages provide a unique record of animal life in the immediate aftermath of the so-called “Cambrian explosion.” While most soft-bodied faunas in the rock record were conserved by mineral replication of soft tissues, Burgess Shale-type preservation involved the conservation of whole assemblages of soft-bodied animals as primary carbonaceous remains, often preserve...
متن کاملMiddle Cambrian Arthropods from Utah
The Middle Cambrian Spence Shale Member (Langston Formation) and Wheeler and Marjum Formations of Utah are known to contain a diverse soft-bodied fauna, but important new paleontological material continues to be uncovered from these strata. New specimens of anomalocaridids include the largest and smallest near complete examples yet reported from Utah. New material of stem group arthropods inclu...
متن کاملSkimming the surface with Burgess Shale arthropod locomotion.
The first arthropod trackways are described from the Middle Cambrian Burgess Shale Formation of Canada. Trace fossils, including trackways, provide a rich source of biological and ecological information, including direct evidence of behaviour not commonly available from body fossils alone. The discovery of large arthropod trackways is unique for Burgess Shale-type deposits. Trackway dimensions ...
