From: Journal of Paleontology | Date: July 1, 2003| Author: Lieberman, Bruce S | Copyright information

ABSTRACT-A new Burgess Shale-type soft-bodied fauna crossing the Lower-Middle Cambrian boundary in the Comet Shale Member of the Pioche Formation in Lincoln County, Nevada, contains common remains of soft-bodied ecdysozoan taxa. These fossils provide important new information about the nature and variety of Cambrian soft-bodied organisms. Arthropod taxa include one species of Canadaspis Novozhilov in Orlov, 1960, one species of ?Perspicaris Briggs, 1977, three species of Tuzoia Walcott, 1912,...

Tragedy found in Cambrian carnival. (evidence of mass extinction of animals) (Brief Article)
Science News ; Paleontologists have come to view the early Cambrian period as an evoluntionary field day -- a time when the first complex animals exploded onto the scene, filling the seas with a rich assortment of life. But new research reveals that a wave of extinctions may have hit right in the middle of this
AN EARLY CAMBRIAN RADULA
Journal of Paleontology ; ABSTRACT- Microscopic teeth isolated from the early Cambrian Mahto Formation, Alberta, Canada, are identified as components of a molluscan radula, the oldest on record. Tooth-rows are polystichous and lack a medial rachidian tooth-column. Anterior-posterior differences in tooth-row morphology are
Crusty crustacean
Natural History ; Crustaceans are a Large and varied crew, with some 39,000 species Living today and many more known from their fossil remains. The oldest fossil crustaceans date back to the Late Cambrian Epoch, between 512 and 505 million years ago. Now a team of paleontologists has found a fossilized arthropod
