The Lover Devonian Hunsrück Slate in western Germany is world-famous for its exceptionally preserved and beautiful fossils. What makes this Konservat-Lagerstätte so fascinating unique style of pyritization that has perfectly captured an entire ecosystem, from delicate echinoderms with soft tissues to the Lovecraftian Mimetaster.

in gene regulation. from many phyla is now making the use of alignments of hundreds or even thousands of genes a standard procedure. These studies have led to a widely accepted phylogeny of all animal phyla that has radically changed our views of animal evolution ( 3). Premolecular phylogenies generally envisaged a gradual increase in complexity from the earliest animals without a body cavity o...

Information on changes over time in the biodiversity and ecology of tropical systems is of increasing importance against the background of local, regional, and global dynamics. This study aimed to contribute with long-term data on the abundance fluctuations of two species of echinoderms from a tropical tidal flat. From February 1984 to December 1986, March 1985 to April 1987, and July 1994 to S...
