Trilobites were the most successful clade of marine invertebrates during the Cambrian, as
highlighted by Sepkoski's Cambrian Evolutionary Fauna. After the Cambrian they were still …

Punctuated equilibria is a theory of evolution that suggests that species go through periods
of stability followed by sudden changes in phenotype. This theory has been debated for …

More than 100 m-long core sections from Western Lithuania (Baltic Basin), presenting an
almost continuous lower Silurian fine-grained siliciclastic organic matter-rich sedimentary …

The process of evolution and the structures it produces are best understood in the light of
hierarchy theory. The biota traditionally is described by either the genealogical Linnaean …

The upper Silurian, and especially Pridoli epoch is a critical interval for the understanding
the evolution of Earth's biota, since it witnessed series of powerful extinction events, global …

Abstract The Homerian to Ludfordian interval of the mid to late Silurian Period was a time of
significant changes in conodont communities, global climate, oceanographic patterns and …

The Earth's biota originated and developed to its current complex state through interacting
with multilevel physical forcing of our planet's climate and near and outer space …

The Ludlow epoch of the Silurian period was a time of significant geobiological
perturbations, the most significant being the mid-Ludfordian Lau Event and associated huge …

The Mulde event was one of several significant turnover events during the Silurian. This
event is mostly recognized in the fossil record of graptolites and conodonts, as well as stable …

Gothograptid retiolitines were distinctive in being one of the very few graptolite groups to
thrive through the late Wenlock extinction event that killed off most graptoloid species, and …
