Molluscs comprise the second largest phylum of animals (after arthropods), occurring in
virtually all habitats. Some are commercially important, a few are pests and some carry …

Background Despite the excellent fossil record of cephalopods, their early evolution is
poorly understood. Different, partly incompatible phylogenetic hypotheses have been …

Background During the Ordovician the global diversity increased dramatically at family,
genus and species levels. Partially the diversification is explained by an increased nutrient …

Orthoconic cephalopods are subordinate, but persistent, widespread and regionally
abundant components of Triassic marine ecosystems. Here, we describe unpublished …

Diversity evolution of 197 of the latest Ludlow–Lochkovian cephalopod species from
Bohemia (representing more that 70 percent of all species known worldwide) was analysed …

Cephalopods have their earliest occurrence in Late Cambrian shallow-water carbonates on
the North China Platform and rapidly dispersed across the globe within the latest Cambrian …

During the Ordovician Radiation cephalopods expanded their habitat from the shallow
marine environments of the low latitudes to global occurrences in almost all marine …

Abstract The late Katian, Late Ordovician Boda Limestone of Dalarna, Sweden contains a
rich cephalopod assemblage. The assemblage consists of 61 species, of 31 genera …
