The fossil record of parasites is limited thus far. A survey of the fossil record shows that some
modes of preservation show a higher potential for the preservation of parasitic remains or …

Traditional analyses of Early Phanerozoic marine diversity at the genus level show an
explosive radiation of marine life until the Late Ordovician, followed by a phase of erratic …

Parasites are ubiquitous in modern ecosystems, occupy one of the most successful life
modes, promote ecosystem stability, and, despite their typically diminutive size and lack of a …

Abstract During the Devonian Nekton Revolution, ammonoids show a progressive coiling of
their shell just like many other pelagic mollusk groups. These now extinct, externally shelled …

During the Palaeozoic, a diversification in modes of life occurred that included a wide range
of predators. Major macroecological events include the Cambrian Explosion (including the …

Mollusks in general and ammonoids in particular are known to display a sometimes
profound morphological intraspecific variability of their shell. Although this phenomenon is of …

Raised shell projections on the inner shell walls that form pits on the internal moulds of
Devonian ammonoids have been known for several decades. New specimens from Morocco …

Dendritic and/or rosetted microborings in calcareous and osteic skeletal substrates have a
diverse trace fossil record, spanning most of the Phanerozoic, whereas the ichnodiversity of …

During its Annual 2007 Meeting in Uzbekistan (BECKER 2009), SDS decided to revise the
base of the Emsian since the current GSSP in the Kitab Reserve lies much lower than …

A great number of new studies have been carried out on ammonoid embryonic development
in the last two decades. We focus here on novel developments and interpretations in the …
