Post-Paleozoic crinoid radiation in response to benthic predation preceded the Mesozoic marine revolution
TLDR
It is suggested that the appearance and subsequent evolutionary success of motile crinoids were related to benthic predation by post-Paleozoic echinoids with their stronger and more active feeding apparatus and that the predation-driven Mesozoic marine revolution started earlier than in other groups, perhaps soon after the end-Permian extinction.
Trends in shell fragmentation as evidence of mid-Paleozoic changes in marine predation
TLDR
The observed trend in shell fragmentation constitutes strong and independent confirmation of a recently suggested end-Devonian changeover in the primary method of fish predation from shearing to crushing.
Comment on “Palaeoenvironmental Control on Distribution of Crinoids in the Bathonian (Middle Jurassic) of England and France” by Aaron W. Hunter and Charlie J. Underwood
Aaron W. Hunter and Charlie J. Underwood in their article pub− lished in Acta Palaeontologica Polonica (Hunter and Under− wood 2009) present some interesting results regarding facies control on the
Putative Late Ordovician land plants.
TLDR
This work documents an Ordovician (Hirnantian, c. 445Ma) putative plant macrofossil assemblage found in mudstones of the uppermost Ordovicians Zalesie Formation dated by trilobites, brachiopods and palynomorphs.
Crinoids from Svalbard in the aftermath of the end-Permian mass extinction
The end−Permian mass extinction constituted a major event in the history of cri− noids. It led to the demise of the major Paleozoic crinoid groups including cladids, disparids, flexibles and
