Assessment of crystallographic influence on material properties of calcite brachiopods [PDF]

open access: yes, 2008
Calcium carbonate biominerals are frequently analysed in materials science due to their abundance, diversity and unique material properties. Aragonite nacre is intensively studied, but less information is available about the material properties of ...

Earliest ontogeny of early Cambrian acrotretoid brachiopods — first evidence for metamorphosis and its implications

open access: yesBMC Evolutionary Biology, 2018
Background Our understanding of the ontogeny of Palaeozoic brachiopods has changed significantly during the last two decades. However, the micromorphic acrotretoids have received relatively little attention, resulting in a poor knowledge of their ...

Climate Change and invasibility of the Antarctic benthos [PDF]

open access: yes, 2007
Benthic communities living in shallow-shelf habitats in Antarctica (<100-m depth) are archaic in their structure and function. Modern predators, including fast-moving, durophagous (skeleton-crushing) bony fish, sharks, and crabs, are rare or absent ...

Resource partitioning among brachiopods and bivalves at ancient hydrocarbon seeps: A hypothesis.

open access: yesPLoS ONE, 2019
Brachiopods were thought to have dominated deep-sea hydrothermal vents and hydrocarbon seeps for most of the Paleozoic and Mesozoic, and were believed to have been outcompeted and replaced by chemosymbiotic bivalves during the Late Cretaceous. But recent

An abrupt extinction in the Middle Permian (Capitanian) of the Boreal Realm (Spitsbergen) and its link to anoxia and acidification [PDF]

open access: yes, 2015
The controversial Capitanian (Middle Permian, 262 Ma) extinction event is only known from equatorial latitudes, and consequently its global extent is poorly resolved.
