Bayesian analyses indicate bivalves did not drive the downfall of brachiopods following the Permian-Triassic mass extinction [PDF]

open access: yesNature Communications, 2023
Certain times of major biotic replacement have often been interpreted as broadly competitive, mediated by innovation in the succeeding clades. A classic example was the switch from brachiopods to bivalves as major seabed organisms following the Permian ...

The demise of large tropical brachiopods and the Mesozoic marine revolution [PDF]

open access: yesRoyal Society Open Science
Changes in predator–prey interactions are often implicated as drivers of major evolutionary change. A prominent example is the dramatic changes in shallow marine assemblages during the Mesozoic Marine Revolution (MMR) when major clades, including ...

Combining soft-bodied and three-dimensional fossils to reveal evolutionary modifications in early lingulellotretid brachiopods [PDF]

open access: yesCommunications Biology
Living lingulide brachiopods are traditionally recognised as representatives of evolutionary conservatism, showing little change in general-morphology from their Cambrian ancestors.

LATE CARBONIFEROUS BRACHIOPODS FROM KARAKORUM, PAKISTAN

open access: yesRivista Italiana di Paleontologia e Stratigrafia, 1999
Carboniferous rocks from North Karakorum display sharp lateral variations in lithology and thickness suggesting accumulation in half-grabens during continental rifting between the Karakorum block and northern Gondwana. Different Carboniferous successions,

Marine Anoxia and Ocean Acidification During the End‐Permian Extinction

open access: yesGeophysical Monograph Series, Page 325-340., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Parasite-induced shell damage in brachiopod Porambonites (Porambonites) laticaudata from the Late Ordovician (Sandbian) of Estonia [PDF]

open access: yesEstonian Journal of Earth Sciences, 2023
A new type of shell damage has been described in Ordovician brachiopods in Porambonites (Porambonites) laticaudata. There is a pair of small pits with somewhat different outline in the shell surface at the anterior commissure of the brachiopod.

Paleoecology of the first Devonian-like sclerobiont association on Permian brachiopods from southeastern Mexico [PDF]

open access: yesActa Palaeontologica Polonica, 2021
This paper describes a sclerobiont association from the Paso Hondo Formation (Roadian, middle Permian), Chiapas, Mexico. Different marine invertebrates such as hederelloids, microconchids, bryozoans, and crinoids (represented by holdfasts) encrusted ...
