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

Siphonotretoid brachiopods – a thorny problem [PDF]

open access: yesEstonian Journal of Earth Sciences, 2023
Siphonotretoids are presently placed within the subphylum Linguliformea and the class Lingulata, where they constitute a small, relatively short-lived superfamily and order, appearing near the end of the mid-Cambrian, with most forms becoming extinct ...

Brachiopod Molecular Phylogeny [PDF]

open access: yes, 2018
Analysis by parsimony, maximum likelihood and distance methods of newly determined nuclear-encoded SSU rRNA gene sequences from 23 species of articulate brachiopods, six inarticulate brachiopods, two phoronids and an ectoproct, together with other sequences from published and unpublished sources show that lophorates cluster with protostome, not ...

Biometric Relationship Between Growth Pattern and Biological Reproduction of a Living Fossil Benthic Brachiopods (Lingula anatina Lamarck, 1801) in Aceh Northern Shore

open access: yesIlmu Kelautan, 2023
Brachiopods are a group of ancient marine invertebrates that are still found today, so they are known as "living-fossil". The purpose of this study was to determine reproductive biology through sex ratio approach, gonad maturity stages, body mass weight ...

A multiproxy study of the Puhmu core section (Estonia, Upper Ordovician): consequences for stratigraphy and environmental interpretation [PDF]

open access: yesEstonian Journal of Earth Sciences, 2017
A multiproxy study of the Katian and Hirnantian in the Puhmu core in NE Estonia resulted in new data on chitinozoan and brachiopod biostratigraphy. Some mass occurrences of dasycladacean algae are tied to small early Katian ‘reefs’.

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,
