The paleoecology, habitats, and stratigraphic range of the enigmatic cretaceous brachiopod peregrinella. [PDF]

open access: yesPLoS ONE, 2014
Modern and Cenozoic deep-sea hydrothermal-vent and methane-seep communities are dominated by large tubeworms, bivalves and gastropods. In contrast, many Early Cretaceous seep communities were dominated by the largest Mesozoic rhynchonellid brachiopod ...

Major biological events and fossil energy formation: On the development of energy science under the earth system framework

open access: yesPetroleum Exploration and Development, 2021
In geological history, one major life explosion and five mass extinction events occurred. These major biological and environmental events affected the evolution of the Earth ecosystem and controlled the formation of organic-rich strata.

Ecology and Evolution of Gall-Inducing Arthropods: The Pattern From the Terrestrial Fossil Record

open access: yesFrontiers in Ecology and Evolution, 2021
Insect and mite galls on land plants have a spotty but periodically rich and abundant fossil record of damage types (DTs), ichnotaxa, and informally described gall morphotypes.

Re-make, re-model: evolution and development of vertebrate cranial lateral lines. [PDF]

open access: yesBiol Rev Camb Philos Soc
ABSTRACT Lateral lines are placodally derived mechanosensory systems on the heads and trunks of many aquatic vertebrates. There is evidence of lateral lines in the earliest known vertebrate fossils, and they exist in organisms with widely different craniofacial morphologies – including the presence or absence of jaws, external or internal nostrils, and

MASS EXTINCTIONS AND CLADE EXTINCTIONS IN THE HISTORY OF BRACHIOPODS: BRIEF REVIEW AND A POST-PALEOZOIC CASE STUDY

open access: yesRivista Italiana di Paleontologia e Stratigrafia, 2019
Brachiopods are a key group in Phanerozoic marine diversity analyses for their excellent fossil record and distinctive evolutionary history. A genus-level survey of raw diversity trajectories allows the identification of the Brachiopod Big Five, episodes

Different order cyclicity of the Paleozoic reef formation

open access: yesИзвестия высших учебных заведений: Геология и разведка, 2019
There are five great cycles of reef formation in Paleozoic — Early Cambrian, Middle—Late Ordovician, Silu-rian—Devonian, Late Visean—Serpukhovian and Permian.

The fossil history of pseudoscorpions (Arachnida: Pseudoscorpiones) [PDF]

open access: yesFossil Record, 2017
Pseudoscorpions, given their resemblance to scorpions, have attracted human attention since the time of Aristotle, although they are much smaller and lack the sting and elongated tail. These arachnids have a long evolutionary history but their origins

Late Devonian red tide and mass extinction

open access: yesChinese Science Bulletin, 2002
Molecular stratigraphical, carbonate carbon isotopic, stratigraphical and paleontological data show that algal booming, eutrophication, anoxia, hypersalinity, positive δ13C excursion and biomass decreasing occurred in the offshore carbonate environments of the Frasnian-Famennian (F-F) transition, which hints that red tide might frequently take place in
