Biological evolution of the carbonate platform of the Taleh Zang Formation in Kermanshah region [PDF]

Journal of Stratigraphy and Sedimentology Researches, 2021
In this paper, the biological evolution of the carbonate platform of the Taleh Zang Formation with Paleocene age in the Kermanshah region has been investigated in two stages (time interval) concentrating on fossil debris (such as algae, corals, and ...

Renewal of planktonic foraminifera diversity after the Cretaceous Paleogene mass extinction by benthic colonizers

Nature Communications, 2022
Planktonic foraminifera are key to understanding paleoclimate and plankton evolution, but their origins are unclear. Here, the authors use a molecular clock to suggest that benthic foraminifera dispersed in plankton and renew planktonic foraminifera ...

Benthic Foraminifera of the Upper Jurassic Platform Carbonate Sequence in the Aydincik (Içel) Area, Central Taurides, S Turkey

Geologia Croatica, 2001
The Upper Jurassic sequence of the Aydincik (Içel) area consists of platform limestones which were deposited in a subtidal, restricted lagoon environment. Stratigraphic distribution of benthic foraminifera and calcareous algae, examined in thin-sections,

Biostratigraphy and paleoenvironment of Maastrichtian foraminiferal assemblages from a succession located NW of Tuxtla Gutiérrez, Chiapas (SE Mexico)

Revista Mexicana de Ciencias Geológicas, 2021
During the Maastrichtian, two lithostratigraphic units were deposited in the central Chiapas region; the Ocozocoautla and Angostura formations. The first unit crops out northwest of the city of Tuxtla Gutiérrez in central Chiapas.

Late Miocene to Early Pliocene benthic foraminifera from the Tasman Sea (Integrated Ocean Drilling Program Site U1506) [PDF]

Journal of Micropalaeontology
Modern and fossil benthic foraminifera have been widely documented from New Zealand, but detailed studies of material collected from drilling expeditions in the Tasman Sea are scarcer.

Automated identification of fossil benthic foraminifera from the Peruvian margin using convolutional neural networks [PDF]

Journal of Micropalaeontology
Benthic foraminifera tests preserved in marine sediments are well-established proxies for bottom-water dynamics, yet their minute size and high diversity demand laborious manual identification of hundreds of individuals to reconstruct subtle faunal ...

Compound‐specific isotope analysis of benthic foraminifer amino acids suggests microhabitat variability in rocky‐shore environments

Ecology and Evolution, 2018
The abundance and biomass of benthic foraminifera are high in intertidal rocky‐shore habitats. However, the availability of food to support their high biomass has been poorly studied in these habitats compared to those at seafloor covered by sediments ...

Landscape Mapping, Ichnological and Benthic Foraminifera Trends in a Deep-Water Gateway, Discovery Gap, NE Atlantic

Geosciences, 2021
Multidisciplinary studies have allowed us to describe the abiotic landscapes and, thus, reveal the ichnological and benthic foraminifera trends in a deep-water gateway.

Biogeochemical, sedimentological and dinoflagellate‐based reconstruction of the Holocene palaeoenvironment of the east Limfjord, Denmark

Boreas, EarlyView.
To assess how the eastern part of the Limfjord system has changed over the Holocene, relative to the wider Limfjord and western Baltic region, a sedimentary succession spanning c. 9600–150 cal. a BP was collected from Nibe Bredning, near Sebbersund, from a shallow coastal inlet along the eastern connection between the Limfjord and the Kattegat (north ...

Testing coir (coconut) fiber as a novel, biodegradable material for coral reef restoration: coir interactions with larval and juvenile corals

Restoration Ecology, EarlyView.
Abstract Introduction Coral populations have declined in recent decades, largely due to anthropogenic climate change. In response, coral restoration projects are being implemented, and rubble stabilization is one such approach. Rubble beds form when dead coral fragments accumulate on the seafloor and can be mobilized by water flow.
