A new fossil from the Eocene of Iran provides new insights regarding the evolution of the morphologically bizarre tube‐eye fish

Papers in Palaeontology, Volume 12, Issue 4, July/August 2026.
Abstract Stylephoriformes are a morphologically bizarre lineage of deep‐sea fishes, currently represented by a single extant species, Stylephorus chordatus, the so‐called tube‐eye fish. The phylogenetic relationships of the Stylephoriformes were extensively debated until recent genomic studies proposed a sister‐group relationship with the Gadiformes ...

Archaeal Tetraether Lipids as Tracers for Past Marine Environmental Change

Paleoceanography and Paleoclimatology, Volume 41, Issue 7, July 2026.
Abstract Archaea are single‐celled microorganisms that are abundant in marine environments and play a key role in the carbon and nitrogen cycles. Archaea can biosynthesize a wide variety of isoprenoid membrane lipids, including isoprenoid glycerol dibiphytanyl glycerol tetraethers (isoGDGTs).

Testing the extraction of past seawater Nd isotopic composition from North Atlantic deep sea sediments and foraminifera

Geochemistry, Geophysics, Geosystems, 2011
Neodymium isotopes provide a paleoceanographic proxy for past deep water circulation and local weathering changes and have been measured on various authigenic marine sediment components, including fish teeth, ferromanganese oxides extracted by acid ...

Vertical fluxes of coccolithophores and foraminifera and their contributions to CaCO3 flux off the coast of Ensenada, Mexico

Ciencias Marinas, 2017
Coccoliths and foraminifera fluxes and their contributions to CaCO3 were estimated by analyzing the material collected by a sediment trap installed in the area adjacent to Ensenada, Baja California (Mexico).

Age of the earliest transgressive event in the Krishna-Godavari Basin, India: evidence from dinoflagellate cysts and planktonic foraminifera biostratigraphy

Journal of Palaeogeography, 2020
A combined biostratigraphic study of dinoflagellate cysts and foraminifera was carried out on Early Cretaceous subsurface well cutting sediments from well A (DNG) (2800–2746 m depth) from the Krishna-Godavari Basin, India.

Marine ecology conditions at Weda Bay, North Maluku based on statistical analysis on distribution of recent foraminifera

MATEC Web of Conferences, 2017
Analysis of foraminifera in geology,usually being used to find the age of rocks/ sediments and depositional environment. In this study, recent foraminifera was used not only to determinethe sedimentary environment,but also to estimate the ecological ...

Preface: The planktonic foraminifera of the Jurassic

Swiss Journal of Palaeontology, 2017
Planktonic foraminifera originated in late Early Jurassic and, for reasons poorly understood, only underwent proliferation of species and geographic spreading from mid-Cretaceous onwards. Their evolutionary development in the oceans and adjacent seaways since early mid-Cretaceous has spurned a large volume of increasingly sophisticated literature ...

DISTRIBUCION DE LOS FORAMINIFEROS PLANCTONICOS DEL PLIOCENO EN LA PLATAFORMA CONTINENTAL DEL SW DE ESPANA

Rivista Italiana di Paleontologia e Stratigrafia, 2023
Planktonic Foraminifera assemblages from cores of a borehole are studied. Depth interval is from 380 m to 2300 m. The drill site is located in the continental shelf of "Golfo de Cadiz" (SW Spain).
