Mammalian lineages and the biostratigraphy and biochronology of Cenozoic faunas from the Riversleigh World Heritage Area, Australia

open access: yes, 2016
Lineage zones within nine contemporaneous mammalian lineages represented in the Cenozoic fossil vertebrate record from the Riversleigh World Heritage Area in northern Australia are used to resolve a series of faunal intervals from the Late Oligocene to ...

Rotation in the Southeastern Caribbean Arc (Grenadines) Accommodated by Back‐Arc Basin Inversion

open access: yesTectonics, Volume 45, Issue 4, April 2026.
Abstract The Caribbean tectonic plate is typically modeled as a rigid plate moving along discrete plate boundaries. Isolated exposures on islands have long shown that above the Lesser Antilles subduction zone, the plate experienced contractional, strike‐slip, and extensional deformation, but the importance of this deformation remained long unknown ...

Paleocene orthophragminids from the Lakadong Limestone, Mawmluh Quarry section, Meghalaya (Shillong, NE India). Implications for the regional geology and paleobiogeography [PDF]

open access: yes, 2018
The late Paleocene orthophragminids, hitherto poorly known from the Himalayan foreland basins, are studied from the Lakadong Limestone in Meghalaya, northeastern India, in order to establish a systematic, biostratigraphic, and paleobiogeographical ...

Upper Cretaceous planktic foraminiferal biostratigraphy

open access: yes, 2017
A high-resolution biostratigraphical zonation based on planktic foraminifera is developed for the Upper Cretaceous. It consists of twenty-five biozones defined with the aid of serial and coiled planktic foraminiferal taxa and presents the highest ...

Toward a Robust Plio‐Pleistocene Chronostratigraphy for ODP Site 762

open access: yesGeophysical Research Letters, 2020
The advent of rapidly acquired proxy records provides paleoceanographers and paleoclimatologists with a wealth of high‐resolution data. These data are a boon for the community, as they enable millennial or even submillennial scale interpretation of past ...
