Model for late Neogene deformation in Panama

Geology, 1990
Previous workers, mostly using earthquake data, have postulated both discrete faults and complex, diffuse zones for the Caribbean-Nazca plate boundary in Panama. We have better resolved the location and character of late Neogene plate-boundary structures by using satellite imagery and a compilation of existing geologic map data.

Late Neogene Lophophaenidae (Nassellaria, Radiolaria) from the eastern equatorial Pacific

Zootaxa, 2022
Lophophaenidae is a clade of polycystine radiolarians that was highly abundant and diverse in the Late Neogene–Recent eastern equatorial Pacific (EEP). Despite their importance in fossil plankton assemblages, lophophaenids have been neglected because of their generally small size, complex morphology, and weak taxonomic framework.

Late Neogene Radiolaria and Mediterranean Paleoenvironments

1985
Although widespread in Mediterranean Miocene sediments, radiolarians occur in only a small proportion of the Pliocene and Quaternary sediments of that region. The major factor responsible for their occurrence seems to be increased biological productivity.

Late Neogene to Quaternary contractional structures in Crete (Greece)

Tectonophysics, 2010
Abstract Based on geological and tectonic investigations carried out along an N–S coast-to-coast transect across central Crete, southern Aegean (Greece), new meso- and macro-structural data mainly collected from Neogene–Quaternary deposits are presented and discussed.

Late neogene history of the Pacific-Caribbean gateway

Journal of South American Earth Sciences, 1989
Abstract Planktic foraminiferal provinces of Caribbean DSDP Hole 502A and East Pacific DSDP Hole 503A have been analyzed and compared with benthic and planktic isotope records, carbonate, hiatus events, and sea level changes. Four major events are evident in the closure history of the Pacific-Caribbean gateway, at 6.2, 4.2, 2.4 and 1.8 Ma. The faunal

Glacigenic Sedimentation and Late Neogene Climate Pattern

1997
The East Greenland dip seismic section presented here is 70 km (≈ 40 mi) long and extends back 10 million years. The area is prograding with maximal advancement during low sea levels, roughly 50% to 100% greater than during high stands. Deposition generally has been greatest since 2.2 million years ago.

Late Neogene marine Ostracoda from Tjörnes, Iceland

Journal of Paleontology, 1991
On the western side of the Tjörnes Peninsula in northern Iceland exposures of fossiliferous marine sediments, basalts, and glacial tills record the climatic history of this region of the North Atlantic Ocean. Seventy-five marine ostracode species were recovered from the Pliocene Tjörnes sediments and Quaternary sediments known as the Breidavik beds ...

The hippo's tale: how the anatomy and physiology of Late Neogene Hexaprotodon shed light on Late Neogene environmental change

Quaternary International, 2004
Abstract Modern hippopotamuses are strongly dependent on permanent water because of the structure and properties of their skin, and because they forage on vegetation located close to watercourses. In the fossil record of Asia, the disappearance of hippopotamids (best represented by Hexaprotodon sivalensis) during the late Neogene and Pleistocene was ...

Evolutionary trends of tropical calcareous nannofossils in the late Neogene

Marine Micropaleontology, 1998
Abstract Examination of Middle–Late Miocene sediments recovered during ODP Leg 154 in western equatorial Atlantic has led to identification of evolutionary transitions in some groups of late Neogene calcareous nannofossils. Through analyses of high resolution samples (10-cm sample interval equivalent to average interval of 6 kyr) we were able to ...

Amphipoda from the Late Neogene of Shanxi, China

2021
Amphipods are extremely diverse malacostracan crustaceans that have conquered many environments from oceanic abysses to the terrestrial realm. Despite their impressive modern diversity and abundance, they are particularly rare in the fossil record. Herein, we describe the exceptionally preserved Gammaroidorum yooling sp. nov.
