open access: yes, 2020
Endemic shallow-marine Cretaceous bivalves in the northeast Pacific region (NEP), extending from southwestern Alaska to the northern part of Baja California Sur, Mexico, are tabulated and discussed in detail for the first time.

Diversity patterns and palaeobiogeographical relationships of latest Devonian–Lower Carboniferous foraminifers from South China: What is global, what is local?

open access: yesJournal of Palaeogeography, 2014
During latest Devonian and early Carboniferous times, calcareous foraminifers were abundant, widely distributed, and showed the most rapid rate of evolution in the shallow-sea deposits. These factors, especially their fast phylogenetic changes, make them

Pliensbachian–Toarcian ostracod biogeography in NW Europe: Evidence for water mass structure evolution [PDF]

open access: yes, 2007
This paper examines the role played by palaeoceanographic and climatic conditions on the palaeobiogeography of the Pliensbachian–Toarcian ostracods (Early Jurassic) in the European Epicontinental Sea (EES).

The oldest post-Paleozoic (Ladinian, Triassic) brachiopods from the Betic Range, SE Spain [PDF]

open access: yesActa Palaeontologica Polonica, 2018
Triassic brachiopods from the Betic Range were unknown hitherto. Herein we describe the first brachiopod occurrences in the early Ladinian of this domain referable to a new genus and species Misunithyris goyi derived from three localities of the south ...

A critical revision of the fossil record, stratigraphy and diversity of the Neogene seal genus Monotherium (Carnivora, Phocidae) [PDF]

open access: yes, 2018
Historically, Monotherium had been one of the few genera of extinct Phocidae (true seals) that served as a wastebin taxon. Consequently, it did neither aid in understanding phylogenetic relationships of extinct Phocidae, nor in understanding seal ...

Revisiting the choristodere and stem-lepidosaur specimens of the Guimarota Beds (Kimmeridgian, Portugal): taxonomic implications [PDF]

open access: yesActa Palaeontologica Polonica
The Guimarota beds (Kimmeridgian, Portugal) constitute one of the richest microvertebrate assemblages for the Upper Jurassic, which include a diverse fauna of small reptiles.

Late Ordovician (Sandbian–Hirnantian) marine gastropods from the Argentine Precordillera: their biogeographical significance in a middle to high latitudinal setting [PDF]

open access: yesActa Palaeontologica Polonica
Gastropods from the Upper Ordovician of the Argentine Precordillera received less attention than other coeval marine invertebrates in this region. The present contribution supplies accurate taxonomic information recovering 10 gastropod genera which are ...

A new beaked whale record from the upper Miocene of Menorca, Balearic Islands, based on CT-scan analysis of limestone slabs [PDF]

open access: yesActa Palaeontologica Polonica, 2019
The finding of significant vertebrate remains inside commercial stone blocks is relatively rare. Here we describe a fossil cetacean skull discovered inside two slabs cut from a limestone block of Tortonian (i.e., early late Miocene) age from Menorca ...
