New early Paleocene (Danian) paguroids from deep-water coral/bryozoan mounds at Faxe, eastern Denmark

Geologija, 2020
During recent decades, decapod crustacean faunas from middle Danian (lower Paleocene) strata at Faxe (Sjælland, Denmark) have been studied in detail. However, paguroid anomurans have not yet been described formally.

Hindlimb morphology of Palaeotis suggests palaeognathous affinities of the Geranoididae and other “crane-like” birds from the Eocene of the Northern Hemisphere [PDF]

Acta Palaeontologica Polonica, 2019
The early/middle Eocene Palaeotis weigelti is a flightless bird, which occurs in the fossil localities Messel and Geiseltal (Germany). The species is assigned to the Palaeognathae and some authors considered it to be a stem group representative of the ...

A new species of Ampulicomorpha Ashmead from Eocene French amber, with a list of fossil and extant Embolemidae (Insecta: Hymenoptera) of the world

BSGF - Earth Sciences Bulletin, 2020
Embolemidae is a cosmopolitan but species-poor group of chrysidoid wasps with a scarce fossil record, despite a long evolutionary history since at least the Early Cretaceous. Here, the new species, Ampulicomorpha quesnoyensis sp. nov., is illustrated and

Oligocene deep-water agglutinated foraminifers at Site 985, Norwegian Basin, southern Norwegian Sea [PDF]

, 1999
The stratigraphic distribution of deep-water agglutinated foraminifers was examined using 50 samples from Ocean Drilling Program (ODP) Hole 985A, drilled on the gentle slope of the Iceland Plateau in the Norwegian Basin. A total of 40 species and generic

Reshaping the understanding of the paratethys using paleogeographic reconstructions and geochronology studies [PDF]

Geološki Anali Balkanskoga Poluostrva
The history of the Paratethys and its inhabiting organisms was profoundly influenced by its connections with the Global Ocean. As the sea‐straits linking Paratethys with the ocean expanded, they integrated the Paratethys with the global ocean, causing ...
