On the Cretaceous mangroves of Bahariya Oasis, Egypt [PDF]

open access: yesTaeckholmia, 2016
Petrified stems (rhizomes) of a fern are described from Late Cretaceous (Cenomanian)beds in Bahariya Oasis. The discovered stems are related to Paradoxopteris stromeriHirmer (fern rachii) and to Weichselia reticulata Stokes & Webb.

Pterosaur Tracks from the Upper Cretaceous Anacleto Formation (Neuquén Basin), Northern Patagonia, Argentina: Insights into Campanian Pterosaur Diversity in Gondwana

open access: yesDiversity, 2022
The Campanian Anacleto Formation holds an abundant and diverse ichnofossil and body-fossil vertebrate record. Despite the striking diversity of this record, pterosaur fossils had never been described from the unit.

New fossil lizard specimens from a poorly-known squamate assemblage in the Upper Cretaceous (Campanian) San Juan Basin, New Mexico, USA [PDF]

open access: yesPeerJ, 2020
Recent collection efforts in the upper Campanian (∼76-73.5 Ma) Fruitland and Kirtland formations of northwestern New Mexico have significantly increased the taxonomic diversity of lizards in this historically poorly understood squamate assemblage.

Campanian-Maestrichtian benthic foraminifera of DSDP Hole 78-543A

open access: yes, 1984
Foraminiferal assemblages in sediments from Hole 543A suggest that toward the end of the Cretaceous there was an oscillating carbonate compensation depth (CCD) in the western Central Atlantic. Changing assemblages of siliceous agglutinated and calcareous

The Campanian stage

open access: yes, 2016
The Campanian working party in Brussels did not wish to make a conclusive recommendation but there was a strong feeling that the base of the stage should be fixed at the extinction-level of the crinoid Marsupites. Other criteria discussed included ammonites, belemnites, foraminifera, calcareous nannofossils and magnetostratigraphy.
