A basal elasmosaurid plesiosaur from the upper Albian– lower Cenomanian? Cambridge Greensand

open access: yesActa Palaeontologica Polonica
An historical indeterminate elasmosaurid specimen CAMSM X50356 (CAMSM = Sedgwick Museum) collected during the 19th century is described. The specimen comes from the Cenomanian Cambridge Greensand although the possibility of an Albian–lower Cenomanian age

Palaeobathymetry of the Abderaz Formation using foraminifera, Iran [PDF]

open access: yes, 2009
Abderaz Formation at its type section with an age of Turonian-early Campanian and a thickness of 300 m contains light grey shale and marl. The study of the planktonic foraminifera in isolated form led to differentiate three morphotype groups.

Cenomanian rotaliids (Foraminiferida) from Oman and Morocco

open access: yesSwiss Journal of Palaeontology, 2013
The small rotaliids (Foraminiferida) found in Cenomanian rock thin sections of Oman and Morocco are diversified. A continuum of morphotypes is divided within 3 taxa described as subspecies of Rotorbinella mesogeensis Tronchetti 1981 from which they share many morphological characteristics.

Paleodistribution of Cercidiphyllaceae and Future Habitat Prediction for Cercidiphyllum japonicum Under Climate Change

open access: yesEcology and Evolution, Volume 16, Issue 1, January 2026.
Employing MaxEnt modeling, this research projects shifts in the potential suitable habitat range of Cercidiphyllum japonicum under climate change trajectories. Analysis identifies temperature and precipitation as dominant drivers governing habitat distribution, with models indicating significant range contraction throughout the forecast period ...

Microborings in mid Cretaceous fish teeth [PDF]

open access: yes, 1999
Fish teeth and other remains from the British Cretaceous contain abundant evidence for post-mortem colonization by endolithic organisms. The borings are here recognised as occurring in three morphotypes, including a flask-shaped form not previously ...

Large Benthic Foraminifera Biozonation of Mauddud Formation in Selected Section from Balad Oil Field, Central Iraq

open access: yesIraqi Geological Journal
Three subsurface sections Ba-1, Ba-4, and Ba-8, and sixty-five thin sections were examined to investigate the biostratigraphy of the Mauddud Formation (age Early Albian - Late Cenomanian) within the Balad Oil Field located in central Iraq.

Depositional sequences and ammonoid assemblages in the upper Cenomanian-lower Santonian of the Iberian Peninsula (Spain and Portugal) [PDF]

open access: yes, 2014
A clear relationship exists between eustatic sea-level rises and falls recorded as cyclical depositional sequences and ammonite faunas during the Cenomanian-Santonian in the Iberian and West Portuguese basins.

Study of planktonic morphotype of the Abderaz Formation at type section, Iran [PDF]

open access: yes, 2009
Abderaz Formation at its type section with an age of Turonian-Early Campanian and a thickness of 300 m contains light grey shale and marl. The study of the planktonic foraminifera in isolated form led to differentiate three morphotype groups.
