Calpionellid and calcareous nannofossil evolution and calcification across Tithonian-Berriasian interval (Tethys Ocean). [PDF]

open access: yes, 2008
The Tithonian-Berriasian interval is characterized by the appearance of calpionellid and by a major calcareous nannofossil speciation episode: several genera and species first appear and evolve, showing an increase in diversity, abundance and ...

On the diversity of microfossils in the Bazhenov Horizon of Western Siberia (Late Jurassic–Early Cretaceous)

open access: yesGeoresursy
Paleontological remains from the Bazhenovo Horizon of Western Siberia (Tithonian–Berriasian) are represented by macro- and microfossils. The Horizon had a marine genesis and the basis of ecosystem of this paleobasin composed of pelagic organisms ...

Sequence stratigraphy of the Oxfordian to Tithonian sediments (Baisakhi Formation) in the Jaisalmer Basin

open access: yes, 2015
The Oxfordian to Tithonian sediments deposited along the southern Tethyan margin exhibit very diverse sedimentary facies. The Jaisalmer Basin, situated along the northwestern margin of the Indian peninsula, is a good example of those preserving these ...

Diet of bird‐like troodontid dinosaurs: synthesis of a contentious clade

open access: yesBiological Reviews, Volume 101, Issue 4, Page 1760-1778, August 2026.
ABSTRACT Troodontidae is a clade of small‐to medium‐sized maniraptoran theropods that mainly lived in Laurasia (modern Asia, North America and Europe) during the Jurassic and Cretaceous periods and are believed to have had a variety of diets. The uniqueness of troodontid teeth suggests that they diverged from the typical flesh‐based diet of non‐avian ...

The early fossil record of Caturoidea (Halecomorphi: Amiiformes): biogeographic implications

open access: yesSwiss Journal of Palaeontology, 2023
Caturoidea is a clade of Mesozoic predatory ray-finned fishes which lived mainly in the Jurassic. The clade has a few records in the earliest Cretaceous and only two in the Triassic. Among the latter, specimen MPCA 632 Caturus sp.

Post‐Eocene 90° CCW Rotation of Sardinia‐South Corsica: Paleomagnetic Evidence From Permian‐Cretaceous Sediments of Nurra (NW Sardinia)

open access: yesTectonics, Volume 45, Issue 5, May 2026.
Abstract The paleomagnetism of Miocene calc‐alkaline volcanics and sediments from Sardinia has firmly showed that the Corsica‐Sardinia microplate rotated 50°–60° counterclockwise (CCW) with respect to Europe between 21 and 15 Ma, during its drift from the Provencal margin. However, Permian to Eocene rocks from central‐south Sardinia revealed higher (up
