New Findings of Foraminifers and Age Correction of Callovian (Middle Jurassic) Marine Deposits of the Western Caucasus

Journal of Marine Science and Engineering
A comprehensive understanding of Callovian (Middle Jurassic, Mesozoic) sedimentation and paleogeography requires examination of marine deposits of this stage across multiple geological domains on Earth.

MIDDLE JURASSIC-LOWER CRETACEOUS BIOSTRATIGRAPHY IN THE CENTRAL PONTIDES (TURKEY): REMARKS ON PALEOGEOGRAPHY AND TECTONIC EVOLUTION

Rivista Italiana di Paleontologia e Stratigrafia, 1998
The deposition of Jurassic-Lower Cretaceous carbonates in the Pontides was controlled mainly by the evolution of an Atlantic-type continental margin in the Tethys.

Parasitism in Jurassic belemnites: examples from the upper Callovian of southern Poland

Acta Palaeontologica Polonica
Deformation in specimens of Hibolithes hastatus and Rhopaloteuthis spp. are documented from the upper Callovian Lamberti Zone of the Ogrodzieniec quarry, southern Poland.

A new caridean shrimp fossil with exceptionally preserved organs from the Middle Jurassic of La Voulte-sur-Rhône, France

Acta Palaeontologica Polonica
We used propagation phase contrast synchrotron X-ray micro-computed tomography (PPC-SRμCT) on an exceptionally preserved fossil caridean from the Callovian of the La Voulte-sur-Rhône Konservat-Lagerstätte.

CALCAREOUS NANNOFOSSIL BIOSTRATIGRAPHY OF UPPER CALLOVIAN-LOWER BERRIASIAN SUCCESSIONS FROM THE SOUTHERN ALPS, NORTH ITALY

Rivista Italiana di Paleontologia e Stratigrafia, 2010
Calcareous nannofossil biostratigraphy was investigated in uppermost Callovian-lower Berriasian sections from Southern Alps, previously detected through magnetostratigraphy, in order to achieve an integrated stratigraphic framework valid at low latitudes.

Plant remains from the Middle–Late Jurassic Daohugou site of the Yanliao Biota in Inner Mongolia, China

Acta Palaeobotanica, 2017
A late Middle–early Late Jurassic fossil plant assemblage recently excavated from two Callovian– Oxfordian sites in the vicinity of the Daohugou fossil locality in eastern Inner Mongolia, China, was analysed in detail.

Trans-border (South-Eastern Serbia/South-Western Bulgaria) correlations of the Jurassic sediments: The Getic and Supra-Getic units [PDF]

Geološki Anali Balkanskoga Poluostrva, 2008
The Getic and Supra-Getic are palaeogeographic units in SE Serbia and SW Bulgaria. Based on the presence (in Eastern) or absence (in Western) of Lower Jurassic marine deposits, the Getic is divided into Eastern and Western.

A perspective from the Mesozoic: Evolutionary changes of the mammalian skull and their influence on feeding efficiency and high‐frequency hearing

The Anatomical Record, Volume 309, Issue 9, Page 2315-2330, September 2026.
Abstract The complex evolutionary history behind modern mammalian chewing performance and hearing function is a result of several changes in the entire skeletomuscular system of the skull and lower jaw. Lately, exciting multifunctional 3D analytical methods and kinematic simulations of feeding functions in both modern and fossil mammals and their ...

‘The big chunky belemnite’: a new relict megateuthidid from the Oxfordian (Late Jurassic) of Wyoming, USA, and its place in the evolutionary history of the group

Papers in Palaeontology, Volume 12, Issue 5, September/October 2026.
Abstract We describe and discuss two finds of large and untypical belemnite rostra originating from the upper part of the Sundance Formation (Oxfordian) of Wyoming, USA. With a diameter reaching c. 60 mm at the anterior end, these rostra are the thickest known for belemnites so far.
