Tithonian ammonoid biostratigraphy in eastern Himalayan Tibet [PDF]
Geobios, 2004 Abstract The Tithonian and Lower Berriasian sediments in the eastern Himalayas of Tibet contain an extensive sequence of ammonoid fauna. New collections in situ through the Lanongla, Pure, Gucuo and Jiapeila sections have facilitated a major revision of the ammonoid assemblages.

Ausichicrinites zelenskyyi gen. et sp. nov., a first nearly complete feather star (Crinoidea) from the Upper Jurassic of Africa [PDF]
Royal Society Open Science, 2022 Fossil comatulids, referred to as feather stars, are mostly known from highly disarticulated specimens. A single isolated element (centrodorsal) has been the basis for taxonomic description of a vast majority of fossil comatulids.

Evolutionary Stability of the Shark Snout: Geometric Morphometrics of Ventral Facial Openings. [PDF]
Ann N Y Acad SciLandmark‐based geometric morphometrics of 453 shark species reveal that ventral head morphology is conserved across Selachii. Morphospace and ancestral reconstructions support strong phylogenetic control and limited divergence from ancestral conditions.

Biostratigraphic significance of calcareous dinocysts in the Tithonian of the Pieniny Klippen Belt (southern Poland) [PDF]
PeerJBiostratigraphic studies of pelagic Tithonian limestones in the Western Tethys are important for regional palaeoenvironmental reconstructions, particularly for determining the onset of the accumulation of Maiolica-type sediments which dominated Early ...

UPPER JURASSIC (TITHONIAN) AMMONITES FROM THE SPITI SHALES IN WESTERN ZANSKAR (NW HIMALAYAS)
Rivista Italiana di Paleontologia e Stratigrafia, 2017 A description is given of the ammonites collected during the Italian expedition to the Zanskar region of the NW Himalayas in 1984. The paleontological analysis is made in the context of a depositional and ecological model proposed for Spi ti Shales ...

Insect and Plant Diversity in Hot-Spring Ecosystems during the Jurassic-Cretaceous Boundary from Spain (Aguilar Fm., Palencia) [PDF]
Biology, 2022 Hydrothermal palaeoenvironments are very uncommon in Upper Jurassic and Lower Cretaceous deposits worldwide. We present new plant and insect remains from travertines formed during the Jurassic-Cretaceous boundary in northern Spain (Aguilar Fm., Palencia ...

Morphology and paleoecology of a hybodontiform with serrated teeth, Priohybodus arambourgi, from the Late Jurassic of northeastern Brazil. [PDF]
Anat Rec (Hoboken)Abstract Hybodontiformes was a diverse, successful, and important group of shark‐like chondrichthyans known from a variety of ecosystems. Some representatives of the order had a wide palaeogeographic distribution, as is the case with Priohybodus arambourgi. With a multicuspidate crown, P. arambourgi was the first hybodontiform to develop fully serrated
