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.

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.

Computed tomography reveals multiple origins of extreme caudal vertebral pneumaticity in sauropod dinosaurs. [PDF]
J AnatHere, we present novel CT scan data of caudal vertebrae of six Middle–Late Jurassic sauropods, representing several eusauropod lineages. We synthesise these new data with a comprehensive critical appraisal of purported external and internal evidence for caudal vertebral PSP in Sauropodomorpha.

Systematic revision and evolution of the Tithonian family Chitinoidellidae Trejo, 1975
Carnets De Geologie, 2021 Several new genera and species of the family Chitinoidellidae Trejo, 1975, were erected by Pop (1997, 1998a, 1998b). Some of these taxa are justified, but others are inadequately defined, and require revision. I discuss herein the non-validity of some taxa and propose a new systematic classification and an evolutionary framework for the family ...

Tithonian-berriasian beds of dedine stream near Golubac [PDF]
Glasnik Srpskog geografskog drustva, 2007 The possibilities for stratigraphical precision between the Upper Jurassic and the Lower Cretaceous in pelagic development are considered for the locality of Dedine stream. Nearby the city of Golubac, is observed and described the profile that starts with Paleozoic schists which are overlained with Oxfordian/Cimeridgian limestones with cherts, then ...

A juvenile pleurosaurid (Lepidosauria: Rhynchocephalia) from the Tithonian of the Mörnsheim Formation, Germany. [PDF]
Anat Rec (Hoboken)Abstract Late Jurassic rhynchocephalians from the Solnhofen Archipelago have been known for almost two centuries. The number of specimens and taxa is constantly increasing, but little is known about the ontogeny of these animals. The well‐documented marine taxon Pleurosaurus

Endocranial anatomy of the earliest Cretaceous European neosuchian crocodyliform Pholidosaurus purbeckensis provides new evidence for the ecological evolution of Pholidosauridae. [PDF]
J AnatWe present new insights into the internal cranial anatomy of the neosuchian crocodyliform Pholidosaurus purbeckensis, based on CT‐scan data of material from the lowermost Cretaceous Purbeck Limestone Group, southern UK. From the study of the endocast, we obtained new information on the phylogeny and the ecological evolution of the Family ...

Geophysical Monograph Series, Page 169-190., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Towards a standard Tithonian to Valanginian calpionellid zonation of the Tethyan Realm [PDF]
Acta Geologica Polonica, 2013 Abstract Lakova, I. and Petrowa, S. 2013. Towards a standard Tithonian to Valanginian calpionellid zonation of the Tethyan Realm. Acta Geologica Polonica, 63 (2), 201-221. Warszawa. A calpionellid zonal scheme is proposed for the Tithonian through Valanginian pelagic carbonates of the Western Balkan Unit, based on the vertical ranges of 57 ...
