The First 40 Million Years of Planktonic Foraminifera
Geosciences, 2021 We provide a biochronology of Jurassic planktonic foramininfera, using first order linkage to ammonite and nannofossil stratigraphy and geochronology. This enigmatic and understudied group of microfossils occurred from middle Toarcian through Tithonian ...

Systematics and biostratigraphy of the Perisphinctoidea(Ammonoidea) across the Tithonian/Berriasian boundary in South East France [PDF]
, 2020 The present thesis documents and revises the systematics and biostratigraphy of the Perisphinctoidea (Ammonoidea) faunas across the Tithonian/Berriasian boundary from three basinal sections (i.e. Charens, Le Chouet and Les Combes) of eastern Drôme (South

Kimmeridgian-Tithonian sea-level fluctuations in the Uljanovsk-Saratov Basin (Russian Platform) [PDF]
, 2007 The Uljanovsk-Saratov Basin, located in the southeast of the Russian Platform, presents an intriguing record of the Kimmeridgian-Tithonian sea-level fluctuations. In the Late Jurassic, this basin was a trough within the Interior Russian Sea.

Integrative Zoology, EarlyView.This study reports two isolated feather fossils from the Lower Cretaceous Dabeigou Formation in northeastern China. Morphological analyses identified them as the earliest known feathered theropods (potentially including avian) in the Jehol Biota. This finding reveals a complex ecosystem at the dawn of the Jehol Biota, bridging the temporal and faunal ...
