The Earliest Feathers from the Lower Cretaceous Dabeigou Formation of North Hebei: Implications for the Early Evolution of the Jehol Biota

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 ...

The marine conservation deposits of Monte San Giorgio (Switzerland, Italy): the prototype of Triassic black shale Lagerstätten

Swiss Journal of Palaeontology
Marine conservation deposits (‘Konservat-Lagerstätten’) are characterized by their mode of fossil preservation, faunal composition and sedimentary facies. Here, we review these characteristics with respect to the famous conservation deposit of the Besano
