The paleoecology and taphonomy of a Santonian-Campanian (Upper Cretaceous) dinosaur-bearing vertebrate locality from Bulgaria: a window into an underexplored part of the Late Cretaceous European Archipelago [PDF]

Swiss Journal of Palaeontology
The Upper Cretaceous European vertebrate fossil record has improved significantly in the past three decades but there still remain chronostratigraphic and geographic gaps, which obscure our understanding of the paleobiogeography and evolution within the ...
