An isolated supraorbital horncore collected from the Olmos Formation near Múzquiz is among the longest ever found, and records the presence in this area of a very large ceratopsid. The specimen probably pertains to a chasmosaurine, but differs significantly from…

The present contribution is the first instalment of a systematic revision of the Early Cretaceous (Barremian to Early Albian) corals of Puebla, Mexico. The coral fauna preserved in the Tehuacan region represents one of the most species rich associations of…

The up to 258 m thick, carbonate-siliciclastic Upper Cenomanian to Campanian rocks (Sadr unit), which crop out widely in the Nakhlak area of central Iran, consist of conglomerates, sandy limestones and dolostones, calcareous sandstones, sandy-argillaceous limestones and reefal limestones. The…

Although important dinosaur specimens have been recently described from Brazil, the theropod record in this county is still rather scarce, particularly from Cretaceous strata. Here we describe a complete right tibia (MCT 1783-R) from the Marilia Formation (Maastrichtian, Bauru Basin)…

Decapod crustacean specimens recently collected from new and previously reported localities of USA, Mexico, and Colombia, as well as a review of species of uncertain affinity, add important information to complete the descriptions and paleobiological knowledge of some Cretaceous primitive…

Fossil fish specimens from the Múzquiz Lagerstätte (Late Cretaceous) of northern México have been analysed using UV light-induced visible fluorescence microscopy, Particle-induced X-ray Emission (PIXE), X-Ray Diffraction (XRD), and Scanning Electron Microscopy (SEM). Specimens examined with UV light microscopy show…
