A new genus and species (Decapoda: Brachyura: Prosopidae) is described from the lower Cretaceous Sebayashi Formation ofGunma Prefecture, Japan. It represents the second and oldest record of the Family Prosopidae from the North Pacific realm. A checklist of all known…

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 Early Cretaceous Scleractinian coral genus Holocystis Lonsdale, 1849 -first reported for southern England and for a long time believed to be restricted to this region- is easy to recognise but it is also rare. Abundant material from the Late…

A new plattenkalk facies locality with plants, invertebrates and vertebrates in laminar dolomitic limestones from the Albian of the lower part of the Sierra Madre Formation in central Chiapas is reported. The gastropod ?Perissoptera sp., one odonate-zygopteran nymph, one hemipteran-?belostomatid…

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)…

Four new species of decapods and one new species of isopod are described from the Barremian (Lower Cretaceous) Arida Formation in Wakayama Prefecture, Japan. Xanthosia sakoi new species (Brachyura, Etyidae) and Palaega yamadai new species (Isopoda, Cirolanidae) represents the first…

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…

A small assemblage of Maastrichtian ammonoids was collected at El Zancudo, south of Nuevo Laredo, Mexico, on the border with Texas. They are preserved as goethitic internal moulds of the innermost whorls. Nine taxa are described in abbreviated form. Eight…
