New Sauropod Trackways from the Middle Jurassic of Portugal [PDF]
Acta Palaeontologica Polonica, 2009 The Galinha tracksite reveals a sequence of Bajocian—Bathonian limestones belonging to the Serra de Aire Formation (West-Central Portugal) and is one of the few sites in the world where Middle Jurassic sauropod dinosaur tracks can be found. This tracksite is characterised by the presence of long, wide gauge sauropod trackways, the Middle Jurassic age ...

A triple junction in the Gulf of Mexico: Implications for deep petroleum exploration [PDF]
Geofísica Internacional, 2004 Mesozoic redbed and salt sequences have recently been dated using a palynostratigraphical method developed at the Mexican Petroleum Institute (IMP) since 1975. They represent the early Mesozoic marine transgression which formed the petroleum systems. The

Modeling the Middle Jurassic ocean circulation
Journal of Palaeogeography, 2015 AbstractWe present coupled ocean–sea-ice simulations of the Middle Jurassic (∼165 Ma) when Laurasia and Gondwana began drifting apart and gave rise to the formation of the Atlantic Ocean. Since the opening of the Proto-Caribbean is not well constrained by geological records, configurations with and without an open connection between the Proto-Caribbean

The Anatomical Record, EarlyView.Abstract A subadult Moschognathus whaitsi from the Eastern Cape Province, South Africa, was scanned using synchrotron radiation X‐ray computed tomography (SRXCT). Its subadult state allowed the cranial bones and teeth to be identified and individually reconstructed in 3D.

HYBODONT SHARKS OF THE ENGLISH BATHONIAN AND CALLOVIAN (MIDDLE JURASSIC) [PDF]
Palaeontology, 2008 Abstract: Recent bulk sampling and study of museum collections has revealed a high diversity of hybodont sharks from the English Bathonian, with 15 species being recognised. In addition, study of dental and skeletal material from the English Callovian has allowed the diagnosis of a new genus and species,Planohybodus peterboroughensisgen. et sp.
