A Giant Pliosaurid Skull from the Late Jurassic of England

Pliosaurids were a long-lived and cosmopolitan group of marine predators that spanned 110 million years and occupied the upper tiers of marine ecosystems from the Middle Jurassic until the early Late Cretaceous. A well-preserved giant pliosaurid skull from the Late Jurassic Kimmeridge Clay Formation of Dorset, United Kingdom, represents a new species, Pliosaurus kevani. This specimen is describ...

Nannotanyderus oliviae sp. nov. from the Lower Jurassic (Sinemurian) of England, the oldest representative of family Tanyderidae, is described and illustrated. 

WARM TO COLD WATER CARBONATE FORMATION DURING THE ORDOVICIAN AND THE JURASSIC: EXAMPLES FROM IRAN, AUSTRALIA, AND ENGLAND

Isotope data from bulk carbonates, micrite, marine calcite cements, non-skeletal grains and brachiopods indicate deposition of a wide spectrum of warm to cold water carbonates during the Ordovician and the Jurassic. This isotopic interpretation is supported by warm to cold climatic models proposed for the Ordovician and the Jurassic. These carbonates formed during the Greenhouse mode (condition...

A Diapsid Faunule from the Lower Jurassic Of

provide a test for the hypothesis of faunal change at the Triassic-Jurassic boundary recently proposed by OLSEN and SUES (1986). They are remarkable for the numerical abundance and quality of preservation of the bones, the lithological diversity of fossil-bearing deposits, and the excellent degree of stratigraphic resolution. The vertebrate remains from the McCoy Brook Formation currently repre...
