The Upper Jurassic Morrison Formation has yielded one of the richest dinosaur faunas of the world. Morrison sediments are distributed over more than a million square kilometers in the western United States and represent a mosaic of riverine, lacustrine and floodplain environments developed on a vast alluvial plain nourished by debris from the ancestral Rocky Mountains. Plant productivity must have been reasonably high to support abundant large-bodied herbivores, but the absence of coals… 

The palaeoecology of the dinosaurs of the Wessex Formation (Wealden Group, Early Cretaceous), Isle of Wight, Southern England

It is concluded that climatic changes which took place in the Late Jurassic or Early Cretaceous resulted in the appearance of flow productivity vegetation and that this was incapable of supporting large sauropod populations.

The Late Jurassic Cleveland-Lloyd Dinosaur Quarry as a Drought-Induced Assemblage

Abstract A comprehensive taphonomic analysis has yielded a novel interpretation for one of the most famous dinosaur quarries in the world. The Cleveland-Lloyd Dinosaur Quarry (CLDQ) traditionally has

Taphonomic patterns of a dinosaur accumulation in a lacustrine delta system in the Jurassic Morrison Formation, San Rafael Swell, Utah, USA

The Upper Jurassic Brushy Basin Member of the Morrison Formation is widely accepted as having accumulated in a semi-arid meandering stream/floodplain ecosystem. However, in central Utah, the lower

Lowland–upland migration of sauropod dinosaurs during the Late Jurassic epoch

Comparison of oxygen isotope ratios of tooth-enamel carbonate from the sauropod Camarasaurus with those of ancient soil, lake and wetland carbonates that formed in lowland settings demonstrates that certain populations of these animals did in fact undertake seasonal migrations of several hundred kilometres from lowland to upland environments.

Taphonomy and suggested structure of the dinosaurian assemblage of the Hell Creek Formation (Maastrichtian), eastern Montana and western North Dakota

This study quantifies the taphonomic context of fossil dinosaur elements in the Late Cretaceous Hell Creek Formation of Montana and North Dakota, USA. A previously published data base consisting of

Palaeoenvironment and taphonomy of dinosaur tracks in the Vectis Formation (Lower Cretaceous) of the Wessex Sub-basin, southern England

Reptilian ichnofossils are documented from three levels within the coastal lagoonal Vectis Formation (Wealden Group, Lower Cretaceous) of the Wessex Sub-basin, southern England (coastal exposures of



Paleoecology of Dinosaur Provincial Park (Cretaceous), Alberta, interpreted from the distribution of articulated vertebrate remains

The distribution of articulated remains of fossil vertebrates is not uniform within the Oldman Formation (Campanian, Cretaceous) of Dinosaur Provincial Park, Alberta. The mesofauna gradually declines

A Consideration of the Trophic Dynamics of a Late Cretaceous Large-Dinosaur Community (Oldman Formation)

Calculations suggest that the annual secondary production of endothermic herbivorous dinosaurs would have been insufficient to meet the food requirements of anendothermic carnivorous dinosaur population as large as is preserved in the Oldman Formation.

New perspectives in vertebrate paleoecology from a recent bone assemblage

The Amboseli bone assemblage provides a modern analogue for taphonomical processes which may have affected fossil assemblages derived from paleo-land surfaces prior to fluvial transport and helps to define limits of resolution in interpreting paleoecological information from such fossil assemblelages.

Morrison, Cloverly, and Sykes Mountain Formations, Northern Bighorn Basin, Wyoming and Montana

The Morrison, Cloverly, and Sykes Mountain formations are the uppermost Jurassic and lowermost Cretaceous sedimentary rocks in the northern Bighorn Basin, Wyoming and Montana. Similar formations were

The Morrison of Oklahoma and Its Dinosaurs

The discovery of Morrison dinosaur bones in Cimarron County, Oklahoma, led to a study of the geology of the area. This investigation brought to light six deposits containing remains of these animals,

Sedimentation of dinosaur-bearing upper Cretaceous deposits of the Nemegt basin, Gobi desert

The Upper Cretaceous (? Campanian-Maastrichtian) deposits of the Nemegt Basin are clastic, continental sediments of red-beds type. Two formations were distinguished and named the Lower and Upper

A fossil flora is described from clay-filled fissures in the Carboniferous Limestone near Bridgend, South Wales, nearly all the specimens belong to the conifer Cheirolepis muensteri, which was previously known from compressed German specimens yielding cuticles but no other tissues.
