Environmental distribution of Bathonian (Middle Jurassic) neoselachians in southern England [PDF]

open access: yes, 2004
Within the Bathonian (Middle Jurassic) a wide range of depositional environments were present across Britain. Within this dominantly carbonate shelf setting, there is a general palaeoenvironmental transition from open marine shelf in the south of England,

PALYNOLOGY EVIDENCES OF HITHERTO UNRECOGNISED JURASSIC SEDIMENTATION IN RAJMAHAL BASIN, INDIA

open access: yesRivista Italiana di Paleontologia e Stratigrafia, 2004
In Rajmahal Basin the Upper Gondwana (Mesozoic) sequences are represented by the Dubrajpur and Rajmahal Formations. Palynologically, the Dubrajpur Formation is shown to be a time transgressive unit spanning from Early Triassic to Early Cretaceous. Out of

Middle – Late Jurassic (Late Bathonian – Tithonian) Palynomorphs

open access: yesJournal of Micropalaeontology, 1985
Abstract. INTRODUCTIONJurassic palynomorph assemblages have been recovered in numerous wells in northeast Libya. Jurassic rocks reflect changing sedimentary environments which have greatly influenced the composition of the palynological assemblages.In the northernmost area, Jurassic sediments unconformably overlie the Palaeozoic or Triassic and show a ...
