in the region was dominated by fluvialestuarine
systems. Basin subsidence
combined with the supply of huge volumes
of sediments led to the accumulation
of thick sand units on vast coastal
plains in the Early and Middle Jurassic.
During the Late Jurassic, transgressions
led to deposition of extensive marine
mud, although sandstones are locally
preserved. Paralic depositional environments
prevailed during the Late Jurassic
and into the Early Cretaceous in southern
Scandinavia. Scandinavia hosts a
rich Jurassic palaeontological record including
fossil plants, sharks, dinosaur
footprints, ammonites, belemnites, ichthyosaurs
and pliosaurs. Miospores provide
the primary tool for biostratigraphic
subdivision and correlation of the continental
Jurassic sediments, whereas ammonites,
dinoflagellates and foraminifera
are the main groups employed for
marine biostratigraphy. However, much
work remains to be completed to
achieve a highly resolved zonation
scheme that integrates both marine and
terrestrial indices.

Strata of Jurassic age occur extensively
across onshore Australia, but they
are predominantly of non-marine origin.
Marine Jurassic strata have only limited
onshore exposure in northwestern and
central-western Australia, with thick marine
sequences lying offshore on the
North West Shelf. The richest petroleum
province in Australia is located at the
shelf's southern end, where the Dingo
Claystone represents an important
source rock for oil and gas. By and large,
non-marine deposits, including economic
coals, are distributed in the eastern
states. Jurassic stage boundaries, in
the main, are poorly constrained with
respect to the Australian sedimentary
succession. New work on microfossils,
plants, fish, and zircon dating is providing
a basis for improved correlation
across Australian basins, with overseas
successions, and recent international
IUGS geologic timescales.

The patterns of spatial differentiation
of the Early Mesozoic terrestrial biota in
Eastern Europe and Australia-Tasmania
demonstrate that the tetrapod faunal recovery
following the Permian extinction
was characterized by both global and
regional heterogeneity. Local distinctions
observed in the development of
Early Triassic tetrapod assemblages of
European Russia allow the recognition
of the following realms: (1) the central
and northern regions of the East European
Platform (Moscow-Mezen Syncline)
and the Timan-North Ural Region;
(2) the southern Fore-Urals, including
the Obshchii Syrt Plateau; and (3) the
southern regions of the East European
Platform (the slope of the Voronezh Anticline).
Climatic conditions at the initial
stage of the development of local communities
were characterized by an increase
in aridity and seasonal contrasts
of climate. Therefore, terrestrial assemblages
mostly concentrated in the
aquatic and coastal biotopes. Accordingly,
vertebrate assemblages of the region
were dominated everywhere by
aquatic amphibians and semiaquatic reptiles,
while the accompanying palyno-
