and palaeogeographical framework of the earliest diversification of tetrapods (Late Devonian).
correlations of Early Devonian vertebrate assemblages of the Old Red Sandstone Continent.
This study has been accomplished using physical stratigraphy, sedimentological features of the sections, and the limited biostratigraphical
Determination of the number of zones in a biostratigraphical
However the unit lacks integration of the biostratigraphical
and sedimentological data for sequence stratigraphic analysis.
In this paper the results obtained from the biostratigraphical
analysis of 13 samples from the Cansona Formation are presented.
After preparing samples and making thin sections, lithostratigraphical and biostratigraphical
studies were precisely performed.

setting of the area see Behrensmeyer (1987, 1988), Willis (1993), Behrensmeyer et al.

This is based on biostratigraphical
research done jointly by BP and the Geology Institute of Azerbaijan.
