TRIASSIC TETRAPOD COMPLEXES OF THE TIMAN-NORTH URAL REGION

Abstract

The Triassic of the Timan-Northern Ural region contains analogues of the neorachitome, parotosuchid, and heptasaur faunas, the last fauna presently being not known from other parts of the USSR. However, of the three groups of the neoarchitome fauna in the Lower Triassic of this region only one - the wetlugasaur group (second complex) - is reliably identified, while no elements of the tupilakosaurid group have thus far been found. Therefore, it is most important to search for terrestrial vertebrate remains in the base of the Triassic section of this region. It will also be important to prospect for tetrapod remains in Middle and Late Triassic deposits.
