We have analyzed nearly 75 Late Triassic metoposaur individuals from various parts of the
world including India. A new method of comparing skull outlines of metoposaurs has been
worked out. A new species of Early Triassic trematosaur has been recognized with the help
of this method. One paper has been published on morphometry of the metoposaurs -

A growth series of from several individuals of the chigutisaurs of the Late Triassic Maleri
Formation of Pranhita Godavari Valley has been identified.

Over and above a complete picture of Triassic temnospondyls of India, has been attempted
from total 12 taxa identified from India including 3 new combinations and 1 new taxon.
