Ac. Milner, THE AISTOPOD AMPHIBIAN FROM THE VISEAN OF EAST KIRKTON, WEST-LOTHIAN,SCOTLAND, Transactions of the Royal Society of Edinburgh. Earth sciences, 84, 1994, pp. 363-368
One of the rarest tetrapods in the East Kirkton fauna is an aistopod r
epresented by very fragmentary material of five individuals. It is des
cribed as a new species of the genus Ophiderpeton which is redefined a
nd restricted to broad-snouted forms with large, robust teeth from the
late Visean and early Westphalian. Later Westphalian species are refe
rred to the genus Oestocephalus.
