I. The lower Carboniferous microsaurs

Philosophical Transactions of the Royal Society of London. Series B, Biological Sciences, 1967
Abstract Redescriptions of Adelogyrinus simnorhynchus and Dolichopareias disjectus are given. The skulls of these forms are characterized by the very anteriorly placed small orbits and long post-orbital skull table. Further diagnostic characters are the exclusion of the ‘post-orbital’ from the orbit, the long straight suture between ...

A Lower Carboniferous Lepidodendropsis flora in Kashmir

Nature, 1979
The concept of a more or less uniform world-wide flora (the ‘Lepidodendropsis flora’) of early Carboniferous age, was first expounded by Jongmans1. He cited the fossil plant genera Lepidodendropsis, Triphyllopteris and Rhacopteris as characterising this palaeofloristic unit, of which he claimed representation from a number of Northern and Southern ...

The Palaeobiogeography of Eastern Australian lower carboniferous corals

Historical Biology, 2001
Eastern Australian Lower Carboniferous (EALC) corals are characterized by high endemism, with endemism indices of 50 in the Tournaisian and 44 in the Visean. The most closely related coral faunas occur in the Akiyoshi and Kitakami Terranes of Japan.

The Lower Carboniferous Marine Transgression

1974
By this time the old Caledonian mountains were much reduced by erosion and the essential feature of the Lower Carboniferous, which corresponds broadly to the rock-group called the ‘Carboniferous Limestone’, is the gradual advance, or transgression, of the sea over the lower areas.

THE LOWER CARBONIFEROUS IN A BORING AT ALPORT, DERBYSHIRE

Proceedings of the Yorkshire Geological Society, 1944
I. Introduction and Acknowledgements During the years 1937 to 1941 borings were drilled in Edale and Alport Dale in the Millstone Grit country of north Derbyshire a few miles north of the Carboniferous Limestone outcrop at Castleton. Both borings passed through the lower part of the Namurian and the upper part of the Dinantian and since they were both ...
