A further account of the triasic mammals

The very contentious ‘facts’, and their possible interpretations, concerning the Triassic mammals are re-examined and new data are brought forward. The most important matters concern the structures of the lower jaws; the details of the two jaw hinges; the facts concerning tooth replacement; the possibility of epipubic bones having been recognized; the nature of the roots of the postcanine teeth; the relations of the upper and lower molars during biting; and the taxonomic results of these considerations.
