Paper, 'On the nature and limits of reptilian character in mammalian teeth' by Harry Govier Seeley

Description

Seeley writes: 'Approximations between reptiles and mammals have been recognised in many parts of the skeleton. They are most marked between certain genera and orders of the two classes. The oldest known fossil representatives of both groups certainly approximate closer towards each other in all known parts of skeletons than do the orders which survive; so it may be a legitimate induction that, in an earlier period of geological time, the characters of both groups were so blended, that there existed neither the modern reptile, which has specialised by losing mammalian attributes, nor the modern mammal, which has specialised by losing the skeletal characters which have come to be regarded as reptilian.'
