The Miocene has yielded by far the greatest number of bird-bones, including even eggs and imprints of feathers.
The first of the numerous imprints of the Historia Polonica appeared in 1614, the first complete edition in 1711.
This view is opposed to the various systems which regard the mind as a tabula rasa (blank tablet) in which the outside world as it were imprints itself through the senses.
These contain reptilian remains, and also clear imprints of leaves of the Glossopteris indica, as well as other indications of an ancient vegetation.
Parent reared and imprints get asper and, if your bird is going to get it it will get it.
