The presence of an ovarian follicular hierarchy is a characteristic feature of reptiles and birds.

## Abstract The discovery of several dinosaurs with __filamentous integumentary appendages__ of different morphologies has stimulated models for the evolutionary origin of feathers. In order to understand these models, knowledge of the development of the avian integument must be put into an evoluti
