The development of the osteocranium of Pleurodeles waltlii Michahelles

Abstract Under optimal conditions the development of the osteocranium covers the major part of the larval period and lasts about three and a half months. The earliest ossifications are of dermal origin and concern the tooth‐bearing bones. The poorly developed enchondral ossifications found in Urodela, appear at a much later stage, just before metamorphosis.
