TY - JOUR TI - Integrating developmental biology and the fossil record of reptiles AU - Skawiński, Tomasz AU - Tałanda, Mateusz T2 - The International Journal of Developmental Biology AB - Numerous new discoveries and new research techniques have influenced our understanding of reptile development from a palaeontological perspective. They suggest for example that transition from mineralized to leathery eggshells and from oviparity to viviparity appeared much more often in the evolution of reptiles than was previously thought. Most marine reptiles evolved from viviparous terrestrial ancestors and had probably genetic sex determination. Fossil forms often display developmental traits absent or rare among modern ones such as polydactyly, hyperphalangy, the presence of ribcage armour, reduction of head ornamentation during ontogeny, extreme modifications of vertebral count or a wide range of feather-like structures. Thus, they provide an empirical background for many morphogenetic considerations. PY - 2014 DO - 10.1387/ijdb.140322mt VL - 58 IS - 10-11-12 SP - 949 EP - 960 J2 - Int. J. Dev. Biol.
