Ontogeny of the Appendicular Skeleton inMelanosuchus niger(Crocodylia: Alligatoridae)

Zoological Science, 2016
The objective of the present study was to analyze chondrogenesis and the ossification pattern of the limbs of Melanosuchus niger in order to contribute with possible discussions on homology and the fusion pattern of autopodial elements and phylogeny. In the Reserva Extrativista do Lago Cuniã, Rondônia, Brazil, six nests were marked and two eggs removed
