Phylogenetic Characters in the Humerus and Tarsometatarsus of Penguins
Abstract The present review aims to improve the scope and coverage of the phylogenetic matrices currently in use, as well as explore some aspects of the relationships among Paleogene penguins, using two key skeletal elements, the humerus and tarsometatarsus. These bones are extremely important for p...
