Autor: Lisa Schnetz, Cathrin Pfaff, Eugen Libowitzky, Zerina Johanson, Rica Stepanek, Jürgen Kriwet

Publikováno v: BMC Evolutionary Biology, Vol 19, Iss 1, Pp 1-13 (2019)

Abstract Background Chondrichthyans represent a monophyletic group of crown group gnathostomes and are central to our understanding of vertebrate evolution. Like all vertebrates, cartilaginous fishes evolved concretions of material within their inner

Contributions to the skeletal anatomy of freshwater stingrays (Chondrichthyes, Myliobatiformes): 1. Morphology of malePotamotrygon motorofrom South America

Autor: Jürgen Kriwet, Rica Stepanek

Publikováno v: Zoosystematics and Evolution. 88:145-158

The skeletal anatomy of most if not all freshwater stingrays still is insufficiently known due to the lack of detailed morphological studies. Here we describe the morphology of an adult male specimen of Potamotrygon motoro to form the basis for furth
