Los condrictios constituyen un clado sumamente conservado y vulnerable a la explotación, que ha cobrado una importancia creciente en los últimos años. Sin embargo, existe poca información sobre los aspectos morfológicos ...
Morphological variation in a conservative structure: The Scapulocoracoids in Sympterygia acuta Garman, 1837 and Sympterygia bonapartii Müller & Henle, 1841 (Chondrichthyes: Rajidae)
(Magnolia Press, 2017-09)
Scapulocoracoid variation in Sympterygia acuta and S. bonapartii was analyzed inter- and intraspecifically, and the utility of this structure as a diagnostic character in skates was evaluated. Skeletal pieces were obtained ...
