Skeletal Anatomy, Phylogenetic Relationships, and Paleoecology of the Eocene Urolophid Stingray Arechia Crassicaudata (Blainville, 1818) from Monte Postale (Bolca Lagerstätte, Italy)
Journal of Vertebrate Paleontology
In this paper we re-examine the taxonomy and systematic position of the Eocene stingrays from Bolca Lagerstätte which are traditionally assigned to Urolophus crassicaudatus (Blainville). The analysis of their tooth morphology supports an assignment to the Eocene stingray genus Arechia Cappetta, a taxon known from isolated teeth from the Ypresian-Lutetian of northern and western Africa. The teeth of the Bolca specimens differ from the type species A. arambourgi in some characters (i.e., labialdoi:10.1080/02724634.2020.1803339 fatcat:ndabkeslvjapjj3cfgax7wgvoy
