Adynomosaurus arcanus
[Secret Weak Shoulder Lizard]
Etymology
Adynomosaurus is derived from the Greek "adýnamos" (weak), "—mos" (shoulder) and "sauros" (lizard), referring to its smaller shoulder blades, with reduced muscle attachment area, compared to other hadrosaurs. The species epithet,
arcanus, means "secret", "hidden", or "mysterious" in Latin, referring to the scant hadrosaur fossil record in the area and the uninformative nature of the few that have been found there.
Discovery
The first remains of
Adynomosaurus were discovered in the Conques Formation (Tremp Group) at the Costa de les Solanes locality, alongside a wheat field in Basturs village, near Isona i Conca Dellà, Lleida province, northern Catalonia, Spain, by a resident of Basturs in 2012. The holotype (MCD 7125) is a shoulder blade. Referred material, excavated from the same site by teams from the Institut Català de Paleontologia Miquel Crusafont and the Universitat Autònoma de Barcelona during 2012 and 2013, includes fossils that are pretty much indistinguishable from any other meat-and-potatoes hadrosaur.
