Adynomosaurus ("Weak shoulder lizard", in reference to the unexpanded shoulder blade) is a genus of lambeosaurine hadrosaurid dinosaur from the Late Cretaceous of what is now Catalonia, Spain. The type and only species is A. arcanus ("secret" or "occult", alluding "to the elusive findings of taxonomically informative skeletal elements of this and other hadrosaurids in the South-Central Pyrenean Basin"). It is based on MCD 7125 (Museu de la Conca Dellà, Isona, Lleida, Spain), a right scapula. This bone was one of a group of 34 bones recovered from the discovery site; the other bones have also been assigned to Adynomosaurus arcanus, and include vertebrae from the neck, sacrum, and tail, a sternal element, part of the pelvis, and parts of the forelimbs and hindlimbs. The discovery site, the Costa de les Solanes locality, is in rocks of the upper lower Maastrichtian Conques Formation.[1]
Discovery and naming[]
In 2019, the type and only species Adynomosaurus arcanus, was named and described by Albert Prieto-Marquez, Víctor Fondevilla, Albert G. Selles, Jonathan R. Wagner and Angel Galobart in paleontological journal Cretaceous Research. The generic name is a composite of the Greek words ‘adýnamos’ (weak), ‘-mos’ (shoulder) and ‘sauros’ (lizard), and is a reference to the characteristically unexpanded morphology of the scapular blade of Adynomosaurus. The specific name arcanus means "secret" or "occult", alluding "to the elusive findings of taxonomically informative skeletal elements of this and other hadrosaurids in the South-Central Pyrenean Basin".

Classification[]
Adynomosaurus is member of the Hadrosauridae that includes the clade Lambeosaurinae. It forms polytomic relationships with Aralosaurus, Canardia, Jaxartosaurus, Tsintaosaurus, Pararhabdodon and other most basal known lambeosaurines.
