Introduction
Adynomosaurus is a genus of hadrosaurid dinosaurs that lived in Spain during the late Cretaceous. Adynomosaurus means “weak shoulder lizard” in Greek as a reference to the evident unexpanded morphology of the shoulder blade or scapula. The species name arcanus means secret referring to the fact that skeletal elements of hadrosaurids informative of their taxonomy are rare in the South Central Pyrenean Basin. The only species, Adynomosaurus arcanus, was described by Albert Márquez and colleagues during 2019 in a paleontological journal called Cretaceous Research. The genus is represented by a left scapula (from which it got its name), cervical vertebrae, a sacrum, a complete tail, a sternal fragment, fragmentary remains of the pelvis, and partial forelimbs and hindlimbs. These were all discovered in the Tremp Formation in Spain. Adynomosaurus has been placed in the subfamily Lambeosaurinae of the family Hadrosauridae, which means it probably had a crest in reality since all the crested hadrosaurs go in that subfamily. Adynomosaurus lived with a lot of other animal genera including mammals, crocodilians, lizards, turtles, ankylosaurs, other hadrosaurs like Pararhabdodon, iguanodonts, rhabdodontids, sauropods, theropods, snakes, other squamates, various invertebrates, amphibians, and fish.
