- n. Any crested hadrosaurid dinosaur of the subfamily Lambeosaurinae
Sorry, no etymologies found.
Fossils of the lambeosaurine Amurosaurus riabinini form 90% of the recovered material.
Next to the hadrosaurs, identifiable by the fossilized mandibles found in the arechological sites of La Solana (Valencia) and Fontllonga (Lleida), were a lambeosaurine hadrosaurs yet to be defined, and a newly discovered lambeosaurine, the Arenysaurus ardevoli.
According to paleontologists, the new lambeosaurine lived between 65.5 and 68 million years ago, had a very prominent frontal dome, and its biogeographical relationships suggest a paleobiogeographical connection between Asia and Europe during the Late Cretaceous.
For example, many hadrosaurids previously reported to represent relatively small lambeosaurine species were demonstrated to be juveniles of the larger taxa.
These lambeosaurine taxa experienced cranial allometric growth and retained juvenile characters (neoteny) until the skulls reached approximately 50% adult size.
Dodson showed that extended neoteny and late stage allometry increased the morphological disparity between particular growth "stages" within the lambeosaurine taxa.
