Lambeosaurinae /ˌlæmbiəˈsɔːraɪniː/ (meaning 'Lambe's lizards') is a group of crested hadrosauroid dinosaurs.
Description
Size Uncertainty surrounds the size of lambeosaurs from the European continent. Hadrosaurs found there, alongside other dinosaurs, have traditionally been considered representatives of the phenomenon of insular dwarfism, as the continent was then made up of many smaller islands. Many fossil remains from the continent are smaller than those of hadrosaurs found elsewhere in the world, with only isolated remains indicating individuals of adult size by the standards of their relatives in North America and Asia. It remains possible, however, that at least some cases instead represent misidentification of juvenile remains. The presence of genuine dwarfed taxa has been validated in some cases; adults of the genus Minqaria, for example, are thought to be around 3.5 metres (11 ft) in length. Contrastingly, the genus Pararhabdodon has a projected adult size similar to those of hadrosaurs on other continents, and known remains of Adynomosaurus and hadrosaurs from the Basturs Poble bonebed are of this adult size themselves. Why hadrosaurs of such variable sizes co-exist, despite being subject to the same environmental pressures, remains unclear.
