Lambeosaurus was a lumbering plant-eater that was bigger than most of the predators trying to eat it about 70 million years ago-it was even bigger than T-rex. This dinosaur moved in herds to help protect itself from danger while it munched on plants using a mouth that was crammed with teeth. One signal from a member of the "tribe" sent dozens of the beasts running away on their hind legs. They Lived in The Late Cretaceous Period, They Are Found in North America, They Are Borned in 1923.
Adult Lambeosaurus would have grown to around 7–7.7 m (23–25 ft) long and weighed 2.6–3.4 t (2.6–3.3 long tons; 2.9–3.7 short tons). It was able to move on two or four legs, with a deep tail, long limbs, and a highly distinct, hollow cranial crest. This crest, which can be used to separate the three recognized species of Lambeosaurus, projects well above the eye and slightly over the snout, and adults of some species possess a backwards spur. The function of the crest, which is also found in other lambeosaurines, is debated historically, but modern studies show that it could have been used as a resonating device for vocalisation, with a secondary function of s***** or species identification. The crest also allows for the identification of juveniles, which are otherwise nearly indistinguishable from those of Corythosaurus. It is through this identification that the growth of Lambeosaurus is well-known, with the crest developing late but expanding in height by an order of magnitude by the time individuals reached adulthood. Skin impressions are known and show that it had unornamented scales across the entire body.
The species of Lambeosaurus are only known from the middle Campanian of the Dinosaur Park Formation of Alberta. L. clavinitialis is known from a restricted range as the oldest species, overlapping with L. lambei which lived for around 0.3 million years before L. magnicristatus evolved later in the Campanian. This temporal separation suggests that L. clavinitialis, which was previously believed to be a female of either L. lambei or L. magnicristatus, is a separate species or at least earlier population. Lambeosaurus would have lived alongside the lambeosaurines Corythosaurus and Parasaurolophus, and also the saurolophine Prosaurolophus. Dental wear suggests that Lambeosaurus would have avoided competition with Prosaurolophus by occupying different feeding niches, preferring more closed habitats and browsing lower to the ground with a more generalised diet. The habitat Lambeosaurus lived in was a coastal plain where meandering rivers separated regions of dense vegetation, covered in a diversity of conifers, ferns and other shrubs, and occupied by diverse invertebrates, fish, mammals and reptiles, especially other megaherbivorous dinosaurs.
