The+Hadrosaurs

=Hadrosaurs=

===These were the duck-billed dinosaurs.Hadrosaur is Greek for Bulky Lizard. There were two types of hadrosaurs, Lambeosaurinae and Hadrosaurinae. Lambeosaurinae have a crest, but Hadrosaurinae lacked a crest. Research says that these dinosaurs had webbed feet. They lived during the late jurassic period and the early creataceous period. They had horny, toothless beaks and hundreds of cheek teeth in the sides of their jaws. The duck-billed dinosaurs had the most teeth; they had up to about 900 cheek teeth. They ranged from 10 feet long to 40 feet long. They also weighed up to 3 1/2 tons.=== =prosaurolophus=
