EDMONTOSAURUS
EDMONTOSAURUS was one of the biggest of the
"duck-billed" dinosaurs. Living in vast heards, these
giants probably migrated across the North American
continent with the change of seasons, much as animals
like the wildebeast does today. Unlike many other
hadrosaurs, Edmontosaurus did not have a head
crest. It's believed they may have had an inflatable
nasal sack with which to make noise (the bony crest
on other hadrosaurs are thought to have had that function
also). The tip of the mouths of hadrosaurs ended in
a beak used to crop vegetation for food. Inside the
mouth were rows of teeth used to grind the vegetable
matter into a pulp for ingestion. These dinosaurs
disappeared in the final great extinction that ended
the reign of the dinosaurs.
