Lambeosaurinae (Lambeosaurine)
Translation: Lambe's Lizard
Lambeosaurinae (lam-be-uh-SAWR-ih-nay) is a subfamily of the hollow-crested,
duck-billed hadrosaurs. They were herbivorous and ranged in size from 15
- 40 feet (4.6 - 12.2 meters) long. They lived during the Late Cretaceous
Period. Remains have been found in North America and Asia. Corythosaurus,
Hypacrosaurus, Lambeosaurus, and Parasaurolophus.
Laurasia
Laurasia (lor-AY-shah) is the name of the northern part of the continent
that formed when Pangea broke apart 180 million years ago. North America,
Greenland, Iceland, Europe, and Asia made up Laurasia. The term "Laurasia"
is derived from the combination of "Asia" and the Laurentian
Mountains of Canada.
Life Span of Dinosaurs
It is not known how old individual dinosaurs lived to be; however, modern
reptiles, such as turtles and crocodiles, can live to be well over 100
years. It is not unreasonable to believe that the life spans of at least
the larger dinosaurs were similar. If dinosaurs were warm-blooded, the
comparison with reptiles is not as valid. But when you consider that elephants
and humans regularly reach 70 years or more, it isn't unreasonable to think
that the dinosaurs -- and especially the larger sauropods -- lived to be
at least as old.
