STANCE: The next question
to consider is stance. Do carnivorous dinosaurs like Tyrannosaurus and
Dilophosaurus have a bipedal or quadripedal stance? The answer should be obvious
from the Museum trip.
Your next job then is to
survey modern vertebrates and make a list of those with a bipedal stance typical also of
tyrannosaurs and dilophosaurs. You should consider each class of tetrapod vertebrates.
Try to identify particular species or groups that have the same stance as our two dinosaurs.
At the minimum, you should
consider each animal in the list below. Ideally, you should evaluate as many amphibians,
reptiles, birds, and mammals as possible. Your goal is to identify animals that are good
dinosaur analogues with respect to stance. If you are not sure what some of these animals
look like, consult zoology reference material in the College Library.
ostriches, penguins, geese, sea gulls
humans, horses, goats, whales, bats, rats,
