36 How are Saurischian dinosaurs distinguished from Ornithischian dinosaurs?
50 What major steps did the following proto-mammals achieve that led them on the path to becoming mammals? Pelycosaurs Therapsids Cynodonts
51 Pelycosaurs – Sail used for the beginning of thermoregulation Therapsids – Legs moved under the body Cynodonts – Lumbar ribs reduced
52 How did the present distribution of marsupials, monotremes, and placental mammals come to be?
53 -Monotremes and marsupials evolved on Pangaea and spread out. -Australia, Antarctica, & India broke away -Placental mammals developed on Laurasia and conquered the rest of the landscape except for A,A, and I -India re-collided with Asia flooding it with placental mammals and Antarctica froze -Australia the only place left isolated and warm enough to support mammalian life
