Jurassic Dinosaurs Flashcards
Q: What differentiated macronarian sauropods like Camarasaurus from diplodocids?
A: Macronarians had shorter snouts, spoon-shaped teeth, and robust bodies for eating tougher, woody vegetation.
Q: What were diplodocids, and how did they feed?
A: Long-necked sauropods with simple teeth for selectively nipping tender leaves, possibly rearing on hind legs for higher browsing.
Q: Which Jurassic dinosaur had a niche similar to modern deer or elk?
A: Stegosaurus, capable of selective feeding on low and medium-height plants.
Q: What group dominated Jurassic predation, and how were they unique?
A: Allosauroids, with stiffer spines and proportionately longer legs for greater speed and efficiency.
Q: What evolutionary significance did coelurosaurs have in the Jurassic?
A: Small, lightweight theropods that gave rise to birds and later dominated as diverse predators in the Cretaceous.
