What is an adaptation that may have helped dinosaurs survive?

Answer 1

• Dinosaurs probably had a high metabolism, allowing them to have an active lifestyle.
• They had an erect posture, giving them very efficient locomotion.
• Dinosaurs had air sac structures that allowed for a very efficient breathing system; like birds, they could absorb oxygen while inhaling and while exhaling. This system allowed them to also stay cooler.
• Dinosaurs had a wide variety of body plans for various lifestyles. Ankylosaurs had heavy armor and sometimes even tail clubs, making them nearly impossible to attack. Some dinosaurs were built for speed. Sauropods were too big for most predators and could reach food that other herbivores couldn't.
• Theropod dinosaurs had hollow cavities in the skull to make the head lighter, and many of them had a "honeycomb" structure to the bone, which also made them lighter.
• Some theropod dinosaurs had feathers, which could have been used for insulation or to attract mates.

Answer 2

An example is Leallynosaura, which had excellent night vision for seeing during the dark Antarctic winter. Timimus was a dinosaur species that hibernated through the Antarctic winter to survive. In the desert of Mongolia, some ankylosaurs had glands for excreting salt, which helped to preserve precious water.

Answer 3

Mammals were small. Many of them ate insects, which would have been plentiful despite the catastrophic extinction event. They also could reproduce very quickly to rebuild their populations after the dust settled.

Answer 4

Dinosaurs are animals, and need what most animals need to live. This includes food, water, and shelter. Each dinosaur is different, however, but this is the list of what most need.

Answer 5

Thare are many. How about "ambulation"?
