Explanations: answer key for all 10 questions
- Q1: Roughly how long is a large Tyrannosaurus skull?
Answer: About 1.5 meters
Sue's skull is about 1.5 meters long.
- Q2: What do scientists estimate about Tyrannosaurus bite force?
Answer: It was among the strongest of any land animal
Estimates range from about 35,000 to over 50,000 newtons.
- Q3: How long could a Tyrannosaurus tooth be, including the root?
Answer: About 30 centimeters
Thick teeth are sometimes called killer bananas.
- Q4: Why were the teeth serrated?
Answer: To grip and tear flesh
Serrations worked like a steak knife.
- Q5: What did forward-facing eyes give Tyrannosaurus?
Answer: Binocular vision for judging distance
Studies suggest its depth perception was better than a hawk's.
- Q6: What does the large olfactory bulb suggest?
Answer: An excellent sense of smell
Brain casts show big smell centers.
- Q7: Why did the skull have large openings?
Answer: To save weight and anchor muscles
Fenestrae lightened the skull and gave room for jaw muscles.
- Q8: Why is Sue's real skull displayed separately at the Field Museum?
Answer: It is too heavy to mount on the skeleton
The mounted skeleton carries a cast.
- Q9: What evidence shows Tyrannosaurus crunched bone?
Answer: Bite marks and bone in its fossil dung
Coprolites contain bone fragments.
- Q10: What happened to Tyrannosaurus teeth over its life?
Answer: They were replaced continually
New teeth grew to replace broken ones.
Tyrannosaurus Skull Quiz – The Head of a Giant Predator
Tyrannosaurus rex had a skull about 1.5 meters long, built for a powerful bite. Scientists estimate its bite force at roughly 35,000 to over 50,000 newtons, among the strongest of any land animal.
Its thick, serrated teeth, up to about 30 cm long including roots, gripped and tore flesh and could crush bone, as shown by bite marks and bone fragments in fossil dung. Teeth were replaced throughout life. Large openings in the skull saved weight and anchored muscles.
Forward-facing eyes gave it binocular vision, and large olfactory bulbs suggest a keen sense of smell. The famous Sue specimen's real skull is displayed separately at Chicago's Field Museum because it is too heavy to mount.
