Correctly match the development of the ankylosaurus tail characteristic with the period of time:
A) flexible tail- Cretaceous
B) flexible tail- Jurassic
C) Stiff tail-Jurassic
D) Tail club-Jurassic

The two species that were analyzed in the study by Wtimer:
A .Panoplosaurus and Euoplocephalus
b. Pinopolosaurus and Euopolocephalus
c.Pinacosaurus and Ankylosaurus
d.Stegosaurus and Scutellosaurus

The nickname of the four spikes on the tail of Stegosaurus nicknamed (as a result of a Far Side comic)
a) Terminator
b) Thagomizer
c) Thosogizer
d) none of the above

This is not a characteristic of Stegosaurus:
a) Greater difference between hind limb and forelimb
b) Larger osteoderms
c) They are closely related to Huayangosaurus
d) Group of dinosaurs with double row bony plates

2) True or false:
The ankylosaurus tail was flexible both laterally and vertically.

The CT Scans revealed:
A. low SA/V ratio due to large nasal passageways
B. high SA/V ratio due to small brain
C. low SA/V ratio due to small nasal passageways
D.High SA/V due to large brain

The type of dinosaur that was killed by the tail of a Stegosaurus in the example shown in the presentation
a) T-rex
b) Apatosaurus
c) Allosaurus
d) Velociraptor

The Stegosaurus locomotion was this fast:
a) They were not travelling at high speeds due to long hindlimbs
b) They were fast runners
c) They could walk at a moderate speed
d) They could barely move due to their giant body

3) The ankylosaurus develop the tail club at this point:
A) birth
B) after learning to walk
C) early adolescence
D) after sexual maturity

This did NOT contribute to the evolution of nasal passageways:
A. High environmental temperature
B. Large body size
C. Net gain of heat in surrounding the blood vessels
D. Evaporation of the moisture from the nasal pasageways

Outside of the direct attack example, this is another form of proof that Stegosaurus used its tail to attack other dinosaurs:
a) There is no other evidence
b) The broken plates on its back
c) The broken tips of spikes on its tail
d) B and C

Which dinosaur is the most similar to Stegosaurus?
a) Scelidosaurus
b) Tyrannosaurus
c) Ankylosaurs
d) Giganotosaurus

4) This is NOT directly required to estimate impact force;
A) density of bone
B) mass of bone
C) acceleration of tail
D) height of vertebral column

This is how the nasal passageway thermoregulated:
A. The cooling effect- Evaporation of moisture in the passageways
B. Looping passages draw heat from blood vessels to warm air going to lungs, while blood vessels nearby cooled blood going to brain
c. Increasing SA
d. All the above

Name one of three types of impacts inflicted by the tail of the Kentrosaurus:

Which one is not a possible function of Stegosaurus plate?
a) Visual deterrent to attackers
b) Thermoregulation
c) 'Blushing'
d) Defense
