GLY1102 Exam 2 Questions with Verified
Correct Answers
True or False: all members of the clade Thyreophora were quadrupedal (walked on 4 legs).
False
Scutellosaurus is a primitive ornithischian that is grouped in with the Thyreophoran clade
becuase:
it has small armored plates on along its back.
The most primitive known stegosaur is _____, which lived during the _____ period.
Huayangosaurus, middle Jurassic.
The one features all members of the clade thyreophora have in common is:
armor plates made of bone.
True or false: Stegosaurs had hooves on the ends of their toes.
True
The hind limbs of Stegosaurus were:
much taller and more pillar-like than the front limbs.
Which of the following characteristics do all members of the stegosaurid clade exhibit?
small and low (vertically short) heads with long snouts.
Members of the stegosaurid clade are assumed by many paleontologists to have had low
intelligence because:
they have the smallest brain cavity size to body size of any dinosaur.
While stegosaurs had brains that were overall very small, the front part of their brains were
enlarged compared to the rest, meaning the likely had:
a very good sense of smell.
According to the Module 8 material, which of the following is considered a well-accepted idea
as to the function of stegosaurus' scutes:
, thermal regulation/ display
The reason it is challenging to determine the exact placement of stegosaur's scutes on it's
body is:
they are anchored in the skin, and often detach from the body before the skeleton is preserved.
When reconstructing stegosaurus fossils, the scutes are arranged in two rows instead of one.
This arrangement is based on:
the use of the scutes as radiators/thermal regulators.
Which group within the ankylosauria clade had a club tail?
ankylosaurs
Ankylosaur means "fused lizard", a name they get from:
fused vertebrae in their backs.
Compared to stegosaurs, ankylosaur diversity was:
much more conservative, with little variation over time.
True or false: nodosaurids likely had a much better sense of smell than ankylosaurids.
False
Which of the following features is NOT found on Nodosaurs?
horns and armor on the posterior part of its skull.
Nodosaurs had a longer and more narrow skull than ankylosaurs.
True
The ankylosaur Gastonia is classified as a:
unclear, because it has features that match both ankylosauridae and nodosauridae
The ankylosaur Zuul crurivastator was named after:
a movie monster.
Stegosaurs and ankylosaurs are united in a group called _______.
Thyreophora
The scutes of stegosaurus were:
embedded in the skin and not directly attached to the skeletal structure.
