Lecture 6 - functional morphology and behaviour Flashcards
1
Q
biomechanics =
A
reconstructing dinosaur capabilities
2
Q
small bipedal theropod and ornithopod speed:
A
20km/hr
3
Q
large bipedal theropod and ornithopod speed:
A
40km/hr
4
Q
quadrupedal stegosaur and ankylosaur speed:
A
6-8km/hr
5
Q
quadrupedal sauropod speed:
A
12-17km/hr
6
Q
quadrupedal ceratopsians galloping:
A
25km/hr
7
Q
what is Encephalization quotient (EQ)?
A
the ratio of the brain to the body mass
8
Q
when does a dinosaur have a high EQ?
A
when avoiding predators or hunting
9
Q
why do theropods have a range of EQs?
A
because some evolved into birds and birds have high Eqs as they have to process 3 dimensional information
10
Q
what can we look at for evidence of diet?
A
- teeth form
- jaw formation
- co-occurence
- coprolites
- gut content
- fortuitous finds
11
Q
oviraptors
A
eat eggs
12
Q
things to look at when determining thermoregulation?
A
- stance and activity levels
- adaptations for processing high volumes of food
- Haemodynamics - heart mechanisms
- Brain size
- Nose morphology
- Bone histology and growth rate
- predator-prey ratios
- core and peripheral temps
