Chapter 2
Goals
1. Be able to identify
the key landmarks on the "typical" mammal skull.
2. Be able to identify
where to take common measurements on the "typical" mammal skull.
Do in lab
1. Identify structure #1-34 listed
in the "Key to Labeling of Figure 2.1" on p. 11
exceptions: #4, 5, 18, 19, 22, 26, 27, revision:
#24&25 = premaxilla; additions: cranium, mandible, braincase,
rostrum, nasal passages.
2. Identify the measurements on
pp. 10 - 11 marked with an asterisk (*).
Chapter 3
Goals
1. Preview material
on teeth for a later lecture.
2. Be able to identify
the dental formal for any mammal skull you may be presented.
Do in lab
1. Preview bold the terms
on pp. 13& 17 for a later lecture. (Don't memorize them now.)
2. Recognize the difference
between: incisors, canines, premolars, and molars.
3. Give the dental formulae
for the skulls provided.
a) What type of feeding strategy (herbivore, carnivore, omnivore) might
each have?
b) What might be the most likely common name for each mammal?
c) Are there similarities in dental formulae among the feeding strategies
or evolutionary histories?
Chapter 4
Goals
1. Be able to identify
the structures and layers in typical mammalian skin.
2. Be able to identify
the main types of hairs found on most mammals.
3. Be able to identify
the main types of mammalian color patterns and their function.
Do in lab
1. In your lab book,
do exercises: 4-A, 4-E, 4-F, 4-G .
2. Identify and give
functions of vibrissae, guard hairs, and underhairs. How might these
vary among the habitat and lifestyle of the mammal?
3. Give the function
(if any) of the following color patterns:
a. cryptic coloration, b. disruptive coloration,
c. countershading, d. aposomatic coloration(warning coloration),
e. Gloger's rule, f. albinism, g. melanism
