While exploring the coasts of east Darwin (some
made up name), you find the skeleton
of an apparently large organism on the beach.
The skeleton is approximately 25m long, and appears to be some type of
vertebrate-like organism. The organism
has four relatively short limbs, attached to a heavy pectoral and pelvic
girdle. There is no soft tissue left on
the skeleton to assist you on your investigation. Because of it’s location, you are at first
unsure if it is an aquatic organism that washed up on the beach, or a
terrestrial organism that died near the seashore. What skeletal
structures would you look for to determine if it was aquatic or
terrestrial? Explain why the structures
you have mentioned are important in determining aquatic or terrestrial origins
for the organism?
