So this question asks us to choose a type of fossil and to explain how paleontologists might learn something about an organism based on this type of fossil.
00:12
And remember, there are different kinds of fossils.
00:14
There are traces or an animal leaves or a plant leaves a trace of something behind.
00:21
So think about something like footprints of a dinosaur that have become fossilized.
00:28
And in this case, you can imagine that footprints might be really important evidence of how an organism walked, for example.
00:39
How far apart were the feet? did it walk in sort of the feet in one line or out to the side? so you can imagine that a lot can be learned from the size and the pattern of footprints.
00:55
A mold or a cast, there's similar things, is where, an organism has left a kind of impression behind.
01:07
And think of like a lot of shells will leave, you know, a sort of imprint behind.
01:18
And in this case, you often get really detailed view of the surface of an organism.
01:33
So that's impression...
