They share a common ancestor.
What is one piece of evidence that could relate wooly mammoths to each other and show they share a common ancestor?
They share anatomical features such as trunks
Define three of the following ways in which fossils form:
Carbonization, Frozen, Tarpit, Amber, Trace
Carbonization-Flattened in earth and Pressurized
Frozen-Organism becomes trapped and freezes
Tarpit- Asphalt seeps up through earths surface
Amber-Hardened Tree Sap
Trace- Activity of the organism (footprint etc)
Which of the following WILL form a fossil: Carbonization, Land Decomposition, Freezing, Ocean Decomposition
Carbonization and Freezing

If three rock columns each contain Trilobites, how is it determined which rock Outcrop is Older?
The Outcrop where the trilobite is in the newer rock layers would be considered an older outcrop
What do index fossils do?
