Question

which of the following would be considered an example of original remains fossil?
an impression of leaves in mud.
cast of a trilobite
a fly in amber.

Explanation:

To determine the original remains fossil, we analyze each option:

• "An impression of leaves in mud" is a mold (impression), not original remains.
• "Cast of a Trilobite" is a cast (formed from a mold), not original remains.
• "A fly in amber" preserves the actual organism (the fly) in amber, which is an example of original remains fossil as the organism's body is preserved in its original form (or close to it) in the amber.

Answer:

C. A fly in amber.
