Question

Explanation:

Extinction means a species no longer exists. The disappearance of a type of fossil in the fossil record indicates that the species represented by that fossil has gone extinct. The appearance of a new species shows speciation, appearance of similar - bodied fossils is related to evolution and common ancestry, and presence of identical fossils doesn't imply extinction.

disappearance of a type of fossil in the fossil record
