Explanation:

A transitional fossil is a fossil that shows characteristics of both ancestral and descendant species. It bridges the gap between different groups of organisms in the evolutionary timeline. So, it should share some similarity with species that lived before it (ancestral forms) and some similarity with species that lived after it (descendant forms).

Answer:

share some similarity with species that lived before it and some similarity with species that lived after it.
