have some similarity to species that lived after it.

Explanation:

A transitional fossil is an intermediate form between an ancestral group and its descendants. It should show characteristics that are shared with both the earlier (ancestral) species and the later (descendant) species. This helps in understanding the evolutionary progression. For example, Archaeopteryx is a transitional fossil between dinosaurs and birds. It has features like feathers (similar to birds) and teeth and a long bony tail (similar to dinosaurs).

Answer:

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