Relying on fossils as evidence for the theory of evolution makes no sense, and never has.

The creation, and later discovery, of fossils are both random events. There can be no representative sample of a cross-section of fauna at the time, nor any idea of the population of a particular species extant at any particular time. A species might have numbered in the millions, but due to geographic location would leave no fossil trace.

For that reason, there can also be no certainty regarding any mutations that may have occurred within a species, even if similarities within specimens are found.

The only thing certain about a fossil, is that the fossilized specimen happened to be preserved, and later discovered.

Unusual, for a person to base their faith on such a random cascade of events.
