294 The Origin of Birds and Flight

This fossil shark from the
Carboniferous period (354 to
292 million years ago) indicates
that the shark existed in its pre-
sent-day form millions of years
ago.

This fossilized ginkgo tree leaf from
the Triassic period (251 to 205 million
years ago) is identical to present-day
ginkgo leaves. This and many other
similar fossil specimens totally un-
dermine the claim that living things
evolved from one another.
