A lie, plain and simple. Almost every single fossil we find can be classified as a transitional of observed species. The fossil record is indeed very fractured, but is still a strong supporter of evolution.
Macroevolution is defined as a change in species, which has been observed.

"The geological record is extremely imperfect and this fact will to a large extent explain why we do not find interminable varieties, connecting together all the extinct and existing forms of life by the finest graduated steps. He who rejects these views on the nature of the geological record, will rightly reject my whole theory."
-Charles Darwin, as quoted by S J Gould, in "The Panda's Thumb," page 181.
In Darwin's time the fossil record was scarce, but with the millions of examples we now have, it is clear that there are no "interminable varieties" by which connections are made to transitional forms between species. The few that do seem to exist, are but the straws the drowning-in-truth materialists clutch at to keep Darwin's faulty premise from going the way of, well, the dinosaurs.
Microevolution is a physical fact, Macroevolution is faith-based. Evolutionism and Creation are both belief systems, but believers in Creation are honest about their foundation, while Evolutionists want their followers blinded by "science."
Darwin gives you permission to reject his views based on the geological record, which we now know is sadly lacking in evidence. Please consider doing so.
