Don't matter what fossil or evidence you present to creationists. They will never accept any of it.
i am a creationist and i believe in evolution. i accept those transitional fossils except for human.
i believe evolution is God's way of creating diverse life on earth.
i said this because if i were God, i would do the same. i believe this is the best way to populate earth with living creatures instead of creating them one by one which for me, is very tiresome and not practical. what i do instead is just make a blueprint of life that is programmed to evolve and to speciate. it doesn't matter if it would take millions of years since time is of no essence to God.
if we will read the verses in creation account, on the 5th and 6th day, we will notice that God just
LET the waters and earth bring forth creatures after their kind. "after their kind" looks "speciation" to me in our science subject.
