Searching for the ‘magic bullet’
Why do creation-defenders often seem to be too quick to jump onto the latest ‘evidences’?
by Ken Ham
In 1986 a number of leading creationist researchers decided that the evidence of supposedly human and dinosaur footprints, found together at the Paluxy River in Texas, had serious problems. They decided that, pending further research to establish the correct interpretation of the prints, they could no longer be safely used as evidence supporting the fact (based on the biblical account of creation) that man and dinosaur lived at the same time.

So I guess we just don't know for sure yet. Hopefully they will find more evidence.
