That the www is full of creationist crap, with relatively little to debunk it.
Although it's not specifically what you're looking for, here's a website that attempts to debunk some of the fake claims put out by creationists:

Claim:
"The Paluxi River basin contains footprints of dinosaurs, side-by-side with human footprints. This is proof that man and dinosaurs were contemporaneous, and that dinosaurs are not millions of years older."
This is absolutely false, and it's amazing that this argument keeps cropping up. The famous "man tracks" in the Paluxi river have been examined again, and again, and the results are the same every time. The alleged "man" tracks are 2-1/2 times the size of a large human foot, too large to be that of a human. They don't even have toe imprints, as would be expected, if a human made them. The prints are vaguely "bean-shaped", much like a human footprint, but when you see a cast of them, it is obvious that these prints are not human. Also, there is a 1-to-1 correlation with the Dinosaur tracks that these footprints are next to. In fact, it becomes more apparent when you see a sequence, that the "man" tracks, in effect, are part of the dinosaur's print -- they are the impression of one of the toes or footpads.
Some creationists argue that the print is that of a race of giants referred to in Genesis, but where are the fossils of these giants? There is no physical proof of these giants.
As for other kinds of peculiar finds, like those unearthed during mining and so forth, they're examined on a case-by-case basis. Nature sometimes reworks fossils and human artifacts into younger strata.
But unless "young" artifacts found in old strata are found
in situ and not as the result of screenwashing, they are highly questionable.
At a paleontological site where I worked for a number of years, what appeared to some stone tool experts to be a chert spearhead was found during screening of the dirt removed during excavation. The site was believed to predate the arrival of humans in this hemisphere, so the artifact caused some initial excitement. Because no other artifacts (if the find was indeed a human artifact and not made by nature) were ever discovered during excavations, nor any more found during screening, it is thought by the site's scientists that the artifact wasn't really a human artifact and/or it was planted as a hoax.
