There has been man footprints and dinosaur footprints found side by side, in Glen Rose, TX.

Which arguments should definitely not be used?
Paluxy tracks prove that humans and dinosaurs co-existed. Some prominent creationist promoters of these tracks have long since withdrawn their support. Some of the allegedly human tracks may be artefacts of erosion of dinosaur tracks obscuring the claw marks. There is a need for properly documented research on the tracks before we would use them to argue the coexistence of humans and dinosaurs?
