Paluxy River ‘man prints’ may resemble human footprints superficially, but they lack the anatomy of real human footprints. Furthermore, dinosaurs and humans are of very different size and weight, but in the Paluxy River, tracks made by some undisputed dinosaurs and supposed humans are sunk to the same depth in the rock, which suggests that both types were made by creatures of the same general weight; there are tracks, made by different dinosaur species sunk to different depths. In the same way, the distances between footfalls of those tracks made to the same depth are spaced the same distance apart, showing that they were made by creatures with similar stride lengths.

Also when looking at authentic bipedal footprints which do exist, we need to accurately differentiate between bipedal animal, hominids, and finally modern humans.
This is NOT a human:
