@TheCobbler,
footprints made IN shales and siltstones usually represent environments of lacustrine mud flats or delta sediments that have been piled layer upon layer , each well defined layer 'laggerstatte" often contains trace fosils of footprints and casts and molds of gastropods etc.
In the PALUXY Formation of TEXAS (Albian age of the Cretaceous) are many tracks and mud wallows (Ichnofossils) of herds of vegetarian animals of that age (In the Paluxy Shale and Siltstones it was an environment of Delta muds marshes and rivulets that debauched from highlands to the North and were cyclically inundated by tides.
The dino herds<Mostly Creaceous Hadrosaurs and Struthiomines and Galiaforme (Chickne -like dinoaurs weighing a few tons. In among these fossilized tracks were "Tracks" of human-like folks. These were claimed by Creationists to be fact, thus opening another dispute of age/date fossils that were not accepted by cience.
Like the Pitdown man, hose very credibility depended on glues and shellacs.Thats why Piltdown Man, knoown from the erly twentieth century and incorporating many credible scientists as support, wasnt shown to be a fraud (Ultimately) until C14 techniques were validated and chemsitr advanced enough to measure to the ppm level. Anomalous
Xray, C14, and shellac and rabbit glues were found in the fossil and C14 wrapped it up as a fraud (BUT NOT TILL THE 1959s).
The PAUXY shale "human footprints" were really found to be fa kes MIcro optics enabled chemitry to be analyzed by polar microscopy.
Then, two hillwilliams came forward and claimed that they were PAID by a Fundamentalist church that was pushing Creationim, to gouge out some of the hadrosaur prints and then carve toes and foot arches.
The IDers are just like that, they claim valid science then its found out they lied about some basic point of science that took a decade or more to be varified by emergent technology.
SO FAR, there is nothing that was yet found to be even remotely supportive of their worldview.AMAZING eh?
