Ok, here's Ray's answer that he's OK'd me to post here after I've articulated the question and had some back and forth about it:
“No. Except for maybe a single 'visual' hunch involved in only one out of the more than a thousand finds. People who say I must make my finds using psychic ability simply are '99.999999%' wrong. They underestimate what a well-informed (as to what to look for) visually sharp observer can notice. Why explain my discoveries as due to anything as not-understood as 'remote viewing', when except for that one possible instance, a much less mysterious reality is able to explain things. Then too, the 'professional' paleontologists are -- except for a few summer months -- tied down to, e.g., teaching university courses (and making tests and grading the results), so when 'in the field' for a few weeks in the summer, they are at both a temporal and a mind-set disadvantage. In contrast, I'm retired and can spend all the time I like just relaxing while looking for vertebrate tracks in stream beds and at Goddard, where there are dinosaur age outcroppings. In my personal situation I'm relaxed and not rushed, making the side of my brain that is most helpful in recognizing patterns much more accessible. Anyone who knows anything much about perception will understand the advantage."
The one possible instance he's referring to is where he had a 'hunch' that he might find something, and then he did. But he may have seen the site previously, and not consciously realized what he was looking at. Since he's found > 1000 tracks, he doesn't generally feel ESP has anything to do with it.
