There is the example of Marcus Ross who seems to be able to so compartmentalize that he can do valid paleo work (for example categorizing ammonites fossils to improve dating in the Cretaceous) where he freely acknowledges that the Cretaceous was well over 65 million years ago, but then when he is in the big money Christian Cult of Ignorance venues he claims to support a literal Biblical young earth.
Now of course he is employed by Liberty University and so part of that is forced on him by contract, but I personally have problems with what I see as his (and even more the Christian Cult of Ignorance' use of his credentials) as misleading and misrepresentation. In his speaking at YEC marketing shows his Ph.d from the University of Rhode Island is also referenced, subtly implying that a secular university indorses what he happens to be speaking on at the YEC conclave.
Of course, that is simply false. It is just another example of palming the pea, misdirecting the audience attention, lying.
Another example is John Baumgardner, who does do some valid work, but his work also totally refutes the YEC material he markets.
Anyone so limited that they can only spell a word one way is severely handicapped!
