    Could you provide us a reference which convincingly reveals that
pterosaurs are LIZARDS?!!!

    "Leaping lizards!", David, it sounds as though you're talking about a
big leap of faith into fantasy!

    Any I suggest you lay off the "Hello, Dr. Beebe!" invective.  It may
come back to haunt you.  :)

    I'd prefer to discuss pterosaurs with someone with a TRACK RECORD than
with a faith axe to grind.

    Without a stitch of trackway evidence to back up such a statement,
shouldn't use of the word "apparently" (as applied to bipedal
locomotion) be
taken with a very substantial 'grain of salt'?
