Megalneusaurus rex (fwd)
Gary Kerr kindly passed on the info that Bakker presented on
_Megalneusaurus rex_ at Dinofest. At last, this beast might get some
attention! For those of you that missed it, this is what Colin McHenry
had to say on the animal earlier this year (Jan 17th). If you've read it
before, apologies for cluttering. And Colin, if you're out there, I'm

Since he wrote this, Colin may have gotten the lit he was looking for
off Tracy. What? Tracy - an inexhaustible collection of literature?
Don't make me laugh;-)
