Bipedal lizards

["Dictator-for-life Calvin" <MWEDEL@gslan.offsys.ou.edu>]

Thanks to all who responded about the bipedal lizard

BUT

I've known about the basilisk and the Australian frilled lizard being 
able to do the emergency biped thing for a while, but I could have 
sworn that not too long ago I saw a post about a Central American 
lizard that is really, truly, honest-to-goodness habitually bipedal.  
If I remember right, the lizard in question had either just been 
discovered, or just been discovered to be a biped.

I really hope I'm not losing my mind, so if anyone out there knows 
what I'm talking about, please drop me a message.

Thanks in advance,
Matt Wedel

P.S.  If anyone has a reference on this, it would be greatly 
appreciated.  BTW, my box turtle laid its eggs last night--seven of 
'em!  Whoo-wooo, baby turtles!
