I don't know if you consider crocodiles to be "classic" reptiles, but some
captive saltwater crocs have reached 1000 kg., and Deinosuchus (or whatever
its proper name is) was a lot bigger than that.  I realize that you are
talking about land animals, but are there any weight estimates for the
largest mosasaurs?  Creatures like Shunisaurus and Kronosaurus must have
topped one ton, too.  I also wonder about something like Moschops, though I
realize that synapsids may have had a non-"reptilian" metabolism, whatever
that means.
