Actually, the most recent _Megalania_ work would be that of Ralph Molnar.


Dr. Molnar found 320kg to be about the average size of the _Megalania_ specimens currently known, with the largest individuals hitting 7 meters and 920kg.

Total length estimates in particular will depend largely on the length of the tail, which lacking any complete fossil specimens will usually be conjecture. Mass is probably a better way of comparing 'size', since a tail ending with a long thing whip-like structure won't increase the mass much, but could potentially add a metre or three to the total length.

Earlier one-tonne-plus mass estimates (Auffenberg gave the heaviest, at 2.2 tonnes) were almost certainly incorrect. I haven't read Molnar's book, but I'd be interested to know which specimens gave the 7m length estimate. Hecht gave a similar length estimate in 1975, which he extrapolated from a single phalanx!
