Re: Size limits



Argentinosaurus isn't even the largest found to date. There is as yet, an unamed sauropod found in Argentina about 2 years ago that estimates put at over 160ft. in length. As far as individuals in the over 25% size larger are concerned, it is highly unlikely. Argentinosaurus is already in blue whale territiory when it comes to its estimated weight, finding a specimen much over 100 tons would be a miracle of biological engineering.

The chances that the known specimen of Argentinosaurus is the largest individual that ever lived is vanishingly small: there are almost certainly larger individuals out there in the fossil record.  My suspicion is that we are nearing the plateau of land animal size in Argentinosaurus, but that there might well be taxa which are 25-50% larger still to be found.                 Thomas R.

I would like to know if you think that Argentinosaurus  reached the upper size limit for a terrestrial animal or if you think that we can espect even bigger finds in the future?  Jan Grönvik, Sweden
