What is the heaviest dinosaur?

If you glance to the right (or above, if you're on our mobile site), you will notice a top ten list of the heaviest dinosaurs, plucked from our prehistoric database. The list will be automagically updated as heavier species are discovered.

Please bear in mind that extinct dinosaur sizes are based on often shabby remains using the not strictly scientific method of "guestimation". Soft tissue doesn't fossilize well, so the amount of heavy flesh and fat, tendons, skin, ligaments and cartillage, which all alter weight, are complete stabs in the dark. Note also, that different scientists have concocted their own method of estimating body mass, each of which yield dramatically different results.

This page displays the highest estimated weights (within reason) that have been suggested in the scientific literature using good ol' fashioned ink and paper. We will bet our bottoms that this list never displays anything that isn't a sauropod!
