What kind of dinosaur is the biggest ever found?

Love the info given on the questions...always something to learn.

I'm from Greece originally but a bit younger than these fossils...although I may qualify as a living fossil according to Guinness World Records

198,000’LBS!

Jon Humphris, what was its main diet i wonder..?

It was the only plural answer choice.

Taramaiden, are you referring to the skull of Richard III, recently excavated under a parking lot in England, to show his resemblance to extant paintings of that king who died at the battle of Bosworth?

In 1993, another titanosaur called Argentinosaurus huinculensis claimed the title of largest land-based dino, but was later superceded by the even larger titanosaur Patagotitan mayorum in 2014. However, it's challenging to determine which species was the heaviest dinosaur — Argentinosaurus is known from just 13 fossilized bones, and Patagotitan's weight was based on a composite of six individuals

millwallmarty, you can calculate body mass and density by the size and structure of the skeleton. It's possible to building accurate and lifelike portraits by building layers of modelling clay onto skulls (Richard II is a prime example) so calculations of an entire skeleton are perfectly possible.
