Sauroposeidon
The press release in 1999 immediately garnered international media attention, which led to many (inaccurate) news reports of "the largest dinosaur ever!". While "Sauroposeidon" likely represents the tallest known dinosaur taxon, it does not hold records for either the longest or most massive. "Patagotitan" or "Argentinosaurus" make better candidates for the title "World's Largest Dinosaur" (presuming to ignore, as is conventional, "Amphicoelias"), though incomplete fossil evidence makes exact rankings impossible.

This hall contains the dinosaur called Antonio ("Tethyshadros insularis"), a hadrosauroid dinosaur dated 75 millions years ago, discovered in Villaggio del Pescatore paleontological site. It is one of the most complete dinosaurs that have been collected. 4-meters long and 1.3-meters tall, "Tethyshadros" lived on an island in the Western part of Tethys Ocean, between Africa and Northern Europe.
