Titanosauria is a group of large, long-necked dinosaurs that lived during the Late Cretaceous period. They are known for their massive size, with some species reaching lengths of over 100 feet. Titanosaurs were herbivores, primarily feeding on plants, and their long necks allowed them to reach high vegetation. These dinosaurs were characterized by their unique skeletal features, including elongated limbs and a wide body. Fossils of Titanosauria have been found on every continent, indicating their widespread distribution. Notable members of this group include Argentinosaurus and Patagotitan, which are among the largest land animals to have ever existed.
