Countries
Fourteen species of Titanosaurus fossils have been discovered in different continents. It has been found in Europe, in particular England and Romania. There have also been discoveries in Argentina, Madagascar, India and Laos. All of the remains were found near what was once a natural water source.
Areas of Water
It is believed some species of titanosaurus were not able to support their heavy body weight outside of water. This type of titanosaurus would have needed to suspend its body in swampy waters to maintain its balance. Other watery habitats for the dinosaur included marine shorelines and estuaries in tropical areas and small islands. They also inhabited floodplains.
Uplands
Some fossils show certain species of titanosaurus had straight hind legs. Dinosaurs with straight hind legs could have lived in upland areas and stood to reach plants in tall trees. Large ferns would have been a common source of food for an animal like titanosaurus. However, upland territory would have been dangerous for a titanosaurus, which was likely tremendously slow. Large predators like the Tyrannosaurus Rex would have preyed on the dinosaur.
Food Supply
Any habitat the titanosaurus was in would have needed a vast supply of plants for it to survive. The dinosaur must have stuck to coastal marine waters where it easy access to land plants as well as sponges, fungi spores and diatoms. It could also feed on gymnosperms, which grew in upland areas.
