Paralititan

After earlier digs at a location about 300 kilometers (186 miles) southwest of Cairo, Egypt, found a gigantic 1.69-meter- (5.5-foot-) long femur (thighbone) and a collection of broken shoulder blades, front limb bones, teeth, and vertebrae, Paralititan stromeri was named in 2001. The finding of such a huge femur led many paleontologists to claim that Paralititan was as enormous as Argentinosaurus. The titanosaur's length and weight are estimated to be between 25 and 30.5 meters (82 and 100 ft), with a weight of 60 to 75 metric tons (about 66 to 83 tons). Some 94 million years ago, Paralititan plied the Cretaceous Period's mangrove wetlands.

Scott Hartman predicts a giant creature that is still smaller than the largest titanosaurs like Puertasaurus, Alamosaurus, and Argentinosaurus. Gregory S. Paul estimated its length to be 20 meters (66 feet) and its weight to be 20 tonnes in 2010. Holtz provided a length of 32 meters (105 feet) and an estimated weight of 65.3-72.5 tonnes in 2012. It was estimated to weigh 50 tons in 2016 using methods that estimate body mass based on the circumference of the humerus and femur of quadrupedal mammals (55 short tons). Gregory S. Paul predicted Paralititan to be between 30-55 tonnes in 2019.
