Where did u get the size of Spinosaurus

In a 2005 study in the Journal of Vertebrate Paleontology, researchers estimated Spinosaurus was 52 to 59 feet (16 to 18 m) long and weighed 7.7 to 9.9 tons (7 to 9 metric tons), based on extrapolations from skull measurements. However, other scientists took issue with the study's methods, and instead claimed the behemoth was 41 to 47 feet (12.6 to 14.3 m) long and 13.2 to 23 tons (12 to 20.9 metric tons), according to a 2007 study in the same journal.

The partial Spinosaurus skeleton Ibrahim his colleagues analyzed suggests the specimen was 50 feet (15.2 meters) long and still growing. The fossils also suggest Spinosaurus' long neck and trunk shifted the dinosaur's center of mass forward. This allowed the animal to move easily in water, but made movement on land nearly impossible unless the dinosaur used all four legs
