the largest predator on earth was able to hunt in the water. This was revealed in a Portsmouth University study. In the study it was revealed that Spinosaurus had solid bones that allowed them to dive to hunt for food.
“The bones in his body can’t lie,” said Nizar Ibrahim, a Palaeontologist at Portsmouth University.
In the study, a team from Portsmouth University and Chicago’s Field Museum performed cross-sectional comparisons of the femur and ribs of 250 extinct and living animal species.

Some of the animals for comparison were seals, whales, elephants, penguins, hippos, crocodiles, mice, hummingbirds, mosasaurs, and plesiosaurs. From this comparison, it is known that there are similarities between animals that hunt in water in the form of bone density and foraging behavior in water.
It turns out that the animals that dive and forage in the water have bones that are almost entirely solid. Unlike the animals that hunt for food on land, the bones in their bodies have a hole in the middle.
According to Nizar Ibrahim, solid bones are believed to help control buoyancy. That similarity is found in fossil Spinosaurus ever found in the Sahara desert in 2014.
