The Spinosaurus is a strong dinosaur who strikes fear into the hearts of his opponents. The Polar Bears are a strong race, but in the end they just don’t have the power that The Spinosaurus has. The Spinosaurus wins this match with his incredible speed and power. Spinosaurus wins.

Oh come on! Even Ursus maritimus tyrannus only got to about 1 tonne. Spinosaurus is 15 metres long and 7.5 tonnes(2014 estimate.) And if you want to stick with the old estimate of 18 metres and 13 tonnes, the situation is worse for the ursid.
True, it’s definitely very one sided here!
