What do you think about a crossover between The Land Before Time, Dinosaur (film) and Planet Dinosaur?

Spinosaurus: Length: 55 feet long. Quick facts: spinosaurus was the largest theropod on earth. It weighs about 6-10 tons. It had long arms and long claws. Spinosaurus walked in all fours but can stand on two legs if it was threatened or upset. But it mainly hunted fish and small dinosaurs. It may also had hunted dinosaur eggs. Tyrannosaurus rex: Length: 43-51 feet long. Quick facts: sue was only the most complete but not the largest. Umcp 137538 was confirmed to be the largest. Tyrannosaurus rex hunted triceratops, ankylosaurus, edmontosaurus, and even the mighty sauropod alamosaurus. It hunted in packs from 5-10 members. Tyrannosaurus rex had a bite force about 12,000 pounds or higher. It's skin had a lot of muscles making it thick. It may have been able to tough out wounds with some specimens surviving the injures but it is still unknown. But to me some may had been able to tough it out. It also had small arms that can lift up to 4,000 pounds. It also had bacteria in its mouth. So who will win? Tyrannosaurus rex will win due by having bone crushing jaws and hunting more dangerous prey. Spinosaurus will win 40% while Tyrannosaurus rex will win 60%. Spinosaurus claws cannot reach Tyrannosaurus rex. Due by potbelly and long neck. So it can only win if it takes place in water. Tyrannosaurus rex can just bite the sail or just bite the neck. Tyrannosaurus rex can swim but not that good. So spinosaurus can try to drown it. But Tyrannosaurus rex can still kill it but if they end up fighting on the surface. But if the spinosaurus kills it it will die. If Tyrannosaurus rex it can die from blood lost but that will be very low most times Tyrannosaurus rex will survive the injures. So this is why Tyrannosaurus rex rules for a reason.
