Acrocanthosaurus lived in North America during early cretaceous period, about 125 to 100 million years ago. The fossils were found in Oklahoma and Texas. This dino was probably the largest carnivorous dino of its time. Acrocanthosaurus could grow up to approximately 12m (40 ft) in length and weigh about 7 tons. It is related to Giganotosaurus or Allosaurus. The feature of Acrocanthosaurus is the high spine which is similar to the one of Spinosaurus, but only lower. The function of this spine is still unknown. Paluxysaurus got its name in 2007. This dino is probably related to Brachiosaurus and plant-eater. The size is about 60 ft in length and 22 tons in weight. Paluxysaurus lived around 110 million years ago. The fossils were from the Twin Mountains Formation in Texas which also included the remains of Acrocanthosaurus. Deinonychus was also living about 119 to 105 million years ago. The fossils were found in Montana, Wyoming, Oklahoma and Texas. Deinonychus might have to wait Acrocanthosaurus to finish eating.
