Dinosaur tracks in Texas can be found at Dinosaur Valley State Park. Two kinds of tracks are visible at the park ? those left by Sauroposeidon proteles and by Acrocanthosaurus.
Sauroposeidon proteles was similar in shape to the Brachiosaurus. It is estimated that Sauroposeidon was approximately 100 feet long and 60 feet tall, and it is considered to be the tallest dinosaur that ever walked the Earth. It lived during the Jurassic and Cretaceous periods. Acrocanthosaurus also lived during the Cretaceous period. At only 25 feet long, it was smaller than Sauroposeidon with a fin that ran along its body from neck to tail. Its tracks have a three-toed pattern.
