Track attack

Acrocanthosaurus is nearly as big as Tyrannosaurus rex and it would seem just as fearsome a predator. There are some dinosaur tracks in Texas called the Paluxy River tracks. Some palaeontologists believe that a set of these belong to Acrocanthosaurus and, if that's true, the tracks show it chasing Pelorosaurus (pe-LOH-ro-SORE-us), a type of sauropod twice the size of this predator.
