Acrocanthosauruswas a bipedal carnivorous dinosaur that lived in what is now North America during the Early Cretaceous period (115-110 million years ago). At nearly 40 feet long and 6 tons, it was the largest predator of its time. Like most bipedal theropods, the forelimbs were too small to have reached the ground, and so were not used for walking.

• Scientific Name:Acrocanthosaurus, meaning high spined lizard, referring to the unusually tall spines on the vertebrae of the back.
• Characteristics:The vertebrae of the back ofAcroacanthosaurushave very tall spines along the backbone that served as attachment points for large back muscles, much like a modern bison. These muscles helped to support the large head, and stabilized the large body and tail. You can see evidence of this in the humped back of the model.
• Size and Color:It is a medium brown in color with a dark stripe running along its back. Both sides of the face have been reconstructed in a very light color. Although we have no direct evidence for this, Many dinosaurs, like birds today, have brightly colored facial markings that allowed theAcrocanthosaurusto recognize anotherAcroacanthosaurs, and distinguish it from another, similar theropod dinosaur.

History

Partial skeletons ofAcrocanthosauruswas first discovered in Oklahoma in the early 1940s, and named in 1950. Because a lot of the bones were missing, we werent sure exactly whatAcroacanthosauruslooked like. In the 1990s, much more complete skeletons were discovered. These skeletons provided more information on the unusual spines on the backbone and allowed us to understand how the front limbs were used for hunting.
