The Acrocanthosaurus has incredibly short forelimbs - so short, it can’t even scratch its own neck!

Acrocanthosaurus means 'high spined lizard.' This apex predator looks like a Tyrannosaurus with a hunchback!

The best preserved Acrocanthosaurus skeleton ever discovered was found in Oklahoma - its name is Fran!

At 38 feet and weighing over 6 tons, the Acrocanthosaurus was one of the biggest land-dwelling predators ever!
