An Oklahoma Dinosaur Adventure is an immersive exhibit created specifically for the Oklahoma Museum Network
funded by the Donald W. Reynolds Foundation. Measuring 1,500 square feet, Red Dirt Dinos features three animatronic
dinosaurs and numerous hands-on, interactive components. The exhibit explores dinosaurs that once roamed
Oklahoma and the science used by paleontologists to unearth the secrets of these great giants.

Red Dirt Dinos is included in Science Museum Oklahoma general admission.
Acrocanthosaurus – “High-Spined Lizard”
Pronounced: ak-ro-KAN-tho-SOR-us
Species: Acrocanthosaurus atokensis
Time Period: Early Cretaceous (115 to 108 million years ago)
Type: Bipedal/Carnivore
Height: 18 feet/5.5 meters – Length: 40 feet/12.2 meters – Weight: 13,600 pounds/6,169 kilograms

Acrocanthosaurus was the largest meat-eating dinosaur of the early Cretaceous in Oklahoma. It lived about 45 million years before the reign of Tyrannosaurus Rex. A formidable predator, Acrocanthosaurus had thick, muscular legs and powerful jaws capable of taking on even the biggest dinosaur in the region, Sauroposeidon. Its mouth was filled with large, sharp, curved serrated teeth designed for shredding and tearing meat from bones.
Deinonychus – “Terrible Claw”
Pronounced: Dye-NON-ik-us
Species: Deinonychus antirrhopus
Time Period: Early Cretaceous (115 to 108 million years ago)
Type: Bipedal/Carnivore
Height: 3.5 feet/1.1 meters – Length: 11 feet/3.4 meters – Weight: 175 pounds/79.4 kilograms

Deinonychus was a sleek, fast-moving and agile predator. It had keen eyesight, long arms with clawed grasping hands and a stiffened tail that gave it a well-developed sense of balance for running and jumping.
Tenontosaurus – “Sinew Lizard”
Pronounced: the-NON-toe-SOR-us
Species: Tenontosaurus tiletti, T. dossi
Time Period: Early Cretaceous (115 to 108 million years ago)
Type: Quadrupedal, Bipedal/Herbivore
Height: 13 feet/4 meters – Length: 23 feet/7 meters – Weight: 4,000 pounds/1,814 kilograms

Tenontosaurus used its powerful U-shaped beak to clip off pieces of plant matter. Rows of strong teeth with angled cutting surfaces in the back of its mouth ground up even tough plants. Tenontosaurus gets its name from the network of bony tendons that stiffen its extremely long tail. These tendons hold its tail out straight and help balance the front of its body. Tenontosaurus walked and ran on its two back legs, but it also had very strong front legs with short, wide feet that it used when it grazed on low vegetation.
