Closes: Sept. 7

“Jurassic Oceans: Monsters of the Deep” takes you back in time to experience a prehistoric underwater world as you’ve never seen before. When dinosaurs ruled the land, the oceans teemed with equally fascinating and fearsome creatures. Explore the astonishing life of ancient seas, from the mighty Jurassic plesiosaur to the colossal megalodon that lived millions of years later, and uncover the captivating story of their evolution and ecosystems. Striking fossil specimens, including fully articulated 3D models and life-size casts, show ferocious predators and unusual prey in their natural habitats and tell the story of how they adapted to survive. Plus, this bilingual English and Spanish exhibition is filled with exciting hands-on activities that invite the imagination to swim wild!

T-Rex of the Sea

The next section, “T. Rex of the Sea,” features over 30 different species of mosasaurs. These mosasaurs were the main predators during the Cretaceous, with some having sharp teeth adapted to catching and holding onto scaly fish, while others had especially hard teeth to crush the shells of ammonites.

Marine Reptiles Today 

“Marine Reptiles Today” showcases the modern descendants of ancient marine reptiles. Approximately 66 million years ago, an asteroid hit the Earth, leading to the extinction of 75% of all animals, including most marine reptiles. While less diverse today, species like the leatherback turtle, saltwater crocodile, marine iguana, monitor lizard and the sea snake continue to thrive in today’s oceans.
