The Tanystropheus is a Protorosaur that appears in the lost world section of the lost and found. It first appears in the episode of the same name.


It is a long, tall, orange reptile with red stripes on its back and neck. It has short, smaller legs and red around its eyes.


"Lost and Found"

While Ginger and the other lost kids chase SpongeBob through the lost and found, they pass through the lost world. SpongeBob rides on a Tylosaurus, while Ginger and the other lost kids ride in a box on a Tanystropheus' back.

At the end of the episode, when Squidward is lost in the lost world, a Tanystropheus can be seen walking around.

Lost Treasures

A Tanystropheus reappears as an obstacle in level 5. Like "Lost and Found," it carries the lost kids on its back.
