Plesiosaur Dinosaur Grows Magically from a Capsule

Plesiosaur dinosaur video for kids.

See how the Plesiosaur dinosaur sponge grow out of a magic capsule within a few minutes. Amazing! Can even see the capsule softening and dropping away!

The Plesiosauria or plesiosaurs are an order or clade of Mesozoic marine reptiles, belonging to the Sauropterygia. Plesiosaurs first appeared in the latest Triassic Period, possibly in the Rhaetian stage, about 203 million years ago.

A typical plesiosaur had a long neck, a broad flat body and a relatively short tail.Their limbs had evolved into four long flippers, which were powered by strong muscles attached to wide bony plates formed by the shoulder girdle and the pelvis. The flippers made a flying movement through the water.

Plesiosaurs breathed air, and bore live young; there are indications that they were warm-blooded.

The smallest were about 2m long as adults, the largest were enormous pliosaurs up to 20m long, comparable in size or even bigger than sperm whales (Physeter). They were possibly the biggest predators of all time.

This simple water experiment not only helps in our parent-child bonding with Leeroy, it also humbles us that we do not know the names of these dinosaurs and gives us an opportunity to learn together. 🙂
