Guaibasaurus Strike Attack
Guaibasaurus is an early dinosaur from Brazil that scientists still cannot place with confidence, sitting somewhere near the split between the meat-eating and the long-necked dinosaurs. Mattel added it to the first Strike Attack wave of Jurassic World Epic Evolution as a green figure with black legs, a black spiky head and a white stripe along the neck. Here is what the figure looks like, why it puzzles scientists, and how to unlock it in the Jurassic World Play App.

Family Puzzle: Where Does It Fit?
Guaibasaurus has been moved around the dinosaur family tree more than once.
Studies have placed it as an early theropod, an early sauropodomorph, or close to the base of both, and the debate continues.
What Is Strike Attack?
Strike Attack is the action assortment of Mattel’s Epic Evolution line. Each figure has one built-in strike move: press the button on its back and it lunges into an attack, no batteries needed. They also have movable joints and a DNA code that unlocks the animal in the Jurassic World Play App.
Guaibasaurus came in the first Strike Attack wave of Epic Evolution, alongside Kaprosuchus, Tuojiangosaurus and Velociraptor.
Paint and Colours
