If your Zoodinos fans devoured the latest issue about T. rex, they might like to learn about an even bigger predatory dinosaur: Spinosaurus!

Spinosaurus was enormous- up to 59 feet long and 21 tons. Its name means “spine lizard,” for the giant spikes along its back. Those spines are extensions of its back bones, and the longest ones were well over five feet long. It was discovered in Egypt in 1912, and it’s been fascinating both scientists and the general public ever since. One of its most remarkable traits is that it was probably divided its time between the water and dry land. Scientists think that Spinosaurus was largely aquatic because it has some features in common with water-dwelling creatures today, like its short hind legs (like a duck’s), a long snout for seeking  out prey in the water (like a crocodile’s). But in the water or on the land, you probably wouldn’t want to come across a Spinosaurus when it was hungry!
