‘Jurassic Park III’ got the Spinosaurus wrong. It was a nightmarish aquatic monster.

Ever since the first discovery of the terrifying Spinosaurus aegyptiacus by German paleontologist Ernst Freiherr Stromer von Reichenbach all the way back in 1912, scientists through the centuries have debated whether the dinosaur was land or water dwelling.

Most hypotheses would point towards land, while there was a strong minority that begged to differ.

But that debate has finally been put to rest.

Thanks to a new discovery published in Cretaceous Research, scientists can now confirm that the Spinosaurus was indeed an aquatic dinosaur.

In case you’re not familiar with the Spinosaurus, it’s that gigantic T-Rex-killing dinosaur with a vast sail on its back in Jurassic Park III:

Excavations at the Kem Kem riverbed in the Moroccan Sahara Desert uncovered more than 1,200 fossilized teeth, belonging to the Spinosaurus.

“The huge number of teeth we collected in the prehistoric river bed reveals that Spinosaurus aegyptiacus was there in huge numbers, accounting for 45 percent of the total dental remains,” says corresponding author of the study David Martill.

No teeth from other land-dwelling animals were found, which adds even more substance and confirmation to the theory that the Spinosaurus was a river-dwelling dinosaur.

“The enhanced abundance of Spinosaurus aegyptiacus teeth, relative to other dinosaurs, is a reflection of their aquatic lifestyle.”

Researchers also believe that the Spinosaurus had web-like feet to help propel itself underwater.

It even had a long snout, similar to that of a crocodile.

Basically, it’s a terrifying, gigantic croco-duck then.

The Spinosaurus was basically on top of the food chain during its time on this planet. It was big enough to take down other carnivorous dinosaurs, and could survive both on land and in the water.

It’s the dinosaur Ace of Spades.

If you’re curious about how dinosaurs even came into existence, one theory links them to a apocalyptic volcanic eruption.
