Default Spinosaurus discovered to be an aquatic dinosaur species

https://www.sciencefocus.com/news/ri...ived-in-water/

Spinosaurus aegyptiacus has recently been discovered to be an aquatic dinosaur after a newly-unearthed tail fossil was examined.

Quote:
The University of Portsmouth said: “Until now it was believed that dinosaurs lived exclusively on land, but the newly discovered tail of Spinosaurus aegyptiacus, a giant predator, shows that it was actually well adapted to an aquatic lifestyle.

“The 15-metre-long, six-tonne predator was, in fact, a powerful swimmer propelled by a huge fin-like tail, which hunted down its prey in vast river systems that flowed through the Sahara desert 100 million years ago.

“It is the first time that such an adaptation has been reported in a dinosaur.”
So, Jurassic Park III might have been heading in the right direction, then

Spinosaurus being (semi?)aquatic has been know for some five years now, but the discovery of this tail is another conformation of that, and also yet another new insight in what Spinosaurus really looked like. Its official appearance as known to science has changed a lot over the years...

I actually got some Spinosaurus teeth at home.

Probably not Spinosaurus, but others most definately did, no doubt about it. Sometimes we even know the colours of the feathers.

The tail of the beast looks positively newt-like.

I've learnt something new; some dinosaurs lived in water.

Dinosaurs certainly were a varied species; dinosaurs that lived on land, dinosaurs that lived in water, dinosaurs that could fly, etc. Not to mention how they varied in regards to size and shape; the T-Rex was enormous, raptors were closer to our size, and there were those puny green dinosaurs that looked like they were less than a foot tall.
