Canglong refers not to dinosaurs.

Canglong was a carnivorous marine reptile that lived in the Cretaceous period in Europe and North America.Canglong was not really a dinosaur.Canglong weighed 6 to 13 tons and was 9 to 17 meters long.

The Canglong looked somewhat like a mix of reptile and fish, with a 10-meter-long torso and a very slender body with four fins. It had a long tail at the back and its skin was covered in scales.

Life Habits of the Cangaroo Dragon:

Food is plentiful in the ocean, but competition is fierce. The most important food items for Canglongs were serpentodons, golden kitchen sharks, sea turtles, and lamellar dragons. The golden kitchen shark, a type of ancient shark that could reach 8 meters in length, was a medium-sized predator that combined speed and endurance.

Cangaroo's size gradually became larger and more ferocious as it evolved, and scientists speculate that an adult cangaroo could have fought off several golden kitchen sharks. The golden kitchen shark became extinct 82 million years ago.
