A bit further along, on the edge of Secondary Island, is a group of marine reptiles. This one is a Plesiosaurus, a genus which lived in the early Jurassic.
Plesiosaurus was a genus of large marine sauropterygian reptile that lived during the early part of the Jurassic Period, and is known by nearly complete skeletons from the Lias of England.
This sculpture on Plymouth's Barbican is officially known as The Leviathan and was created in 1996. It became known as the Sea Monster but somehow the name Prawn stuck. It is however an amalgamation of many types of creatures found on the Barbican. The 'Prawn' has a cormorant’s feet, a plesiosaurus’s tail, the fin of a John Dory, a lobster’s claws and the head of an angler fish.
"Plesiosaurs had a broad flat body and a short tail. Their limbs had evolved into four long flippers, which were powered by strong muscles attached to wide bony plates formed by the shoulder girdle and the pelvis. The flippers made a flying movement through the water. Plesiosaurs breathed air, and bore live young; there are indications that they were warm-blooded.
Plesiosaurs were among the first fossil reptiles discovered. In the beginning of the nineteenth century, scientists realised how distinctive their build was and they were named as a separate order in 1835. The first plesiosaurian genus, the eponymous Plesiosaurus, was named in 1821. Since then, more than a hundred valid species have been described. In the early twenty-first century, the number of discoveries has increased, leading to an improved understanding of their anatomy, relationships and way of life." (from Wikipedia)

On the endless Gobi Desert, there suddenly appear countless criss-crossing earth mounds in different heights, like ancient castles. It is said that screaming and shouting sounds can be heard at night when wild wind passing through the earth mounds with sands and stones. In fact, the Demon City is inside the typical Yadan Landform (a wind erosion physiognomy formed in dry areas) Area, which was formed because of dry climate and strong wind.
As early as more than 100 million years ago (in cretaceous period), there was no Demon City but a huge fresh water lake where there lived thick plants and ancient animals such as Wuerhe Stegosaurus, Plesiosaurus, Dinosaur and Junggar Pterosaur-a paradise for the water creatures. At that time, extensive lake facies stratums were formed. Then the lake gradually rose to be become the land and the dinosaurs, fossils. Finally, typical Yadan Landform was formed in Demon City.
