The Plesiosaur is the 7th Dinosaur obtained in the Mesozoic Valley Bubble Universe, which can generate Fossil.

In-Game Description[]

"Plesiosaurs were large aquatic animals with a broad, flat body, a long neck and tail, and four strong flippers. They were one of the first fossilized reptiles identified by humans, and were discovered in the early 1800s."



  • Aquatic Diapsid (Speed):

"The aquatic diapsids are the starting point for an extremely diverse group of animals including crocodils, lizards, snakes, turtles. They have two openings in the skull above and below the eye that enable the jaw to open more widely."

  • Flippers (Payout):

"Like their archosaur ancestors, Plesiosaurs retained their four-limbed structure. However, these legs evolved into broad, flat flippers that were used to propel their bodies through the water."


  • Aquatic (Speed):

"While no dinosaurs were truly aquatic, there were reptiles that lived in the oceans. These marine archosaurs, such as Plesiosaurs, Ichthyosaurs, and Mosasaurs, may have been air-breathing and warm-blooded."

  • Carnivore (Payout):

"Animals that feed entirely on meat, or the flesh of other animals, are called carnivores. About half of dinosaurs were carnivores. With teeth specially designed for ripping and tearing, some carnivours were hunters, while others were scavengers."

  • Triassic Age (Discount):

"The Triassic (251.9 MYA—201.3 MYA) was the first period of the Mesozoic Era. While the first half of this period was devastated by the Permian-Triassic Extinction Event, the second half is marked by increased diversity and the first appearances of dinosaurs."


  • Hollow Bones (Speed):

"The development of hollow or semi-hollow bones gave some dinosaurs a lighter but stronger skeleton system. This development would later enable them to evolve the ability to fly."

  • Herd Behavior (Payout):

"Some dinosaurs concregated in social groups, living in loose family units for defense against predators."

  • Feathers (Discount):

"It is still unknown to what extent therapodian dinosaurs were feathered, but evidence exists that shows that at least some of them presented with varying degrees of feathery skin coverings."

  • Warm Climate (Payout):

"During the Mesozoic Era, the Earth's temperature was very warm, which led to a great amount of geological and biological transitions. This climate set the stage for the major changes of the era."


  • King of the Sea (75 Plesiosaur):

"Plesiosaurs may have been warm-blooded. There is evidence that they breathed air and bore live young, similar to modern dolphins and whales."

  • Fishy Business (200 Plesiosaur):

"Plesiosaurs were some of the first prehistoric reptile remains to be discovered and identified. Their vertebrae were described as early as 1605, with the first partial skeleton being discovered in England in 1719."

Wikipedia's Info[]

Plesiosaurus (Greek: πλησίος ('plesios'), near to + σαῦρος (sauros), lizard) is a genus of extinct, 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. It is distinguishable by its small head, long and slender neck, broad turtle-like body, a short tail, and two pairs of large, elongated paddles. It lends its name to the order Plesiosauria, of which it is an early, but fairly typical member. It contains only one species, the type, Plesiosaurus dolichodeirus. Other species once assigned to this genus, including P. brachypterygius, P. guilielmiiperatoris, and P. tournemirensis have been reassigned to new genera, such as Hydrorion, Seeleyosaurus and Occitanosaurus.
