Discovery of a disaur fossil has caught attention of scientists all over world. This disaur fossil belongs to Spisaurus. Spisaurus aegyptiacus was equipped with a paddle-shaped tail and that helped predator to swim through water like a crocodile. This also threw light on question of can disaurs swim?

According to a report in National Geographic,  Spisaurus weighed seven-ton and was about fifty feet long. From fossil of disaur, it can be seen that it had a large tail on back and a sut that made it look like a crocodile. After disaurs’ tail was assembled, it required five tables to keep tail.

Can disaurs swim?

discovery of disaurs’ tails has led to rise of question of can disaurs swim? According to journal Nature, this is one of best aquatic adaptations that anyone has ever come across. fossil was discovered in Morocco and this threw light on way that animals lived in those times. This has also given rise to contrary tions that disaurs did t live only on land.

According to a vertebrate palaeontologist Nizar Ibrahim, he referred to disaur as a river monster. According to Ibrahim, this breed of disaur lived near water bodies and dined on seafood for survival. presence of cone-shaped teeth as discovered in fossil of disaur would have been very helpful for disaur to catch slippery fishes. For a paper in Science in 2014, Nazir and his or colleagues reported that Spisaurus had dense bones when compared to or ropods. This could be seen as an evolutionary adaptation to aquatic life by this species of disaurs.

tail of disaur showed bony projections on vertebrae, long neural spines, and this led to development of a fin-shaped tail. ropods had usually stiff and inflexible tails but Spisaurus had a flexible tail. power of tail was tested via robotic controllers and plastic versions of tail shapes. It was found that tail of this disaur was better than tails of disaurs and at par, with semi-aquatic animals we kw about. Though tail might be present only for display purposes, re remains a chance that disaurs were t completely land animals and that y too swam in waters.
