A stenlignende the subject, which was found in Antarctica back in 2011, has been a mystery for scientists the world over until now.
It is now established that it is 28 cm long egg, that looked like a punctured football is actually an egg, which originated from a prehistoric lake monster.
the Egg is very unlike other eggs which have been found from the same time. Its must is soft, tells geofysiskere from the University of Texas, who has studied the egg.
But what would come out of this 66 million year old eggs, if it was hatched?
It would have been a gigantic 'sea lizard', or as the exact name is: the mosasaur. In this ovum the event, it is thought that the mosasaur, which has put it, has been up to 18 metres long.
The ancient egg was found among the fossils of mosasaure and the remains of the other artefacts of the sea creatures as a plesiosaurus. It was found by a scientist from Chile in 2011.
In a small decade, the egg remained unknown to Chile's National Museum of Natural History.
One of the men behind the found, David Rubilar-Rogers from the chilienske museum, has since 2011 tried for the answer on where the egg originated from the work of many of the world's researchers, but it should only be in 2018 that he found Julia Clarke, a professor at the Jackson School's Department of Geological Sciences.
- I showed her the egg, and after a few minutes, she told me that it could be a 'dotted' eggs, says David Rubilar-Rogers.
the Eggs with the soft, are very hard to find, since they will not be preserved naturally as well as eggs with hard shell.
