Palaeontologists discover over 200 fossilized eggs of flying reptiles in China
There are some discoveries that take us a step forward and then there are some that take us a leap forward.

Now this is one of them: A group of researchers have discovered hundreds of fossilized pterosaur eggs in northwestern China and this might provide us a completely new perspective in our understanding of flying reptiles. One of the reasons behind this is that pterosaurs are known to be the first creatures (excluding insects) that gained the ability to fly.  

And it is not just one or two eggs, these researchers have found more than two hundred such eggs at the Xinjiang Uygur Autonomous Region site. As per the research that has been published in the highly acclaimed journal Science, the eggs being of a species whose adults had a crest atop an elongated skull and had wings with a wingspan of more than 11 feet while as the creature itself would be about 4 feet tall. It is noteworthy that the creatures are assumed to have lived 120 million years ago. But about 65 million years ago, at the time when dinosaurs went extinct, pterosaurs went extinct as well.  

While fossils of Pterosaurs have been discovered earlier as well, what makes this discovery even more special is that this is the first time that the eggs of pterosaurs have been found with their embryos well preserved. 

But how did the fossils remain preserved for so long? According to the researchers these creatures lived near a large freshwater lake and the fossils of the creatures (along with the eggs), were washed into the lake where they were preserved and later turned into fossils. 

The researchers have also claimed that on the basis if the discovery, they can claim that when the pterosaurs were born, they did have the ability to walk but lacked the ability to fly and to gain that ability, they needed parental care.
