<

>Scientists in China have discovered a fossil thought to be more than 120 million-years-old containing an embryo of a flying reptile that lived alongside the dinosaurs. 
<

>It is the only known fossil of an embryo of a pterosaur, a winged lizard that evolved powered flight. 
<

>Wang Xiaolin and Zhou Zhonghe of the <a href="http://www.cas.ac.cn/" target="_blank" >Chinese Academy of Sciences</A> in <a href="http://english.peopledaily.com.cn/data/province/beijing.html" target="_blank" >Beijing</A> said that dinosaur embryos have been discovered all over the world, but so far no pterosaur embryos have been reported. 
<

>The embryo is preserved in an almost complete egg and was found in the sediment of a lake in <a href="http://english.peopledaily.com.cn/data/province/liaoning.html" target="_blank" >Liaoning</A> in northeastern China that is known for its fossil riches. 
<

>The Chinese scientists said the Liaoning embryo has a wingspan of 10.6 inches, indicating that the embryo would have grown up into a medium-to-large pterosaur. 
<

>The earliest pterosaurs, the first known flying vertebrates, lived about 230 million years ago. They died out about 65 million years ago.
