<正>The pterosaur record is generally poor,with little information about their populations,and pterosaur eggs are even more rare,with only four isolated and flattened eggs found to date.Dr.WANG Xiaolin,Institute of Vertebrate Paleontology and Paleoanthropology(IVPP)of the Chinese Academy of Sciences(CAS),and his team revealed a new pterosaur-rich area with potentially thousands of bones,including tridimensionally preserved male and female skulls and eggs discovered together for the fi rst time in the Early Cretaceous deposit of the TurpanHami Basin,south of the Tian Shan Mountains in Xinjiang Uygur Autonomous Region,northwestern China.On June 6,the researchers reported online a population of a new sexually dimorphic pterosaur species(Hamipterus tianshanensis gen.et sp.nov.),with five exceptionally well-preserved three-dimensional eggs in Current Biology,providing new and important evidence regarding male and 相似文献
