          Liaobatrachus grabaui was a frog of the Cretaceous. The systematic paleontology of it is:
       
      Amphibia Linnaeus 1758
      Lissamphibia Haeckel 1866
      Anura Rafinesque 1815
      Pelobatidae Bonaparte 1850
      Liaobatrachus Ji and Ji 1998
      Liaobatrachus grabaui Ji and Ji 1998
       
          The holotype (GMV 2126) was found in the Yixian Formation at Sihetun in Liaoning Province, China. It was unearthed in strata dating to a Cretaceous interval of 125 - 121 million years ago (Barremian-early Aptian). This geological strata had previously been considered to be late Jurassic. [Note - The source of the information on the revision of the age is an article by Carl C. Swisher, Wang Yuan-qing, Wang Xio-lin, Xu Xing, and Wang Yuan. The title is Cretaceous age for the feathered dinosaurs of China. It was published in 1999 in Nature 400: 58-61.]
          Shu'an Ji and Qiang Ji wrote an article titled The first Mesozoic frog from China (Amphibia: Anura), Liaobatrachus grabaui gen. et sp. nov. It was published in 1998 in Chinese Geology, pp. 39-49. The text is on this link. A skeletal drawing is included.
