'Sichakou sedimentary member’ A weighted mean age of 130.7 Ma was reported using 40Ar/39Ar dating of the K-feldspars samples from the interbedded tuffs about 6m below the Protopteryx-bearing layer7, largely consistent with previous results using the SHRIMP U-Pb method31 |

Collection method comments: The two specimens (STM7-145, 7-163) of A. meemannae were acquired by the Tianyu Natural History Museum of Shandong from a fossil dealer. The dealer confirmed that the fossils were collected from the same locality of the holotype of Protopteryx fengningensis (IVPP V11665) in Sichakou basin of Fengning Country, Hebei Province, northeastern China. | |
