From a newly discovered Early Cretaceous fossil site at the Sanlianhe Coal Mine in Tahe County, Heilongjiang Province, the most northern
area in China, two freshwater fossil fish had been recovered. This paper reports their classifications and implications regarding the
palaeobiogeography of the Jehol Biota. The fish assemblage consists of Yanosteus sp. (Acipenseriforms) and Sinamia sp. (Amiiformes). Both
are important members of the well known Jehol Biota, and their occurrence supports the correlation of the Yiliekede Formation at Sanlianhe
Coal Mine site with the Jiufotang Formation ofWest Liaoning. The remains of the Yanosteus sp. from this locality is the first known record of
the genus other than in the Yan-Liao area of China, and the specimens of Sinamia sp. is quite similar to what may be a new species of Sinamia
fromWest Liaoning. The new fossil site represents the most northern site that is undoubtedly part of the extent of the Jehol Biota as currently
understood. The northern Great Xing’an Range area is an important region that may link correlations between the Early Cretaceous
continental biotas of China, Mongolia and Russia.
