Beipiao Sturgeon Fish Fossil

I saw an interesting fish fossil for sale at the Arizona Historical Society Museum at Papago Park gift shop in October 2014.

The label said, "The Beipiao sturgeon was discovered in the area of west Liaoning Province of China. It was formed in land facies layer of the Late Jurassic Period. It was about 130,000,000 years ago."

If I recall correctly, the length was over 20 cm and the price was $250.
