When buying fossils from China buyers need to consider he authenticity of the goods. Authentic rare fossils that are complete are expensive, if they are too cheap to be true, they are unlikely to be authentic. Often the photos are so poor you won't be fooled, turtles with articulated heads, crocodile heads, other fossils with obviously hand drafted flippers/feet etc. Ignore the description they'll tell you anything to get a sale, hoping that the cheap price will make you ignore the feedback. However if you decide to buy watch out for inflated shipping costs and payment scams. My advice unless you really know your fossils and are absolutely sure you are buying the real thing don't bother.
