During the survey to develop the development plan of the Geopark, Professor Autur Sa of Trás-os-Montes e Alto Douro Portugal discovered Hue Bien fossil in the area of ​​Chin Don Phin village, Lung commune Pu, Meo Vac district.

The fossil site is located on the road from Meo Vac district to Khau Vai, 2km from Lung Pu commune headquarters.The Hue Sea fossil was discovered to be large in size, the density is thicker than other Hue Bien fossils in the park area. The Hue Bien fossil was found to enrich the geological heritage list on Dong Van Rock Plateau Geopark.

Sea lilies (Endoxocrinus parrae) bear this name because they resemble a flower that hangs on the ocean floor. However, according to US researchers, this is a echinoderm similar to sea urchins, capable of fleeing before the threat.

They are the oldest group of echinoderms that still exist today, with about 5000 fossils and more than 600 species living. Most sea lilies live with long stalks, a few live freely. Today people rarely see sea lilies, even though they once dominated the ocean floor.
