Xianguangia is a soft-bodied sea anemone-like fossil animal from the Chengjiang Biota of China.

[2] Xianguangia sinica has a cylindrical body with a whorl of nearly 16 tentacles around the oral disc, similar to the modern anthozoans.

The tentacles are feather-like with dense pinnules on both sides of the axis which would have been well adapted to filter feeding.

A bowl-shaped attachment disc at the basal part might commonly have been buried in the sediment to allow its sedentary strategy on the sea floor.

[4] Studies from the late 2010s onwards argued that it was likely to be member of the stem-group of Ctenophora (comb jellies), related to taxa like Dinomischus and Siphusauctum.
