Longfengshania
Longfengshania is an extinct genus of enigmatic eukaryote, ranging from the Statherian into the Ediacaran.
Among the previously identified pre-Cryogenian macroalgae, Longfengshania is unique due to it possessing a stipe, blade, and holdfast-like structure.
Description
Longfengshania is most commonly found as an oval to discoidal blade sitting on top of a usually thin stipe. Specimens from the Shiwangzhuang and Jiuliqiao formations have probable holdfasts at the base of this stipe.There is a wide range of sizes between species of Longfengshania, with the largest specimens coming from the Longshan Formation, bearing blades up to long and stipes up to long. The smallest specimens come from the Doushantuo Formation, with blades up to or under in diameter.
