Longfengshania is an extinct genus of enigmatic eukaryote, ^{[1] [2]} ranging from the Statherian into the Ediacaran. Among the previously identified pre-Cryogenian macroalgae, the Longfengshania is among the most unique due to it possessing a stipe, blade, and holdfast-like structure.

Description

Longfengshania is most commonly found as a 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. ^[3]

There is a wide range of sizes between all species of Longfengshania, with the largest specimens coming from the Longshan Formation, bearing blades up to 13 mm (0.5 in) long and stipes up to 20 mm (0.8 in) long. The smallest specimens come from the Doushantuo Formation, with blades up to 0.7 mm (0.0 in) or under in diameter. ^[3]
