Thallophycoides is an undifferentiated, globular, non-mineralized alga from the Ediacaran period, found within the Doushantuo Formation in 1992.[2][3]
Description
Thallophycoides phloeatus is a globular alga growing up to 800–1,500 μm (0.03–0.06 in) in length, which lacks any notable cell or thallus differentiation. Due to this, it has been postured to be either an early or stem group florideophyte red algae.[3][4] The cells are spheroidal to ellipsoidal in shape, and are tightly packed together.[4]
Thallophycoides was most likely a benthic alga, inferred from how its lobate protrusions and tissues grew.[4]
