Possibly two different taxa here, the left one consisting of clearly bifurcating branches originating from a central point (Thallites sp. 1) while the right hand specimen has more of a webbed appearance with multiple points of origin (Thallites sp. 2).Thallites 1 has some similarities to the sterile foliage of Hymenophyllites macrosporangiatus Vakhrameev (Vakhrameev, 1952).
