A ‘Problematic fossil’ revealed:Pycnoporidium ? eomesozoicumFlügel, 1972 (Late Triassic, Tethys)—not an enigmatic alga but a strophomenid brachiopod (Gosaukammerellan.g.)
The microproblematicumPycnoporidium ? eomesozoicumFlügel, 1972, from Upper Triassic reefs of the Alpine-Mediterranean region, Turkey Oman and Iran (originally interpreted as possible alga) represents the type species of a new strophomenid brachiopod genus (Gosaukammerellan.g.). The genus is characterized by a very small, millimeter-sized plano-convex shell, whose ventral valve is attached to the substratum (mainly sponges) by symmetrically arranged outgrowths developing from a pseudopunctate, lamellose foliated shell wall and composed of densely spaced subparallel ‘tubes’ comparable with productide spines secreted by papillose extensions of the mantle.Gosaukammerellaseems to be the only reliable candidate for the existence of post-Paleozoic strophomenid (productid ?) brachio
