Final Epithet

Bowmania prinsii (Perch-Nielsen, 1979) Varol, 2025a

Basionym

Micula prinsii Perch-Nielsen, 1979

Remarks

Stellate species of Bowmania exhibit a small cubiform central structure with a cross and protruding arms featuring small furcations. The blocks of Bowmania prinsii display parallel extinction with length-slow (+) elongation. The central cross also shows parallel extinction, but the elongation direction varies among specimens. Central cross with length-slow (+) elongation, as seen in Plate 32, Figure 22 (in Varol, 2025a), and those with length-fast (-) elongation, as shown in Plate 32, Figures 14-15 (in Varol, 2025a), were observed.
