Spiniferites grallaeformis
Spiniferites grallaeformis (Brosius, 1963, p.42, pl.5, fig.3; text-fig.2) Strauss et al. 2001, p.412.
Combination not validly published: basionym not fully referenced.
NOW Achomosphaera. Originally Hystrichosphaeridium, subsequently (and now) Achomosphaera, thirdly Spiniferites (combination not validly published).
Taxonomic junior synonym: Spiniferites solidago, according to Strauss et al. (2001, p.412).
Holotype: Brosius, 1963, pl.5, fig.3.
Age: Oligocene.
Original diagnosis: Brosius, 1963, p.42: Hystrichosphaeridium grallaeformis
The round, two-layered capsule bears hollow, furcate processes, resembling those of H. ramuliferum. Ends often open or bearing little thorns. Processes build up by outer membrane. Bases of processes stilt-rood shaped, may be joined, wide and thin processes possible on one specimen. Both wall layers regulary perforate.
Dimensions: Capsule diameter (without processes) 40µm, length of processes 17µm. Number of processes c.20.
Combination not validly published: basionym not fully referenced.
