Cordosphaeridium delimurum
Cordosphaeridium delimurum, Fensome et al., 2009, p.23, pl.2, figs.l–q.
Holotype: Fensome et al., 2009, pl.2, figs.l,p.
Age: early Lutetian (Middle Eocene).
-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Original description: [Fensome et al., 2009]:
Diagnosis:
A species of Cordosphaeridium with tubular processes that are variable in their terminations but typically irregularly branched; the process walls are fibrous but solid. The wall of the central body is about 1 μm or less thick.
Dimensions:
Maximum diameter of central body 37(51)62 μm, length of processes up to 20(24)27 μm; 3 specimens measured.
Holotype: maximum diameter of central body 62 μm, length of processes up to 27 μm.
Affinities:
Cordosphaeridium delimurum is similar to both Cordosphaeridium inodes and Cordosphaeridium gracile, but has a thin central body wall in contrast to the distinctly thick wall of those two species. The process walls are solid, not with gaps between fibres as in Cordosphaeridium fibrospinosum.
