Liesbergia
From Fensome et al., 2019:
Liesbergia, Berger, 1986, p.341.
Type: Berger, 1986, fig.3 (part), fig.5, nos.1–4, as Liesbergia liesbergensis.
---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Original description: [Berger, 1986]:
Diagnosis:
Cysts relatively large and bearing a precingular (P = 3" or 2P = 3" + 4") archeopyle. Ornamentation consists of small spines, more or less dense. Paratabulation standard gonyaulacoid. A very characteristic apical horn is formed by anastomosing fibres (cf. [Berger, 1986] Fig.3). In the apical area, a small vaulting is normally formed just under the horn (cf. [Berger, 1986] Fig.3).
Affinities:
Diacanthum filapicatum has great affinities with Liesbergia. However, the combined archeopyle and the more massive apical horn would put this species rather in a genus close to Liesbergia than in Liesbergia s.s.
