Polysphaeridium flexuosum
Polysphaeridium "?flexuosum" (Davey et al., 1966, p.169, pl.2, fig.5) Below, 1982c, p.28. Emendation: Sarkar and Singh, 1988, p.39, as Cleistosphaeridium flexuosum. Holotype: Davey et al., 1966, pl.2, fig.5; Fauconnier and Masure, 2004, pl.23, fig.8. NOW Downiesphaeridium. Originally Cleistosphaeridium?, subsequently Polysphaeridium?, thirdly Cleistosphaeridium, fourthly (and now) Downiesphaeridium. Questionable assignment: Below (1982c, p.28). Age: Cenomanian.
Original diagnosis: Davey et al., 1966, p.169: Cleistosphaeridium flexuosum
Central body subsphaerical to elongate, bearing numerous, broadly acuminate, processes. All processes of approximately same length, slightly fibrous and always flexuous.
Original description: Davey et al., 1966, p.169: Cleistosphaeridium flexuosum
The most distinctive feature of ?C. flexuosum is the flexuous nature of the broad fibrous processes. The nature of the surface of the central body is difficult to determine and the presence of an archaeopyle has not been recorded.
Affinities:
Davey et al., 1966, p.169: Cleistosphaeridium flexuosum
The nature of the processes easily differentiate ?C. flexuosum from all other previously described species.
