Florentinia interrupta
Florentinia interrupta Duxbury, 1980
Holotype: Duxbury, 1980, pl. 12, fig. 3.
Locus typicus: Speeton Clay, Speeton, England.
Stratum typicum: Barremian
Original diagnosis: Duxbury, 1980, p. 121
A species of Florentinia with a spheroidal central body and fibrous processes which reflect a paratabulation of the formula 4", 6", 5""", 1"""". There are a variable number of parasulcal and paracingular processes. Ihe apical, precingular and postcingular processes typically taper towards their distal extremities and furcate into several capitate tubules. This furcation may occur at any point along the process length. The antapical process is usually somewhat longer than the others, does not furcate in the complex manner described above and always bears tubules near, but not at, the distal extremity. Paracingular and parasulcal processes are slender and taper distally to capitate tips. Again, these may furcate at any point along their length. The fibres of the processes coalesce on the central body to produce a crude microreticulum. The archeopyle is precingular, formed by detachment of paraplate 3".
Observed Dimensions: Holotype 70x73 Ám. Overall 86(75)68x81(74)65 Ám.
Affinities:
Duxbury, 1980, p. 121: This species differs from all others of the genus in having distinctly fibrous processes whose striations coalesce on the central body to produce a crude microreticulum.
