Canningia senonica
Canningia senonica, Clarke and Verdier, 1967
Holotype: Clarke and Verdier, 1967, pl.1, fig.12
Locus typicus: Culver Cliff, Isle of Wight, England
Stratum typicum: Senonian
-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Original description: [Clarke and Verdier, 1967, p.21]:
Diagnosis:
A species of Canningia with a small apical and frequently two small antapical protrusions. The sculpture consists of a fine, irregular reticulum.
Description:
Shape of body rounded with small apical and sometimes antapical protrusions.
The apical archaeopyle is well displayed on most specimens which are incomplete having lost their apical part.
Sculpture of thin irregular processes up to 12 µm long which join distally to form an incomplete and irregular reticulum; the sculpture completely covers the body.
Dimensions:
Range: overall length 60-85 µm, overall breadth 50-70 µm, process length 6-12 µm.
Affinities:
C. senonica differs from C. reticulata in the possession of a higher reticulum, from C. colloveri and C. ringnesii in the presence of a reticulum, from C. rotundata in the absence of discrete processes.
