Citation: Canistrolithus Jordan & Chamberlain, 1993
taxonomic rank: Genus
Type species: Canistrolithus valliformis Jordan & Chamberlain, 1993

Distinguishing features:
Parent taxon (Alisphaeraceae): Heterococcoliths asymetric, arranged in meridional rows on coccosphere; V-unit forms flange, R-unit basal. Also nannolith phase "Polycrater" with quadrate aragonitic liths.
This taxon: Coccoliths elongate oblong muroliths with asymmetric distal flange

Farinacci & Howe catalog pages: Canistrolithus *


Monothecate, coccoliths are elongate, oblong, muroliths with an asymmetric distal flange. Outer tube wall elements show weakly anticlockwise imbrication; inner tube wall elements vertical. In comparison to Alisphaera, there is no proximal flange or grill and the tube is higher, but basic structure appears similar (Kleijne et al. 2002).
