Evidence from Recent plankton regarding the biological affinities of Tasmanites Newton 1875 and Leiosphaeridia Eisenack 1958

D. Wall
Published: 01 July 1962
Geological Magazine (1962) 99 (4): 353–362.
...D. Wall Abstract The genera Tasmanites (first described under the name Sporangites) and Leiosphaeridia have been considered as both spores and algae at various times. In comparison with Pachysphaera pelagica and Halosphaera minor, present-day species of green algae, it is concluded that Tasmanites...
