Fig. 2.13 Botryococcus algal remains
Botryococcus braunii (Kützing) (Blackburn 1936) (Fig. 2.13).
Occurrence: Very rare. Muja No. 1 Bore; 1126-1130
Remarks: Botryococcus is
found in fresh to brackish water. Highly resistant to degradation (see discussion
in Part I).
Anteturma: Sporites (Potonie 1893).
Turma: Triletes (Potonie and Kremp 1954).
Subturma: Perinotriletes (Dettmann 1963).
Genus Zinjisporites (Hart 1963).
Diagnosis: Cavate. Heavily ornamented trilete spores. Amb. triangular to roundedtriangular. Laesurae usually indistinct. Sculpture consists of baculae which
coalesce at their bases to simulate a zona.
Known distribution: Lower Permian (Artinskian) of Tanganyika (Hart 1963). Similar forms were described by Balme and Hennelly from the Permian of New South
Wales under Verrucosisporites bullatus.
Remarks: The description of Zinjisporites by Hart conforms with spores found
in Collie–Muja. This spore is so abundant in some samples so as to yield good
specimens for a detailed description. The cavate appearance is often obscured by
the heavy sculpture of the ektexine.
Zinjisporites eccensis (Hart 1963) (Fig. 2.14).
Occurrence: Lower Permian (Artinskian?) of Collie–Muja Basins; Site B
bore/1641
; Muja Site D bore/1847
