Tergestiella adriatica

Classification: ntax_cenozoic -> Mesozoic Survivors -> Watznaueriaceae -> Tergestiella -> Tergestiella adriatica
Sister taxa: T. adriatica


Citation: Tergestiella adriatica Kamptner, 1941
Rank: Species
Taxonomic discussion: The extant species appears to be distinct from the fossil species such as C. margerelii and C. reinhardtii although they all appear to belong to the same genus. The structure is identical to that of fossil Watznaueriaceae

Distinguishing features: Tergestiella species with the tube core elements forming a flat surface on the distal shield from which the inner tube elements protrude as a central cone. Pores occur both at the centre of the cone and between the tube core and distal shield elements. - Hagino et al. (2015).

Farinacci & Howe catalog pages: T. adriatica *

Ecology & Biogeography: The only known occurrences are from Rovinj, Croatia and Tomari Japan - both warm water shallow marine settings. At Tomari occurrence of the coccospheres in the water column is highly seasonal occurring regularly in late June, accompanied by Braarudosphaera - Hagino et al. (2015).

Phylogenetic relations: Molecular genetic analysis showed that T. adriatica is deeply divergent from all other sequenced coccolithophores, supporting the inference from the fossil record that the Watznaueriales diverged in the Early Jurassic and are not ancestral to any of the well-known groups of modern and Cenozoic coccolithophores. - Hagino et al. (2015).
