Nannotax3 - ntax_non_cocco - Scrippsiella regalis

Scrippsiella regalis


Classification: ntax_non_cocco -> Dinophytes -> Thoracosphaeraceae -> Tangential wall -> Scrippsiella -> Scrippsiella regalis
Sister taxa: S. crystallina, S. lachrymosa, S. minima, S. patagonica, S. precaria, S. rotunda, S. sweeneyae, S. trifida, S. triquetracapitata, S. acuminata, S. regalis, S. fragments, S. sp.

Distinguishing features:
Parent taxon (Scrippsiella): Cysts with tangential wall structure and compound archaeopyles. Wall formed of largish non-intelocking elements each with a spine
This taxon: Like S. acuminata but spines longer and sutures between elements more complex
