Sister taxa: SY pulchra gp, SY molischii gp, SY nodosa gp, SY mediterranea group, Syraco - fossil, S. sp.

Daughter taxa (time control age-window is: 0-800Ma)		Granddaughter taxa
	borealis type XCs elliptical discs, with a narrow rim, central part without conical depression. CFCs not differentiated.	S. borealis S. exigua S. pemmadiscus S. strigilis
	halldalii type Monothecate - no XCs. BCs with horizontal flanges and vertical tubes.	S. halldalii S. protrudens

First occurrence (base): at base of Gelasian Stage (0% up, 2.6Ma, in Gelasian stage). Data source: Total of range of species in this database

Plot of occurrence data:

Range-bar - range as quoted above, pink interval top occurs in, green interval base occurs in.
Triangles indicate an event for which a precise placement has been suggested
Neptune data: this is a higher taxon page so Neptune data is not plotted. For the customisable plot option go to a genus page Parent: Syracosphaera
