As for the genus. Of the 245 spheres measured. 67% have diameters be tween 3.1 and 5 μm. Table 1 summarizes morphologic characteristics of the taxon.
The fossiliferous outcrops occur 2,900 m below the lowest metazoan trace fossils, are younger than 1.7 b.y. and are correlated to the Apache Group of Arizona, bracketed between radiometric ages of 1.2 and 1.4 b.y.
