Original Description
Extra details from original publication
Finlay described this species as follows: " ... like aragonensis...but has only four or five chambers per whorl, a sharp keel, and a practically flat top."" No figure was given. The type locality is F5570, chalk marls below Amuri Stone, Hurunui River, one-half mile southwest of Trig. B (Lowry Peaks S. D.); Heretaungan stage (Lower Eocene). The specimens later figured by Finlay as Globorotalia crater (F567J, S68/20I, base of sandy mar! separating greensands from the chalk marls, 30 chains northwest of the Middle Waipara gorge, left bank) are from older beds that are of Waipawan or Mangaorapan age (Paleocene-Lower Eocene), and are not typical. They differ from Globorolalia crater sensu stricto in being smaller, without a wide-open umbilical depression, and in having a more prominent flange. Globorotalia crater, with its wide, deep umbilicus, squarish shape, and prominent ornamented dorsal sutures, is almost identical with the species figured as Globorotalia velascoensis Cushman by Hamilton (1953, pl. 30, figs. 16-18) from mid-Pacific seamounts."
