Description

Test shape elongate, cylindrical, somewhat tapering, slightly nodular, more so in the latest chambers, initial end rounded, distinctly curved, rarely almost straight. Length of test 3–4 mm, the largest 5 mm; test width 0.4–0.6 mm. Chambers subglobular, sometimes slightly cylindrical in later chambers, rectilinearly arranged, embracement minimal, distinctly to slightly curved; number of chambers usually 4–7, at most 9. In microspheres, the initial 3–5 chambers are wound in about half of an evolute planispiral ( Fig. 3A ). Sutures horizontal. About 90% of the specimens have a basal knob or short spine, exterior otherwise smooth. Secondary surface laminations cover the whole test (ortho-lamellar) or only part of the test (plesio-lamellar). Aperture radial, nearly central, slightly raised or protruding, with up to 12 symmetrically arranged tines, that are fused in the center. Wall thick and finely perforated.

Remarks

Of the 1364 examined specimens of D. elegans , 6 were microspheres. Diameter of proloculus in the megalospheres is 0.2–0.4 mm, but <0.05 mm in the microsphere. Dentalina elegans was tacitly considered to be a megalospheric form of D. frobisherensis ( Grønlund & Hansen 1976) , since the morphology of the adult chambers is very similar. The species Dentalina baggi was distinguished from Dentalina elegans ( Eiland & Guðmundsson 2004) , stating that the test of the former had less inflated chambers, and that it lacks a prolocular spine, but noted though that about 10% of D. elegans also had no prolocular spine. The added material from the BIOICE renders this distinction arbitrary for the material at hand, as variation in test width and chamber inflation overlaps in specimens with or without a prolocular spine. It seems that forms identified here as D. elegans are relatively common in the North Atlantic and may have been reported under several names. The species Nodosaria advena , first described by Cushman (1923) off the northeast coast of USA seems to have a nearly identical morphology as the present D. elegans but differs only in being much larger viz up to 7 mm in length. Specimens under the name Nodosaria advena have been reported from the North Sea ( Gabel 1971), off Scotland and the Faroe Islands ( Cushman 1923) and in Late Quaternary deposits in the Oslofjord area, Norway ( Feyling-Hanssen 1964).
