Description(s)
Jamison-Todd et al., 2025a:
Diagnosis. Boring with chamber diameters ranging from 1.1–2.3mm and total depths 1.4–2.6mm. Aperture is fine and straight, with the threadlike aperture neck leading to a chamber that sits at mid-depth beneath the surface of the bone. Chambers have a wide arc and a globular, regular appearance, with symmetry radiating from the upper chamber. Branches are very short and rounded, merging with and almost indistinct from the main chamber body.
