ROM 60079, composite interference image of part and counterpart, showing coarse stripes and fine striations

Bars preserved as dark two-dimensional regions lateral to the gills.

Model showing relationship between bars (brown, interpreted as being associated with muscle), gills (mauve), fins (cream), and axial cavity (blue). Model generated in Blender.

HK-MF-00002, Chengjiang specimen; axial cavity decimated by burrowing.

ROM 60117, Burgess Shale specimen with minimal burrowing, infill of axial cavity undisturbed

Canal narrows within the internal portion of the funnel.

Interference image, using images under direct illumination and crossed polars. Specimen with well-preserved soft tissue has smooth, unornamented tentacle margins. Robustly lined...

Fig 2d: ROM 60146 — Elemental distribution in eye and head of Nectocaris pteryx from the Burgess Shale

Complementary preservation of lineations: broad stripes are visible anteriad, fine striations posteriad. Assuming that this represents a single individual, the anterior portion...

Lateral specimen illustrating curved belt-like structure with serially repeated linear notches projecting radially.

Specimen with well-preserved soft tissue has smooth, unornamented tentacle margins; interference image under plane and crossed polars.
