Figure 1. Cochlear anatomy and visualization of methods. (a) Three-dimensional rendering of the cochlea (shown as right) of Balaenoptera acutorostrata in apical view. (b) Same, virtually transected along the modiolus (mod) showing the primary and secondary bony laminae (bl1 and bl2, respectively). (c) Radii ratio method as applied in this study: circles superimposed onto basal and apical turns of a 2-D projection of the path tracing the basilar membrane within the cochlea. Dots represent three points on each circle for calculation of the respective radius. (d) Landmark-based geometric morphometrics: 3-D resampled path with landmarks 1 to 40. ... : Published as part of Ritsche, Indira S., Fahlke, Julia M., Wieder, Frank, Hilger, André, Manke, Ingo & Hampe, Oliver, 2018, Relationships of cochlear coiling shape and hearing frequencies in cetaceans, and the occurrence of infrasonic hearing in Miocene Mysticeti, pp. 33-45 in Fossil Record 21 (1) on page 36, DOI: 10.5194/fr-21-33-2018, http://zenodo.org/record/10965492 ...
