FIGURE 5. Detail views of star-shaped tubercles and anastomosing line sculpture of Aponileus laikaae n. sp. 1. Medial part of glabella of holotype, SUI 129234 (see Pl. 3, figs 1, 4, 8, 10), x40. 2. Pleural region of thoracic segment, SUI 129246 (see Pl. 4, figs 10–13), x30. 3. Pygidial axis, SUI 129252 (see Pl. 5, figs 2, 3, 5, 7, 8), x40. 4.

FIGURE 3 in The Lower Ordovician (upper Floian) bathyurid trilobite Aponileus Hu, with species from Utah, Texas, and Greenland 3293
FIGURE 3. Single most parsimonious tree resulting from analysis of the matrix of Table 1. Length = 20; c.i. = 0.95; r.i. = 0.95. Open circles are characters containing homoplasy. Character optimizations are shown carried out under the ACCTRAN assumption. Upper values at nodes are Bremer support values. Lower values at nodes are bootstrapping GC scores.
