FIGURE 5. Microtomographic longitudinal sections focused on the posterior platform of Epigondolella vialovi, E. uniformis, and E. triangularis aimed to show the ontogenesis of the posterior node growing behind the cusp. For each section a 3D model of the correspondent conodont is provided. 1, E. vialovi; 2, E. uniformis; 3, juvenile specimen of E. uniformis from sample NA43 (from Mazza and Martínez-Pérez, 2015; repository number Micro-Unimi no. 2005); 4, E. triangularis; 5, juvenile specimen of E. triangularis from sample NA43 (from Mazza and Martínez-Pérez, 2015; repository number Micro-Unimi no. 2004). Scale bars equal 200 µm. Legend: cu, cusp; pn, posterior node; wm, white matter.
