Sphenolithus puniceus Bergen & de Kaenel in Bergen et al., 2017
Medium to large size, dome shape sphenolith having very high birefringence displaying first order blue to red interference colours at its plan and lateral view.
Sphenolithus puniceus differs from Sphenolithus moriformis (Brönnimann & Stradner, 1960) Bramlette & Wilcoxon, 1967 and Sphenolithus grandis Haq and Berggren, 1978 by very high birefringence. It is further distinguished from Sphenolithus moriformis by its larger size.
