Fig. 5 in Rediscovery of an internal organ in heart urchins (Echinoidea: Spatangoida): morphology and evolution of the intestinal caecum
Fig. 5 Occurrence of the intestinal caecum in heart urchins (Echinoidea: Spatangoida). a An intestinal caecum is found only in the Schizasteridae (Spatangoida: Paleopneustina). b Distribution of the intestinal caecum among schizasterids. Both phylogenetic trees show the results of an analysis based on morphological characters (Stockley et al. 2005). The three genera mentioned as incertae sedis were not part of the cited phylogenetic study.

Figure 5 in Evolution and functional morphology of the frontal sinuses in Bovidae (Mammalia: Artiodactyla), and implications for the evolution of cranial pneumaticity
Figure 5. Digital reconstructions from computed tomography (CT) scan data of the skulls of Tetracerus quadricornis (A–B; YPM 7396) and Boselaphus tragocamelus (C–D; AMNH 22842, image reversed), illustrating frontal sinuses and related anatomy.
