Fig. 4 in Isolated theropod teeth from the Middle Jurassic of Niger and the early dental evolution of Spinosauridae

Fig. 4. Dendrogram obtained from the cluster analysis of the theropod teeth. A. Database from Hendrickx and Mateus (2014) and the HB site. The characters used were those proposed by Hendrickx and Mateus (2014) for lateral teeth. HB samples are clustered with Afrovenator and Dubreuillosaurus (black dot). B. Database from Hendrickx and Mateus (2014), the specimens from the HB site, and two basal spinosaurid teeth from the Middle Jurassic TP4 site in Niger (Serrano-Martínez et al. 2015). MUPE HB-118, MUPE HB-125, and MUPE HB-142 remain clustered with Afrovenator and Dubreuillosaurus (black dot), but MUPE HB-87, MUPE TP4-2, and MUPE TP4-3 are clustered with the spinosaurids (white dot).
