Fig. 11 in Theropod tooth assemblages from the Late Cretaceous Maevarano Formation and the possible presence of dromaeosaurids in Madagascar
Fig. 11. Dendrogram drawn from the results of the cluster analysis. Statistical level of confidence for a node decreases toward the right (i.e., similarities between taxa increase toward the left). The results of the cluster analysis reveal that Morphotype 1 is very similar to Dromaeosaurus albertensis and Deinonychus antirrhopus while Masiakasaurus knopfleri (including Morphotype 2) is more similar to Saurornitholestes langstoni, Velociraptor mongoliensis, and Richardoestesia gilmorei. Morphotypes 1 and 2 are clearly different from Majungatholus atopus.
