FIGURE 1 in Should the terms 'basal taxon' and 'transitional taxon' be extinguished from cladistic studies with extinct organisms?
FIGURE 1. Simplified cladogram showing the relationships of the three main lineages of dinosaurs with focus on Sauropodomorpha. Letters A - F are related to clades treated in the main text. The assumed ages for the taxa of the tree are represented by rectangles thicker than other branches. Cladogenetic events (dichotomies) are not calibrated against geological time. Ornithischia is represented by the following taxa: Pisanosaurus, Heterodontosauridae, Eocursor, Thyreophora, Neornithischia. Theropoda is represented by the following taxa: Tawa, coelophysoids, Ceratosauria, Tetanurae. All other taxa represent Sauropodomorpha (here following the definition of Galton and Upchurch, 2004). Sauropoda (here following the definition of Salgado et al., 1997) is represented by Vulcanodon, Tazoudasaurus, Spinophorosaurus, Neosauropoda.

Fig. 14. A synthesis of main conodont events against other biotic and tectonic events, carbon isotopic curve and sea−level changes. Note a response of relative conodonts size to variation in δ13C curve. The essential biofacies turnovers, a sequence of conodont crisis and recovery episodes correlate positively with sea−level and productivity fluctuation.
