Dacentrurinae Mateus, Maidment & Christiansen, 2009 (nomen cladi conversum)

Registration number.

1099.

Phylogenetic definition.

The largest clade containing Dacentrurus armatus Owen, 1875 but not Stegosaurus stenops Marsh, 1887 . This is a maximum-clade definition.

Reference phylogeny.

Figure 5 of this paper is designated as the primary reference phylogeny. Additional reference phylogenies include figure 3.14 of Carpenter et al. (2001), figure 16.11 of Galton and Upchurch (2004), figure 8 of Maidment et al. (2006), figure 3 of Escaso et al. (2007 a), figure 11 A and 12 A of Maidment et al. (2008), figure 1 of Mateus et al. (2009), figure 1 of Maidment (2010), figure 1 and 2 of Raven and Maidment (2017), figure 6 A of Hao et al. (2018), figure 12 of Maidment et al. (2020), figure 8 of Dai et al. (2022), figure 6 of Jia et al. (2024), figure 15 of Li et al. (2024 a), figure 8 of Li et al. (2024 b), figure 7 of Li et al. (2024 c), and figure 12 of Zafaty et al. (2024).

Composition.

According to the primary reference phylogeny, the clade Dacentrurinae comprises Al. longispinus , K. aethiopicus, Th. atlasicus , Ad. boulahfa , and D. armatus .

Comments.

Dacentrurinae was first (informally) defined by Mateus et al. (2009). This is formalized using the same type of definition but replacing S. armatus Marsh, 1877 with S. stenops as external specifier. The species S. armatus was originally designated as the type species of the genus Stegosaurus , but it was later replaced by S. stenops as the type ( International Commission on Zoological Nomenclature 2013). Figure 5 of this paper has been designated as the primary reference phylogeny because it considers the latest taxonomic revisions, includes the highest number of stegosaurian OTUs, and provides a high-resolution topology.

Figures

Figure 5. Chronogram showing temporal, palaeogeographical, and phylogenetic relationships of stegosaurian dinosaurs. Single MPT with a length of 194 steps. CI = 0.660 and RI = 0.799. The extremely fragmentary Mongolostegus exspectabilis Tumanova & Alifanov, 2018 was excluded a priori. Bremer Support values above (not showed values under 2) and Standard Bootstrap values below (not showed values under 50). The MPT was scaled in time a posteriori using the function ‘ bin _ timePaleoPhy’ of the package ‘ paleotree’ (Bapst 2012) in the R library (R Core Team 2023). Silhouettes obtained from PhyloPic.
