Material.
SM2011-1-001 (renumbered from KPS2- 1 in Buffetaut et al. (2001)), a single posterior dorsal vertebra (Fig. 3A View Figure 3 ).
Locality and age.
Ban Khok Sanam locality, Kham Muang District, Kalasin Province; the lower Phu Kradung Formation, Late Jurassic.
Previous study.
This the first evidence of a thyreophoran dinosaur in Southeast Asia. The specimen is identified as belonging to the family Stegosauridae , which is more advanced than primitive taxa, such as huayangosaurid Huayangosaurus from the Middle Jurassic of China ( Buffetaut et al. 2001). The specimen has a much higher neural arch and more upright transverse processes, indicating that it should be referred to the Stegosauridae ( Buffetaut et al. 2001).
Comments.
The anterior part of the centrum and the neural arch of SM2011-1-001 has been destroyed, but likely to possess centra of the dorsal vertebrae longer than wide as most stegosaurians, except for Miragaia longicollum ( Maidment et al. 2008; Mateus et al. 2009).
