Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| S. C. R. Maidment et al. 2008 | Stegosaurus, Ankylosaurus, their most recent common ancestor and all of their descendants (Sereno 1998).
Unambiguous synapomorphies: • Quadrate lateral ramus absent • Prominent, ring-like cingulum present on maxillary teeth (reversed in Gastonia and Huayangosaurus) • Absence of teeth in premaxilla (reversed in Huayangosaurus; equivocal in most stegosaurs) • Atlantal neural arch fused to intercentrum in adults (reversed in Stegosaurus mjosi) • Prezygapophyses fused on some dorsal vertebrae • Manual and pedal unguals hoof-shaped (semi-circular in dorsal view; dorsoventrally compressed) • Anterior iliac process projects at an angle that diverges widely from the parasagittal plane (reversed in Huayangosauridae) • Ventral flange backing acetabulum absent (reversed in Kentrosaurus) • Posterior end of ischium not expanded relative to the shaft • Anterior trochanter of femur fused to greater trochanter in mature individuals Additional synapomorphies using ACCTRAN: • Premaxillae have a broad U or V-shaped notch where they meet on the midline in dorsal view (reversed in Huayangosaurus) • Dorsal surface of the distal ischial shaft has a distinct angle about half way along (reversed in Dacentrurus and Euoplocephalus) • Acetabular portion of the pubis faces wholly laterally (reversed in Sauropelta) • Loss of pedal digit I (reversed in Sauropelta) • Pedal digit IV has three or fewer phalanges (reversed tostate ‘1’ in Sauropelta) |
