Diagnosis

---|---|---|
K. A. v. Zittel 1890 | Sämmtliche Wirbel amphicöl oder platycöl; Bückenmarkcanal in der Sacral-
gegend enorm erweitert. Astragalus mit der Tibia verwachsen. Zweite Reihe des Carpus und Tarsus nicht verknöchert. Metatarsalia kurz. Hinterfuss dreizehig. Zehen mit breiten Hufen. Schwanz mit zwei bis vier Paar gewaltiger Hautstacheln besetzt. | |
B. F. Nopcsa 1901 | Jól kifejezett postorbitale. Intermaxillare fogatlan. Orrlyukak nagyok, igen elöl fekszenek. Koronanyujtvány nincsen, praeorbitalis nyílás kicsiny. Csigolyák amphicoelek; sacrumcsigolya számos. Az összes csont tömör. Pubis és processus pectinealis erösek. Plantigrad lábak pataalaku körmökkel. Erös börváz. A mellsö lábak vagy rövidebbek mint a bátsók, vagy velük majdnem egyformák. (Zittel szerint, rövidítve.)
[Well expressed postorbital. Intermaxillary toothless. Nasal openings large, very forward. No coronoid process, preorbital opening small. Vertebrae amphicoelous; sacrum vertebrae numerous. All bones are solid. Pubis and pectineal process are strong. Plantigrade legs with hooved nails. Strong dermal skeleton. The forelegs are either shorter than the hind legs or almost identical to them. (According to Zittel, abbreviated.)] | |
R. S. Lull 1924 | Small, elongated skull having no antorbital fenestra; nares large, anteriorly placed; toothless prernaxillary; teeth small, spatulate, with coarsely serrated margins; vertebrae amphicoelous or amphiplatyan, solid throughout, as are limb bones; postpubis not slender, nearly as long as ischium; neural canal greatly enlarged in sacrum, less so in brachial region of back; hind limbs much the larger, with straight, somewhat flattened femur; fore limbs robust and angulated; semi-plantigrade feet, pentadactyl, with first digits somewhat reduced, phalanges hoof-like; armor strongly developed into huge dermal plates and spines. | |
B. F. Nopcsa 1928 | base of cranium narrow; upper temporal vacuities present; condyle oblique; anterior limbs short; dermal bones keeled or plate-like | |
F. v. Huene 1948 | No preorbit; supra-orbital bone; all sides of teeth enamelled, broad low crown with serrated borders; short neck; enlarged neural canal in sacrum; short anterior leg; high olecranon ulnae; 5 digitigrad fingers in manus; ischium and pubis of equal length; tibia shorter than femur; pes plantigrad; crested dermal scutes and spines. Upper Jurassic to Lower Cretaceous. | |
S. C. R. Maidment et al. 2008 | All stegosaurs more closely related to Stegosaurus than to Huayangosaurus (Sereno 1998).
Unambiguous synapomorphies: • Transverse width of tops of anterior caudal neural spines greater than anteroposterior width • Ossified epaxial tendons absent (reversed in Stegosaurus mjosi) Additional synapomorphies using ACCTRAN: • Quadrate head strongly arched posteriorly in lateral view (equivocal in all members of Stegosauridae except Stegosaurus) • Alveoli of dentary tooth row not visible in lateral view due to the presence of a thin lateral lamina (equivocal in Dacentrurus) • Dorsal shield of sacrum is not perforated by foramina in between ribs (equivocal in Dacentrurus; reversed in Tuojiangosaurus) Additional synapomorphies using DELTRAN: • Dorsal process on transverse process of anterior caudal vertebrae present (equivocal in Huayangosauridae) • Distal ischial shaft has a distinct angle about midlength in lateral view (convergent in Gastonia and Sauropelta; equivocal in basal stegosaurs) |
