Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| P. M. Sander et al. 2006 | Europasaurus holgeri gen. et sp. nov. shows the following unambiguous autapomorphies (see also Supplementary Information): nasal process of premaxillary projecting anterodorsally; medial notch on posterior dorsal margin of cervical vertebral centra; scapular acromion with a prominent posterior projection; and transverse width of astragalus twice its dorsoventral height and anteroposterior length. Europasaurus differs from Camarasaurus in the wing-shaped posterior process of the postorbital being slightly
longer and wider than the anterior process, whereas it is much shorter in Camarasaurus. Europasaurus also differs from Camarasaurus in its short nasal–frontal contact; rectangular parietal in posterior view; and undivided presacral neural spines. Europasaurus differs from Brachiosaurus in the shorter muzzle, quadratojugal contacting squamosal; participation of jugal in ventral margin of skull; short nasal–frontal contact; and humerus flat anteromedially with proximal and distal epiphyses not aligned. Europasaurus differs from Lusotitan atalaiensis in the shape of the ilium and the astragalus, and from the potentially valid ‘Cetiosaurus’ humerocristatus in its shorter and less prominent deltopectoral crest. Europasaurus differs from almost all known neosauropods in its diminutive adult body size. |
