Europasaurus holgeri exhibits the following unambiguous autapomorphic states:[1] "nasal process of premaxillary projecting anterodorsally; medial notch is 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 width." In comparing Europasaurus with Camarasaurus,[1] Europasaurus differs "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." Other differences include Europasaurus shorter nasal-frontal contact and a parietal bone which is rectangular in posterior view. Unlike Camarasaurus, the neural spines of the presacral vertebrae are undivided. I
