Examples

  • Its length, slender proportions and particularly prominent deltopectoral crest show that it is a brachiosaurid and, among brachiosaurids, its particularly long deltopectoral crest makes it unique and diagnosable.

  • The new taxon is characterized by a plate-like medial process of the scapula, a prominent proximal expansion of the deltopectoral crest of the humerus, a strongly inclined distal articular surface of the radius, and a proximally and laterally hypertrophied proximal metacarpal I. Phylogenetic analysis recovers

  • This relationship is supported by four unambiguous synapomorphies: height of neural arches subequal to or greater than the centrum height (Character 164: 0→1); minimum scapula width less than 20 percent its length (Character 200: 1→0); length of deltopectoral crest extends between 30 and

  • In many basal sauropodomorph taxa, the proximal margin of the deltopectoral crest is offset sharply from the proximal articular surface; however, all other taxa lack the accompanying proximal expansion present in

  • The anterior edge of the deltopectoral crest is rugose, with a straight proximodistally directed margin.

  • The deltopectoral crest is prominent, extending anteriorly from the anterolateral edge of the humerus, and extending approximately 50% of the length of the humerus.

  • The deltopectoral crest extends less than half the length of the element, with the distal origin located proximal to the middle of the shaft.

  • Scapular blade forming a 45° angle with coracoid articulation; humeral distal condyles exposed on anterior of shaft; stout ulna; humeral deltopectoral crest markedly expanded distally; elliptical femoral mid-shaft cross-section; distal condyles of femur bevelled dorso-medially; astragalar posterior fossa undivided
