TABLE 3. Measurements of the best-preserved specimens (in cm) of the forelimb of the titanosaurian sauropod Lirainosaurus astibiae from the Late Cretaceous of Laño (northern Spain). The measures with a ? symbol are approximate as iron oxides cover the surface of the bones. Abbreviations: **: eroded proximal and/or distal ends; Dist. Prx-D dpc: distance from proximal end to distal end of deltopectoral crest; Max. Φ: maximum diameter in the narrowest part of the diaphysis; MDW: maximum width of the distal end; Min. Φ: minimum diameter in the narrowest part of the diaphysis; MPW: maximum width of the proximal end; Per: perimeter in the narrowest part of the diaphysis; RI = average of the greatest widths of the proximal end, mid-shaft and distal end of the element/length of the element (Wilson and Upchurch, 2003).

Abbreviations: **: eroded proximal and/or distal ends; ECC = femoral mid-shaft width/femoral anteroposterior width (Wilson and Carrano, 1999); Max. Φ: maximum diameter in the narrowest part of the diaphysis; Max. MLW D/Prx: maximum mediolateral width of the distal/proximal end; MDW: maximum width of the distal end; Min. Φ: minimum diameter in the narrowest part of the diaphysis; MLW: mediolateral width; MPW: maximum width of the proximal end; Per: perimeter in the narrowest part of the diaphysis; RI = average of the greatest widths of the proximal end, mid-shaft and distal end of the element/length of the element (Wilson and Upchurch, 2003).
