Description
My take on what the complete forelimb of Megaraptor might look like. This is a composite from specimens MUCPv-341 and MUCPv-595 meant to represent the proportions of MUCPv-341, a 1000 kg adult.
From this restoration, MUCPv-595 would be at the scale of a 23.2 cm humerus (preserved) with a 14.8 cm radius (estimated) and the holotype specimen MCF-PVPH 79 would be at the scale of a 33.2 cm ulna (preserved) with a 43.2 cm humerus (estimated).

Remarks:

-Humerus length is greater than usually depicted in the primary megaraptoran skeletals on DeviantArt (-> , -> ), which, given available measurements for other bones, end up at less than 39 cm for the adult Megaraptor specimens.
I am not aware of any way to replicate such proportions, while the humerus length shown here is easily reached by applying MUCPv-595's ratio of pectoral girdle/humerus length to MUCPv-341's pectoral girdle. The radius and ulna of MUCPv-341 also appear to fit rather well into their condyles on a 58 cm humerus, certainly moreso than a <39 cm humerus.

NOTE: I do not own the reconstructions used here. As the image says, all credit goes to Porfiri et al. (2014) for the humerus and GetAwayTrike for the remainder.
