Sthenurine forelimbs had long fingers and claws with small, stiff arms of modern macropods. Sthenurine forelimbs were long . They had wo extra-long fingers and claws. Modern macropods have relatively small, stiff arms. Sthenurine forelimbs were long. They had two extra-long fingers and claws compared with the smaller, stiff arms of today's macropods. Sthenurine forelimbs were long. They had two extra-long fingers and claws. In contrast, modern macropods have relatively small, stiff arms. Sthenurine forelimbs have two long fingers and claws. Modern macropods have small, stiff arms in comparison to those of the Sthenurine. Sthenurine forelimbs were long with two extra-long fingers and claws. They are different from the relatively small, stiff arms of modern macropods. Stenurine forelimbs have been long with two extra-long fingers and claws compared to the relatively small, stiff arms of modern macropods.
