A modular wall block is adapted for being assembled together with a number of like blocks in stacked courses to form a retaining wall. The wall block includes a front face and rear, top and bottom, and opposing sides. A locking shear key extends outwardly from either of the top or bottom of the wall block, and is adapted for residing between respective adjacent sides of like blocks in an adjacent upper or lower course to anchor the wall block in position. A severable area is formed with the shear key for being removed to accommodate placement and orientation of the wall block between respective adjacent sides of like blocks in an adjacent upper or lower course.
