A prominence on the preaxial border at the proximal end of the forelimb was found to appear in a limited period of limb development in mouse embryos. This prominence is observable around day 11 (vaginal plug = day 0). When compared with the number of tail somites, this prominence first appears in embryos with 10–12 tail somites, becomes prominent in embryos with 14–18 tail somites, and disappears in embryos with 20–22 tail somites. This prominence may be utilized as a simple morphological indicator for staging developing mouse forelimb.
