Abstract.

It is demonstrated that abundance patterns in extremely metal-deficient stars with [Mg/H] \(\lesssim\) -2 are remarkably similar to those seen in the individual first generation supernova remnants. This suggests that most of the stars with [Fe/H] \(\lesssim\) -2.5 were made from individual supernova events.
