To constrain the conditions for very early nucleosynthesis in the Universe we compare the chemical enrichment pattern of an extremely metal-poor damped Lyman α (DLA) absorber with predictions from recent explosive nucleosynthesis model calculations. For this, we have analyzed chemical abundances in the DLA system at $z_{{\rm abs}}=2.6183$ toward the quasar Q0913+072 ($z_{{\rm em}}=2.785$) using public UVES/VLT high spectral resolution data. The total neutral hydrogen column density in this absorber is log N(H
