The most massive super-AGB stars are candidate progenitors for type II core-collapse SNe. We discuss the two supernovae, SN1980K and SN2003gd that provide some restrictions on the upper mass limit of super-AGB stars.6 pages, 2 figures for the proceedings of the 7th Torino Workshop on Nucleosynthesis in AGB starsAstrophysicstext
