Abstract: In this poster a quantitative comparison of low and high-redshift supernovae by means of spectral indicators is presented. Measurements of Ca II H&K expansion velocity and equivalent width-like measurements of 12 highredshift supernovae (0.212 < z > 0.912) are found statistically consistent with those of nearby supernovae. One of the supernovae in our dataset, SN 2002fd (z=0.279), shows spectral characteristics similar to peculiars SN 1991T/SN 1999aa.
