We use semi-analytical modelling techniques to investigate the progenitor morphologies of present day ellipticals .
We find that , independent of the environment , the fraction of mergers of bulge dominated galaxies ( early-types ) increases with time .
The last major merger of bright present day ellipticals with M _ { B } \lesssim - 21 is preferentially between bulge dominated galaxies , while those with M _ { B } \sim - 20 have mainly experienced last major mergers between a bulge dominated and a disk dominated galaxy .
Independent of specific model assumptions , more than 50 \% 
of present day elliptical in clusters with M _ { B } \lesssim - 18 had last major mergers which are not of spirals as usually expected within the standard merger scenario .
