Massive (M_{stellar}≥10^{11} h_{70}^{-2} {M}_{&sun;}) galaxies are privileged probes to explore galaxy evolution, as their high luminosities allow us to track them over a large span of cosmic time. They suffer dramatic modifications in their sizes, star formation histories and number densities from high to low redshift. This must be also reflected in their structural parameters and thus we present here how their Sérsic indices and visual morphologies change since z = 3. This has been confirmed by analysing the rotational support for 10 of these objects at z = 1.4. Future large area and deep surveys as UltraVISTA will unveil the relation of this galaxy population with their lower mass companions, and hence constraining the ΛCDM paradigm.
