                            Description
                                    A comparison is carried out among the star formation histories of
early-type galaxies in fossil groups, clusters and low density
environments. Although they show similar evolutionary histories, a
significant fraction of the fossils are younger than their counterparts,
suggesting that they can be precursors of the isolated ETG galaxies.
