In this paper we define and study self-similar rankedfragmentations. We first show that any ranked fragmentation is theimage of some partition-valued fragmentation, and that there is infact a one-to-one correspondence between the laws of these twotypes of fragmentations. We then give an explicit construction ofhomogeneous ranked fragmentations in terms of Poisson pointprocesses. Finally we use this construction and classical resultson records of Poisson point processes to study the small-timebehavior of a ranked fragmentation.
