Numerical simulations predict the existence of old Tidal Dwarf Galaxies(TDGs) that would have survived several Gyr after the collision lying at theirorigin. Such survivors, which would by now have become independent relaxedgalaxies, would be ideal laboratories, if nearby enough, to tackle a number oftopical issues, including the distribution of Dark Matter in and aroundgalaxies. However finding old dwarf galaxies with a confirmed tidal origin isan observational challenge. A dwarf galaxy in the Virgo Cluster, VCC 2062,exhibits several unusual properties that are typical of a galaxy made out ofrecycled material. We discuss whether it may indeed be a TDG. We analysedmulti-wavelength observations of VCC 2062, including an IRAM CO map, an opticalspectrum of its HII regions, GALEX ultraviolet and archival broad-band andnarrow-band optical images as well as a VLA HI datacube, originally obtained aspart of the VIVA project. VCC 2062 appears to be the optical, low surfacebrightness counterpart of a kinematically detached, rotating condensation thatformed within an HI tail apparently physically linked to the disturbed galaxyNGC 4694. In contrast to its faint optical luminosity, VCC 2062 ischaracterised by strong CO emission and a high oxygen abundance more typical ofspiral disks. Its dynamical mass however, is that of a dwarf galaxy. VCC 2062was most likely formed within a pre-enriched gaseous structure expelled from alarger galaxy as a result of a tidal interaction. The natural provider for thegaseous tail is NGC 4694 or rather a former companion which subsequently hasbeen accreted by the massive galaxy. According to that scenario, VCC 2062 hasbeen formed by a past tidal encounter. Since its parent galaxies have mostprobably already totally merged, it qualifies as an old TDG.
