We present observations of the FRI radiogalaxy 3C66B during a joint EVN + MERLIN VLBI session in May 1995. The jet is mapped from the 5 mas scale up to about 3 arcmin. The newly mapped VLBI jet shows essentially two elongated blobs in the direction of the brightest kpc jet (NE). We interpret these two blobs in the light of a new model for VLBI jet making use of the two-fluid concept.
