McDermitt - Upper Bed Float / Additional Bed

I am told this is very rare material. One of these was specifically IDed as a float egg (i.e. found lose on the ground). The other one is unmistakably the same location. However I do not know whether these are from a known additional bed in the area or are curious strays. They have a very distinct appearance, with an inclusion rich matrix. They are also one of the few eggs where the agate regularly leaves certain areas of the core walls uncovered (cf. Jackrabbit Springs).
