Got a snall sample of so-called "star sand" from Taketomi,Okinawa,Japan, that was loaded with some of (I think) the most beautiful forams: 99% of the sample consists of 2 species, Baculogypsina sphraerulata & Calcaroides spengleri; Went thru my inventory of forams & found some examples of their fossil kin: unfortunately, like any other fossil, the Miocene & Cretaceous ones have suffered a lot of wear & tear, but hopefully you'll be able to view & compare. Don't know if the images do them justice. Each foram is about the size of a grain of sand.
