In the picture, notice the six-armed Contrast Colony shapes vary. Fossil Coral for sale. If you look at the fossil in detail you can see the many tiny pores or holes (called corallites) where the coral animals (polyps) lived when the coral was alive. Their distinguishing feature is their well-developed horizontal internal partitions (tabulae) within each cell, but reduced or absent vertical internal partitions (septa).
