This beautifully preserved sponge is virtually complete. This famous chalk quarry is no longer accessible to the collector. These rare sponges from this location are becoming increasingly difficult to obtain. A lovely drawer fossil.
Although technically this is not a fossil, it has come to be, by the same process of fossilisation. The specimen consists of two 10mm square crystals of rock salt (Halite), which have been dissolved and then sediment has re-filled the space left by the crystals so forming this unusual pseudomorph. A really unusual and "quirky" piece.
The farringdon sponge bed is world famous for its fossil sponges and this is a particularly fine example. The sponge is totally three dimensional and has the characteristic orange colour as with all of these. A superb drawer specimen.
