LOT 1721
Natural History - Rastellum Fossil Bivalve
JURASSIC PERIOD, CIRCA 155 MILLION YEARS B.P.
2 3/8 in. (105 grams, 61 mm).
A Rastellum carinatum fossil bivalve; held in a card collector's tray. [No Reserve]
ProvenanceFrom Madagascar.
Ex Cambridgeshire, UK, collection.
Rastellum carinatum specimens have wide, angled ribs that have led to it being called the 'denture clam'; the zig-zag join between the two shells stopped coarse dirt and debris entering the shell and damaging its soft body. Like modern oysters, it lived in shallow coastal waters including the interstitial zone and fed on food particles that it filtered out of the sea water.
