Natural History - Fossil Megalodon Giant Shark Tooth
Pliocene Period, circa 5.2-2.5 million years B.P.Sold for (Inc. bp): £143
A Carcharocles megalodon tooth displaying good polished enamel. 123 grams, 97 mm
From a Lincolnshire, UK, collection. Property of a Cambridgeshire, UK, gentleman.
Carcharocles megalodon is regarded as one of the largest and most powerful marine predators in vertebrate history and likely had a profound impact on structuring of the marine communities. Fossil remains indicate that this giant shark reached a length of more than 16 metres (52 ft) and also affirm that it had a cosmopolitan distribution. Scientists suggest that in life it looked like a stockier version of the great white shark, Carcharodon carcharias. -
Natural History - Fossil Rastellum Bivalve
Jurassic Period, circa 155 million years B.P.Sold for (Inc. bp): £7
A Rastellum carinatum fossil bivalve. 121 grams, 66 mm
From a Cambridgeshire, UK, collection. Property of a Cambridgeshire, UK, gentleman.
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. -
