Fossil Megalodon Giant Shark Tooth
Pliocene Epoch, circa 5.6 million years B.P.Sold for (Inc. bp): £104
A Carcharocles megalodon shark tooth, with serrations and polished tooth enamel. 126 grams, 10 cm
Property of an Essex gallery.
Carcharodon megalodon is regarded as one of the largest and most powerful marine predators in vertebrate history and likely had a profound impact on the 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. -

Fossil Mosasaur 'Marine Dinosaur' Tooth Group
Cretaceous Period, circa 145-65 million years B.P.Sold for (Inc. bp): £65
Comprising three Mosasaur Prognathodon teeth, each showing good enamel. 60 grams total, 46-65 mm
From Ouled Abdoun Basin, Morocco, West Africa. From the private collection of Kenneth Machin (1936-2020), Buckinghamshire, UK; his collection of antiquities and natural history was formed since 1948; thence by descent.
The Mosasaur is an extinct, large marine reptile dinosaur with an elongated body, long snout and paddle-like limbs. Found worldwide, they competed with other well-known sea predators of the Late Cretaceous, such as plesiosaurs and ichthyosaurs, for food, existing primarily on a diet of ammonoids, cuttlefish and fish.
