Very Large Megalodon Extinct Giant Shark's Fossil Tooth
Pliocene Epoch, circa 5.6 million years B.P.Estimate: £200 - 300 (+bp*)
Opening Bid: £100
A Carcharocles megalodon shark tooth, with serrations and polished tooth enamel. 351 grams, 14.5 cm
From a Lincolnshire, UK, collection.
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. -
Sikhote Alin Meteorite
Fell 12th February 1947 A.D.Estimate: £40 - 60 (+bp*)
Opening Bid: £5
A coarse octahedrite class IIB iron meteorite; cleaned. 17.86 grams, 26 mm
From a Lincolnshire, UK, collection.
Sikhote-Alin is an iron meteorite that fell on February, 13, 1947 on the Sikhote-Alin Mountains in eastern Siberia. Though large iron meteorite falls had been witnessed previously and fragments recovered, never before in recorded history had a fall of this magnitude been observed. An estimated 70 tonnes of material survived the fiery passage through the atmosphere and reached the Earth. The strewn field for this meteorite covered an elliptical area of about 1.3 km2 (0.50 sq mi). Some of the fragments made impact craters, the largest of which was about 26 m (85 ft) across and 6 m (20 ft) deep. Fragments of the meteorite were also driven into the surrounding trees. The Soviet Union issued a stamp for the 10th anniversary of the Sikhote-Alin meteorite shower and this reproduces a painting by P. J. Medvedev, a Soviet artist who witnessed the fall: he was sitting in his window starting a sketch when the fireball appeared, so he immediately began drawing what he saw. -
