Fossil Megalodon Giant Shark Tooth
Pliocene Epoch, circa 5.6 million years B.P.Sold for (Inc. bp): £234
A Carcharocles megalodon shark tooth, with serrations and polished tooth enamel. 155 grams, 10.2 cm
From a Cambridgeshire, 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. -
Fossil Knightia Fish in Matrix
Eocene Period, circa 58-36 million years B.P.Sold for (Inc. bp): £91
A Knightia alta fish on a rectangular limestone matrix. 589 grams, 17.8 cm
From a Cambridgeshire, UK, collection.
In southwest Wyoming (and parts of Colorado and Utah) in the Green River Formation are found some of the world's most outstanding specimens of fossil fish. The Green River system was composed of three lakes: Lake Ulinta, Lake Gosiute and Fossil Lake. These Eocene lakes lay in a series of intermountain basins formed by geological events that uplifted the Rocky Mountains during the early Tertiary time. The climate was much different from the desert-like climate of this area today. Both the fauna (crocodiles, alligators, boa constrictors and some subtropical fish families) and the flora (such as large palm trees) indicate a climate much like that found along the Gulf Coast today. Large amounts of ash found in the sediments indicate that volcanoes were particularly active at this time. -
