Natural History - Knightia Fossil Fish
Eocene Period, circa 58 million years B.P.Sold for (Inc. bp): £78
The rectangular matrix containing a Knightia alta fish. 233 grams, 14.6 cm
From Wyoming (Green River Formation), USA. Acquired during 1980s. From the Pradi Collection, Boston, U.S.A.
Seasonally some 58 million years ago, in the Green River region of Wyoming, torrential rains fell in the mountains. They flowed down the mountain sides, forming wide shallow lakes in the valley below. During the dry season, these lakes would dry up due to evaporation (as happens in certain parts of Africa today). Millions of fish died in this short period of time. This climatic cycle happened over a 20-thousand-year period. Layer upon layer of mud entombed all these fish. At a much later date, volcanic activity uplifted this area to expose the fossils. -
Natural History - Chinese Nantan Meteorite
Fell 1516 A.D., found 1958 A.D.Sold for (Inc. bp): £78
An amorphous nickel iron Nantan meteorite (1AB), cleaned. 3.58 grams, 22 mm
Found Nantan, Nandan County, Guangzi Region, China. Property of a Sussex, UK, teacher.
The Nantan meteorite fell in 1516, as recorded in ancient Chinese texts; the fall exploded during descent which resulted in a shower of many individual iron meteorites over an area some 28km x 8km in Nantan County, Guangxi, China. Classified as an iron meteorite; 111CD Course Octohedrite, the composition is approximately 92% iron, 6% nickel and contains more than ten other minerals including kamacite, taenite, dominate, plessite, schreibersite, triolite, graphite and others. In 2000, pieces of the Nantan meteorite were incorporated into an art installation for The Bull Ring Shopping Centre in Birmingham, England. Today, a plaque commemorates the occasion.
