Natural History - Amber with Insect Inclusions

An amorphous fragment of nickel iron meteorite (1AB), cleaned. 4.16 grams, 28 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.

On a rectangular matrix. 292 grams, 15.7 cm



From Wyoming (Green River Formation), USA. From an old Bristol, UK, collection.

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.

Comprising complete and fragmentary belemnites and Gryphaea, devil's toenail, fossils. 587 grams total, 23-62 mm
