Multiple Knightia Fossil Fish in Matrix
EOCENE PERIOD, CIRCA 58-36 MILLION YEARS B.P.
4 3/4 in. (135 grams, 12.2 cm).
A rounded matrix with multiple Knightia alta specimens. [No Reserve]
ProvenanceFrom Wyoming (Green River Formation), USA.
From a Lincolnshire, 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.

Madagascan Giant Monkey Ladder Sea Bean
Sold for (Inc. bp): £130
A very large Entada gigas or sea bean pod, containing nine separate sea bean segments; rare. 419 grams, 79 cm
Fine condition. Rare.
From Madagascar. Ex private Shropshire, UK collection.
Entada gigas, the ‘sea bean’ or ‘monkey ladder vine’ is a flowering liana in the Fabaceae pea family. The plant has the longest seed pods in the family, as well as the largest seeds, which can float for miles along sea currents, being washed up on beaches around the world. The seed pod segments snap off, dropping into the river below. The pod segment will quickly rot, revealing the seed or ‘sea bean’ inside. The seed contains a sealed pocket of air, which enables it to float. It can survive for up to two years at sea, and actually requires prolonged exposure to water in order to germinate. Some of these seeds will find their way into the major sea currents, such as the Gulf Stream, and end up washed up on coasts around the world. -
