From the collection of the palaeontologist R Gledhill; collected between 1930 and 1960. [6, No Reserve] Fine condition.
Cretaceous Period, 145-65 million years BP. A large Charonosaurus sp. hadrosaur egg on matrix retaining evidence of the original leathery surface. 3.8 kg, 15.5cm (6"). Property of a Cambridgeshire gentleman since 1990; previously in a private collection formed in the 1980s. Dinosaur eggs are known from about 200 sites around the world, the majority in Asia and mostly in terrestrial (non-marine) rocks of Cretaceous Age. It may be that thick calcite eggshells evolved during the Cretaceous (145 to 65 million years ago"). Most dinosaur eggs have one of two forms of eggshell that are distinct from the shells of related modern animal groups, such as turtles or birds; however, some eggs closely resemble the type of shells seen in present day ostrich eggs. Fine condition.

Eocene Period, 56-33 million years BP. A Knightia alta fossil fish in a matrix. 441 grams, 18.2 x 11.4cm (7 1/4 x 4 1/2"). From the Pradi Collection, Boston, USA; acquired during the 1980s; from Wyoming, Green River Formation, USA. Seasonally some 58 million years ago, in the Green River region of Wyoming, torrential rains would occur in the mountains. The rain would flow down the mountain sides and then wide shallow lakes would form in the valley below. When the dry season would occur, these lakes would dry up due to evaporation (similar to certain parts of Africa today"). Millions of fish would die in this short period of time. This climatic cycle happened over a 20-thousand-year period. Layer upon layer of mud was deposited over these years entombing all these fish. At a much later date volcanic activity uplifted this area to expose all those layers of fossil fish. [No Reserve] Fine condition.

Eocene Period, 58-36 million years BP. A fossil Priscacaraliops sp. fish from the Green River Formation, Lincoln County, Wyoming, USA; mounted on a custom made back-plate. 1.06 kg, 26cm (10 1/4"). From the Pradi Collection, Boston, USA; acquired during 1980s. 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. [No Reserve] Fine condition, repaired.
Eocene Period, 56-33 million years BP. A fossil Knightia alta fish in a matrix. 262 grams, 12.7 x 9cm (5 x 3 1/2"). From an old Bristol paleontological collection; acquired 1950s-1960s; from Wyoming, Green River Formation, USA. Seasonally some 58 million years ago, in the Green River region of Wyoming, torrential rains would occur in the mountains. The rain would flow down the mountain sides and then wide shallow lakes would form in the valley below. When the dry season would occur, these lakes would dry up due to evaporation (similar to certain parts of Africa today"). Millions of fish would die in this short period of time. This climatic cycle happened over a 20-thousand-year period. Layer upon layer of mud was deposited over these years entombing all these fish. At a much later date volcanic activity uplifted this area to expose all those layers of fossil fish. [No Reserve] Fine condition.
