Eocene Period, 56-33 million years BP.

From a historic ‘Victorian Museum’ collection; from the stock of Gregory, Bottley & Lloyd (1981-2014); formerly with Gregory, Bottley & Co. (1932-1981) and previously with J. R. Gregory & Co. (1898-1932); originally in the collection of the famous James Reynolds Gregory (1858-1898"). This item is part of a historic collection of fossils and minerals which has recently been reviewed by leading geological expert, Dr. Ronald Bonewitz. James Reynolds Gregory (1832-1899) was one of the principle London mineral and fossil dealers during the second half of the 19th century. The company he founded was one of the longest surviving geological suppliers in the world, second only to Kranz of Germany. In 1858 James Gregory established his business selling polished stones, minerals and fossils from premises in King William Street. A few years later he moved to premises in Golden Square, Soho. He won prize medals at exhibitions in Paris (1867), Sydney (1879) and London (1862 and 1883"). He also formed a superb collection of meteorites, which was later sold by his sons to the Natural History Museum, London. On the death of his father in 1899 Albert Gregory took over the business, dealing from premises in Kensington, then 30 Old Church Street in Chelsea. He eventually sold the company in 1932 to Percy Bottley, and after his death in 1982 the premises were sold. The company was then acquired by Brian Lloyd who had started the Natural History sales at Sotheby's before dealing from his own premises in Pall Mall. Gregory, Bottley & Lloyd, as it became known, traded from Ricket Street and later Seagrave Road in Fulham. In 2008 the business and all of the stock and Victorian cabinets were moved out of London to Walmer in Kent. On the eventual retirement of Brian and Mary Lloyd in 2014, with none of their family interested in taking over the business, the stock was sold and is now dispersed.

Eocene Period, 50-55 million years BP - Miocene Period, 23-5.3 million years BP. A group of two large fossil shark teeth comprising: one from Cosmopolitodus (Carcharodon) hastalis the extinct Giant White shark; one from Otodus obliquus from Morocco. 77 grams total, 60-81mm (2 1/4 - 3 1/4"). From the collection of the palaeontologist R. Gledhill; collected between 1930 and 1960. Cosmopolitodus (Carcharodon) hastalis is the largest of the Cosmopolitodus/Carcharodon lineage. The shark appeared in the Miocene Period and became extinct in the mid Pliocene.Cosmopolitodus hastalis have non-serrated teeth. The Otodus obliquus was the king of the early Eoceneand large examples of its teeth are not easily located in the phosphate pits in Atlas Mountains of Morocco. [2, No Reserve] Fine condition.

Eocene Period, 58-36 million years BP. A fossil fish Diplomystus from the Green River Formation, Lincoln County, Wyoming. 449 grams, 22cm (8 3/4"). 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.
