Eocene Period, 56-36 million years BP. A Knightia alta fossil fish on a matrix from Wyoming (Green River Formation), USA. 232 grams, 14.5cm (5 3/4"). From an old private collection, Lincoln, UK 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.

. A 500 carat group of tumble-polished tourmaline pieces, principally of green but also with some blue and red, from Brazil. See Bonewitz, Dr. Ronald Louis, Rocks & Minerals, 2008 p.288-289. 108 grams, 7mm average (1/4"). 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. The firm Gregory, Bottley and Lloyd (Gregory's), was acquired by TimeLine Auctions in 2016. London-born James Reynolds Gregory (1832-1899) founded the company, which is the second longest-running gem and fossil dealership in the world. James was educated at Archbishop Tennison's School, and afterward found employment in a jewellery company on Regent Street. In 1858 he established his own business in King William Street. A few years later he moved to ‘very extensive premises’ in Golden Square, Covent Garden. He was one of the best known dealers in London, exhibiting at major commercial shows throughout the world and winning awards for excellence in Paris in 1867 Sydney in 1879 and London in 1862 1883 and 1884. James primarily bought his stock at auction, from collectors and other dealers, and supplied many major collectors and scientists of his day. He built superb personal collections, a selection going to the British Museum. He wrote many papers and was a member of several learned societies including the Society of Arts. The business became known as J.R. Gregory & Company in 1896 still under James' management with the assistance of his son Albert Gregory (b.1864"). When James died three years later, the business passed to Albert. At the end of the 19th century most London dealers had folded or retired, many selling out to J.R. Gregory & Co. Albert continued by acquiring Russell and Shaw (Est. 1848) in 1925 and Francis H. Butler (Est. 1884) in 1927. Percy Bottley (1904-1980) took over the company in 1931 renaming it Gregory, Bottley & Company with respect to his predecessors. Percy’s company survived the 2nd World War by buying out all of its competitors, including the supplier to Pitt-Rivers, Samuel Henson (Est. 1840) and G.H. Richards (Est. 1897) in 1936. Percy also added many important collections to his stock including those of Rev. F. Holmes in 1940 and the Graves collection in 1943. Following Percy's death in 1981 the business was sold to Brian Lloyd, whereupon it became Gregory, Bottley & Lloyd. Brian had been Sotheby’s main Natural History expert in the 1960s and 1970s, and subsequently traded from Pall Mall. The business continued to thrive, and Brian purchased the Joseph Neeld (1789-1856) collection in 1974 and the historic gold collection of H.S. Gordon, first exhibited at the Empire Exhibition, South Africa in 1936. Brian moved the business to 12-13 Rickett Street in 1982 and to 13 Seagrave Road in 1993. He carried on the company's specialization in historic collections, most recently acquiring that of Robert Ferguson (1767-1840) in 2000. The business moved to Walmer in Kent in 2008 and was acquired by TimeLine in April 2016.

. A museum-quality reproduction of a Paleotherium from the Eocene Age (50 million years) found in Messel, Germany. 4.3 kg, 51 x 37cm (20 x 14 1/2"). This fossil is the ancestor of all horses. This fossil reproduction is an exact copy, cast directly from the actual fossil itself. Not all the ungulates of the Eocene and Oligocene epochs were directly ancestral to modern horses. However, a good example is Paleotherium, which, even though it was related to genuine prehistoric horses like Hyracotherium (once known as Eohippus), had some distinctly tapir-like characteristics, possibly including a short, prehensile trunk on the end of its snout. Most species of Paleotherium seem to have been fairly small. Very fine condition.
Cretaceous Period, 145-65 million years BP. A group of fossil Pterosaur Siroccopteryx moroccensis teeth from south of Taouz, Morocco. 13 grams total, 10-30mm (1/2 - 1 1/4"). From the collection of the paleontologist R Gledhill; collected between 1930 and 1960. [15 No Reserve] Fine condition.
Carboniferous Period, 345-280 million years BP. A mosaic of fossil white Pecopteris sp. fern specimens from St.Clair, Pennsylvania, USA. 340 grams, 16.5cm (6 1/2"). From an old private collection, Lincoln, UK These fern fossils are very common from coal mining areas around the world. However it is the unique state of preservation of the white on the black shale that gives the St.Clair ferns their beauty and rarity. [No Reserve] Fine condition.

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.

. A group of one of the most interesting Chondrites found in northwest Africa; a much studied meteorite, classified variously as L4 to L6 with some examples showing brecciation and higher metal content than others; this example seems to be an L4/5 and shows some regmaglypting and primary fusion crust. Cf. Meteoritical Bulletin #90 classified as NWA 869 an L4-6 fragmental breccia with a Shock Rating of S3 and a Weathering Level of W1. 9.66 grams, 9-16mm (1/4 - 3/4"). Found near Tindouf, Algeria, North West Africa; from the historic ‘Victorian Museum’ collection and later of Gregory, Bottley & Lloyd (Gregory's); formerly Gregory, Bottley & Co. (1932-1981) and previously J. R. Gregory & Co. (1898-1932); originally 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. The firm Gregory, Bottley and Lloyd (Gregory's), was acquired by TimeLine Auctions in 2016. London-born James Reynolds Gregory (1832-1899) founded the company, which is the second longest-running gem and fossil dealership in the world. James was educated at Archbishop Tennison's School, and afterward found employment in a jewellery company on Regent Street. In 1858 he established his own business in King William Street. A few years later he moved to ‘very extensive premises’ in Golden Square, Covent Garden. He was one of the best known dealers in London, exhibiting at major commercial shows throughout the world and winning awards for excellence in Paris in 1867 Sydney in 1879 and London in 1862 1883 and 1884. James primarily bought his stock at auction, from collectors and other dealers, and supplied many major collectors and scientists of his day. He built superb personal collections, a selection going to the British Museum. He wrote many papers and was a member of several learned societies including the Society of Arts. The business became known as J.R. Gregory & Company in 1896 still under James' management with the assistance of his son Albert Gregory (b.1864"). When James died three years later, the business passed to Albert. At the end of the 19th century most London dealers had folded or retired, many selling out to J.R. Gregory & Co. Albert continued by acquiring Russell and Shaw (Est. 1848) in 1925 and Francis H. Butler (Est. 1884) in 1927. Percy Bottley (1904-1980) took over the company in 1931 renaming it Gregory, Bottley & Company with respect to his predecessors. Percy’s company survived the 2nd World War by buying out all of its competitors, including the supplier to Pitt-Rivers, Samuel Henson (Est. 1840) and G.H. Richards (Est. 1897) in 1936. Percy also added many important collections to his stock including those of Rev. F. Holmes in 1940 and the Graves collection in 1943. Following Percy's death in 1981 the business was sold to Brian Lloyd, whereupon it became Gregory, Bottley & Lloyd. Brian had been Sotheby’s main Natural History expert in the 1960s and 1970s, and subsequently traded from Pall Mall. The business continued to thrive, and Brian purchased the Joseph Neeld (1789-1856) collection in 1974 and the historic gold collection of H.S. Gordon, first exhibited at the Empire Exhibition, South Africa in 1936. Brian moved the business to 12-13 Rickett Street in 1982 and to 13 Seagrave Road in 1993. He carried on the company's specialization in historic collections, most recently acquiring that of Robert Ferguson (1767-1840) in 2000. The business moved to Walmer in Kent in 2008 and was acquired by TimeLine in April 2016.
