Lower Cretaceous Period, 120 million years BP. A large complete fossil Vinctifer sp. fish from the Santana Formation, Ceara, Brazil. 914 grams, 41cm (16 1/4"). From an old Bristol paleontological collection; acquired 1950s-1960s. This fish was a member of the Aspidorhynchid family, a highly specialized extinct group that lived from the Middle Jurassic Period 160 million years ago to the end of the Cretaceous Period 65 million years ago. . Fine condition, repaired.

Pliocene Period, 5.2-2.5 million years BP. A mastodon fossil bone with later carving from Java. 105 grams, 10.5cm (4"). From an old Bristol paleontological collection; acquired 1950s-1960s. [No Reserve]. Fine condition.

Oligocene-Miocene Period, 38-25 million years BP. A piece of cut and polished agatised fossil coral showing internal structure and colour. 130 grams,12.8cm (5"). From Tampa Bay, Ballast Point, Florida, USA; from an old Bristol, UK, collection; acquired before 1960. [No Reserve]. Fine condition.

Eocene Period, 58-36 million years BP. A fossil Mioplosus labracoides fish from Warfield's Quarry, Kemmerer, Green River Formation, Wyoming, USA. 305 grams, 20.5cm (8"). 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.

A fine example of the ammonite Perisphinctes sp. with much of the original shell material remaining, in old white card tray with old label reading: 'AMMONITE Perisphinctes sp., Mid Jurassic Age (approx. 170 million years old), Madagascar'. 162 grams, 86mm (3 1/4"). From the historic ‘Victorian Museum’ and later collection 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 the 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.

From the collection of the palaeontologist R Gledhill collected between 1930 and 1960. The Spinosaurus was both a beachcomber type scavenger and an active hunter taking small stranded plesiosaurs, pterosaurs, turtles and large fish. [6, No Reserve]. Fine condition.

Lower Lias, Sinemurian, 200-180 million years BP. A group of Promicroceras sp. ammonite fossils in matrix. 1.3 kg total, 63-82mm (2 1/2 - 3 1/4"). Private collection, Cambridgeshire, UK; acquired prior to 2000; from Charmouth, Dorset, UK. [10, No Reserve]. Very fine condition.

Oligocene Period, 45 million years BP. A group of six pieces of Baltic amber each containing flies together with other inclusions. 2.46 grams total, 7-12mm (1/2 - 1"). From the collection of the palaeontologist R Gledhill collected between 1930 and 1960. [6, 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. 745 grams, 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. . Fine condition.

Cretaceous Period, 145-65 million years BP. A group of twenty-two Perisphinctids of various sizes and an echinoderm. 522 grams total, 22-69mm (1 - 2 3/4"). Private collection, Cambridgeshire, UK; acquired prior to 2000; from Madagascar. [23, No Reserve]. Fine condition.
