Bifacial Partial Fossil Ichthyosaur Jaw
Mesozoic-Jurassic Period, circa 250-90 million years B.P.Sold for (Inc. bp): £1,040
Showing multiple sharp teeth and a section of well-formed, slender jaws. 270 grams, 10.6 cm
Discovered at Lyme Regis, UK, during the time of Mary Anning and her family. From an old English collection. Ian Wilkinson collection, Nottinghamshire, UK, formed since 1985. With an original early 19th-century handwritten identification label ‘Nose of a Saurian’, the original discovery of this fossil can be dated to the period 1800-1830.
Originally, ichthyosaur fossils were misidentified as ‘Saurian’ - being either lizards or forms of crocodile. The term 'Ichthyosaur' was first used in 1817 by the German naturalist Karl Dietrich Eberhard Konig, and he did not publish the name until 1825. By the 1830’s, the name Ichthyosaur was widely used. Having been discovered in Lyme Regis, this dates the discovery of the fossil to the ‘Golden Age’ of fossil hunting in the early 1800s (before the use of the name ‘ichthyosaur’) made especially famous by Mary Anning and her family, who collected fossils from the coast around Lyme Regis and who sold specimens, for additional income, to tourists as well as leading naturalists and fossil collectors from around the world. -
Woolly Mammoth Bone Bead Necklace String
Pleistocene Epoch, 2.6 million-11,700 years B.P.Sold for (Inc. bp): £78
Restrung, using recently polished Mammuthus primigenius spherical bone beads. 197 grams, 60 cm
London, UK, collection, 2000.
The mammoth lineage branched from the Asian elephant around 6 million years ago, and later on the Woolly Mammoth, Mammuthus primigenius, evolved in eastern Siberia. Woolly mammoths, being slightly smaller than living African elephants, were foragers and ate grass, as well as small, nutritious flowering plants that flourished in the environment where they lived. They may also have used their curved tusks to dig through snow and eat plants that other foragers were unable to reach.
