MARTIAN STONE - NWA 14713 Lherzolitic shergottite 127 g “This 127-gram fragment of the NWA 14713 meteorite displays a green-black mottled exterior. The rock is a martian shergottite (a basalt) composed mainly of coarse grains of pyroxene as well as calcium-plagioclase glass. This glass, called maskelynite, formed from crystalline plagioclase when the specimen was blasted off the surface of Mars by an energetic collision. There are currently less than 350 known martian meteorites...

NWA 12759 Stone, Chondrite - L5 18.3 KG “This specimen of the NWA 12759 L5 chondrite has a smooth posterior fusion crust where meteoritic melt pooled as the rock descended through the atmosphere and was heated by friction with molecules of air. The meteorite is from the L-chondrite asteroid that was destroyed by an energetic collision 470 million years ago.” Dr Alan E. Rubin, PhD Department of Earth, Planetary, and Space Sciences, UCLA Detached from its parent body by a mighty impact, this large, oriented meteorite travelled over a hundred million miles through space before falling to Earth in the North African desert. Beautiful regmaglypts radiate from the apex of its cone shaped nose. These elongated dimples formed when streaks of superheated molten rock streamed off the meteor’s surface as it blazed through the atmosphere. The entire piece is coated in a glossy, umber-coloured fusion crust and close examination reveals remnants of encrusted, orange dirt. Whilst most meteors tumble as they travel through the Earth’s atmosphere, oriented meteorites...

A large red iridescent ammonite fossil dating from the late cretaceous period (100.5 – 66 million years ago). This huge plancenticeras ammonite is approximately 16 inches tall and has an iridescent lustre that showcases a vibrant red hue. Once a living creature, this ammonite has developed its red iridescent lustre over millions of years of compression, transforming into a striking gemstone. A rare find. Provenance: From the fascinating collection of Gordon Walkden (1944-2022), emeritus Professor of Geology at Aberdeen University. Affectionally known as Aberdeen’s answer to Indiana Jones, Walkden contributed enormously to research through his papers and talks on British marbles, minerals and fossils...
