Description: For sale is an exceptionally fresh and beautiful unclassified regmaglypted specimen weighing 303.80 grams. It features a pristine frothy fusion crust with contraction cracks and numerous regmaglypts. This museum-quality find, recently discovered and unstudied, is among the top pieces available. The meteorite, along with two others, was discovered near Bassikounou, Mauritania, around January 22, 2022. A COA card is included with this meteorite. Thank you for your interest, and stay well. The meteorite exchange says: Oriented meteorites have frozen in their shape and surface the record of their fiery passage through the Earths atmosphere. All meteorites arrive on the surface of our world by the same experience, but only the rare few that are stable during flight will show the marks of ablation and accumulation. These are the oriented meteorites. Some of these marks are radial flow lines, splattered material clinging to the sides behind the forward surface, and lips and ridges of melted material that has flowed as liquid back from the front. Any type of meteorite can be an oriented one. The material is not what is important. It is the fact that only one surface remains the forward surface during the ablation part of entry flight. There are some very famous oriented stones. Martin Horejsi shared in this publication last month the Eagles Nest oriented meteorite which is a stone type. But, with large numbers of small irons currently available from falls such as Taza, and Sikhote Alin, offer us a portion of their numbers that are oriented. I have spent a good deal of my time at gem shows hunting through trays of these for oriented specimens. Meteorites Australia says: As a meteor travels through the Earth's atmosphere, the heat generated ablates material away. If the meteor is able to achieve stable flight rather than tumbling sporadically, then the material will ablate in an even manner, creating what is known as a shield or nose-cone shape. In fact, ideas for space re-entry vehicles were designed from this natural shape, which tends to dissipate the high amounts of energy better. The leading side (front) and sides often have flow-lines on the surface, which indicates the direction the material was being ablated. The rear edges of the trailing side can create a 'roll-over' rim or 'lip' where the ablating/melting material has started to roll-over onto the back side. Sometimes, specimens will also have 'frothing' on the trailing side where the crust has literally bubbled.
