This fascinating small piece displays crust on the outer leading edge and evidence of crust and slight lipping on its two flat sides. It appears to be a single complete individual, albeit a small and very interesting one. From Wikipedia... Aguas Zarcas is a carbonaceous (CM2) meteorite that fell in Costa Rica April 23, 2019. One 280g piece struck a dog house, and another 1152g piece left a hole the size of a grapefruit in the roof of a nearby house. From the Meteoritical Bulletin (MB108): At 21:07 local time on 23 April 2019, a meteorite fall was reported in Aguas Zarcas, San Carlos county, Alajuela province, Costa Rica. The fireball traveled WNW to ESE and was caught on cameras of the National Seismological Network (RSN) at the summit of Poás and Turrialba volcanoes, and from the Volcanological and Seismological Observatory of Costa Rica (OVSICORI). Sightings were reported from Quepos (Central Pacific) in the south and north to La Palmera in San Carlos. Many stones were collected during the first five days after the fall. On the sixth day, rain fell across Costa Rica but thanks to the quick action of local villagers, we now have clear visual evidence of how a single rain event can dramatically affect the fusion crust of newly fallen meteorites. Although the Aguas Zarcas meteorite resembles the Murchison meteorite, which fell in Australia in 1969, it is actually quite distinct. This is the first time since 1969 that a large amount of Murchison-like material has been available for study and collection. Murchison is one of the most-studied meteorites in history, so this new fall is of particular interest to scientists and collectors alike, making it highly sought after. The Aguas Zarcas meteorite fall produced small, fusion-crusted stones, most of which were unbroken—a rare occurrence due to the intense forces meteorites typically endure when entering Earth's atmosphere. The piece in this lot is a very good example of one of these small pieces. -------- This item comes with a collection card in a foam-lined plastic display box, measuring approximately 58x38mm.
