Missouri Meteorites

Twenty-three meteorites have been found in Missouri.  The first, Little Piney, was a fall from 1839; the most recent, Conception Junction, was found in 2006.  Eight have been iron meteorites, eleven stony meteorites, three (Conception Junction, Milton, and Mincy) stony-irons.  Seven are falls - they were found shortly after they fell.  The other 15, including all the irons, are finds - they fell at an unknown time and were found later.  The Warrenton meteorite is an unusual type, a CO chondrite, and Milton is a unique pallasite.  The following information was taken mainly from the Catalogue of Meteorites (2000) edited by Monica Grady and published by The Natural History Museum of London and the Meteoritical Bulletin Database of the Meteoritical Society.
