Fossil ordovician chondrites – a review

The largest group of fossil meteorites are L type chondrites, found in the Middle Ordovician limestones in Sweden. Until now, 101 specimes were discovered. Probably, they come from collisions in the asteroid belt. They are completely altered, except the chromite grains.
