Hehe, cool. I actually visited Thorsberg quarry last week on an excursion in my sedimentology class. Didnt find any meteorites however. But a lot of trilobites and orthoceratites.
(Im a student of geology at a basic level at the University in Lund.)
I found that website a while back but your brought this back into my memory Callan.
I wonder what are the chances to find fossil meteorites in other limestone formations of younger age.
I don't know... It had never even occurred to me to wonder if there were meteorites as inclusions in sedimentary formations. I was surprised and delighted when I was alerted to this page earlier today.
I think they would be especially easy to find in limestones and evaporites because theye are usually void of large siliciclastic or even metallic clasts. Also the color different would make them easy to spot.
What got me thinking is that I will be mapping some 8km2 of Jurassic limestones next month and that perhaps I should also have an eye for weird looking rocks from outer space. Hehe.. :D
