April 11, 1925: The Bleckenstad Pseudometeorite

 

1925 The Bleckenstad Pseudometeorite: A ball of limestone was seen to fall to the ground near Bleckenstad, Sweden, and broke apart on impact. A geologist named Dr Assar Hadding (1886 - 1962), of Lund University, identified marine shells and a trilobite-like animal within the mysterious object, which he reported in 1939. Or, so it is said.
I believe the original source of this unlikely 'fact', which pops up time and again on the Internet, might be John Mitchell and Robert Rickard, Phenomena: A Book of Wonders p.17.
