Nice specimen! Am I right when I think I'm looking at a lateral view on your photo, with the periproct to the left? If that's correct, is the round hole in the test a parasite hole or something like that?

Greetings,
Bram

The hole on the side is predation drill hole and is actually tapering inwards on the test.
