[meteorite-list] Uruaçu shield shape.

[Gabriel Gonçalves]

Hello list,


I'm a meteorite collector from Brazil and I've already had oportunity to see many fragments from the Uruaçu fall.
Talking, this week, with a friend that also have some big Uruaçus, we realize that many of the bigger fragments (more than 1 kg) usually have a shield shape, more usually than other iron meteorites.
I was thinking to myself if there is a specific reason for this or if it's only a coincidence.
Does anybody know why this could happen?

Regards,
Gabriel.
