Rocks thought to come from space

[bary11]

Hello,
I don't know much about geology and need help for identification of these rocks.
A friend of mine found these objects in a remote location in Mauritania (a country where Professor Théodore Monod spent his life looking for a mysterious meteorite).
Local people pretend it came form space
Does anyone have an idea about it? Thank you in advance

All those samples are terrestrial. Take them to any geologist for confirmation.
