Hello Bert and Thomas. I have never heard of chert before, so I have learned something new today (again), thanks to this forum. Thomas, I have been looking at your idents, but to be honest, I have no idea what I am looking at. I really am a novice in this field. I hope you'll get some answers. (if ...

Hello Bram. Thanks for your info about flint. Your remark that it can have different kind of shapes, sometimes boney like, confirmes to me that my rock must be flint, weathered by erosion. I also googled obsedian (as Thomas suggested it could be) wich is very nice looking. But I don,t think thats ...

The second picture looks like the section of a rugose coral to me.

Thanks paleobeer.
I have been googling rugose coral when I read your answer, and seen several pictures. Looking at them I think you must be right. Its nice to know.
Any ideas on the other rocks?
