I found them at the west side of charmouth beach . I really want to know what they are. had search about rock and found them looks like agate and coral rock . But I am not sure . I had also tried to contact the charmouth heritage coast centre. But can't contact them . So, I tried to ask at here and hope someone can identify them for me . Thank you in advance . The follow are photo of those two rocks .

I agree with not fossils and a quartzite, flint, chert or agate.
