Two egg type stones or fossils with lots of surface patterns
Two prettily patterned
Found these two rocks or fossils on a beach in Panama, Central America, within a few days of each other.
I have never seen anything similar either before or since and have been searching online for months.
They are quite light and I first thought they were fruit seeds, now I think they could be naturally formed by sea weed or a similar plant. Any ideas would be great, including what type of rock. Thanks!
