hi i have found these flint type stone's on my local beach.. they all have raised stipe like markings.
and i wondered if the could be trilobites.this was a local beach in margate,kent. england.
could u please help me identify them.. thankyou,
No, they're not trilobites, though that's a reasonable first thought.
They are nice examples of 'banded flint'.
Have a look at these references:
Also, the flints you'll find on the beaches of southern England originated in Cretaceous chalk strata; and the trilobites had died out by the end of the Permian - at least 100million years beforehand.
