ynot Posted September 3, 2018 Share Posted September 3, 2018 Welcome to TFF! Can We see other sides and ends - without the shadow? Darwin said: " Man sprang from monkeys."

Tidgy's Dad Posted September 3, 2018 Share Posted September 3, 2018 Looks like chert to me, but other photos may help. Welcome to TFF from Morocco. And what's that on the right? One of those new-fangled replacements for the cigarette lighter? Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...
TqB Posted September 3, 2018 Share Posted September 3, 2018 I think it's a piece of Cretaceous flint - plenty around there in the Boulder Clay and the Chalk isn't far away. Pieces that shape often formed in burrow systems - sponge is another possibility so end views would help. Tarquin Link to comment Share on other sites More sharing options...
Ludwigia Posted September 3, 2018 Share Posted September 3, 2018 I'll go along with flint/chert. Greetings from the Lake of Constance. Roger http://www.steinkern.de/ Link to comment Share on other sites More sharing options...
