This rather tasty, large graptolite just arrived after a surprise auction win. It's labelled Clonograptus rigidus Hall which seems reasonable though I'm always being caught out by these. The location is given as 25km north of Zagora (should be OK?) but the age is given as Floian stage when I'm pretty sure it should be Tremadocian, probably Murrayi Zone. ( @Spongy Joe - I guess you've seen a lot like this... )
