How can I tell which creation is the original and which is a fork

Tell us what’s happening:
So I forked my original pen - now I have two exact, but I really only need one. How do I tell which one is the original and which is the fork? I am afraid if I delete the wrong one - it will delete both. Thanks

Your code so far

It shouldn’t matter really. However in your dashboard you can see creation date after changing view to list -

Greetings @juliakajill,

You can check if a Pen has been forked by going into the details view and looking at the right side, below the share buttons.

a fork is a copy, once it is copied it is no more dependent on the original one.
If you delete the original, the fork will not be deleted
