Recent edit to Prehistoric Ireland
Hello, and welcome to Wikipedia. I noticed that you made a change to an article, Prehistoric Ireland, but you didn't provide a reliable source. It's been removed for now, but if you'd like to include a citation and re-add it, please do so! Remember that it is not acceptable to change the text attributed to a source without also changing the source unless the source has been updated since it was added to Wikipedia. If you need guidance on referencing, please see the referencing for beginners tutorial, or if you think I made a mistake, you can leave me a message on my talk page. Thank you!
