Hello, I'm MichaelMaggs. I noticed that you added or changed content in an article, Blue Lias, but you didn't provide a reliable source. It's been removed and archived in the page history for now, but if you'd like to include a citation and re-add it, please do so. You can have a look at referencing for beginners. If you think I made a mistake, you can leave me a message on my talk page.   MichaelMaggs (talk) 16:00, 4 August 2021 (UTC)
