Hello, I'm Trains2050. I noticed that you made a change to an article, Ichthyosaurus, but you didn't provide a source. I’ve removed it for now, but if you’d like to include a citation to a reliable source and re-add it, please do so! If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thanks. Trains2050 (talk) 18:25, 10 June 2020 (UTC)

Please do not add or change content, as you did at Paleontology in the United States, without citing a reliable source. Please review the guidelines at Citing sources and take this opportunity to add references to the article. Thank you. Jurassic Classic 767 (talk | contribs) 19:28, 10 June 2020 (UTC)
