Welcome!
Hello, Howard ZHY, and welcome to Wikipedia! Thank you for your contributions. I hope you like the place and decide to stay. Unfortunately, one or more of your recent edits did not conform to Wikipedia's verifiability policy, and may have been removed. Wikipedia articles should refer only to facts and interpretations that have been stated in print or on reputable websites or in other media. Always remember to provide a reliable source for quotations and for any material that is likely to be challenged, or it may be removed. Wikipedia also has a related policy against including original research in articles.

If you are stuck and looking for help, please see the guide for citing sources or come to the new contributors' help page, where experienced Wikipedians can answer any queries you have! Here are a few other good links for newcomers:

I hope you enjoy editing here and being a Wikipedian! Please sign your name on talk pages using four tildes ( ~ ); this will automatically produce your name and the date. If you need help, check out Questions, ask me on my talk page, or. Again, welcome. Loopy30 (talk) 12:09, 26 February 2019 (UTC)

Fossil ranges
I have reverted your edits to several articles because you changed the dates in the fossil ranges for those articles without providing any explanation or citing any reliable sources. It is helpful to other editors to provide some sort of explanation of what you did in the edit summary, especially when changing things in in infoboxes. Please also note that since I have reverted your changes, if you want to restore your edits, you should either open a discussion of the proposed change on the article's talk page, or at least provide a citation to a reliable source for the date range you prefer. If, however, reliable sources do not agree on a specific date raange, it would be best to discuss any changes on the talk page before making them. - Donald Albury 12:58, 26 February 2019 (UTC)
