Deletion of Mesozoic mammals of Madagascar

Comment: Mesozoic mammals is a topic - it's a WP category, and also one in other publications, in general and in Madagascar specifically (eg 'Madagascar's Mesozoic Secrets' in ''Scientific American'' https://www.nature.com/scientificamerican/journal/v23/n2s/full/scientificamericandinosaurs0514-28.html, ''Mesozoic Mammals: The First Two-Thirds of Mammalian History'' https://books.google.com.au/books?id=voLf4BxSpWkC&pg=PA293&lpg=PA293&dq=Mesozoic+mammals+of+Madagascar&source=bl&ots=tHKE2bwajR&sig=QzzWSPJxulenoTDrkAkvf4ldxlU&hl=en&sa=X&ved=2ahUKEwiPj7zC8treAhUCzbwKHQJECdQ4HhDoATAFegQIBBAB#v=onepage&q=Mesozoic%20mammals%20of%20Madagascar&f=false) and university courses (eg https://www.geol.umd.edu/~tholtz/G104/lectures/104shadow.html). It therefore meets  Other publications also have articles about Mesozoic mammals in other countries/continents (eg ''Science China Press'' 'Mesozoic mammals—what do we know from China?' https://phys.org/news/2015-02-mesozoic-mammalswhat-china.html). The fact that Wikipedia does not yet have articles on Mesozoic mammals of other countries/continents is not a reason to delete this article

Comment: as per RebeccaGreen. Just because someone has not bothered to create an article yet about another notable subject does not mean an article on another  notable subject should be deleted. Who decides the order of notability and the order of article creation? If we are to go that route a lot of articles will be pulled down. There is significant and in-depth coverage from several independent and reliable sources. This article therefore satisfies the general notability guidelines and merits a stand alone article. Reading the nominator's rationale and examining the article for myself, I have so far seen no evidence that this article fails GNG or should be deleted because of  or any policy for that matter. |I don't like it or |what about X are not good reasons for delete
