This comic explores the seeming paradox that certain extinct prehistoric species which are popularly thought of as being "dinosaurs" are, from a strict taxonomic viewpoint, not. It also takes into account the fact that all bird species are descended from dinosaurs and thus - again, from a strict taxonomic viewpoint - are themselves dinosaurs as well.

I don't think that's a stork. My guess would be that it's a heron. The bird in the lower right also looks like some sort of shorebird, but I've got no clue. 99.26.146.61 (talk) 19:45, 6 February 2026 (UTC) (please sign your comments with ~~~~)

I feel like this comic should be in the explanation https://xkcd.com/1211/ 2600:4041:2E5:B900:66D3:74AD:D92D:356B 20:36, 6 February 2026 (UTC)


Could it have a brief layman's explanation of how/why the top right *aren't* dinosaurs? Y'know beyond just "well, technically..." 91.84.189.119 06:52, 7 February 2026 (UTC)

They are not dinosaurs because dinosaurs are only a subgroup of prehistoric animals living on land. Others are flying or underwater reptiles (don’t know the real names of those), or just plain reptiles who have existed (as a group) for far longer. Dinos are technically named „land reptiles“, but are not reptiles. It’s a bit confusing and this is where my half knowledge ends
