Ok so I was watching this video:
In the comments someone writes the usual spiel about all fossils being transitional but it occured to me that if the particular animal that came to be the fossil never procreated it would therefore not be a transitional fossil. Am I getting this right or is there another reason it is still considered transitional. I suppose with something so old we could never know and it doesn't really matter all that much but at least I have an excuse to share this video.
