The Saccorhytus looks somewhat like a spikey jelly bean with pursed lips and is described by the University of Bristol as "resembling an angry Minion."
What can we learn from this prehistoric organism with no anus?

They come to the conclusion in the article that it could not possibly be a common ancestor with humans, but I don't know how they could necessarily come to that conclusion. Billions of years are a long, long time.
Not gonna pretend it looks like something that would be a common ancestor with us intuitively, but when you get that far back I don't know...
