What's wrong with bunny hands on dinosaurs? (2018)

This reminds me of one of my favorite YouTube series, Your Dinosaurs Are Wrong. They were short little videos where a guy had a toy dinosaur and he would explain why the toy was incorrect. Short, easy to understand, fun, and I learned a lot. Highly recommend to anyone of any age.

Playlist of the original videos: <https://www.youtube.com/playlist?list=PLaCDmykyjVw_B983AQ2iG...>, there's a channel now <https://www.youtube.com/@YourDinosaursAreWrong> which has newer episodes (can't vouch for, haven't seen) (playlist with old and (some of the) new: <https://www.youtube.com/playlist?list=PLnpbQOy7TfC179wPmhHZr...>)

This would make for a good topic on a short-form pop-science YouTube channel. (take your pick)

The article is interesting but it's difficult for me to really picture the implications of the article. Actually after reading it I get the feeling that what I was visualizing is entirely contrary to what they are trying to convey to me.

What exactly is "bunny hands"? I'm having difficulty picturing it.
