We also need to bow our heads for a moment of silence, for the late great Thag Simmons.

A lot of people here have been giving you tips or criticism, but I say just keep doing your thing man. This series is great and I appreciate your direct approach to scientific descriptions of these amazing animals. I really like the intros you do as well

Thagomizer is a fine name. It is whimsical and witty, and a clever incorporation of popular culture into the scientific argot rather than a scientific term becoming popular.

I think the term Thagomizer is fine considering its pretty specific to only the groups of dinosaurs that had bony-tail weapons (which aren't many) and it describes the structure apart from say "spikes" on the body, like on Kentrosaurus. Thagomizer, works. Just like how we already call head spikes "horns" and non-spiked structures antlers or chests, I think its fair to call tail-spikes and clubs its own term.

Just watched your Allosaurus profile &, subscribed. Now this, what a doozy to watch in bed before sleep. Keep the great work up.

i can only repeat myself:
stegosaurus best saurus.

I really love Stegosaurus so much as a natural dinosaur and a very magnificent animal but I don’t understand why pop culture viewed it negatively because of the small brain.

Honestly just commenting to help engagement, this is a great video.

I watched  a  dinosaur  documentary  along  time ago   and  someone  thought  that  the  plates  on the  back  of  the  Stagosaurus could  move. 0:44

Top documentation.

Love this - please do an update featuring Apex

As a scientist, I will go with spikes haha. Just because there are too many terms and names coming out all the time and makes it rather harder to keep up with it. And ''thagomizer'' sounds rather ostentatious to me. However, this is only my opinion!
Nevertheless, I absolutely love your videos! Extremely educational, to the point, no annoying snippets from some dumb television series whatever they call them (and this I appreciate greatly!), great structure, well done research, splendid delivery!
I often rewatch your videos! I am looking forward to more content! Thank you, Andrew! Greatings from Down Under.

Very well done on Stegosaurus. You show a lot of potential, as does the channel. You should expand to do all prehistoric animals, not just dinosaurs

An excellent video.
I hope that one day a dwarf Stegosaurus, say three metres long, will be found with the thagomizer spikes half the length, when compared to the body and back plates twice the size, when compared to the body.

13:51 Thanks a lot man now I’m having to try to puzzle out in my brain how they did it. 😔 this thought will never leave me. I’ve been cursed.

Thank you this is a very well made and informative video.

Mosasaur profile would be nice please.

Thanks a lot for creating & sharing this wonderful video about an animal I always loved! BTW around 10:20 you noted that the presence on Keratin on Stegosaurus' plates would have prevented them from displaying a blushing in case of an increased blood flow into these. Not necessarily. Keratin can be also transparent - just think of our fingernails and what a nice colorful display they can present if we aren't careful whilst working with a hammer :-)

Like yeah you could call it spikes or you could call it a thagomizer because its awesome

Got to say Allosaurus sounds interesting...
