Paleontology nerd here. There isn’t an official term for the tail spikes, but thagomizer is pretty much an unoffcial official term.
I mean… if you don’t have an official term for it, but basically everyone in your field calls it a thagomizer, does that not make thagomizer the official term? If not, what makes a term “official”?
Well, whats the official term? If its just tail spikes I will be very disappointed
I just got the notification for this, sorry. There isn’t a real official term other than tail spikes, but iirc thagomizer has been used in literature, such as this paper describing a new specimen of a stegosaur from Portugal and its impacts on the taxonomy of stegosaurs
For anyone who was also wondering how accurate this is. Pretty accurate.
