But I've included both the "thunder" derivation and the Gorgosaurus derivation in the article, since it seems nobody can pinpoint the name's origin.

And Lookatme, "fifth" is daigono, so it's unlikely that's the derivation of the name. Ugh finally I've been waiting to get back and talk about this. Actually what you say is true, but that is also where you are wrong; the Japanese term for Goro is also used for the numerical math in Japan and also serves as a name. The name means "fifth" or even "approximate" the name can translate as "fifth son" so anybody in Japan that as a fifth son is name Goro or Gorou (五郎)(whatever pronunciation fits) and since being that Gorosaurus was the fifth dinosaur or reptillian kaiju to appear in the Toho lineage (excluding Manda) it is more likely this is where the monster gets it's name from.
