The current explanation for Gorosaurus's name looks like someone just typed in "goro" into google translate, using the automatic WHATEVER to get "ごろ," which will come out as "around" which that someone assumed meant "approximate."

BUT if you actually take the kanji from the "goro" part of his Japanese name, ゴロ, it means something different. You'll actually get "grounder" just typing that in but ignore that for a moment. "ゴロ" comes from the word for the sound of thunder in Japanese, an onomatopoeia which are usually written twice. So it'd be "gorogoro" which would be translated as "rumble" or "rumbling" in English. You'll still get "grounder grounder" typing that in, but to confirm this just give it the slightest bit of context, "ゴロゴロの," and it'll come out as "of rumbling." I'm guessing his roar is supposed to sound like the rumbling of thunder, lol.

I know this only because I'm a fan of One Piece, and in that series is a fruit called the Rumble Rumble Fruit, in Japanese the Goro Goro no Mi, which gives the person who eats it the powers of lightning. http://onepiece.wikia.com/wiki/Goro_Goro_no_Mi wouldn't look good as a reference but at least I can confirm this explanation.
