Nope, nope, nope!
Remember the actual question:

Many LBT characters have names based on the kind of dinosaur they are. Once however a dinosaur (who doesn't play any important role in the movie I'm talking of and is just a total background character) is named by the actual name of it's kind, just the ending "-saurus" has been left out. Which movie ist it, who says the name? And what is the name?

Neither Tickles (who's species is not absolutely sure; most likely a Megazostrodon, but that wouldn't even be a dinosaur) nor Nod are ever addressed like that (In Nod's case someone would have to call him "Nodo" to met the criterion). And as I said, this character doesn't speak a single word in is not important for the story. I hid one further hint in this message (a very subtle one though).
