The night before the demo presentation, I created a good pterodactyl scream by taking a recording of dolphins, reversing it, and dropping the frequency. Sounds strange, but I didn't have much time, and the effect was surprisingly good. A woman from marketing was trying the ride and raved that we got the pterodactyl scream just right.
Perhaps Toho would have added it if the recording & reproduction systems of the time could have produced it, I don't know.
Wikipedia says it was created via "...rubbing a resin coated glove along the string of a contrabass and then slowing down the playback" http://en.wikipedia.org/wiki/Godzilla

Think about what good foley means to you. The arrival or departure of the TARDIS. Godzilla's roar. The sweepy red light on KITT. The "pew pew" of a laser gun that shouldn't really make any noise at all. The incongruous farty buzzing sound of a GAU-8 taking apart a tank. The crackle and hum of a light saber in motion. The "errr aka-chicka aka-chicka tullet-peppa tullet-peppa" of Ripley entering the Nostromo's computer core. The signature sound of a modem handshake. The ringtone of the very first mobile phone you ever owned.
It's just as important as the visual portion of a story, but gets much less respect.
