In this paper we investigate the attenuation of sound waves originating from a ringing mobile phone, as they travel outwards from the stomach of a Spinosaurus, in order to determine whether they could act as a warning of the approaching dinosaur. Calculating the intensity lost crossing between the various media in the dinosaur's body, as well as air outside of the dinosaur, we determined this would not be possible. We calculated that the intensity of the phone ringing would be -19.6 dB when it reached their ears, which puts it just below the range of human hearing.
