The same image of Meat-Eater from King Kong (1933).
These are RKO Radio Pictures sound effects. They were created by Murray Spivack, and they made their debut in the 1933 adventure monster film King Kong. Sadly, not much is known about how they created the Meat-Eater's noises aside from that they used various recordings of a cougar.
Dinosaur Ringtones (Two slightly lower pitched and lower quality variants are used in the app. One as the sound for the Allosaurus, and another one with a reverb effect added as the sounds for the Atrociraptor and the Jaxartosaurus.)
