Ancient prehistoric bird sound evoking primal fear: infrasonic subterranean rumble rising into a low guttural roar like distant crocodile gurgling mixed with a hollow howler monkey call, shifting into distorted cries, then cold metallic bird clicks and whistles jumping from deep lows to piercing highs as if the creature circles the listener, ending in a trembling bass trill with rasp, croaking textures and broken breathing, sub-bass felt physically, designed to cause goosebumps and unease.

A prehistoric apex predator vocalization, Tarbosaurus. High-definition organic soundscape. Start with a dry, throaty hiss like a giant monitor lizard, transitioning into a rhythmic, guttural growl. Include the sound of "closed-mouth vocalization" – a hollow, resonating vibration similar to a large emu or a crocodilian bellow. Add wet, squelching throat textures and sharp, raspy breath exhales. No cinematic roars.
