🦖 What kind of sound is the dinosaur really?
🦖 What kind of sound is the real dinosaur?
Probably not a roar like we've heard in movies.
If you think of the sound of dinosaurs,
The first image that appears in the head is usually
A thunderous roar, T-rex in the movie.
But the scientific truth is...
Most of those sounds were made.
And maybe not even close to the truth.
🎬 Where did the sound in the movie come from?
Dinosaur sounds in the movie
Often created from mixing the sounds of
• Lion
• Tiger
• Elephant
• Crocodile
To look scary and erotic.
Not for scientific accuracy.
Simply put,
The movie needs "excitement."
Not "the truth."
🔬 The problem is... fossils don't keep sound.
We never found out.
The vocal cords of dinosaurs in fossils.
Because of soft tissue.
Can't be turned to stone.
So scientists have to
Relying on comparisons to current animals.
Especially.
• Birds (closest relatives)
• Crocodiles (nearby phylogenetic relatives)
🐊 The sound may resemble a crocodile more than a lion.
Crocodiles don't roar like mammals.
But will.
• Low noise
• Vibration
• Use throat air pressure
Sometimes you "feel" the sound.
Before I even heard it.
Scientists believe
Large dinosaur
Could sound this way.
More than the kind of grunts in the movie.
🐦 What about the bird sound?
Many kinds of birds.
Didn't cry loudly.
But use sound to
• Communicate
• Alarm
• Call a couple
• Call the baby.
If a bird is a living dinosaur,
The Sound of an Ancient Dinosaur
Could be.
• Low voice
• The hum.
• Inflatable sound
• Or trembling in the throat
More than "yelling at each other."
🌍 The dinosaur-era world may be quieter than thought.
Imagine
Instead of a world full of roars,
The dinosaur age world may have
• Sound of wind
• Footsteps
• Low vibration
• Intermittent warning sounds
Quiet... but pressure
🧠 Why don't dinosaurs have to roar?
In nature.
Loud is not always an advantage.
A good hunter.
No need to declare yourself.
Sound may make
• The victim knows
• Competitors know the position
Silent communication
Probably safer.
✨ lessons from voices we've never heard.
The Sound of Dinosaurs
Teach us that
Something that looks scary in the movie.
Probably not a fact of nature.
And sometimes
Silence.
May be more scary than roaring
