I can't be happy until we de-extinct a giant bird giraffe so I can ride it into battle against my neighbors.
Why do you people keep laboring under the delusion that quetzalcoatlus could be ridden? Look buddy, unless you manage to find a tiny one thats been bullied and go on an adventure that teaches you both about friendship this interaction can only end with you getting purposefully dropped from great height like a tortoise.
And it might even still happen once it gets over its self esteem issues. It doesnt need you.
