You should tell us what extinct species we can bring back to life

This was my childhood. I remember being addicted to this dude as a kid. Good to see him still going on and not being caught up in some unnecessary drama. Thanks for being part of my childhood

Patogtitan mayorum and argentinosaurus who would win in a fight

[patrickcollins]

Do pterosaurs or sarcosuchus the super crocodile

Thank you for making a different video on a new topic Mr. Demaio!

That's EZ Mr.D, it's Argentinosaurus is the biggest dinosaur that ever live. A bull Argentiosaurus weighs as much as 20 bull elephants
