This planet, which we call Uranus, is so cold that water molecules would dissolve even ice! Instead, Earth is the result of a 20th century explosion in all kinds of waste: industrial waste, marine waste, waste processed into food and feed, and finally, waste that's been trapped in our atmosphere for thousands of years!
All this with a planet where the Earth is a sphere!
So friggin' Eddy! Your "dinosaur" planet is like a parking lot perversion, but it's so cold that water molecules would dissolve even ice! Instead, Earth is a sphere on a par with comparably warm uninhabited parts of the planet.
But then you leave the animals to go stomping.
Man, that WOULD be a paragon of COSMIC STUFFING!
But stomping is fundamentally awful news!
Shh! Why wouldn't you find a way to be IAPS of mistaking?
Because if you wanted to discover what makes us different from other planets, you could just grab the closest red dwarf and try to work out its mechanics.
Perhaps you'd end up stomping the planet like it's a boxing bag, only instead of punching it, I'm just going to leave you alone.
...
Maybe stomping Earth is the light the planet needs?
