Hopefully, in the future, Entelodonts will be more that just a bizarro April Fools joke.
If it was possible, I'd give scientists the green light. I'd give anything to see a live T-Rex. What does it sound like? What does it use those little arms for? How fast and strong is it? We could get those answers in real-time.
But most animals during the dinosaur period would struggle to survive outside of a controlled lab environment today.
"While it's highly unlikely that most dinosaurs could survive in today's world, some, particularly those with adaptations for warmth and potentially efficient respiration, might have a chance. The immediate challenges for dinosaurs would include obtaining enough oxygen and adapting to cooler climates, especially compared to the warmer conditions they evolved in.
Here's a more detailed look:
- Oxygen:
The current atmosphere has about 21% oxygen, which is lower than during the Mesozoic era when many dinosaurs lived. This could be a significant hurdle, especially for larger dinosaurs.
- Temperature:
Many dinosaurs evolved in warmer climates, and our planet has cooler seasons and colder nights that they wouldn't have experienced.
- Adaptations:
Some dinosaurs, like the feathered ones (Velociraptors and kin), might have been better equipped for the current climate due to their insulation, while larger dinosaurs like sauropods might face more challenges.
- Coexistence:
Even if dinosaurs could survive, they might not coexist peacefully with humans and other modern life forms, especially if they are large predators.
- Climate change:
The rapid rate of climate change today could also be a significant challenge for any dinosaur trying to survive, particularly for those with limited ability to adapt to new conditions.
In conclusion, while some dinosaurs might theoretically have a chance of surviving in today's world, there are many factors that would make it extremely difficult for most of them to thrive."
