Could a dinosaur survive in the forest today?

Answer 1

it depends on if it has survived to get used to our society and used to getting to the end of the Forrest and used to seeing houses or a road and cars.

if it is used to it seeing all these things, it probably could but it would need appropriately sized food which is unlikely + it would need allot of water.

if it could find all of these things it probably could survive.

More seriously, it's an interesting although hypothetical question given that they died out 65M years ago in a time of abrupt world-wide climate-change too severe for them to handle, but they left related lines in both modern reptiles and surprisingly, perhaps, the birds. They lived in tropical / subtropical conditions so in theory, had their nemesis, the mass-extinction at the end of the Cretaceous, not occurred, more-directly dinosaur descendants may have continued in suitablwe regions. We would not necessarily see Tyrannosaurus Rex or Diplodocus though, nor even the much smaller Jurassic & Cretaceous reptiles, because individual species tend to last only a few million years at most. (It's about 3M yrs on average for a mammal species; I've not seen a comparable figure for the mean life of a reptile species.)

Answer 2

No, modern forests are vastly different from the habitats that existed during the time of the dinosaurs. The climate, plant life, and ecosystem have all changed significantly, making it unlikely for a dinosaur to survive in a contemporary forest environment. Additionally, dinosaurs as a group went extinct millions of years ago.
