The sudden disappearance of dinosaurs has puzzled scientists for years. Several theories attempt to explain this mass extinction event.

17. One popular theory suggests that a massive asteroid impact caused the extinction of dinosaurs.
18. Another theory proposes that volcanic activity led to drastic climate changes.
19. Some scientists believe that diseases could have contributed to the extinction.
20. Climate change and shifting continents may have also played a role in the dinosaurs' demise.

Dinosaurs and Modern Birds

Birds are considered the closest living relatives of dinosaurs. This connection offers fascinating insights into the evolution of these creatures.

21. Archaeopteryx is a famous fossil that shows the transition from dinosaurs to birds.
22. Modern birds share many features with theropod dinosaurs, such as hollow bones.
23. Feathers, once thought unique to birds, have been found on several dinosaur species.
