9 Thankfully Extinct Animals

1. Tyrannosaurus Rex

The Tyrannosaurus Rex was one of the largest carnivorous dinosaurs to ever exist. Its extinction allowed for the diversification of other species in the Cretaceous period.

2. Velociraptors

While popularized by movies like "Jurassic Park," these predators could have posed a threat to human ancestors if they were still around.

3. Saber-Toothed Cats

These large, powerful predators with massive canine teeth would have been a significant threat to both ancient humans and other animals.

4. Giant Ground Sloths

These massive herbivores could have had a devastating impact on plant ecosystems if they were still around.

5. Dodo Bird

The flightless dodo bird was easily hunted by humans and other animals, contributing to its extinction. Their disappearance allowed other species to thrive.

6. Woolly Mammoths

These large herbivores would have had a substantial impact on the environment and would have been challenging to coexist with if they still existed.

7. Giant Irish Deer

These massive deer with enormous antlers could have posed a risk to both humans and the environment if they were still around.

8. Tasmanian Tiger

While the loss of this unique marsupial is unfortunate, it's better for modern ecosystems without competition from a large predator.

9. Glyptodonts

These ancient relatives of armadillos were large, armored herbivores that could have had significant effects on ecosystems if they were still alive.
