Other than birds, however, there is no scientific evidence that any dinosaurs, such as Tyrannosaurus, Velociraptor, Apatosaurus, Stegosaurus, or Triceratops, are still alive. These, and all other non-avian dinosaurs became extinct at least 65 million years ago at the end of the Cretaceous Period.
Are all dinosaurs extinct?
Of course, not all dinosaurs had the privilege of being the ancestors of the brood that lives today. All of the species that we consider dinosaurs are long extinct, and plenty of lineages went extinct, too. One branch of the dinosaur family produced the oldest common ancestor of all living birds.
Can dinosaurs come back?

New fossils are being uncovered from the ground every day. … In 2020, researchers from the U.S. and China discovered cartilage that they believe contains dinosaur DNA, according to a study published in the journal National Service Review.

What was before dinosaurs?
The age immediately prior to the dinosaurs was called the Permian. Although there were amphibious reptiles, early versions of the dinosaurs, the dominant life form was the trilobite, visually somewhere between a wood louse and an armadillo. In their heyday there were 15,000 kinds of trilobite.
Will humans go extinct?
Humanity has a 95% probability of being extinct in 7,800,000 years, according to J. Richard Gott’s formulation of the controversial Doomsday argument, which argues that we have probably already lived through half the duration of human history.
Can we bring back the dodo?
“There is no point in bringing the dodo back,” Shapiro says. “Their eggs will be eaten the same way that made them go extinct the first time.” Revived passenger pigeons could also face re-extinction. … Shapiro argues that passenger pigeon genes related to immunity could help today’s endangered birds survive.
Are scientists bringing back extinct animals?
— Scientists have cloned the first U.S. endangered species, a black-footed ferret duplicated from the genes of an animal that died over 30 years ago. The slinky predator named Elizabeth Ann, born Dec. … Cloning eventually could bring back extinct species such as the passenger pigeon.
What survived the asteroid that killed the dinosaurs?
Survivors. Alligators & Crocodiles: These sizeable reptiles survived–even though other large reptiles did not. Birds: Birds are the only dinosaurs to survive the mass extinction event 65 million years ago. Frogs & Salamanders: These seemingly delicate amphibians survived the extinction that wiped out larger animals.

For decades, the prevailing theory about the extinction of the dinosaurs was that an asteroid from the belt between Mars and Jupiter slammed into the planet, causing cataclysmic devastation that wiped out most life on the planet. … The gravity from Jupiter pulled the comet into the solar system.
Can dinosaur DNA be recovered?
This speed would mean paleontologists can only hope to recover recognizable DNA sequences from creatures that lived and died within the past 6.8 million years—far short of even the last nonavian dinosaurs. But then there is the Hypacrosaurus cartilage.
Are birds modern day dinosaurs?
Today, all non-avian dinosaurs are long extinct. … “All of the species of birds we have today are descendants of one lineage of dinosaur: the theropod dinosaurs.”
Are Sharks older than dinosaurs?

That makes them older than humanity, older than Mount Everest, older than dinosaurs, older even than trees. It is possible that sharks just got lucky in the lottery of life.
