In their heyday there were 15,000 kinds of trilobite..

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. … Understanding the exact cause of species’ extinction can help scientists protect living animals and ecosystems.
When did the last dinosaur exist?
about 65 million years agoDinosaurs went extinct about 65 million years ago (at the end of the Cretaceous Period), after living on Earth for about 165 million years.
Are sharks dinosaurs?

What killed the Megalodon?
A new study suggests that a tsunami of cosmic energy from a supernova killed off large ocean animals – including the huge megalodon shark – 2.6 million years ago. A shower of particles may have spelled curtains for the megalodon, a school-bus-sized shark, 2.6 million years ago.
Are dinosaurs coming back in 2020?
Sometime between now and 2025. During a panel published five years as of June 9, 2020, the scientist who Jurassic Park’s Dr. Alan Grant is inspired by revealed an expectation technology to be capable of bringing dinosaurs back into existence sometime between today and five years from right now.
Are there still dinosaurs in the ocean?
For millions of years, reptiles dominated the Earth. Many that dwelled on land were dinosaurs. But no dinos swam in the seas.
What came after dinosaurs?
No! After the dinosaurs died out, nearly 65 million years passed before people appeared on Earth. However, small mammals (including shrew-sized primates) were alive at the time of the dinosaurs.
Are Sharks older than dinosaurs?
As a group, sharks have been around for at least 420 million years, meaning they have survived four of the “big five” mass extinctions. 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.
What animal is older than dinosaurs?
millipedesThey breathed air via tiny spiracles (breathing holes) in their body, much as insects do today. Some were much bigger than millipedes alive now — up to six feet long and a foot and a half wide. Fossils of these ancient millipedes are much older than those of dinosaurs, dating back over 400 million years.
Are all dinosaurs extinct?
