Yes. There have been several episodes of mass extinction. The worst was at the end of the Paleozoic era. The most famous came at the end of the Mesozoic, when the dinosaurs disappeared. Nature is cruel.
Of course, some people say that species have not really become extinct, but merely evolved into different forms.
What else can I help you with?
What is the organisms that once lived on earth but all of their kind have died out?
The answer is Extinct!
What is organisms that once lived on earth but all of their kind have died out?
The answer is Extinct!
Organisms that once lived on earth but all of their kind have died out a dead species?
A species that has entirely died out is considered extinct. An example of extinct species are the dodo, saber-tooth tigers, woolly mammoths, Canary Island giant rats, Cape lion, and the Red Rail.
The observation that organisms arise in locations where similar extinct organisms lived is referred to as what?
Biogeography
What type of organism is no longer exists and will never again live on earth?
Organisms such as dinosaurs, dodo birds, and woolly mammoths are extinct and will not reappear on Earth. However, it is possible that through cloning or other advanced technologies, we may be able to bring back some extinct species in the future.
Fossil evidence indicates that most extinct primate species lived in trees?
false
Dinosaurs lived about a million years ago True or false?
false (They became extinct about 65 million years ago.)
What happened to most species that lived on earth?
they got extinct
What animal species are extinct?
just about every one. 90% of all creatures that have lived on earth are extinct.
How long have unicellular organisms have lived on Earth?
they have lived for up to millions of years
What organisms in fossils are now extinct?
99% of all organism who lived once are now extinct, so a list would be more than extensive! Dinosaurs are the big fossils. Mammal fossils are big too. Human and proto-human fossils may be the biggest things in fossils ever.
What has happened to most organisms that have ever lived on earth?
They have or are fossilizing.
