was the manta ray considered extinct? Giant manta becomes the first manta ray to be listed as an endangered species. The conservation status of the giant (or oceanic) manta ray (Mobula birostris) has been uplisted today to Endangered on the International Union for the Conservation of Nature (IUCN) Red List of Threatened Species.
What extinct species have been successfully cloned? Scientists have successfully cloned an endangered black-footed ferret, using preserved cells from a long-dead wild animal. This is the first time any native endangered species has been cloned in the United States.
Has there been a successful animal clone? On July 5, 1996, Dolly the sheep—the first mammal to have been successfully cloned from an adult cell—is born at the Roslin Institute in Scotland. Originally code-named “6LL3,” the cloned lamb was named after singer and actress Dolly Parton.
How many species have been successfully cloned? Since then, scientists have cloned more than 20 species—from cows to rabbits to dogs—using this technique, but the Chinese effort marks the first time that non-human primates have been cloned successfully in the same way.

when did buffalo go extinct in north america?
Once roaming in vast herds, the species nearly became extinct by a combination of commercial hunting and slaughter in the 19th century and introduction of bovine diseases from domestic cattle.

Was there a mass extinction in the Silurian period?
The series of extinctions that occurred during the Ordovician and Silurian periods between 445 and 415 million years ago wiped out as much as 85 percent of all animal species on Earth. It was the second largest mass extinction in history, coming at a time when nearly all existing animals lived in the oceans.
