It occurred about 440 million years ago, at the end of the period that paleontologists and geologists call the Ordovician, and followed by the start of the Silurian period. The first mass extinction is called the Ordovician-Silurian Extinction. At least 900 species have gone extinct in the last five centuries. More than 99% of the four billion species that have evolved on Earth are now gone. How many animal species have gone extinct?Įxtinctions have been a natural part of our planet’s evolutionary history. that there are around 2 million different species on our planet** – then that means between 200 and 2,000 extinctions occur every year. If the low estimate of the number of species out there is true – i.e. These experts calculate that between 0.01 and 0.1% of all species will become extinct each year. Since then, the dodo has nestled itself in our conscience as the first prominent example of human-driven extinction. With their penchant for hunting, habitat destruction and the release of invasive species, humans undid millions of years of evolution, and swiftly removed this bird from the face of the Earth. Sabre-tooth Cats were carnivores named for the elongated bladelike canine teeth, which in some species were up to 50cm long. Often called Sabre-toothed Tigers or Sabre-toothed Lions, they existed 55 million to 11,700 years ago. Which type of animal became extinct many millions of years ago?ġ.
