“All of today’s big cat species evolved less than 11 million years ago –just a blip in geologic time time”, yet their evolutionary tree and ancestry, remains as a mystery.
“Their ancestry is so hard for us to make out that it’s known as a ghost lineage. We simply don’t have enough fossils to understand their origins.”
How did lions evolve? The common ancestor of the Big Cats dates back 11 million years. But why is the evolutionary history of big cats a mystery?
This Earth is the home of creatures that have lived here for millions of years, some of them extant other extinct. The vast majority of our ancestors are extinct that is what evolution is about.
The key moments in the Natural History are the ones that shaped the future, that converted a mother nature possibility into a tangible reality.
So when appeared Purgatorius ceratops our common ancestor with other Hominidae?
“Around 65 million years ago, these little shrew-like creatures were climbing around in the threes of Western North America, munching on insect and fruit… But Purgatorius is was kind of mysterious because it didn’t have what we think as the classic primate traits, like forward facing eyes, or nails instead of claws.”
Purgatorius is a genus of six extinct eutherian species typically believed to be the earliest example of a primate or a proto-primate, a primatomorph precursor to the Plesiadapiformes, dating to as old as 66 million years ago.[1]

If Mosasaurus disappeared totally or gradually, one thing is true the ocean has never seen again so giant reptiles dominating the aquatic world.
Never seen again a so powerful reptile ruling the oceans.
