DINOSAURS ARE COMING BACK PEOPLE! JURASSIC PARK ALERT!
Either that, or even more giant elephants…
A strawberry-blond (yep, strawberry blond!) woolly mammoth was discovered preserved in ice in Siberia.
Researchers state they found
Princeton University geoscientists Adam Maloof & Catherine Rose identified fossils of soft-bodied animals from approximately 577 million years ago to 542 million years ago.
Or at least they think the fossils are from animals - that's only their "best guess."
The fossils were found in Australia and the results suggest that primitive sponge-like creatures lived in ocean reefs all those years ago.
The research suggests that the organisms were about the size of a small fingertip and had weirdly shaped bodies with a huge network of internal canals.
Here's what a scientist said:
"We were accustomed to finding rocks with embedded mud chips, and at first this is what we thought we were seeing. But then we noticed these repeated shapes that we were finding everywhere – wishbones, rings, perforated slabs and anvils. We realized we had stumbled upon some sort of organism, and we decided to analyze the fossils. No one was expecting that we would find animals that lived before the ice age, and since animals probably did not evolve twice, we are suddenly confronted with the question of how a relative of these reef-dwelling animals survived the 'snowball Earth.'"
The 'Snowball Earth' is the theory that the entire globe was frozen solid at one point before 650 million years ago.
Images recreated from their finding have led scientists to believe these fossil remains belonged to a spongelike creature. Previously, the oldest known and undisputed fossilized sponges date to around 520 million years old.
History is being made, people.
But are we sure those (above) are fossils? They look like pizza to us - ha!

Thank evolution for birds!
A long time ago
in a land far, far away, GIANT insects roamed the Earth's skies with unparalleled size and freedom.
How big are we talking? Their wingspan was the size of a modern-day HAWK!
Researchers believe that the insects became massive due to the large levels of oxygen in the atmosphere some 300 million years ago.
The data shows that the higher the oxygen level, the larger the insects.
But things changed.
Around 140 million years ago, birds started evolving and learned how to fly. With better aerodynamics and predatory skills, the birds began competing with the insects for prey, and soon the birds began eating the giant insects as well.
80 million years later, bats also started to evolve and along with further evolved birds (and the possible arrival of an asteroid), dinosaurs and the giant insects became extinct.
Again, we can't thank evolution enough!
Could U imagine insects the size of modern birds in the sky?!?!?!
