A spongelike structure discovered in exposed 890-million-year-old rock in Canada's Northwest Territories
may be the oldest known fossilized animal body, according to a study whose findings will likely add another controversy to longstanding debates about the planet's earliest animal life.
Whats the oldest fossil?
Stromatolites
are the oldest known fossils, representing the beginning of life on Earth. “Old” is relative here at the Natural History Museum. In collections like Mammalogy or Herpetology, a 100-year-old specimen might seem really old. The La Brea Tar Pits have fossils that are between 10,000 and 50,000 years old.
What is the oldest fossil of a human?
It is widely accepted that our species evolved in Africa—the oldest known Homo sapiens fossils were found in Morocco and date back
315,000 years ago
—and first ventured out of the continent between 70,000 and 60,000 years ago.
Who was the first human?

What was the first land animal on Earth?
The earliest known land animal is
Pneumodesmus newmani
, a species of millipede known from a single fossil specimen, which lived 428 million years ago during the late Silurian Period. It was discovered in 2004, in a layer of sandstone near Stonehaven, in Aberdeenshire, Scotland.
What was the first animal on the planet?
Earth's first animal was
the ocean-drifting comb jelly
, not the simple sponge, according to a new find that has shocked scientists who didn't imagine the earliest critter could be so complex. The mystery of the first animal denizen of the planet can only be inferred from fossils and by studying related animals today.
What was the first fossil found on Earth?
The
cyanobacteria
have an extensive fossil record. The oldest known fossils, in fact, are cyanobacteria from Archaean rocks of western Australia, dated 3.5 billion years old. This may be somewhat surprising, since the oldest rocks are only a little older: 3.8 billion years old!
When was Adam and Eve born?
They used these variations to create a more reliable molecular clock and found that Adam lived
between 120,000 and 156,000 years ago
. A comparable analysis of the same men's mtDNA sequences suggested that Eve lived between 99,000 and 148,000 years ago

What animal did humans evolve from?
Humans are one type of several living species of
great apes
. Humans evolved alongside orangutans, chimpanzees, bonobos, and gorillas. All of these share a common ancestor before about 7 million years ago. Learn more about apes.
Are humans still evolving?
It is selection pressure that drives natural selection (‘survival of the fittest') and it is how we evolved into the species we are today. … Genetic studies have demonstrated
that humans are still evolving

What was the last dinosaur fossil found?

is the new species confirmed by paleontologists in Australia. It's the biggest dinosaur discovered in Australia. Researchers in Australia have confirmed the discovery of Australia's largest dinosaur species ever found.
What is the newest fossil found?
Fossils of giant rhinos found
in China, largest land mammals ever. Fossils from two giant rhinos dating back about 22 million years have been unearthed in China, according to a study published Thursday. They are among the latest relics of the gigantic animal, which was discovered amid great fanfare early last century.
What was the largest fossil ever found?
Fossils of oldest
titanosaur
discovered in Argentina
Titanosaurs are a group of dinosaurs that may have been the largest animals ever to walk the Earth. “It is the oldest record known, not only from Argentina but worldwide.” The new discovery meant titanosaurs lived longer ago than previously thought.
What was the first animal to be extinct?
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. Since then,
the dodo
has nestled itself in our conscience as the first prominent example of human-driven extinction.
What was before dinosaurs?
The age immediately prior to the dinosaurs was called
the Permian
. Although there were amphibious reptiles, early versions of the dinosaurs, the dominant life form was the trilobite, visually somewhere between a wood louse and an armadillo. In their heyday there were 15,000 kinds of trilobite.
