The earliest known fossil vertebrates were heavily armored fish discovered in rocks from the Ordovician Period about 500 to 430 Ma (megaannum, million years ago).

What are the oldest vertebrate fossils?
A tadpole-shaped fossil, believed to be the oldest vertebrate ever found, has been uncovered by a farmer in a rugged range of hills in southern Australia. The fossil, of a 26-inch fishlike animal, is believed to be at least 560 million years old.
What are the oldest animal fossils?
890-million-year-old sponge fossil may be the earliest animal yet found. A set of curious fossils may be ancient sponges—relatives of the great bathing sponge shown here—which would make them the oldest fossilized animals ever found.
What is the oldest fossil ever found?
A geologist in Canada may have discovered fossils of ancient sponges dating back 890 million years, 350 million years older than the oldest undisputed sponge fossils. The fossilized structures found in rock samples potentially show sponges that existed in underwater reefs millions of years ago.
Where are vertebrate fossils found?
Animals with backbones are called vertebrates. They include reptiles, amphibians, fish, birds, and mammals. In many western states, vertebrate fossils, such as skeletons of dinosaurs, camels, and saber-toothed tigers, are common in Mesozoic and Cenozoic rocks.
What is the oldest vertebrate fossil and what is its estimated age?
The earliest known fossil vertebrates were heavily armored fish discovered in rocks from the Ordovician Period about 500 to 430 Ma (megaannum, million years ago).
What is the first vertebrates scientific name?
Vertebrates originated about 525 million years ago during the Cambrian explosion, which saw rise in organism diversity. The earliest known vertebrate is believed to be Myllokunmingia.
What continent have the oldest fossils been found on?
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.
Which animal is the oldest?
Oldest animal ever
The longest-lived animal ever discovered is a quahog clam, estimated to be 507 years old. It had been living on the seabed off the north coast of Iceland until it was scooped up by researchers in 2006 as part of a climate change study.
Which is the oldest fossil in India?
Researchers believe they have found the first-ever fossil in India of a Dickinsonia —the Earth's 'oldest animal', dating back 570 million years — on the roof of what's called the 'Auditorium Cave' at Bhimbetka. The find has been published in the February edition of Gondwana Research, an international journal.
How do the ages of the oldest fossils compare to the age of Earth?
How do the ages of the oldest fossils compare to the age of the Earth? The oldest fossils known are about 3.5 billion years old. Earth is about 4.6 billion years old. There may have been no life on Earth for its first one billion years of history.
What type of organism is found as the oldest?
However, the oldest, precisely measured organism living on Earth today remains, for now, a Great Basin Bristlecone pine tree. Pando the quaking aspen and Antarctic glass sponges could be much older but their ages are assumed from indirect measurements and educated guesswork.
What is the age of invertebrates?
The Paleozoic has been called the Age of Invertebrates because of the rapid development of invertebrate animals during that time.
When did vertebrates first appear in the fossil record?
The vertebrates first appeared in the fossil record, as jawless fish, approximately 550 million years ago at the start of the Cambrian period.
What is a vertebrate paleontologist study?
Vertebrate Paleontology is the study of ancient animals that have a vertebral column including fish, amphibians, reptiles, birds, and mammals. Vertebrate paleontologists are best known for their work with fossils. ... Our department provides the backbone of the Age of Mammals exhibit, currently on display.
Where are the oldest fossils found in rock layers?
Basically, scientists have learned that rocks are stacked in layers containing fossils with the oldest fossils at the deepest layers, and the youngest, or most recent fossils, near the top. It's as if rock layers are a vertical timeline.
Where did researchers find the oldest fossils?
Researchers at UCLA and the University of Wisconsin-Madison have confirmed that microscopic fossils discovered in a nearly 3.5 billion-year-old piece of rock in Western Australia are the oldest fossils ever found and indeed the earliest direct evidence of life on Earth.
