According to a study published in the journal Nature, the world’s oldest animal fossil ever known was discovered in Canada recently. The fossil belongs to a sponge that lived 890 million years ago.
We still don’t know much about our planet Earth, which is thought to have formed more than 4.5 billion years ago. Among these unknowns is the subject of how old life on Earth is. A recently found fossil has become one of the biggest indicators of how old life on Earth is. canalisationengorgee
According to research published in the journal Nature, a fossil has been discovered in Canada that will represent the oldest body fossil evidence of animals known to date. The fossil provides the first physical evidence that animals arose before the epoch and survived through the glacial periods of the Cryogenic era.
The discovered fossil is described as a ‘spongy fossil’. While most fossil records first appear in the Cambrian period, 541 million years ago, sponge fossils can be dated back 350 million years, according to the study. The newly found spongy fossil is said to date back 890 million years. This makes this fossil the oldest animal in the world.
In addition, an important point is highlighted in the research published in Nature. Geologist Elizabeth Turner stated that animals have a very, very old and poorly preserved history. On the other hand, Nature noted that some scientists need more information to say that the fossils found are sponge fossils.
