Bengaluru: The oldest known fossils of animals date back 541 million years, which is when animals first started to appear according to fossil record. But a new discovery seems to point to much older animal fossils that of sponges dating to 890 million years ago.
The discovery, published this week in
Nature journal by Canadian scientist Elizabeth C. Turner, identifies a possible fossil with microscopic tubular crystalline structure on rock surfaces. The pattern seemingly matches the expected pattern of fossilised protein in sponges. ....

Is This the Oldest Animal Ever Found? | Plants And Animals

Is This the Oldest Animal Ever Found?
Scientists have long been investigating the origins of life, and researchers can use genetic, molecular, and paleontological tools to do so. While there is some molecular evidence that animals first arose during the Neoproterozoic era that stretches back 541 million to 1 billion years ago, and more specifically, during the Cryogenian period, there isn t much physical evidence to prove that hypothesis. However, scientists have begun to identify what may be ancient fossilized microbes that could represent the oldest animals. Earlier this year, for example, researchers found what they described as fossils of ancient sponge-like animals that could be as much as 635 million years old. At the time, they were thought to be one of the oldest fossils of an animal ever discovered. ....
