Sponge Fossils Could be the Most Ancient Animal Life Ever Discovered

A Canadian scientist (Sponge Fossils) thinks she could have discovered proof of the earliest known animal life, according to a study in the journal on Wednesday, July 28, 2021.

The study on a distant Northwest Canadian mountainside takes back 890 million years.

Elizabeth Turner, a geologist, found that fossils of old sponges, one of the most prehistoric life-kinds, are nearly 350 million years earlier than all other sponge fossils discovered till now.

Suppose researchers confirm the study, carried out in a region of the Northwest Territories only reachable by a helicopter that was underwater in the past. In that case, it could fundamentally change outlooks on evolution.

What did the study tell?

A lecturer at Canada University, Turner, discovered proof of sponges hidden in the reefs which are approximately 890-million-year-old.

She said that the characteristics of the material are similar to the corpses of much younger corpse fossils of sponges.

The assumed fossils she discovered were just a centimetre (0.39 inches) broad.

She also said that they would have been inconspicuous and tiny, existing in indistinct nooks and crannies beneath the surface of the reefs.

Why is the discovery evident?

There is very tiny fossil proof of sponges prior to Cambrian period 540 million years ago.

Considering the report inputs are true, the sponges would have survived 90 million years ahead of the “Neoproterozoic event” through which researchers think huge extents of oxygen raised in the atmosphere offering path to animal life.

Turner said that if she is right in her understanding of the material, the oldest animals emerged prior to that event and may have been broadminded of moderately low levels of oxygen, compared to recent conditions.
