Animal life may have existed on earth millions of years before most scientific evidence show.
Geologist Elizabeth Turner recently discovered the fossil of a sponge in rock samples in northwestern Canada.
Scientists say the primitive animal’s remains could be as much as 890 million years old.
That would pre-date it from similar fossils by 350-million years.
Turner believes sponges lived in reefs in earth’s oceans at the time.
Experts say her discovery could provide a glimpse into the earliest marine animal life on earth.
The journal nature published her research Wednesday.
