A spongelike structure discovered in exposed 890-million-year-old rock in Canada’s Northwest Territories may be the oldest known fossilized animal body.

In a paper published Wednesday in the journal Nature, Elizabeth Turner, a geologist at Laurentian University in Ontario, described the branching, tubular structures she observed while examining ultrathin slices — about as thick as a human hair — of what were once reefs in a prehistoric ocean. Dr. Turner suggests the meshlike structures closely resemble the fiber networks of modern keratose sponges, also known as horny sponges, found around the world today.

However, the creatures that flourished in ancient seas may have looked quite different than those that swim through oceans today, and scientists disagree about how much and which types of evidence can distinguish animals from other forms of life—or geologic structures.
