New deep-sea organism may re-write the phylogeny of life on Earth.

New deep sea mushroom-shaped organisms discovered -- ScienceDaily

This came out a week or two ago, but I thought this would be a good place to share it.

For those who wish to know, cnidarians are the stinging-celled animals (sea jellies/jellyfish, corals, hydrozoans, and anenomes) and ctenophora are the "comb-jellies", which, although quite similar to the cnidarians, are a separate group that may have been the sister group to all other animals.

These tiny mushroom-shaped animals may very well be the last surviving members of the group that gave rise to the ctenophores or the cnidarians, making them one of the oldest living ancestors to all animal life, and one of the last surviving examples of life from the earliest stages of Earth's biosphere.
