445 million year old soft tissue.

Exceptionally well-preserved fossil communities are always exciting, but some are more interesting than others. A new window into the aftermath of the second-biggest mass extinction since the rise of animals is therefore very interesting indeed. The end-Ordovician crisis, 445 million years ago, resulted in 85 percent of species dying out.

A joint team of researchers from China (Nanjing Institute of Geology and Palaeontology, Chinese Academy of Sciences, et al.) and Britain (National Museum Wales) have uncovered a new fossil fauna that preserved delicate skeletons and soft tissues from the immediate aftermath of the Ordovician mass extinction. The fauna is extraordinarily diverse, with nearly 100 species found in the first phase of collecting. The surprise, though, is that this diversity is almost entirely composed of sponges.

The Anji Biota records an astonishing range of sponge species in many major groups, with a total diversity exceeding that of equivalent modern faunas.
