Really not convinced... I think the authors are vastly overstating the sponginess of this fossil, and I'd have assumed instead something like a calcified alga, or amoeboid protozoan. Let's just say that if that *is* an early sponge then it certainly upsets my own evolutionary model..!

You are the sponge expert Joe New Paper out "Unusual Deep Water sponge assemblage in South China—Witness of the end-Ordovician mass extinction" : www.nature.com/articles/srep16060 sponges Arghh! Pipped! This fauna (from a different province) is something we discovered in late 2012, and we're going back to China in December to write it up..! Actually, I did have an inkling this was happening, so it's not a total disaster - we can do a lot more with the faunas than they've done, I think, mainly because we have far more material. Still - that's the first time I've been gazumped!
