There seems to be a sudden rush of apparently important fossils. Workers from Bristol University appear to have focused on a spiny, slug-like starter ancestor of the Mollusca (the group to which slugs, snails, octopus and squid belong) from Morocco (https://phys.org/news/2017-02-spiny-armored-slug-reveals-ancestry.html). In appearance, it was not unlike the existing marine Chiton (above) with its armoured plates. The surprise, was the presence of spines as these are not found in modern members of the group.
