New annelid worm from the Burgess Shale

[Halichoeres]

The lagerstätte that never stops producing now yields a bunch of specimens of a new genus and species of Cambrian polychaete (think fireworms, ragworms, and bobbit worms). If you're interested in the origins of head segments of ecdysozoan taxa, you'll find some of the authors' hypotheses particularly interesting.

It's strangely... unstrange for a Cambrian lifeform. It looks like something you could find today.

[Faelrin]

That's like one of the most fabulous looking worms I've seen yet. The fossil is a pretty good find too, but I suppose this kind of preservation is no stranger to the Burgess Shale.

[Megalosaurus]

Great find!!
Now I need a model of it.

[Halichoeres]

Great find!!
Now I need a model of it.

That's almost always my first thought

[Neosodon]

That's quite an impressive fossil. Looks almost like it could make a tooth brush.
