Having found which way is up...

Further discoveries seem to have revealed which end was which... And like you might expect Hallucigenia is even weirder. :)

Yeppers, from what I've heard that was exactly why. It's an example of why the Burgess Shales were such a great find. Hallucigenia was possibly the weirdest of the lot, mostly because without any idea of which way was up, or what way was in front, or even if it wasn't a small part of a far larger animal that came off. But there were a lot of interesting critters to be described.
