Wiwaxia is a genus of soft-bodied animals that were covered in carbonaceous scales and spines. Wiwaxia fossils – mainly isolated scales, but sometimes complete, articulated fossils – are known from early Cambrian and middle Cambrian fossil deposits across the globe. The living animal would have measured up to 5 cm (2 inch) when fully grown, although a range of juvenile specimens are known, the smallest being 2 millimetres (0.079 in) long.
Wiwaxia’s affinity has been a matter of debate: researchers were long split between two possibilities. On the one hand, its rows of scales looked superficially similar to certain scale worms (annelids); conversely, its mouthparts and general morphology suggested a relationship to the shell-less molluscs. More recently, evidence for a molluscan affinity has been accumulating, based on new details of Wiwaxia’s mouthparts, scales, and growth history.
This article concentrates on the species Wiwaxia corrugata, which is known from hundreds of complete specimens in the Burgess Shale; other species are known only from fragmentary material or limited sample sizes.
Well I met the man who killed my mother
He put holes inside her arms
No they were not marks of stigmata lord
Just a drug pumping empty heart
Well I met the man who took my father
Put him in jail and locked him away
Well they say he forgot his children lord
He might remember us again someday
I blame the devil
Well I met the man who killed my grandmother
He took her mind as the shotgun blew
A year later my grandfather followed her
He’d had enough and shot himself too
Well I met the man who took my good friend
Oh, but he was only seventeen
I saw him laying in a cushioned coffin lord
It wasn’t him staring back at me
I blame the devil, what else could it be
I blame Jesus he ain't answering me
Don’t call me depressed, don’t call me sad
I’m giving up on this life I had
Well I met the man who raped my childhood
Oh well we were never young it’s true
But when everyone around you keeps dying lord
What the hell are we supposed to do
Well I met the man who took my sister
In a new family she will stay
And it’s true that my mother’s a sinner lord
She let another family fade away
I blame the devil, what else could it be
I blame Jesus he ain't answering me
Don’t call me depressed, don’t call me sad
