The "Song of Anomalocaris" is, well, a complete fabrication made up out of my own
head while sitting on the tractor last week (or maybe the week before), mowing
the back field and steaming to a nice lobster red color.  I was singing the
"Amphioxus Song" at the time, when all of a sudden some verses from
"Song of Anomalocaris" shimmered into my brain like a Cambrian predator sliding
into a lagoon.  After passing through several transitional forms, the "Song of
Anomalocaris" evolved into the following:

   The true history of "Song of Anomalocaris" is clouded by the
  passage of time, but then what do you expect from an epic
  poem from 600,000,000 years ago?  The few surviving fragments
  have been collected at the University of Ediacara by Professor
  Chris Heiny.  These fragments indicate several properties of
  the "Song": it was extremely long (at least 12 volumes of
  indeterminate length); it was a mix of an eclectic variety
  of poetic styles (blank verse, haiku, iambic pentameter,
  limerick, epic alliteration are found among those fragments
  known) and a little bit of prose; it mostly deals with life
  as a predator in the Cambrian seas, from a variety of points
  of view.

  Professor Heiny has intermittently published bits and pieces of
  the "Song", usually as a .sigs on his postings, which has led to
  a bit of criticism.  Professor Heiny deflects this by pointing to
  such precedents in the field as the Dead Sea Scrolls, where the
  contents of the find are published only in driblets over many
  decades.

  The length of the "Song of Anomalocaris" is felt to have great
  significance, but there are two opposing viewpoints on this which
  has resulted in no small contention.  The first viewpoint, espoused
  by Professor Heiny, is that the very length of the epic
  is intended to convey the awesome majesty and slow passage of time.
  The other viewpoint is that Professor Heiny has deliberately
  overstated the length in order to inflate the apparent importance
  of this find, which he hails as "the foundation of paleopoetics",
  the field of the study of old poetry.  The very fact that the
  "Song" is divided into volumes, cantos and verses indicates
  either that it is very long or that Professor Heiny has a
  vivid and overly ambitious imagination.

  In his efforts to complete the "Song of Anomalocaris", Professor
  Heiny urges all those finding fragements to forward the fragment
  (or at least a copy of it) to him for analysis and inclusion in
  the collection.

So there you have it.   That's the summary of the story of "Song of 
Anomalocaris".  Contributions to the song (either in the form of fragments
any of you may discover, monetary support for the research, or beer) are
most welcome.

"Then spied he the Pikaia, and the Hallucigenia,
but Pikaia was faster, and slipperier,
So Anomalocaris got a crunchy lunch,
and by this did save the world from domination 
by Extremely Silly Looking Creatures."

Sanctacaris! Sanctacaris!
Sanctacaa-a-a-a-aris!!"

"Hungrily cruising
The Anomalocaris
Looks for arthropods."
      'Song of Anomalocaris' vol 4, canto 1, verse 72

"In the summer waters, the Anomalocaris
basks in the warmth, dreaming of
contingent futures, of the futures that
might be or might not be, of great
civilizations, mighty structures, works
of art and literature, of the culture
built by the many limbed creatures that
will crawl from the sea, of their
deeds, their loves, their wisdom -
an entire society dedicated to the
sound of the universal "O".  Serene
in its vision, it passes Pikaia to
to munch a trilobite."
    'Song of Anomalocaris' vol 2, canto 8, verses 36-37

"You are lying, Ted!"
Shrieked Mrs Anomalocaris,
"Liar,
     liar!
         LIAR!
You are a liar, Ted!
You were mating with that _nathorsti_ tramp again,
Weren't you, Ted?  Liar!"
And then she threw the platter of trilobites at him.
