I thought this post was appropriate considering that this goes hand in hand with Bob's post about the shark fossil.
Here is the link and some interesting key excerpts. Enjoy!

"What most surprised Fuchs and his colleagues Giacomo Bracchi and Robert Weis was how similar the specimens are to modern octopus. "These things are 95 million years old, yet one of the fossils is almost indistinguishable from living species," Fuchs said."
"It's hard enough to find fossils of hard things like dinosaur bones. Now scientists have found evidence of 95 million-year-old octopuses, among the rarest and unlikeliest of fossils, complete with ink and suckers.
The body of an octopus is composed almost entirely of muscle and skin. When an octopus dies, it quickly decays and liquefies into a slimy blob. After just a few days there will be nothing left at all. And that assumes that the fresh carcass is not consumed almost immediately by scavengers.
The result is that preservation of an octopus as a fossil is about as unlikely as finding a fossil sneeze, and none of the 200 to 300 species of octopus known today had ever been found in fossilized form, said Dirk Fuchs of the Freie University Berlin, lead author of the report."
" Both the anoxy [absence of oxygen] and a rapid sedimentation rate prevented decay."
