It might surprise you but cephalopods have a pretty good fossil record, with one major exception. If squids were swimming around in the same oceans as their closest cousins, where did all the squids go?

Thanks to Franz Anthony for the cephalopod illustrations featured in this episode! http://franzanth.com/

When a language borrows and absorbs a word from another language, the use of that word in context of the borrowing language becomes part of that language. It is therefore not correct to say "octopus is a Greek word" as much as it is to say "octopus comes from a Greek work" and in the context of octopus as an English word we can use whatever rules we'd like to refer to its plural which would preferably be the one that maintains the most consistency within our already inconsistent language. It just so happens to be the one that maintains that consistency the most is "octopuses."

If the soft tissue of squids don't fossilize well due to high levels of ammonia, isn't it odd that the other related cephalopod that is thought to not fossilize well because of this reason was already called an ammonite?

Researching further, the name was apparently coined by Pliny the Elder way back in 79 AD as 'ammonis conua', meaning "horns of Ammon" due to the fossils' resemblance to ram's horns like that depicted on Egyptian god Ammon. Pliny apparently also happened to have called a possibly non-ammonia sea salt 'hammoniacum' because of its proximity to a nearby temple of again Amun in the Roman province of Cyrenaica and Roman visitors to another ancient temple of the Oracle of Amun in Siwa oasis collected a white crystalline material from ceiling and walls that they called 'sal ammoniac' ("salt of Ammon") that, centuries later, an 18th century Joseph Priestley noted as releasing a vapor when reacting with lime that he then called ammonia.
Now squids, and in turn ammonites, are found to not fossilize well because of high levels of ammonia. Weird, eh?
(Hang on, then there's the term 'squidgy'... Nah - I'll leave it alone)

Squid is like 90% water, with a hard beak. I would assume some squid fossils have been misclassified as birds

Faster explanation: octopus live on sea floor so they dont have ammonia cuz ammonia make them float but squid jave anmonia so they can float and for something to fossilize it need low pH but since ammonia have alot of pH and squids have ammonia they dont fossilize meanwhile octopuses having no ammonia thats they can fossilize

So Octopus is a latin word, but is not conjugated in the second declination like other similar latin male nouns. This is because it came into Latin from Greek and kept it's Greek 3rd declination plural form "octopodes".

I think about how many fossils we have lost to volcanic activity, plate tectonics, wind/water erosion. We are probably missing SO much of the fossil record because of those things.
