Sorry Juan, i was unaware that octopods are members of the mammilia family, or for that matter, Kiwi or all the other animals that have come up
the answer, of course, is the last mammal that became extinque.
smart animals adapt to new challenges, dumb animals get done in. wooly mommouths were big, (and could feed the village for weeks) and had tough skin, and tusks, but they were not smart enough to outwit men armed with wooden sticks and stone spear tips. and so they are no more...
i think there are other marine animals that have copper based blood, not just horseshoe crabs and octopods.

Notice that copper is essential to blood formation in humans"
Anemia

low Copper (early) - (hypochromic, microcytic)
low Essential Fatty Acids (see our Signal369)
low Folic Acid (megaloblastic)
low Iron (hypochromic, microcytic)
low Magnesium (hemolytic)
low Phosphorus (hemolytic)
low Riboflavin (normochromic, normocytic)
low Selenium (hemolytic)
high Vitamin A
low Vitamin B6 (microcytic)
low Vitamin B12 (megaloblastic)
low Vitamin C (scurvy)
low Vitamin E (hemolytic)
low Vitamin K (hypoprothrombinemia)

and the humans were too stupid not to kill off an easy supply of food, so they had to find something else...

Latest theories suggest there was some inadvertent disease trasmission involved.

Dear Faldage: this senile citizen found your comment bafflingly cryptic. What disease from whom to whom?

Dear Faldage: I do not believe that the small number of humans with very primitive weapons
could have covered enough ground to wipe out a widespread population of any animal.
Climate change does indeed make new diseases spread. My father never had to worry about
hearworm in his hunting dogs. West Nile may be a brand new virus, that climate change may
have facilitated spread.
Men wiped out the carrier pidgeon with shotguns.Sailors wiped out the the great auk.
That is believable. I think the archaeologists are extrapolating illogically from that.

The overhunting theory was the original theory and more or less unquestioned for many years. The others are relatively recent and have been summarily rejected by those whose minds have been made up. Nobody, save you, seems to be ready to entertain the notion that it might have been a combination of ingredients.
