A vast whale graveyard + Zombie sea cucumbers

This is a density that we have not seen anywhere else in the world.

Science Friday
A vast whale graveyard + Zombie sea cucumbers

Right.

Science Friday
A vast whale graveyard + Zombie sea cucumbers

It seems like that there is a preponderance of

Science Friday
A vast whale graveyard + Zombie sea cucumbers

deathly remains of whales, right?

Science Friday
A vast whale graveyard + Zombie sea cucumbers

And that's why I think the researchers use the word necropolis to describe the mega site.

Science Friday
A vast whale graveyard + Zombie sea cucumbers

And I kind of went back and forth about in my head whether necropolis was the right word because necropolis implies human intent, right?

Science Friday
A vast whale graveyard + Zombie sea cucumbers

Of concentrating remains.

Science Friday

It's also a whale necropolis is also a fantastic band name.

Science Friday

So that's out there for somebody to grab.

But what we're really seeing is that it's an exposure on the seafloor that has skeletal remains that accumulate over hundreds of thousands of years.

Science Friday
A vast whale graveyard + Zombie sea cucumbers

I mean, think of it this way, is that some of those bones on the seafloor have been exposed sitting there for the entirety of our own evolutionary history.

Science Friday
A vast whale graveyard + Zombie sea cucumbers

So the geologic time span of...

Science Friday
A vast whale graveyard + Zombie sea cucumbers

our own species is encompassed by those lonely set of bones on the seafloor.

Science Friday
A vast whale graveyard + Zombie sea cucumbers

So if you have enough time, then you can accumulate a lot of skeletal material.

Science Friday
A vast whale graveyard + Zombie sea cucumbers

You can think of it like a cave site or like a tar pit.

Science Friday
A vast whale graveyard + Zombie sea cucumbers

These are places that end up recording a lot of remains from the outside environment, including the bones of animals that happen to live nearby or even in the cave itself or fall into a tar pit.

Science Friday
A vast whale graveyard + Zombie sea cucumbers

And these will accumulate over a long period of time.

Science Friday
A vast whale graveyard + Zombie sea cucumbers

And clearly, this is still happening today.

Science Friday
A vast whale graveyard + Zombie sea cucumbers

That's what those active whale fall sites tell us, is that whales are still falling to the seafloor and being colonized and forming entire ecosystems that are supported by the nutrients from their bones.

I have such a long bucket list of places I want to go and fossils I would love to collect.
