(Medium)   Remember the cave where thousands of specimens of prehumans were dug by small, but brave & smart women? They just concluded a follow-up expedition which sent them into holes you think are too small to fit in & in the process made the science weirder   ( medium.com) divider line

seelorq: Neat read, subby.
But they didn't mention an obvious reason why the bones were spread out..animals intent on gnawing the flesh off bones tend to move them around in the process, just like my dogs don't eat treat bones at the exact spot where I feed them. They grab-n-run a few feet away, then munch.


Oh they dealt with that in other articles and the peer-reviewed literature.  It goes to why this was such a strange find. If animals had chewed on those bones, they would have had teeth marks on them.  The bones did not. Only a handful of non-hominin remains have been found and they don't appear to be associated with the hominin remains.  That is unusual.  Hominins are pretty much always found with other animals.  And then there are the sheer numbers.  The 2013/4 expeditions found ~1550 specimens representing a minimum of 15 individuals.  Of 1550, about 300 were laying on the surface and the rest came from a 80 cm by 80 cm excavation which is a tiny fraction the size of the chamber.  This new series of excavations adds more.  It is clear that a there are many many bodies were in that chamber.  The sediments in the cave don't include anything from the nearby chambers which are chemically distinct from them plus the articulation of some of the individuals shows that they were whole before they got into the cave.  The chamber include babies, children, adults, and old. It included males and females.  And since falling into a deathtrap is a common situation for this area, that would suggest bones broken just prior to death which is not the case. (Breaks in fresh bones look different than in bones that are long dead.)  In the same cave system they found a second chamber with at least three individuals.  That second chamber is easily far enough away that it not the same event.  They found a third site, that might have have at least one more though that it not confirmed as collecting the bones might be too dangerous.  Please bear in mind that most hominin fossil finds are isolated teeth.   It is very rare to get a skull plus rest of the body.  It is extraordinarily rare to get more than one.

The team controversally suggested that Homo naledi, put the bodies into the cave after they died.

Basically, you need to get a whole bunch of them into a cave chamber without admitting scavengers, without leaving non-hominin remains, without breaking their bones, that gets a whole cross-section of the population, and without getting any dirt or gravel from the nearby chambers.

They've also found what seems to be an in-place skeleton in the dirt. The problem is they'd like to get the skeleton out in one piece but the cave's very humid and the soil's very loose. Ideally, someone out there knows how to harden the loose soil so they can carry it out in a big chunk to better document the position of the bones.

There was a thread about it a few days ago.

Holes you think are too small to fit in can be a lot of fun.

Dr. Berger did a presentation this year in Seattle in which he told the story from start to present and teased they'd have more announcements, maybe we'd hear about it in September... This whole discovery is like endless shoe drops and Berger (and his team) emphasize how much dedication and coincidence it took to find more than a tooth or a bone fragment and document their discovery so far.

He speculated that there's more caves/discoveries like this, and that he would likely leave some of the site for future archaeologists. To find this one, he and assistants had to spend years double-checking previous team's work to discover things had been over-looked, such as GPS coordinates that were wrong, etc.

I did not intend to threadjack this, I swear.  I just have impulses.

The Lesedi chamber is really, indeed, amazingly an awesome archeological find.  No jokes or innuendo.

You missed the "she is a cop" part.

If anyone was violated that night it was me.

"I got stopped by a lady cop
In my automobile
She said get out and spead your legs
And then she tried to cop a feel
That cop she was all dressed in blue
Was she pretty? Boy I'm tellin' you
She stuck my butt with her big black stick
I said "what's up?" now suck my dick
Like a ram getting ready to jam the lamb
She whimpered just a little when she felt my hand
On her crotch so very warm
I could feel her getting wet through her uniform
Proppin' her up on the black and white
Unzipped and slipped "ooh that's tight"
I swatted her like no swat team can
Turned a cherry pie right into jam"

Yet it seems remarkable to think that bodies of H. naledi might have entered the chamber by this difficult route.

Not that difficult if you have strong aku-aku
