Yes, that "bubble mats/rinds" warrants some closer inspection(s) and I too got the impression that this may be somewhat related to the Opportunity newberries. Smile

Sol 0275 MAHLI false color closeup of Cumberland rock, Yellowknife Bay:

with location links.

What type of rock is round with "dimples"?

Why are the "dimples" dust-free?

Er, how did all the "berry dimples" all come to be pointed up?

Colonies of specially adapted/evolved (on Mars) microbes comparable to Earth cyanobacteria colonies nicely served on corresponding microbial mats - fossil or even active. Very Happy

..or just another coincidence of Mars.

Nevertheless you can see this feature(s) all around YkB if you zoom in:

Re: 362
Yes perfect, that's some insight!
You really put the hammer to the nail here, hort:"how did all the "berry dimples" all come to be pointed up"...
If NASA doesn't reason along these lines, I honestly hope you'll get the cred for this - eventually.

Agree with MPJ.

Pretty obvious the newberries are lichen. They are symmetrical. They are "crunchy on the outside and soft in the middle." They are not hematite. They are not rocks. Not many rocks that are soft in the middle.

Sure, pareidolia some might say. My money says history will prove life was hiding in plain sight once we actually "discover" it.

I'll speculate that the "dimples" are apothecia.

Compare Hort's 362 with:

I'll even take a guess at identifying the genus: Dactylina

Sure looks alot like the "rover plastic" from Rocknest (which was surrounded by a lot of the same "rocks" we see now and at Cape York):

Here's one from Oppy (~sol 800):

Horton re your 362, Thanks and good question. We've seen multiple berries with depressions pointing up before:

Those are giant spherules that Oppy encountered on final approach to Cape York. It is reasonable to think that in both these cases the pits formed through some sort of erosion after the berries were settled in their current positions.

Opportunity sol 2668 ( Jul 27, 2011 ) closeup of reply 368 area:

I was disappointed that there was no official interest in these curious stones.

If the SAM instrument detects higher levels of organic material in a berry-rich sample from Cumberland, compared to the surrounding rock, that would be a very telling result!

Chemcam sol 0189 of peculiar rock in Yellowknife Bay:

I suspect that the Chemcam has already revealed some peculiar elemental compositions ( excess carbon? ) of these peculiar pebbles.

Hort, your post 372 fits nicely into the discussion about fruiting bodies. I do not have the dimensions of the "pebbles" but if you take a flight of fantasy one could say they look a lot like the apothecia of Monilinia vaccinii-corymbosi.

Fast stitch of MastcamR Sol 275 images - MAHLI imaging spot of re 362 is slightly below center:

Also of interest: some of that bubbles/dimples developed a crack due to some rover action(?):

Lots of additional interesting close-up imaging targets around here as well! Smile

Sol 0275 0276 MAHLI animation before and after APXS of bumpy rock Cumberland in Yellowknife Bay:

I noticed the crack too.

That the placement of the APXS broke ( tore???) a "dimple berry" implies it is very soft.

How does this square with the concretion idea?

I look forward to all the results from this rock!

#376 wow great catch this is getting more and more intriguing by the Sol.

Hort, MPj; Look at what's inside the "mouth" of the dimpled newberry.

Its getting there slowly.

Sol 0276 3D of berry "tear" on Cumberland rock, Yellowknife Bay:

Winston, here is a 3D "peek" inside the berry. The material inside doesn't look very "rocky".

Also, to my eye, the break looks more like a tear than a fracture.

Oh, to be 10x closer!

Sol 0276 3D of drill over Cumberland rock in Yellowknife Bay:

It is now the afternoon of sol 0277 so drilling should be underway - or completed. It will take a few sols to get the material to the analytical instruments.
