Those are the same as Yorgia-sacks /-chambers on Earth. Their size is kilometres, and the whole asteroid is full of them and so, it is or was full of life. Fetus-sack has two hands holding them, both on Earth and on Vesta, + many other fastening parts were there too, at least on the Earth. Actually a collar-shaped tissue circled the sack all over. That is propably the uterus. Study it, and you'll find it to be true. You'll see same big jaw horn, that is holded/covered by caretaking "hand", you'll see 2 direction of the stripes around the big jaw horn, you'll see big hole up there; "hand" covers it too. I'm not sure, if that is the hole to give birth. Under the big horn there is a weird "mouth"-cut. The opposite side has no horns, but a few cut-kind-of structures in smooth round curve, and 2 similar structures meet there in the middle of that side. Trying to say, that the packet has almost exactly the same structure, although it is not simple, but really quite special, I'd say even complicated.
I studied the photo many hours last night, and didn't realise first the similarity - although I had suspected from the very beginning the holes to be those ...
How I found these: 1. Knew Yorgia to be among the oldest on Earth. Saw an unclear photo of a Yorgia-stone, that I could dig into with Photoshop. 2. Checked surfaces of Mars and others. Vesta seemed weird/"unregular" already at the first glance.
The blue photos from Earth are negative-versions of a photo showing Yorgia-fossiles on a stone. Those are very very old.
Work is not done: How flat or plump was the fetus, and what kind of appearance did it have? <-- One can find them and find the answers to those questions.
How many fastening-points the sack had and what kind they were? <-- Answering to that question should not be impossible.
What was really the "thing", to what this roundish part fastened? Foam/mud/jelly with no body but some cords and fibres used the materia, that was in suitable form? Or was that surroundings some jelly-animal's back? Or jelly leaf's back? There should be a connection to a leaf-kind... or is this even older than a plant-shaped...? There are signs of community, that surrounded the sacks, and created the sacks ... community mass, but also leaves and plant-shapes... Really there are huge straight body-trees/ -trunks, that grow smaller branches... one needs to study those with time, instead of mess around with glances and foggy old & new theories. :) Nasa seems to have very good images.
Nautilus resembles these cover-chambers a lot - it came from it, in a way like "not leaving shell & keeping fetus-form"? Insects kept the chamber for birth -system, and kept the baby-form, but refused to fasten back to ground for adult-time? And there are many other questions, too.
Interesting things, those Yorgias. These are negative-pics from Earth. (In positive it's unclear, shining blond light.) Their size was only some 20 cm.
A large lake disappeared into a hole in Oregon, USA, on the first days of last May. It seemed to me, that the chamber of some 1-2 metres had been one of THOSE. There were that kind of structures on the bottom of the hole. I don't know how old the mud or mud-jelly or stoned mud-foam was round the hole, but it should have had "mother-tissue", protecting flap like a plant's part (closing the biggest openings), and several veins to the chamber.
If it was a chamber of those creatures in Oregon, the next question is: why/how can the remains suck a large lake? Where did the water go? Where the water went, some kind of roots may have had a connection to there.(I cannot know, what kind of hollow places there are down there and why ... I'd not want to dig that deep to that :) ... but Jamal in Russia comes to mind.

P.S. It may be nothing, but marks of vulcanism. Hot water & lava spitted out? Will I ever learn. This was stupid.
Or maybe all that are marks of vulcanism? I thought that up from the "flower-circled hole" came a leaf ... ... well, anyway, weird ghosts there are. At least I noticed the ghosts. Human eye doesn't see those easily.
