I'm guessing they are metal veins the rock has eroded enough to expose. Likely molten and thrown from a meteor impact explosion and cooling in existing erosion channels.

Whatever it is in the enlarged photo looks like it's lying between the legs of a big teddy bear
Here's another one, taken by the Perseverance rover on July 12, 2022.
It certainly looks biological.
But JPL seems to think that it might be a piece of a thermal blanket from the descent stage that crashed about 2 km away from this location. They aren't sure if it came off before the crash or was blown here by the Martian wind.
I’d be interested in the rock at the left also. Probably an optical illusion but it appears to have a peak sloping downward. Looks like sea shell or crab shell, something you might pick up at the beach. It seems to be perched on the crest of the sand ripple since it seems to cast a shadow there. Also like where at the top end of rock, the sand ripple veers off in another direction…..do you think that means the rock got moved to present location or was it there before the sand ripple curved away?
