Coral found on Images from the Mars Perseverance Rover

Images from the Mars Perseverance Rover Library:

Looks like there's fossilised pieces of coral all over the place 
It could be some volcanic rock remains also, but to me it looks like coral.
First some examples of fossilised coral found on Earth:




The next images are from the Perseverance Raw image library:

Shouldn't this be big news?  
Until now I have not heard or seen anything about it in the media.



Logically would be to assume the rocks are some lava deposit with bubbels.
But the longer I look, it looks more like fossilised coral.
Didn't they land in a ancient lakebed to search for signs of life?

NASA's $2.7 billion Perseverance rover has made a precise landing on the floor of Mars's Jezero crater, which scientists believe was filled with water 3.8 billion years ago. Two kilometers away sits the rover's primary target: a fossilized river delta, created as muddy water spilled into the crater—ideal for preserving signs of life. But before Perseverance starts the long climb up into the delta, to drill samples that will eventually be returned to Earth, it will examine the rocks beneath its six wheels. The rover landed near outcrops of rock layers that may have originally been laid down before and after the lake and the delta. The NASA team will probe these rocks for their origin; if volcanic, the radiometric dates derived from them could provide clues to the nature and timing of the brief period when water flowed—and life might have flourished. First, the rover will continue its monthlong commissioning phase and then deploy its attached experimental helicopter, Ingenuity, for the first rotor-powered flight on another planet.

It certainly looks like coral m8.
Will probly announce it after 5 years studying lol.

It looks like coral, but maybe it's volcanic rock after all.
I forgot to look for volcanic rock with bubbles samples for comparison also.
Now I see how much it is similar to each other, I'm not sure.
It could be one or the other, both even, impossible to tell from a picture.

407 new ones got posted today, will be checking regulary coming days.
Untill I get bored from watching rocks and sand.
