I'm trying to understand. Answer the questions that have been offered to you about the nature of this beast. How does it digest rocks, for example? Why does it leave skin but no skeleton, when bones and teeth are so much more easily preserved than soft tissue? How was the skin fossilized? Was it a cast or was it mineral replacement or some other kind of fossilization process? Where is the fossil lineage for this beast? How does such a large beast fly, especially weighted down by rocks in its tummy?
Have been chewing over your questions, Tricky, contemplating a reply.
Particularly, whether there would be any point in a reply.
I have also realised how much I don't know. See, I can say "don't know" too.
So, as to your questions:
How does it digest rocks?
From observations of the feeding sites, I have deduced that it mechanically breaks the rocks with its head or jaws. I believe there is some form of caustic saliva. I also find evidence of extreme heat.
Many years ago I worked on a blast furnace, and saw used refractory bricks that showed similar effects of heat, so it is pretty intense.
As to the actual digestion......... "don't know".
Why does it leave skin but no skeleton?
I don't know (there is those words again) if it has a skeleton. This is not a carbon based vertibrate, or in fact a life form that resembles anatomically anything "known".
The nature of the "skin"?
This is the actual outer casing of the creature.
The creature has a body based ,I believe, on the element silicon.
The skins are discarded in either a cleansing and/or growing process.
I have noticed differences in skins that appeared to be the result of differences in age. I also noticed that the creature appeared "relieved" to have discarded the old skin.
For the most part the "skin" comes off ,semi solid and intact. Although I have found the odd seperate scale.
It is sufficiently pliable, when discarded, to mould to the shape of the underlying material. It is probably the consistancy of soft putty.
Once discarded the silicon then solidifies into small crystals and creates the material referred to as sandstone.
Where is the fossil lineage?
No fossil lineage with this creature, Tricky. It did not "develop" on this planet, but passed through as part of a regular migration.
How does it fly?
I am a bit vague on this one. At a guess, it has something to do with magnetic fields. To get to this planet it had to soar on the solar winds,......... I think.
Well, I am not sure if those answers fit within the parameters of "what we know about the world", but I have been chopping out thistles all day, I'm tired and cranky, so that's the best I can do.
