Marine snail fossil on Mars

[John Kierein]

Here's what a marine snail fossil looks like.

Look at the foreground rock here from Mars Spirit:

Look at the foreground rock...

Well, you're going to have to circle it or something because that's all I see...a bunch of ordinary rocks...

...and why is this posted in Astronomy???

...the idea of a "snail fossil" on Mars strikes me as something that should be posted in Against the Mainstream...

John: are you pointing out the rock all the way at the bottom of the frame, just right of center? I'm not seeing any resemblance.

In any case, this would indeed be more appropriate in ATM, so I'll move it.

I think I see what he's talking about. I've enhanced the image slightly and circled the relevant area.

I have developed a theory that would explain the presence of earthlike snails on Mars, but I am not yet ready to present it, as the theory would call for modern Martian snails to be descended from snails of much larger size, and I have not been able to find any evidence of such embiggened ancestors. However, it may be the case that I am looking too closely at the problem, so I will consider presenting more when I have had a chance to stand back and get a broad overview of the available evidence...

Thats funny. Nice pic. When I first looked at it, I was mumbling about how ignorant somebody must be to think they found a shell in your circle then I looked a little to the left.

I see two things in this picture.

And one of them is Jack.

Well, I'm certainly impressed. Do you happen to know Maksutov?

John's example, however, is far less impressive.
