Large stone. There is a fossil trilobite in the top left hand corner and behind it a track where it has moved across the ground.

From the Museo di Storia Naturale in Venice.

Nifty!

And then it just stopped. So strange.

I assume, at that point, some ocean floor event dumped a whole load of slightly different mud and silt on top of it.

From:

Then its tracks would have been erased, though, right?. Maybe it dried up in the sun on a spot that evaporated.

From:

Well I can't claim to be an expert on fossilisation, but my impression is that if it was a different type of silt or whatever then two different types of rock would form that would erode at different rates - hence trackway but I don't actually know and my tame sometimes-digs-up-fossils person is in Japan.

Cute! I like trilobites:)

From:

purplecat

I do too, though I'm never 100% certain I'm spelling them correctly...

Cool!! Trilobites are adorable :-) *takes opportunity to use appropriate icon*

Although I have to ask, how do they know those are trilobite prints? ieditignore the silly question, I spotted the culprit in the pic after I'd posted the comment.

LOL! Yes. Little teeny tiny trilobite in the corner.
