Recommended Posts

Hello everybody.

Yesterday i found this in the layers of hard clay, where fossils i never met before. Above this clays there are sandstones from jurassic, so i decided that this Something are jurassic too. 

So i need your help with id.

Thnx alot.

Highlander, meet non conformity, and all it's various permutations.

Paleodictyon is what came to my mind as well. You may be looking at an old, and/or, deep water, surface.

@Highlander, nice find!!! 

 

Excuse my ignorance. I learned Paleodictyon is a trace fossil. But my mind is having a difficult time imagining a creature on the seafloor making perfect hexagonal traces of its existence. Any explanation would ease my conflict.

They are thought to be farming traces (insert ichno term here). Modern ones are known, but I don't think the farmers have been observed.

Limpets had been known to return to the same spot on the rock after grazing so you can see a little depression on rocks at low tide levels where limpets had repeat returns to. But since no modern-day examples of hexagon patterns exists, it is much harder to visualizes.

What you call your "ignorance" is shared by the paleontological community. No one can figure out what makes these traces or how, even though they have been discovered in modern oceans, indicating the organism still exists!

This is incorrect.  They are still being found today, with no clues as to the makers of these marks.

If these creatures were capable of supposedly engineering these patterns to use water flow to farm food wouldn't that require more intelligence than a worm has?  The pattern looks like pre programed repetition like that of bees and ants building structures.

The creation of complex patterns need not have anything to do with intelligence.

Weird. I'm guessing a hard body animal not soft body since soft body animals are more flexible and would had makes more round shapes. Obvious this is one case of when sediment shifters made those shapes because it was the most efficient way to completely cover the ocean floor and not accidently going over the same area twice.

Very nice Paleodictyion isp.

Agrichnia are thought to be created to either collect or culture bacteria or other small food substances. Literally a small farm.

Watch an inch worm a while. The body shape would seem suited for civil engineering.

' not sure they'd make it as an M.E. though.    :Wink1:
