Cretaceous Organic Marine Deposit

[David Renaud]

I have a large assortment of various Marine and Flying Reptile fossils. Here is a sample.. 1) pair of undetermined fossil heads  2)

I’m sorry but all I’m seeing is geologic not fossil...

[Rockwood]

Agreed. I see nothing to indicate it's being fossil bone.

[Fossildude19]

Sorry, but I am not seeing any fossils here.  

I agree, these look like geologic oddities.

I see no bone texture or skull morphology to indicate these are the heads of anything.

Fellas please look again- These are not skulls rather heads. They come from saturated zones and never decomposed.

If that were the case, it would not be a fossil, but something recent. Fossils are the result of decomposition and generally replacement by minerals (exceptions include fossils in amber, and sea shells that may retain their nacre under certain conditions). Only in extremely specific conditions can soft parts retain their appearance, and these are still the process of mineralization, and generally occur in Konservat-Lagerstatte zones. 

 

However, in this case and as stated above, there is no distinct morphology to state that these are heads or skulls. There is no symmetry, and no resemblance to heads in these globular masses.

This is dumb  how do I send a picture? cant it just be simple? not everyone has all day to figure it out. how about it?

In the reply field, click on "choose files" (to the right of the paperclip icon at the bottom of the text-entry field). It should be the same process you followed to post your initial images.

As stated, that would be an incredibly rare occurrence. 

I don't see any symmetry either, or anything that would indicate these were once living things. 

I don't understand what you mean by "saturated zones", but most fossils were buried by floods or oceanic events.   

 

Where (country, state, county city?)  were these found?

 

[El_Hueso]

Very cool and unique looking rocks. I would love to have one as a fireplace mantel piece or decoration but there is nothing at all that indicates that these are fossils.

[Auspex]

Your specimens do not have an organic origin; they are sedimentary geologic oddities.
You don't have to take our word for it; contact a natural history museum in your area, and let a scientist look at them. He can explain exactly what they are and how they formed.

[facehugger]

Kinds looks like an iron concretion to me. 

 

+1 for geologic, non-fossil specimen. 

 

And why wouldn't organics decompose in a "saturated" zone? I was under the impression that sort of preservation would only occur in extremely dry areas, like arctic or dessert...

+2 for geologic, non-fossil specimen.

Hey... I work in a fossil museum...maybe not in your area, but I agree with the others...no fossils aqui.

There are indeed fossils which are preserved in unconsolidated, oxygen deprived sediments. A head preserved that way would most likely be a more gruesome site if any of the flesh survived.

Looks a lot like native copper nuggets, or if it's the lighting, some sort of slag.

[Ludwigia]

As they say, 2 heads are better than one.

[El_Hueso]

I'm honestly interested in seeing more pictures...
