Possible root fossil?

[daniiy01]

Hello guys, I would like to ask you about one fossil that I found the last summer in Huelva (Spain), lower pliocene. In the area, I found bivalves, thalassinoides, gyrolithes and some crab rest. But the thing that most impressed me was the next. I asked in a Spain forum and someone told me that could be a root, but I can not find information about it on the Internet.

The dark brown part is very sensitive to touch, melts to the touch.

 

Thanks you, 

Daniel.

I think this topic should be moved to Fossil ID category. If someone can do it...

Sorry.

Looks man-made to me.

Can't be. Like I said, the zone was full of fossils and difficult to access. It looks like iron / screw and I have verified that it is not metal, and like I said, the material is very soft.

Is it possible that it's a sedimentary cast with mold? Even though the area is now deserted, there may have been human activity there in the past. How did you verify that it's not metal?

Could be.. I don't know... Remembering...we also found an ancient coin in the area but I still think it's probably a fossil, but I have no idea... I think that if it were something human, it would not be covered with stone, and all the fossils I fould were full of that kind of stone... I'm very curious 

 

By the way,  thanks for your replies.

I'm thinking ancient drill hole filled with sediment.

But that form so similar to that of a screw unbalances me... Also I thought in Nerinea gigantea but I don't think so...

I agree with Ludwigia, this is a man made iron object that has rusted to limonite. The iron cemented the sand around it as it rusted away.
