Petrified Corn Cobs

Found these by Dilley, Tx in a corn field.  It's certainly corn but I have never seen fossils petrify this color.  I've found the same mineral as concretions in limestone.  I was curious to what everybody else thinks about them.

Not confident this is corn. You may need to post a picture of the ends to make sure. The piece on the left does not seem to have any regularity of the seed pattern.

 

There is a possibility that this could also be a piece of iron siderite concretion.

Kinda reminds me of shrimp burrows?

I think that may also be a good possibility. I've seen similar pieces like this that were marine burrows.

+1 for marine burrows. They are quite common in my neck of the woods (Mornington Peninsula),  & can range from petit to forearm size. Many of the larger varieties display this bumpy textured outer surface

Could not be corn. Corn was developed by the Mayan civilization around 5 hundred years ago from a grass.

A fact which doesn't necessarily preclude this being corn, just a fossil.

I'm in total agreement that it doesn't need to though :)

Ok, my wife has been busy cleaning up and ran into these.  I found these outside of glendive in a very yellowish matix above the Pierre Shale 11 years ago.    These are shrimp burrows.
