Nebraska Fossils

[G..]

I found 2 fossils that look to be part of a jaw.  What did I find?

Hello, and a very warm welcome to TFF from Morocco. 

Can't see any bone or tooth material, it looks like fibrous calcite on limestone with veins of calcite or quartz to me.

Welcome to TFF from Austria!

 

I don´t see a fossil, its a rock (limestone?) with various vein fillings (calcite or aragonite).

 

But maybe your next specimen will be a real fossil! Keep trying!

I agree with Septarian nodule. 

Welcome from Connecticut.

one more vote for septarian nodule.  Is this from far northeastern Neb?

[Mark Kmiecik]

Not fossil, but I would be all over that specimen to get it into my collection of minerals. Very nice find.

 

I'm not pro-septarian on this one. I lean towards travertine or tufa.

Looks Septarian.

  I see said the blind man.  Looks Septarian to me. Thank you for your kind welcome, time, knowledge and pictures.  Me and Gus (my standard Australian Shepard) get lost in time when we are digging around in our creek.  Every time it rains its a new place, which I'm sure isn't lost on you all.  Glen from SE Nebraska,  Nemaha River Valley
