A couple of Nautilus

[RJB]

 Here are a couple of Nautilus I have finished up.  The small one is from the Fox Hills Formation, the bigger one is from the Pierre Shales of eastern Montana.  The really neat thing about the bigger one is that its in its own concretion.  Very very hard to find one like that!   First one ive seen!    Oh, a bit over 6 hours of prep for the bigger one.

Are those concretions found throughout the Pierre shale? Like even down here in Colorado?

Thanks everyone. 

 

FossilDude:  Concretions found everywhere in the Pierre Shales.  I think not.  Even here in Montana trying to find an area in a formation that has fossil bearing concretions is no easy task.  Ive not heard of these coming out of Colorado, but I guess there could be?
