Fossil ID Help

[FSL1]

Hi,

 

Here is another find and a newbie ignorance question.  I located on private land, in a wash, dried mud and sand.  Mojave Desert near Barstow, California.  Prehistoric bones have been found through the area.  It is not a heavy as other rocks of like size, dark color, and the end broken open looks different than a rock.  I thought petrified wood was a possibility, but it look nothing like the pieces of petrified wood I have. It doesn't feel spongey, but looks it a bit. It has a bone-type shape. I have not cleaned it yet, don't want to ruin it if I got lucky. 

 

Planter of keeper?  Its probably petrified trash...

 

Thanks for the help!!

Not trash. May be fossil palm root.

Thanks!  That's interesting, I'll do some research on that in the area.  Appreciate your reply.
