Fossil Long Bone Fragment?

[DDiMatteo]

I've heard that AZ has no dinosaur fossils, but this looked like a piece of a long bone with marrow. Anyone ID?

Thanks, Dennis

hi dennis -

welcome to the forum.

the picture doesn't look like bone to me. it looks like a void in rock was filled partially with a mineral like dissolved silica, and then the internal cavity was lined/stained with precipitated iron-based mineral. if you could show a picture of the "back" of the thing to see that texture, i could be more certain that it isn't bone, but i don't see the characteristic of "spongey" or cancellous bone that is usually visible.

regards,

tracer

Thanks for the link CreekCrawler!

I thought that i saw somewhere that there were not any intact fossils found in AZ just footprints. Thanks for getting me straight..regards, Dennis
