Chunk of Fossilized Bone? w/One Sawn Face

Pic 1 is the cut face, which is ~3" top to bottom. Its length is roughly the same; pic 5 is the other (natural) end. Its weight is ~24 ounces. The pics are all in bright sunshine.
It has been tentatively ID'd as Dinosaur by a learned person, but 'tho I'm not inclined to doubt their assessment (which was solely based on the segmented nature of the linear features, she admitted), I thought to show it to y'all, an' hope for a confirmation or rebuttal of that opinion. If nothing else it is a most unusual item, worthy of your perusal! Thanks for lookin'!

 

looks like fossilized / petrified wood..

 

That’s petrified wood, I’ve got some. You can see the phloem xylem and cambium.

I did tree structures long ago……

 

I don’t know enough to really comment on what it is,but it has an interesting look. The first photo really captures the imagination.

 

I'll happily take your word for all that, Bear...'tho I'll have to do some research about those three descriptors...of things you can see but I've ne'r heard of. Thanks!

 

as Dinosaur by a learned person,

palaeontologist ............ she aint !

on the other hand...I've known about hard wood..... since I'm 13....

 

Gee...thats a long time, Komo! Can you offer a species for this million year old treen?

 

I get a poplar vibe......

where did u get it?

 

Maybe 8-10 years ago, at a flea market locally (extreme NW corner of the US map); fellow said he didn't know anything about it, except he got it in North Dakota. He was selling all manner of rocks, none recognizable to me...cheap! So, for now (an' maybe forever); poplar it is!

 

my Dad loved to fish in Neah Bay..

 

unless u mean Blaine WA. , which I've been to..

 

I'm a wee bit east of Neah Bay...in Port Angeles, gateway to Hurricane Ridge.

 

nice country out there !!!

 

They’re often conifers or related species, which is what this looks like.

 

I got the same impression. Not that I'm a specialist.

 

Howdy, Neighbour! We see the lights of Port Angeles from Dallas Road when out for a "scenic drive!"

 

So...where, if at all, does poplar fit into this?

 

Poplars are deciduous, shortish lives, fast growing. They’re not coniferous.

 

Yeah...I understand that. Was referring to Komo's suggestion, an' your mention of the phloem xylem and cambium. Thanks...

 

Ah, gotcha. All trees have cambium, phloem and xylem, but it’s the way they’re laid down that can be distinctive. Those very fine structures in your piece look more like a conifer than anything.
