bones, sandstone, and rocks

Recommended Posts

Strange fossil - this fossil has it all.... white solid bone (lick test>?), hardened brown non-rock like material (told possible brain encasing?), all encased in sandstone, hardened sand, and brownish marrow like substance.   When I first came across this (along with many other from Scotts Valley, CA - approx. 40-50 years ago found by my father in a ravine) Ive been attempting to uncover it (it was a large blank piece of sandstone).   probably not the smartest thing to do but this one came easy (or shall I say easier) that the many others.  I have several more pics if interested, but could only send these per page.

I'm afraid I'm seeing that too, somewhat weathered. At the most it's some kind of conglomerate, but it could just as easily be something man-made from a construction site.

I agree with the others. I think I see some mortar (the white patch by your thumb in the second picture).

What Kim said is correct.
I do not think anyone would like to prepare and use a concrete with different sort of gravel, from the smallest to the largest. A concrete of a certain quality must have a gravel of a certain type excluding gravel size below or above a  limit.
The specimen in question looks to have gravel of different dimensions, which make me think it could be natural formed, like a conglomerate, or coarse-grained sedimentary rock (considering the greenish particles).
The lamellar/bladed structure in the cropped area of your picture guides me in the direction of Boxwork/Speleothem, which might be close to a bone structure.

Was the specimen found in a karst area?

I agree with bone fragments in conglomerate.

"Thank you abyssunder and kim, and to everyone who took the time to look at my poorly posted post... I decided to picky tool and brush the heck out of it since concrete is unfruitful.   I'll send my results when I do.   Again thanks to all and to Kane who pieced together my scattered picture posts!   I can send more pics tomorrow with higher resolution tomorrow... :) "

So glad to hear it for her sake!!! :D I was afraid we might have lost another enthusiastic paleontologist wanna be. I’m one of those.

 

She had PM’ed me last night after my post on her topic. I guessed she was disheartened, but she didn’t say it. So, I empathized with her and encouraged her based on what I had surmised from her initial post comment.

 

This is the essence of what I surmised:

She had collected fossils with her dad as a kid and was in awe at the coolness of them and her dad.

This rock holds a special place in her heart and is connected with fond memories of her Dad.

Then she is told it’s “just concrete”.  

 

That would be pretty devastating to some people. It might even induce an existential crisis of sorts. It would call to question whether their dad was really as smart and cool as they thought he was when they were a kid.

She admitted I was pretty spot on with what I had surmised. 

 

I’m pretty analytical and have spent many years of my life not giving any forethought to how others are feeling or how what I say may make them feel. I’ve been trying to turn over a new leaf and learn empathy and sensitivity and think about others feelings before I speak.

 

Giving an ID on something someone found last week or yesterday is one thing. Giving an ID on something so weighty in value to someone is something that should be done with sensitivity and care. 

 

Roberta says she has crates of these things. Imagine the treasures in those crates! That’s so cool! Wish I were there to discover it all. It sounds exciting to me. Especially if they all have bone.

 

@doushantuodo you have a reference for fossils from Scotts Valley, CA? That might help educate her as to what she might have in those crates.

Kim, you are quite unique in your understanding and empathy towards others.   Thanks to you I have decided NOT to disappear from this forum, change my name and appearance, and move to another country out of concrete shame!  Feel free to post anything we discussed - I would love to have other amateurs like myself to not be discouraged - no matter what - and to remain humble.  I feel encouraged to take a deep breath and return to my crates with joy!

Great advice... I'm actually going through this site to get a better grasp on posting, posting pictures, and replies.  You are no ordinary rock , you are a true gem, and I, as many others here, I'm sure,  thank you!!

Thank you for your kind words. I am glad my encouragement and empathy helped you to have the courage to get back in there.

 

I have posted things and then felt a bit of embarrassment at my ignorance. It happens much too often for my tender spirit and ego's sake, but it keeps me humble and empathetic.  I try to take a deep breath then stop to remind myself that this is a place for learning and while I may be well educated in other matters I am not all knowing and have much to learn. I also have to tell myself that lack of knowledge on such matters is nothing to be ashamed of. It isn't like I learned it in elementary school and forgot it. My friends tell me I am way too hard on myself. So, I have to give myself credit for staying present and seeking to learn.

 

There is no shame in posting an item in the raw. I have posted a few of those in an attempt to get an idea of what it is before I go trying to take off the matrix.  I have gone to remove matrix not knowing the anatomy of what is under it and inadvertently removed some of the item never to be recovered.

 

The problem with pictures is that it is often difficult to get a true grasp of the item. It leads to us making assumptions based on what we believe we see. 

 

I remember seeing a documentary once on the Loch Ness monster or maybe some other topic, but whatever the case they showed people this picture of a tree or branch sticking out of the foggy waters of Loch Ness for a very brief moment. Many people concluded it was the Loch Ness Monster. Of course when you can look at it for a longer time you can see that it is only a tree branch. Their point was that the human mind tends to piece together the info that it sees and based on previous experience, sometime including the power of suggestion and other info the mind comes up with a final idea of the image.  I think we all do that to some degree without even realizing it.

Some deity-like properties are attributed to me:P.

Scotts Valley regional geology literature in all probability will be dominated by engineering geology/hydrology.

Any PDF will be rife with porosimeter logs,and strength profiles of Pleistocene alluvium.

Hope for Roberta's sake someone proves me totally wrong.

Have dug up some USGS stuff on that part of California,but not properly looked at them yet
