Dinosaur bone?


Artv

Recommended Posts

Hello all, 

 

Recently on a trip to Alberta I received this in a museum.  It was labelled as a dinosaur bone, but not further information.  Would anyone be able to provide a clearer picture?  Thanks!

We could try and provide a clearer picture of what you have, but you will need to provide better pictures for us.

 

All I can see in your one provided picture is what appears to be a thick coating on the specimen and glare from the glass table. I THINK that I can see bone texture if I zoom in (top middle).  :unsure:

Hello again, 

 

Sorry for the poor quality picture.  The piece was wet, not thickly coated.  

 

I'm attaching three other pictures, with a pencil included for size reference; two of the 'front' and one of the 'back'.

You might compare with vertebrae belonging to Champsosaurs...not quite dinosaurs but still pretty neat creatures.

Hello again, 

 

Thanks for the answers.  I have two more questions.  

 

1. I have another piece; three pictures attached with pencil for size reference.  One side appears to have a bit of bone fragment in the center, but the same fragment is not visible on the other side; rather, it has a very different appearance.  Any ideas? 

2. For preservation / coating.  Some websites suggest applying several coats of a 50/50 mixture of white Elmers glue and water.  Others suggest clear coat (varnish?).  What are your suggestions? fossil4.thumb.jpg.80bfbc1d931eed2e1b092396caeca9d7.jpg

Might be turtle.  I don't recommend using either to stabilize your bones.  Consolidants like Paraloid B72, Vinac (PVA), Butvar B76 are are a much better choice and most are available online. A 50 /50 ratio with acetone is a good start.

Agreed with Troodon, Butvar and Paraloid are a palaeontologist's best friend - and they can be removed by washing in acetone again.

I really we could delete that garbage from every website that still lists it.  Glue and varnish were the consolidates of choice 100+ years ago.   As Troodon posted, there are much better choices available today.  Those old methods will lead to yellowing, cracking, shrinking, failing, and they are mostly permanent.

I'm having trouble finding Paraloid B72 and Butvar B76 online from anywhere in the U.S.  I've found a few international sellers, but they mention possible extra fees to export it (but not the cost of the fees).

My favorite things about fossil hunting: getting out of my own head, getting into nature and, if I’m lucky, finding some cool souvenirs.

Thank you, that was the only place I'd seen it, but you have to buy a minimum of a pound. Based on the fact that I only have some shark teeth to do (and I believe I only need to do the root if the enamel is still intact on the crown, right?), I'm guessing that will last me forever.  Or maybe not...brand new to this.

Kremer pigments appears to have paraloid  B-72 in stock. https://shop.kremerpigments.com/us/shop/mediums-binders-glues/67400-paraloid-b-72.html

Thank you! I see that they have smaller quantities, which is probably what I will start with.  Etsy has B-90, but I don't know the difference.

 

Thank you both!

Not familiar with B90 but would not recommend it if others are available.   I've never used consilidants on shark teeth unless their are problem with the tooth.
