Multi Seed Pod Branches!!!


RJB

Recommended Posts

  My youngest son found this many years ago.  When he found it,  (lifting big slabs of rock) it was very appearent that is was going to fall apart.  I picked up my little 2oz bottle of super glue and was going to glue it up so that it had a better chance of making the trip home?   Well, that didnt work so good.  I put the tip of the bottle,  ( I use those little needle tips)  where I wanted to put glue.  It wasnt comeing out so I squeezed harder.  Big mistake!  The tip popped off and the glue came out like a river!  Frigin glue everywhere!!!   Anyways, the kid was snoopin in some boxes and totes I have in one of my garages and ran into this piece again.   About 5 hours later, it came out somewhat decent?   I know most folks are gunna love this but seeing it up  close and personal I get really picky.  I still have bad memories of all the glue!   These are some kind of sycamore seed pods from the Green River Formation

 

 

This is how it came out of the tote.

Those look pretty fragile.  I'm guessing your accident with the glue may have saved them from crumbling off the matrix.  Anyway, great fossils! :wub:

This was originally classified as Sparganium antiquum, an aquatic flowering plant.  FYI: Always check Manchester! :DOH:

Manchester 2014 reclassified it Sycamore infructescences (fruiting body): Macginicarpa manchesteri  Pigg & Stockey 1991

 

A spectacular example---Congrats! happy0144.gif

"Eocene records include S. antiquum (Newberry) Berry from Wyoming, USA (Berry, 1924) and S. fushunense Geng from northeastern China (Geng, 1999).

These macrofossils bear globose heads with or without a peduncle, similar to modern-day Sparganium (Brown, 1962)."

Once again you guys post a find that has me spraying coffee all over my screen and keyboard!

 

 

Great Find!

 

This is one of the species on my too long bucket list of fossils.

Some "accident".  What a great save.  Nothing to feel badly about here IMHO.  Congrats on a great specimen.:default_clap2:

  • 2 weeks later...

A certain museum curator once told me that he would rather have a fossil covered in superglue than no fossil at all. :P

 

I understand the aggravation though. As a preparator, my eye is also drawn to the same things as yours. I have found that the Green River material responds well to a vigorous brushing with an acetone soaked toothbrush to remove unwanted glue. It will never be perfect, but you can clean it up more than you think you should be able to. Just work in small areas, repeatedly scrubbing in a circular motion and wetting with acetone often. This will soften and remove most of the glue. You will also pick up some bits of matrix that will get adhered to the glue that remains, further disguising it.

Thanks for the tip Kris but its too late.  The kid has already taken it home.
