Its fossil Friday, so share a pic of your latest fossil acquisition, or prep.

 

This is my latest prep project, a large Mioplosus from the Green River fm of Wyoming.  Its not 100% finished but getting very close.  Sadly it had already lost 1/2 to 2/3 of the tail before I found it, it has some damage to the rear dorsal fin, and the original break/exposure was through the head so it will take extra work to remove the glue used for an improvised field repair.  I did learn a good lesson and will be bring proper consolidates and glues when I go fishing this year.

Beautiful fish and prep. I brought 5% and 20% B-72 solution in 15ml nail polish bottles with me the last time I was at the fish quarries. Nail polish bottles are great because they already have a brush in the cap, which helps with application and are already designed to hold a volatile acetone based solution. I used the 5% solution for consolidation and 20% as an adhesive. It seemed to work fairly well. 

 

This is a Cryptolithus tessalatus (Green, 1832) cephalon I obtained in a trade with @historianmichael that I prepped this week. This was the first time I've ever worked on material from that locality. I was doing well on the left lateral border, but apparently the right side was too thin and I destroyed part of the right lateral border. I guess that's a learning experience and shows you that not all of us get it right the first time.

I keep a roughly 5% solution in nail polish bottles in my prep shack.  I didnt start using those until last year, after I had already been to the fish quarry, but they and bigger ones are definitely going with me this year.

It is well past Fossil Friday but here are a few things I found on a recent trip to the Lance Fm (late Cretceous).  There is small dromaeosaur tooth and a stereophoto of a mysterious little reptile vertebra.  The scale bars are my wife's finger print, and mm for the vert.  (I thought I posted these a few days ago, but they seem to be either somewhere else or I failed to post. )

Wow, those are tiny finds!

I actually finished this up a few days ago but here it is again.  This is a ray from Lebanon.  98 million years old.  Here are before and after pics.  Had to do some major repair on cracks and bad rock.

@RJB thats a great fossil, and it reminds of pics of a recently discovered fat-tailed ray found in the Green River fm.  Those shrimps are incredible too!

Hi RJB,

 

That is a guitarfish, which is a ray as you said, and I think it's one of the rarer animals from the layer.  It may be the genus, Rhinobatos.  With the shrimp, it's a great association piece.
