I am glad that you like and have thought about stopping it, but I decided to continue to show members what it is like to collect Mazon Creek concretions and what you might find.

Just to let You know....

Even though I do not comment on all the additions, I greatly appreciate the show!:thumbsu:

Thanks Tony. I was just in the basement looking at what bucket I want to start tomorrow and it gets overwhelming, the amount of concretions I had collected. This week was a Stay-cation so it allowed me to put in several hours a day cracking things open. I am putting off to the side some “Perfect Shaped Concretions “, the ones collectors always wanted. I will take and try to freeze / thaw them over the winter to see if something pops open.

 

Check back tomorrow as I plan to try and spend a little time opening a hundred or so small ones that I saw- sometimes they hold some nice things.

Today was another hot day and I spent several hours going through the rest of the concretions that I collected from the Braceville Shaft Mine (Essex Fauna) during April / May 2000. I will start with my best find of the day and why Mazon Creek fossils are so great. Now this fossil is the most common polychaete worm, but being able to have a soft bodied animal is truly spectacular. Here is Didontogaster cordylina or as most collectors referred to it a "Tummy Tooth Worm". This concretion opened perfectly with one strike of my hammer, and after being cleaned up with some water, you can see its jaws (arrow) in the gut region.

 

Spectacular! :drool:

That's exactly the sort of specimen that must make all that seemingly never ending boshing worthwhile. 

Life's Good!

Nice worm!  Didonogaster cordylina, its name means 2 tooth stomach.

This might be an orbicular pinnule from a  Macroneuropteris.

You could be correct- it just looked like something that I opened a few days ago and was identified as that by Jack (Fiddlehead).

Today I spent about 1 1/2 hours going through some concretions today. Before I show the couple things that I found I will touch on a couple other things.

 

Here is the small bucket that I was going through today- they came from the Braceville Shaft Mine (Essex Biota).

 

IMG_6972.jpg.4a57abf2ed75c1127ba2c95cc728c81e.jpg

 

I mentioned in an earlier post that I was going to put aside some of the concretions that had the shape that all collectors look for. Here is an example of concretions that I removed from this bucket and try to Freeze / Thaw over the winter.

 

IMG_7014.jpg.ce4d3a959bbaeb8b3912c56e44b24b2b.jpg

 

The thing that gets really disappointing with Mazon Creek concretions is when you are striking it with the hammer and hear the nice "crack" sound, knowing that it split perfectly, but then you open it up and it is void of anything. Below are some examples of this:

 

IMG_6998.jpg.e204f58891bce00c957cc0e3fa41b94b.jpg

 

As you can see here, they split perfectly down the center- but is empty.

 

IMG_7009.jpg.02602b25ec8fe13b92e830f61929b166.jpgIMG_7008.jpg.49379e304a73a46782f47d8332ccf8b1.jpg

 

One of the things that I and some other collectors would do is collect pieces of pyrite that I believe were deposited from the retreating glaciers. As a matter of fact, I use granite glacial erratic's to place my concretions on, as a base, when I am splitting them. Below is a piece of pyrite that was in the bucket (dirty) and I thought that it was a concretion until I hit it.

 

IMG_6980.jpg.03ba73c3f21aba465a6d65e16f86e946.jpg

 

In regards to pyrite, it is also found in a lot of the concretions that you find, at least that is what I think it is. Here is a concretion that has a some in it:

 

IMG_7016.jpg.4dcb27baa049e213c857130b6b011174.jpg

 

This next type of concretion is often found, but you do not know it until you break the "crust" off. When I see these types, I do not hold my breath that the concretion will have anything inside, but sometimes I do find stuff. A whack of the hammer will soon determine what is inside. This concretion did not have anything inside:

Here are a couple finds from today, a couple things that I am not sure of.

 

Coprolite

 

A really crappy concretion had something similar inside.

Essexella asheraeJellyfish

 

IMG_6979.jpg.e65b3c4ac1aa06b3e67f0ebe041126d2.jpg

 

At first this looked like a piece of coprolite or a fish scale or bivalve, but now I think it is nothing.

 

IMG_6991.jpg.82dacb8b95ae0412a41e5af130f73503.jpg

 

This contents of this next concretion looked similar to Mazonova helmichnus (Egg cases), but I am having doubts and think it is just color differentiation. I am also including a pic of actual Mazonova helmichnus from my collection.

Today I was only able to crack concretions for 1 hour, here is the small pile that I was working on today, they all came from the Braceville Shaft Mine (Essex Biota). I did not go through all of them, but here are a couple of my finds.

 

IMG_7027.jpg.1e7d6bba5c2d579a21da3437660a409a.jpg

 

Pecopteris

@RCFossils what do you think about the ID's below?

 

 

 

Mazonomya ?? - I usually only find them in the open "Death Position", and it really does not look like one.

 

IMG_7045.jpg.e359d20ee3866be6da0384eef8e71e96.jpg

 

I was wondering if this could be a Mazonomya or possibly Sedwickia sp. due to the size.

Last but not least this piece looks like "Monurans" that I found before and was wondering if you think it is Dasyleptus??

You might be correct... just throwing out an alternative.  The various species can be tough to identify at times.  Of course, Jack is the best when it comes to identification.  I would always defer to him!

 

I'm enjoying your show!  It's very interesting.  I only use freeze/thaw and it takes a long time!

 

Cheers,

Rich

Possibly!   I have a Dasyleptus.   Mine is smaller and you can see the pointed tail.  Can you make out the legs or tail?  The segmentation looks right.  It could be a syncarid shrimp, too.

No I can not, but I’d does look similar to ther ones that I have.

After I got home from work today, I spent a little time going thru more concretions from the Braceville Shaft Mine, I have been finding a couple nice things out of these concretions from 1999.

 

It is a toss up of what was my favorite find from today, I had 2. I will start off with a very stunning Cyclus americanus.

My next favorite is a very nice Palaeoxyris.

Lastly, today as with almost everyday, I come across concretions with pyrite or crystal inclusions. Here are a couple of examples and you can see why some people think that they found a fossil in their concretion.

On the first 2, I do not see why You say they are not fossils.

The first one is clearly a pig scratching its behind on a rock, and the other is clearly a swan!!:rofl::rofl:

 

I wouldn't call the other piece  "crystal". (does not have the shape.) It looks a lot like opalite, which is not even considered a mineral.

 

As for the Cyclus americanus and the Palaeoxyris, WOW!!!!:faint::faint: Those are stunning!:yay-smiley-1:

You would know better than me if it is a crystal or not, they just look like it to me.

Thanks.

 

A crystal has a defined geometric shape. Crystaline is "crystal(s)" that had no room to form a shape.

Things like opal and obsidian are considered mineraloids, and put in a separate clade.

Today I only had enough time to open about 60 concretions from the Braceville Shaft Mine. Here are the finds from today-

 

Essexella asherae

A couple small concretions that have no fossil but do have an inclusion of pyrite.

Many concretions shatter once you hit them with a hammer- this no fossils are found.

Hopefully I will had better luck tomorrow.
