Coprolite- Looking at the spiral nature of it, I am thinking Shark. @GeschWhat

 

The photo is too small for me to see the spiral structure. If it is a spiral, it could also be a from a lungfish.

And no, this is not a 6 Leaf Clover- it is a garbage concretion.

 

If I would have found this, I would have thought it was something amazing. It really is beautiful, even if it is junk.  Mazon Creek fossil are so enigmatic.

Here you go- original size.

 

I use smaller sizes to get more pics in one post.

I can definitely see the spiral structure. Have you ever found a shark tooth or lungfish tooth plate in the concretions?

Here are two recent finds- I have my doubts on both, but they look like it. I sent the first one to a professor to look at, but I have not heard anything back as of yet.

How about one of these on the millipede?

Millipede is super cool!

Thanks!

That is a beautiful bug.

Just beautiful.

I remember that.   That was more than 10 years ago.  

 

Please come up and say hello.  I am one of the ESCONI people that are there to help.  If anyone else, comes out, please say hello.   It's good to be able to match a face with a name!

 

Cheers,
Rich

 

I will be there on Saturday as well, I hope to meet you both!

I’m starting to wonder if it is a Monura.

Could be.

How big is it?

I think the monura, such as Dasyleptus are pretty small?

I found a Dasyleptus on 7-3-18 and I was thinking about it while I was driving back from the city this evening. Here again is a pic of the one from 7-3-18, both are about the same size.

I had a family get together in Chicago this afternoon, so a couple hours before I had to leave I found enough time to open a few concretions from Pit 4. Here are the two piles that I went through and pics of some of my finds.

 

 

One thing that is different with Mazon Creek concretions is the shapes that some of them come in.

 

Here is a Dutch Shoe and Paul Bunyan's guitar pic.

 

 

Every once in a while I will come along a rock that had the shape of a concretion and later is I happen to rinse them off I discover that it is just a rock, as in the case below.

 

 

If you are hitting the concretion with the pick portion of the hammer you can also tell if it is a concretion or not. A concretion has a lower thud sound when hit and a rock has a high pitch sound- that method has never failed me when it was applied.

 

I come across a lot of concretions that have what I consider plant matter. Even though I do not keep these, I always look at them closely with a "loupe" to check for insects or spiders.

 

 

 

Here is a good example of how some fossils are orientated in the concretion- this is usually the case when it comes to many of the Lycopod or stem pieces that I find. It really makes it very difficult to get a clean break when this occurs. It this case, I would always strike this piece as the Red line indicates. I did just that and the concretion broke in half, revealing how it was set, so I then struck it along the Yellow line.

 

 

 

A couple poorly preserved Pecopteris ferns.

 

 

A Myalinella meeki Bivalve-

 

 

A couple Neuropteris-

 

 

 

A couple more pieces that appear to be Lycopod leaves- these three pieces opened in consecutive order.

 

 

A couple pieces of bark- starting with Calamites with an internode.

 

 

I usually always have a bad time with Annularia, the are either have crappy preservation or I shatter them, as was the case today. The real thing that really ticks me off is the fact that they are my favorite Mazon Creek flora.

 

 

 

 

Hopefully I will have better luck tomorrow.

I would not be able to tell even if I had it in hand.

I posted pics a short time ago of the one I found on July 3rd- it does look similar and I know the earlier one is a Dasyleptus.

@ynot and @Tidgy's Dad here is a little Chalcopyrite that I just found. Everyone in a while, I find some pretty examples in concretions.

 

 

 

Here is a yellow substance that I have never found in any concretion.

Interesting.

The second one could be yellow quartz with sulphur, (I can't see it very well) which is quite rare, but I guess is more than possible considering how the concretions form.

What do you think, Tony?

I am more inclined towards iron stained calcite.(ankerite)

Before I had to go furniture shopping with the wife, I was able to go through these concretions from the Braceville Shaft Mine (Essex Biota - Marine).

 

 

I mentioned yesterday how some concretions have different shapes, here is one shaped live a cowboy boot- unfortunately, this concretion was void of anything.

 

 

Although this pile contained a lot of concretions, there were hardly any find.

 

Essexella asherae Jellyfish-

 

 

 

Myalinella meeki Bivalves-

 

 

 

Mazonomya mazonensis Bivalves-

 

 

 

Achistrum (Sea Cucumber)-

 

 

 

After the shopping was completed, I thought I would start working on this new pile from Braceville, but as I was about to start, the storms rolled into the area again and I had to stop- maybe tomorrow.

 

 

 

 

 

 

 

 

 

 

[Innocentx]

Nice clams. I especially like the sea cucumber. However, I'm pretty sure that's Santa's boot.

[Tidgy's Dad]

The front end of the Achistrum looks great!
