Hopefully I will had better luck tomorrow.

Let's hope so. 

But some of the finds from the couple of days before that are simply stunning, particularly the Cyclus and the egg-case. 

Beautiful.

Thanks Adam and I really do like the Cyclus, it is very pretty.

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.

 

 

 

Both are very sweet!

 

Cheers,

Today I spent about 1 hour after work cracking concretions and did not find much of anything, but did find a couple cool non-fossil things.

 

Here are the non-fossil items first:

 

A concretion with what I believe is some pretty chalcopyrite.

 

 

 

Here is another concretion with pyrite- looks like 3 ghosts.

 

 

 

@ynot Tony, I am not sure if these are crystals, but they sure look like it. I put these off to the side, rather than throwing them away like I normally do. If you would like to take a look at them, let me know and I will send them your way.

 

 

 

Here is a super big concretion that I have had outside for a couple years, sometime I will get around to hitting it with a hammer.

 

 

Here are some Bivalves.

 

 

Here is a poor Essexella asherae Jellyfish

 

 

 

This may be a worm or just the way the concretion cracked open.

 

 

The only piece of flora from today Alethopteris.

 

 

Here are a couple things that I will need to look into too later.

 

 

Hopefully tomorrow I will have time to open some more.

Will be happy to take a look.

PM sent.

 

Love the color on the chalcopyrite piece.

I will also send you some of that.

That almost looks like a cladodus-type shark tooth.

Wow! I've never seen that in a Mazon nodule. Very cool.

I have found it several times in the past.

I was thinking shark tooth also when it first opened, but did not say since I am not sure.

[Nimravis]

@Peat Burns Here are some other shots of that piece.

 

 

@RCFossils what do you think?

[Innocentx]

I'm another fan of your chalcopyrite piece. Thing of beauty.

Very pretty.

 

This is probably iridescent pyrite instead of copper pyrite.The iridescence comes from an oxidized  layer. I have seen similar pyrite in concretions from the Eagle Ford Group in Midlothian, Texas. If copper pyrite were present you probably would see other copper minerals such as azurite and malachite.

This will be my shortest post of this thread. Today I opened the below, large, concretions from Pit 4 (Braidwood Biota)and found absolutely nothing.

 

 

I then opened about 45 concretions from the Braceville Shaft Mine (Essex Biota), all I found was a Myalinella bivalve and and a very small piece of bark.

 

 

Hopefully I will have better luck tomorrow and will be able to devote more time.

But the possible shark's tooth from yesterday is interesting!

@RCFossils what do you think?

 

Did you ask Jack?  What is that line next to it?  Is that Cyperites or some other plant material?

 

Cheers,

I sent it to him also, but he has not replied yet. As far as your other question, that is not fossil, it is where the two halves come together.

 

Thanks

Today I spent a few hours opening concretions that I collected from Pit 4 in May of 2003 and a bunch of smaller concretions that I collected from Pit 11 during April of 2005.

 

I will start with my favorite find of the day and it came out of Pit 4.

 

Lepidodendron aculeatum Bark

 

 

 

Mariopteris (??)

 

 

Pecopteris

 

 

Alethopteris

 

 

Bark

 

 

 

Here are some of my finds from the Pit 11 concretions.

 

 

Essexella asherae Jellyfish

 

 

Peachocaris strongi Shrimp

 

 

Shrimp Molt

 

 

Partial Shrimp (??)

 

 

 

[Nimravis]

Myalinella meeki Bivalve

 

 

Annularia radiata

 

 

Worm (??)

 

 

Unknown- I will need to look into these later.

 

 

Pit 11 concretions also contain what I believe is pyrite- they always look like UFO's.

Psychedelics were very popular in the Pennsylvanian.

@RCFossils what do you think?

This does have the General shape of a cladodont type shark but I am unaware of any having been found in the Mazon Creek Deposit.

i have found a few in some nearby black Shale exposures.

From the pictures, it appears to more likely be plant material. All of the teeth I have seen/collected have a different preservation.

Thanks for the input RC, I will put it off to the side right now.

Hopefully I am wrong and it is something more interesting

Thanks- it’s just a very long process to go through these buckets.
