Mazon Creek Collection- Purchased

[Nimravis]

Here are a few of the jawless fish, Gilpicthys greenei.

 

 

 

 

I believe that this is a Gilpichthys, but is does look a little like a Esconichthys apopyris.

 

 

 

Here is a beautiful Kellibrooksia macrogaster.

 

 

 

 

And here is a large one.

 

 

 

 

 

Macroneuropteris scheuchzerii-

 

 

 

Calamites with 2 internodes-

Did you need a second mortgage to acquire this collection?

Here are a couple from tonight-

…

 

 

 

 

 

 

 

Reticulomedusa greenei-

 

 

 

 

I am thinking that this is a portion of Myriacantherprstes sp.-

 

 

 

 

That Reticulomedusa is really interesting, I don’t believe I have ever seen one with the tentacles preserved like that.

 

I think the second specimen above is actually a partial Mamayocaris jaskowskii lobster.

 

Keep ‘em coming, this collection is still blowing my mind!

Funny you say that, Bob and I discussed the same thing on that piece and I thought it was to large and I thought that I saw some legs at the end of the larger piece and that is why I was thinking millipede.

Ben- I agree with you.

[Nimravis]

Here are a couple from today-

 

Palaeoxyris appendiculatum

 

The larger one looks odd, but I think they are the save.

 

 

 

 

 

Tullimonstrum gregarium- Tully Monster

 

 

 

 

Annularia radiata-

 

 

 

Pecopteris-

A baby Tully Monster-

 

 

A couple more Tullies.

 

 

 

 

 

 

 

Here are a few miscellaneous shrimp.

The two you have labeled A. inflata are A. radiata. The latter tends to be smaller in size and have around a dozen leaves, while the former tends to have two dozen or so.

Thanks- I would not have thought that, I will change it now.

Add me to the chorus of praise, Ralph. Stupendous collection! It's all wonderful but I'm always impressed most by the soft-bodied things - jellyfish, worms, etc, particularly the rare ones though the exceptional examples of common things are also impressive. No wonder Mazon is so famous. Never seen so many Tullies in one place. I wish I had just one that had the grasper and better eyebar than the example I have. That guy must have spent a lot of time at that site, even for the old days when the collecting was easier. Think of what all he tossed or gave away...

Thanks- it seems like he did not really pick up Essexella’s, at least that I can tell from the concretions that I have gone through to date, there are a few examples of some real nice ones in the collection, but not the amount that you would expect, but that could change as I take rubber bands off of concretions. The same can be said for coprolite, I don’t think I have come across any so far. Both of these fossils you would expect to find a lot of while collecting at Pit 11, the only reason for the lack of them is that he may  given them to Walter. We would always give fossils to Walter so he could make “Fossil Grab Bags” that he would take to the Wilmington Historical Society so they could sell and make money for a renovation of the building. We also used the Grab Bags to give away to people at the Fossil Collecting trips that we would do for the Braidwood Library. Wham Walter passed away, he wife asked me to get rid of some of the Essexella’s that she had and I sold about 500 of them to a dealer I knew at one of the local shows. I will have to ask Bob the next time I talk to him.

I have run out of superlatives.

As always, amazing!  This one seems to be looking out at world from 307 million years ago...

Still going with your amazing stuff! Thank you for taking the time to show them! I remember buying a fair amount of mazon ferns for my shop and when I saw my first Macroneuropteris scheuchzerii- I thought hello, I have only gone an bagged me a Dinosaur feather!

Rich that is funny that you say that, the below concretion is what got me into MC collecting. A friend of my wife’s gave it to me because she knew I liked rocks and fossils. She got it from her sister, who went on a field trip with Northeastern Illinois University, they went out to the Braidwood area to collect fossils. When she gave me this rock, she told me that if I hit it with a hammer there might be something inside, which I did and found the below Fossil. I like you thought it was something else, I believe that it was a fossilized bone and it was not until I met Walter and his wife, Rita, that I learned it was a Neuropteris  leaf- then my life changed. Lol

 

 

As far as this thread goes, I am only posting pictures of a small amount of fossils, I have so many that I have not seen yet. It is taking time due to the process that I am following.

[Nimravis]

Here are a couple pieces from yesterday that I showed in the Fossil ID section. Thanks @RCFossils and @connorp for the ID’s.

 

Caulopteris branch scar-

 

 

 

Mariopteris nervosa-

 

 

 

 

A poorly preserved Dryptoscolex mattiesae worm.

Nice story!   It does resemble a bone.  I like how many Mazon fossils have 3-d relef.

Here are a couple more “Blades”, Esconichthys apopyris.

 

 

 

 

 

 

 

Lately I have been second guessing myself on ID’s and like the worms, the shrimp look similar and them there are name changes that have occurred. I believe that this is a Lobetelson mclaughlinae.

 

 

 

I few you want to shot some ID’s on the next couple of shrimp, feel free.

 

 

This would have been a big boy.

Good, it sounds like they went to good uses. I guess you can only keep so many of the common things like Essexella, even when you love them like you and I and many others here do.

My hunch is you will not open many Essexellas except for a few that have something unusual about them like that one with tentacles...

[Nimravis]

Here is another cool piece, it kind of looks a bit like an Essexella asherae, but I think it might be a Anthracomedusa turnbulli. What do you think? @RCFossils @deutscheben @Mark Kmiecik @connorp @stats

 

 

 

I am thinking this is a Rhacophyllum clarkii.

 

 

 

 

This one has me stumped, it kind of looks like a pill millipede and then I was thinking a Cryptocaris hootchi, and then Kottixerxes glorious and then I am like it is none of those. Any help would be appreciated.

That jellyfish, hoo boy, I can’t say I have seen anything that looks like it in the literature. That might be an entirely new genus/species.

my best guess is Lascoa mesostaurata .

I think the arthropod is likely an example of Cryptocaris.

More amazing material!

[stats]

That jelly is something else.  I've never seen one like that.  Maybe Anthracomedusa from a different perspective?  The Richardson's Guide has an Octomedusa drawing that looks similar.

Rich

I haven't heard of Lascoa mesostaurata.  The Richardson's Guide says it was described from a single specimen from Astoria.
