Hi folks, I went to the spoils pile with ESCONI pre-covid. I've had a bucket sitting out back ever since with concretions. Went through it today and banged a few together. I am not good at recognizing Mazon material, so I thought I would ask for some assistance here. I'm 99% sure 1A is a jellyfish, I haven't sorted out the name yet though. 1B appears to have some whiskers or antennae, so I'm hopeful it's some sort of shrimp or creepy crawly. The rest I'm kind of at a loss on. Any help appreciated!

I have a lot of unopened Mazon Creek concretions and though I do put some out in the winter for the Freeze / Thaw process, the vast majority, especially the larger ones do not open. So to dwindle my concretions, I have no problem whacking them with a hammer, and that is what I was doing today. As we all know, this is not the best way to do it since it can damage a nice specimen, but I take my chances. I always picked up any concretion that looked promising and never passed up larger ones. This all depends on the are that you are collecting, concretions from Pit 11 are never super

Hi! I’ve been working on opening some nodules from Mazon Creek, IL, and opened this one about an hour ago. I’ve been looking at pictures online of jellyfish and have seen some loosely defined like this nodule, though this is probably just a regular old concretion. What do you think? Thanks! P.S. In hindsight I realize that wetting this nodule down wasn’t particularly helpful lol

A rangeomorph holdfast trace fossil from the Ediacara formation, Rawnsley quartzite of the Flinders Range, South Australia. This specimen is Medusina mawsoni, so called because it was until recently thought to be a jellyfish, but is now believed to be the attachment point of a fractal rangeomorph as Charniodiscus is the point of anchorage for Charnia sp. This one may have been the holdfast point for some species of Rangea. The diameter of the outer circle is 1.5 cm and the fossil is estimated to be 555 million years old.

Moroccan Jellyfish Fossil?
Rikache posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hi there! I was browsing through my favorite sellers' stores earlier today and I came across this very peculiar fossil. The fossil is said to be of an Ordovician age jellyfish (Eldonia Berbera) from Mecissi, Morocco. I'm still fairly new to collecting fossils, thoroughly researching them, and learning about paleontology more in depth, so the thought of a jellyfish fossilizing never really crossed my mind. I'm not entirely interested in purchasing this fossil; rather, I'm posting this more out of pure curiosity. I'd greatly appreciate it if anyone could share their insight about thi -

The diameter of the dark colored depression is about 1.5 cm. Around this depression there are only very faintly indicated ring-shaped structures with a diameter of about 4 cm. On the slab there is another smaller impression of a second medusa. The Krukowski Quarry near Mosinee, Wisconsin is well known for abundant ichnofossil impressions of Climactichnites and Protichnites together with hundreds of beached jellyfish. Jellyfish impressions up to 70 cm in diameter were found on several bedding layers, so far the largest jellyfish in the fossil record. The largest recent form, the lion's ma

Hi guys! Please assist to identify if this is a Jellyfish strobila fossil . I was expecting it to be a plant, but the shape of the disks is so different. N.1 N.2 N.3 N.4

Hello everyone! I've been inspired by so many good Mazon Creek topics in this forum, I thought I would start my own. I'll post my own finds, which so far don't include anything as exotic as a Tully Monster, but maybe I'll get lucky on page 134 or so... I have to credit my kids with getting me interested in fossil collecting. I was always interested in rocks and fossils but when my 10 year old son had his dinosaur phase it really sparked my interest again. I wondered if an ordinary person like me could go out and find fossils? So I Googled fossil collecting and found out that not on

Just wanting to confirm that this is a jellyfish.

Location: Mazon Creek (Illinois) I think some or all of these may be jellyfish, but I'd like to defer to others. If they are not jellyfish, what are they? The last two photos are both sides of the same pieces. There appears to be something on both sides. Thank you for your time.

Hi everyone, its been a while since I posted here so wanted to share some of my favorite finds from the past few months. Ive mainly been hunting in the marine Blackhall Limestone at various sites across the Midland Valley of Scotland. Although there are several fossiliferous marine limestone and shale bands of similar age and depositional environment in the Midland Valley, the Blackhall seems to be by far the most productive and also tends to have the best preservation. Ive mainly been looking for chondrichthyan teeth, crinoid cups and jellyfish so I'll post these first, I have had a few nice

Hi All, Recently I purchased some Shale from U-Dig, UT. The trilobites inside were super swell, but one of the more interesting finds was this...thing... It appears to be a circular mass, with some veins or something radiating from the center. My hopeful brain began to think it could be a jellyfish, though realistically it is highly unlikely, and I've never heard of anything like that being preserved in the shale from U-dig. Any help or suggestions would be greatly appreciated, as I am at an ABSOLUTE loss. Thanks, -Snag

I headed out to Mazon Creek IL a few days ago and came back with some fair nodules. I found a big nodule(6) and used the freeze thaw method to open it, I think it might be a jellyfish but I’m unsure, as I guess it could be nothing. 1 and 2 just have irregular shapes and I believe are made of pyrite. 3,4 and 5 are nodules that did not open from freeze thaw so I broke them with a hammer, and they have some white marks but I’m not sure if they are anything at all. Help with any of these finds would be awesome, and I had quite the adventure at Mazon as it rained and was quite filled with ticks!

Got out to one of my favourite Blackhall Limestone sites in the Midland Valley of scotland for the first time in a while last week and made a few finds I was really pleased with. Found my smallest jellyfish so far at 25mm across (I'm told examples as small as 8mm have been found), a well preserved example of a Penniretepora sp. bryozoan for this site (thanks @TqB for the ID! ) and also a couple of teeth that still need some prep. A few months back at the same site I got another nice example of a Poecilodus jonesi posterior tooth plate that I never got round to posting here so here it is too, i

Hello everyone! I’m looking for any information on conulariids while showing the one I found! I found this specimen in west Michigan while fossil hunting recently. I used my microscope to get very zoomed in details of the ridges as this conulariid is very well preserved. The two very close up pictures are a 1000X while the last picture that isn’t as zoomed in is 50X, both are the same spot of the specimen. I know that these are thought to be some type of jellyfish/coral but that’s all I know of these fossils. Any more information would be really awesome, and I hope that you enjoy this find!

Found this odd concretion possibly a jellyfish. It was at washburne state park on oregon coast. It was in the sand mostly exposed thought it was trash at first a Frisbee or piece of styrofoam. But it's definitely stone, and was a week or two after our beaches were covered in a wash of jellyfish. No room to step between them even in most spots. This was found in the sand all the way at the back of the beach near the end of the sand that then hits the dune area and cliffs. I am wondering if it is of a jellyfish, maybe one that washed back further and stuck while the rest got swept back out?

Merry Christmas folks. Just wanted to share some photos of one of my favorite specimens.. It's a 3D mold of a Scyphozoa conostichus jellyfish from the Pennsylvanian period from the Nellie Bly Formation, Sand springs, Tulsa, Oklahoma. It's 5.3 x 4.5 x 4.0cm.

Hey guys! I’ve got some items here from Mazon Creek, IL, and I need a little help IDing them. The first one looks like a jellyfish to me, but I’m no expert. The second two... honestly I don’t even know if they’re fossils at all. The last one makes me think it might be because the center of the inside is dark and glossy and looks a little like a crunches up jelly, but I really can’t say. Any thoughts?

Hello again. I have several of these strange fossil discs. I cannot find tags for them in the boxes of minerals and fossils recently acquired. Possibly some sort of jellyfish? sea sponge? Any help with ID is of course always appreciated!
