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 finds of other invertebrate groups recently though so I'll get some pics of these shortly. First up, the jellyfish. This is the largest Ive found so far at 80mm across. Another larger specimen at 60mm across. An average sized one at 32mm. And one of the smallest so far at 21mm.

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, its 12mm across.

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!

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 only could I search on my own, one of the world's best sites for amateurs was just 3 hours away! The date I discovered Mazon Creek existed was 9/10/2017. I know that date because earlier in the day was the last ESCONI trip to the Braceville spoil pile for the year - I just missed it! So in May 2018 I finally went on that trip and was hooked. Since then I've gone to Braceville several times, the I&M Canal trip once, and a handful of trips on my own into Pit 11. I want to thank too many people to list for helping me learn about this new hobby. Everyone I've met on the field trips has been so friendly and helpful. And if you have posted something about Mazon Creek on this forum, I've read it. Special thanks to Nimravis for his Sometimes You Have To Whack It thread, which he started the day after my first trip to Mazon Creek - it has taught me so much and I'm so impressed at what a genuinely nice person he is. And Andrew Bach's book from his American Fossil Hunt site is wonderful, so so helpful. With that, onto the fossils (and lots of questions from me). I thought to start I would show some of my jellyfish, all Essexella asherae, I believe. I find it interesting that they are all so different, although they tend to fall into various "types" - some have a distinct "head", others are just faint outlines, some are just cylindrical shapes. #1-3 below are all from Pit 11 - the first two have a distinct head and the other is more cylindrical. For anyone who hasn't heard of Mazon Creek, these fossils are found in siderite concretions from the mid-Pennsylvanian epoch of the Carboniferous period, from roughly 305-310 mya. Cheers! Chris

Day Two ; Locality Two (or Seven if you include Day One) Prepping and Retail, Erfoud, Morocco. 20th February 2019 Erfoud town itself is famous for its beautiful fossils, its skilled fossil preppers and also for its wide variety of fakes, composites, good and bad repair jobs and utter frankenfossils. A large percentage of fossils from Morocco that are available in shops and on the internet the world over originate from here or pass through the place. Fossils are sent here for prepping from all over the south and then sent from here everywhere in the country and abroad. There are many little shops, prepping centres with huge attached shops and 'museums which are really pretty much just shops as well. Top Tip :The prices here are about ten times the price of the prices in the little shacks on the edge of town or elsewhere in Morocco, but haggling can reduce the cost significantly. Many places have 'fixed' prices, but they're actually always negotiable. This time, we went to the one my friend Anouar, who is a tour guide, takes his tourists and I was asked politely not to accuse the owners and chap who'd show us around and do the chat, of having fakes or wrong info, so i had to bite my lip. We asked if it was okay to take photos and they said yes, which I was surprised about, but I guess it was because Anouar was going to use photos for his own purposes and this would involve advertising the shop. Top Tip : You will see a lot of fixed prices in Moroccan Dirham in the pieces and shelves. Divide by ten to have a price in US dollars. Because we were with Anouar, we were told everything is 50% of the marked price, but I suspect they often do this anyway, "Special Berber prices, today only". I've heard that before. And you can still haggle to get something way under that 50% and you just know they'll still be making a good profit. I didn't buy anything. Little local stores are more my line anyway - I rarely shop in supermarkets. Here is the entrance where you can see huge plates ready for prepping and polishing, some have been cut into pieces and they glued back together it seems to me, I know this happens with the crinoid beds, so i guess it's true of the orthocerid and goniatite stuff too. Some just look cobbled together because of the circular saw marks when cutting out upper layers.With these, polishing will remove the grid lines. These sheets are from the local area and contain the goniatites and orthoconic nautiloids we were walking on earlier, but from a better quality, less eroded and distorted source. Famennian, Upper Devonian, I think. This photo shows one of the trenches they dig to reach the best quality material, similar to the ones i was walking along earlier this day : Below, somebody walking on the slabs and some maps of the the world at different times in it's past, showing continental drift. : Notice these are not the famous black orthocerid marbles that come from elsewhere. The picture of Spinosaurus is a bit misleading, as you all know, it's not found in these marbles or in the Erfoud area. In fact there is very little Kem Kem material available here these days, though there was in the past. I suspect the Kem Kem area probably has it's own facillities nowadays.

On this plate is a Keichousaurus and an unknown fossil. You can see there is something at the left hand corner, does it look like a jellyfish?

As with so many fossils from the Ediacaran, it is not certain to which phylum they belong. According to Fossilworks, Cyclomedusa belongs to Cnidaria. From Wikipedia: "Cyclomedusa was originally thought to be a jellyfish but some specimens seem to be distorted to accommodate adjacent specimens on the substrate, apparently indicating a benthic (bottom-dwelling) creature. The markings do not match the musculature pattern of modern jellyfish. The fossils have been conjectured to represent a holdfast for some stalked form — possibly an octacorallian, or something else entirely."

think i had put this on here before but the pics were bad and it was with a group... took a few new pics and found a similar item posted way back in 2014 I think also in texas... could this be a similar item? but in perhaps poorer condition. this is the post:.....

Hello to all, I just ran across this site, look forward to chatting with others on finding, preserving pieces of our history. I've been collecting fossils from my local areas for over five years, and have donated many of my finds to our coal mining museum in our little town. We grew up playing on the slag piles of strip mines and deep mines and use to throw them rocks all over, little did we know what was inside those precious gems were fossils. I find numerous types of fauna and floral specimens and normally I give them to others to put in museums or historic places...Truly enjoy collecting fossils and our area is rich in these gems... I'm amazed every time I open up an fossil and be the first set of eyes on the amazing find. My bucket list is a Tully monster and someday will find one... So happy there are others that thrive on finding fossils and not just rocks...Thank you..

Supposed to be from the Cretaceous, found in Mota del Cuevo (Spain). I think it may be a jellyfish... on a shell... Note the soft-looking round brownish double structure on the center. Between the two structures it looks transparent white. Underneath there is a shell. On top there is a stick-structure with another round structure of a different kind I think. What is it? Thank you!

Hello from Spain! I just signed up! I am not an expert but I am willing to learn more about fossils. I have recently found some specimens in the Castilla-La Mancha region (Spain) that I would love to identify. I am afraid I have already checked in a local forum but these specimens may not be that common since no one was able to identify them. I hope I will be lucky in this forum, I cross my fingers! I will start by posting one ID question regarding a specimen recently found in Mota del Cuevo (Cuenca) that, according to the acedemic texts I was able to find, shoud be from the Cretaceous Period. I think it may be a jellyfish on a shell of some kind... By that way, I am sorry if my English is a bit rusty sometimes! Thank you!

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 large, but Pit 4 always produced larger ones - see below. Though these are large, they are by no means my largest. The vast majority of the time there is nothing inside, like the one below. Other ones produce something nice, like this Alethopteris that I cracked open today. Cleaned up_ A couple of my other finds from today, nothing spectacular, but is nice to get rid of the dud ones.

I discovered this specimen by chance a few years before I got into fossil hunting. I was on a vacation at Oak Island, North Carolina when I found it. I am thinking it is a Jellyfish fossil.

Unfortunately I don’t have much useful detail to share with you here. I found this in Illinois at the bottom of a bridge filled with slabs of rock blasted from God-knows-what quarry. It other slabs like it contained fragments of brachiopod shells and calymene trilobites. It is about 4 1/2cm in diameter. My best guess was a jellyfish or something similar; a geologist whom I showed it to agreed, but honestly neither of us were at all confident in our assessment. Thoughts?

Probably Essexella asherae, but wishing it were Lascoa Mesostaurata.

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.

Hello, I was thinking of taking my kids to Purse State Park in Maryland in the coming week while the weather is still this warm, but I have not been there before and was wondering if jellyfish are as much of an issue when the water is warm as is the case in the Chesapeake Bay and places like Brownies Beach. I know very little about the Potomac and the water type and whether it is brackish enough to support jellyfish, hence my question :) Last thing I want is for a family outing looking for shark teeth to go south due to some floating menaces. Looking forward to getting to this location and sharing the finds with the forum. Thanks, Matt
