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.

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

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

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!

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 entire

Good morning everybody, For anyone interested! Mid January 2019 I’ll publish a new book (in Italian, the english version is planned in 2020, but only if I'll recover the printing and translator costs) ‘Spiagge Cambriane. Meduse e tappeti algali’ [Cambrian shorelines - Jellyfish and Algal mats]. It concerns fossil jellyfish (and cnidarian in general) and their relation with algal mats, as a principal factor of the taphonomy of these soft-bodied organisms, covering fossils lagerstätten from Precambrian to the French Oligocene. The 232 pages book is rich of inedit illustrations coming from w- 19 replies
