dudeman Posted January 7, 2012 Share Posted January 7, 2012 Hello Everyone, I want to see everybodys Jellies! I have 2 small ones (that I am very happy to have ), both from Mazon Creek. I know these guys are hard to photo :pic: sometimes (at least for me ), but please show us yours if you can... Troy Nelson Link to comment Share on other sites More sharing options...
Wrangellian Posted January 7, 2012 Share Posted January 7, 2012 Oo, this should be a fun thread. I've got a few from Mazon also but not sure if it will be worth posting considering my photo skills and that most everyone else's will be from the same place. (I know there are other places for jellies too, hope to see some) Link to comment Share on other sites More sharing options...

RCFossils Posted January 7, 2012 Share Posted January 7, 2012 (edited) There are five described Jellyfish that can be found in the Mazon Creek deposit. The most common is the highly variable Esexella asherae. Essexella is by far the most common animal found in the Essex assemblage of the Mazon creek deposit. Although they are all considered to be one species (I have my doubts) there can be significant differences in appearance.

RCFossils Posted January 7, 2012 Share Posted January 7, 2012 The second type of jellyfish is Octomedusa pieckorum. These are more scarce and finding ones with the tentacles is quite rare. Link to comment Share on other sites More sharing options...

Wrangellian Posted January 19, 2012 Share Posted January 19, 2012 I was right, fascinating topic! Very nice variety, RCF, I had no idea how much diversity there was at Mazon, tho I knew the Essexellas varied quite a bit, but interesting that these could be different species. I have a few examples of the one that looks like a 'male member', but now I have to keep an eye out for the other types. That is indeed a fantastic box jelly!! (I know I won't find one of them) BTW are you able to shrink your pics down to about 900px wide so they dont take too long for my hamster-wheel connection to download? Here is my example of Eldonia berbera from Ordovician (Rawtheyan/Ashgillian/U. Katian) Ktaoua Fm of Mecissi, Morocco, said to be youngest example of Ediacaran-style preservation. I dont know if this counts in this category but what other category should I put it in? (The Burgess Shale Eldonia was originally thought to be one by C.D. Walcott) I'll include my attempt at a stereo photo for those of you who can view these, see what you think. I reversed the left/right images so it can be viewed by crossing the eyes. I could include the other version if there is interest in it. Just dont view it too long, it'll give you a headache! Link to comment Share on other sites More sharing options...
