From the album: Missouri Conulariids
Another broken specimen weathered from the rock. I always find these jellyfish fascinating whenever they present themselves. -
From the album: Missouri Conulariids
A lot of my conulariid finds tend to be broken at or near the tip of the apex, even before the attachment which is typical of other conulariid specimens. I am not sure if it is a plane of weakness, a common feature when the animal dies, or simple predation, but when I collected this specimen from the Paola limestone the lower half was missing from the rest of the slab, despite being an almost clean fracture. -
My boldest claim yet, Is this a small Chunk of Listracanthus? or Bias? ( Missouri )
Samurai posted a topic in Fossil ID
Location: Missouri Period: Pennsylvanian Formation: Iola Formation (Muncie Creek Shale Member) Hello! once again. Today I have what is either a cluster of scales, or a possible chunk of listracanthus that was entombed in one of these many phosphate nodules I have come to possess over the years. I only say Listracanthus due to the "scales" looking feathery and wavy much like the 3 other Listracanthus denticles I have found so far from these nodules. The main difference is that it appears to be attached to something this time. Let me know what you think! Rotated: Ever since I heard of the tragic tale of Listracanthus I have always been fascinated by it. Which is why I am afraid I might be a little too biased in this assumption. Other Half of the nodule: Size: In the surrounding Limestone matrix, there is also a very small brachiopod that my professor couldn't nail down the exact species of. Thought he deserved his little section too! Lastly here are a few pictures of other denticles I have found from the Muncie Creek Thanks for reading through all of this and let me know what you guys think, I'm not even sure what part of the body this would belong on the animal itself, so I would love any information.

ID help. Crustacean, mollusk, or something else? Upper carboniferous.
Gramps posted a topic in Fossil ID
I have found several of these in an outcropping of shale and limestone in the Iola Formation in Northeastern Oklahoma (middle Pennsylvanian). The longest dimension is about 15 mm (≈ 5/8 inch). Some of the other specimens are slightly larger, but all have the same pattern of bumps. (I photographed this one because it shows the least wear.) I’m wondering it might be the carapace of a phyllocarid or some other crustacean. Alternatively, it might be a bivalve or other mollusk. Any help with ID would be appreciated. Focus and exposure were difficult, so there are several images. Best wishes.
