Hello. I am looking for some help identifying this fossil. Here are some pertinent details. Thanks in advance! Size.... It is about 42mm long by 21mm wide. It is a full fossil on the surface of a mostly spherical rock that is just slightly bigger than the fossil itself. Shape... Oblong. Oval. Color... The rock is a brown color. The fossil is white. The rock appears to have a lot of minerals in it. I can see glints of very small crystals throughout the fossil. Texture... Very rough. The organism appears to have had body segments. The deepest parts of the fossil appear to be about 1mm deep in the rock. Distinctive features... This is what is baffling me. It appears to have a "tail" with fine segments like a fish, however it seems to be horizontally oriented and not vertically like a fish. (Tail is in quotes because I am not sure it really is a tail per se.) It looks like it may have had appendages that were concentrated toward the center length of the body. The "head" appears to be articulated, as it is slightly tilted to one side. While it has a head, there are no distinguishing features visible on it. Now for the really weird part... The entire organism, including the head, is surrounded by hairs or feelers or some kind of structure. It appears to be very similar to the tail segments. I can see very clear individual elements of this structure. The rock also has several other smaller fossils on it that look to me like very very large plant cells group together in pairs to form longer strands. I believe there is also a tiny shrimp-like fossil on the rock (also pictured below). Geological Context... It is on a fairly spherical rock that was found on a Lake Erie beach. That beach was located at Vermilion, Ohio. It was found amongst a lot of rocks of similar size and quite a bit of shale.

Cleveland Museum of Natural History Expansion
JurassicParkCarnotaurus posted a topic in A Trip to the Museum
I recently went for a visit to the Cleveland Museum of Natural History (after a great Indians game) and thought I would share with you the renovations that are going on right now. As a Cleveland native, it is very exiting to see the museum grow and it will certainly be great when completed. It is getting ever closer since its announcement- the Perkins Wildlife Center has been complete for some time. Hopefully some of you will get the chance to come visit when complete, its truly a great museum! https://www.cleveland.com/architecture/index.ssf/2015/02/first_look_cleveland_museum_of.html -

Hello everyone! My name is Scott Jankowski, 23yo, and I live in Fairview Park, OH. I stumbled on this forum when I was researching Ohio geology (what can I say, I like rocks~) and really liked it! I am an outdoorsy type of guy and fossiling has become one of my newer hobbies. I like weather and water, and anything that walks, crawls, swims, squirms, wriggles, digs and flies on, over and under this amazing world we live in. I am also an avid Go player, and always interested in meeting new people (especially people who are interested in as many (odd??) things as I am!) I'm hoping to learn a lot, and make new friends. If there is anyone near the Cleveland area, I'd love to chat! Nice to meet you all, Scott http://senseis.xmp.net/?ScottJankowski
