Slaugbr1 Posted November 22, 2017 Share Posted November 22, 2017 5 day straight out in ohio. Getting better at pinpointing where to look! Pick up a rock and thought maybe a fern but i think i see a little tail spike maybe. Is this a Trilobite? And if it is should i try and clean it up at all or leave it?

Ludwigia Posted November 22, 2017 Share Posted November 22, 2017 Certainly looks like one at first glance. If you don't have any proper prep instruments, it might be hard to clean up.

Fossildude19 Posted November 22, 2017 Share Posted November 22, 2017 Size of the item? Where in Ohio? Can we get photos of it dry?

Slaugbr1 Posted November 22, 2017 Author Share Posted November 22, 2017 The reason i thought it was its covered in matrix but if u look at the bottem of the photo u can see the tail areas 2 spikes coming out Link to comment Share on other sites More sharing options...
westcoast Posted November 22, 2017 Share Posted November 22, 2017 I'm a bit more convinced now as I can see what may be pleural furrows on the sides however the lack of definition of the middle lobe is odd. Could be just a stage preservation. Others here will be abe to give better answer. Link to comment Share on other sites More sharing options...
Tidgy's Dad Posted November 22, 2017 Share Posted November 22, 2017 It could well be an arthropod of some kind, but the body doesn't show either the cephalon, thorax and pygidium or central axis with two side sections (pleura) diagnostic of trilobite Hence a suggestion of eurypterid as we try to think what else it could be. Do we know the age of the rock? Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...
Miocene_Mason Posted November 22, 2017 Share Posted November 22, 2017 Looks like a conulariid. 2 “...whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been and are being evolved.” ~ Charles Darwin Happy hunting, Mason Link to comment Share on other sites More sharing options...
PFOOLEY Posted November 22, 2017 Share Posted November 22, 2017 Maybe a plant?...like Calamites? "I am glad I shall never be young without wild country to be young in.

Miocene_Mason Posted November 22, 2017 Share Posted November 22, 2017 This is a Conulariid. 4 “...whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been and are being evolved.” ~ Charles Darwin Happy hunting, Mason Link to comment Share on other sites More sharing options...

Slaugbr1 Posted November 22, 2017 Author Share Posted November 22, 2017 conulariid seems to be it. Link to comment Share on other sites More sharing options...
Douvilleiceras Posted November 22, 2017 Share Posted November 22, 2017 If your area is Carboniferous, it's surely not a trilobite. The form doesn't match any Proetida that survived the Famennian extinction. 1 Regards, Jason "Trilobites survived for a total of three hundred million years, almost the whole duration of the Palaeozoic era: who are we johnny-come-latelies to label them as either ‘primitive’ or ‘unsuccessful’? Men have so far survived half a per cent as long." - Richard Fortey, Trilobite: Eyewitness to Evolution. Link to comment Share on other sites More sharing options...
TqB Posted November 22, 2017 Share Posted November 22, 2017 I agree it looks like a conulariid. Personally, I prefer them to trilobites. 1 Tarquin Link to comment Share on other sites More sharing options...

It does have a resemblance, but the morphology looks different. Yours appears to have a series of overlapping flat segments, whereas the conulariid photos I have seen show a rippled layer that is continuous. Yours looks more like a eurypterid although it doesn’t appear to be a perfect match there, either. Not sure what to say. Link to comment Share on other sites More sharing options...

They are ridges but the shadow makes it look like they overlap when this is not the case. The segments would be real skinny for a eurypterid and the general shape would be funky.

Here’s a close up of a Conulariid, both were from Wikipedia btw Agreed that the segments look too narrow for the eurypterids I have seen, which is why I wasn’t too confident about that identification. I will leave it to those of you more familiar with conulariids than I am to make that identification. In any event it’s a very nice find, congratulations!

jdp Posted November 22, 2017 Share Posted November 22, 2017 Another vote for conulariid. Link to comment Share on other sites More sharing options...
Peat Burns Posted November 22, 2017 Share Posted November 22, 2017 I'm in the conulariid camp as well. These serrations were what put me over the edge. 1 Link to comment Share on other sites More sharing options...
Ludwigia Posted November 22, 2017 Share Posted November 22, 2017 At second glance I'd also say conularid. Greetings from the Lake of Constance. Roger http://www.steinkern.de/ Link to comment Share on other sites More sharing options...

In my opinion, much rarer than trilobites in Ohio. Nice find! I wonder if more is present under the matrix. Link to comment Share on other sites More sharing options...
