ranitomeya Posted May 1, 2017 Share Posted May 1, 2017 Anyone have any idea what this might be? Was found last week while splitting Widder shale looking for Greenops. I usually don't take much home other than trilobites but I have never seen anything like this before. From Hamilton group, Widder formation, was found alongside Greenops bits. Any ideas would be appreciated. Thanks! Link to comment Share on other sites More sharing options...
Micah Posted May 1, 2017 Share Posted May 1, 2017 I'm no expert, but maybe some kind of cephalopod on the bottom right and the bumps appear to be braciopods or bivalves with crystal that filled in a crack between them? My first impression was that it was simply some kind of cavity that filled with quartz or some other crystal often fossils form those cavities though. My thoughts, but wait for an expert.

Fossildude19 Posted May 2, 2017 Share Posted May 2, 2017 Hard to say, but I would look into phyllocarid mandibles, perhaps. Cropped and contrasted.

ranitomeya Posted May 2, 2017 Author Share Posted May 2, 2017 Thanks! It does look to be a phyllocarid mandible after comparing it to other pictures. I appreciate your insight Fossildude19. Link to comment Share on other sites More sharing options...
FossilDAWG Posted May 2, 2017 Share Posted May 2, 2017 I have collected a phyllocarid, probably a Rhinocaris, from the Widder. Echinocaris is also known. Copeland and Bolton (1979) have an excellent publication on Ontario eurypterids and phyllocarids, including illustrations of some from the Widder and Arkona Shale (link here).

abyssunder Posted October 22, 2017 Share Posted October 22, 2017 My fist impression was a jaw. Now, seeing the experts opinion, I'm sure I was not wrong.
