MarcusFossils Posted July 23, 2016 Share Posted July 23, 2016 Hello all I'm out at my hunting spot as I write this, and have found something quite exciting. This location isn't know for any particularly large fossils, except I seem to have found something quite big. And the only big fossils around here are of Megalograptus: http://www.mpe-fossiles.org/resources/Chartier_et_al-_2002.pdf 1) 2) Any help in this ID would be much apprecieted!

MarcusFossils Posted July 23, 2016 Author Share Posted July 23, 2016 The fossil is approximately 12cm long and 8cm wide, and has a granular surface texture (like a trilobite carapace).

Raggedy Man Posted July 23, 2016 Share Posted July 23, 2016 I do not see it. It's possible the details aren't showing up in the image. Another possibility is that I'm just blind ....lol Some times we do not see what's staring us right in the face. You have any images of the item dry? ...I'm back.

Keep in mind the fact that megalograptus was 4ft long. The fossil would only be a small section of some part of it's body. I'll try taking a better picture Website: https://www.instagram.com/paleo_archives/ --------------------------------------------------------------------------- “It is by no means an irrational fancy that, in a future existence, we shall look upon what we think our present existence, as a dream.” ― Edgar Allan Poe Link to comment Share on other sites More sharing options...
MarcusFossils Posted July 23, 2016 Author Share Posted July 23, 2016 I suppose it could be a segment of a cephalopod...but I doubt it Voila: Website: https://www.instagram.com/paleo_archives/ --------------------------------------------------------------------------- “It is by no means an irrational fancy that, in a future existence, we shall look upon what we think our present existence, as a dream.” ― Edgar Allan Poe Link to comment Share on other sites More sharing options...
FossilDAWG Posted July 23, 2016 Share Posted July 23, 2016 I'm not seeing anything that resembles any part of a sea scorpion anatomy. It looks like a flattened portion of a large straight-shelled nautiloid to me. Don 2 Link to comment Share on other sites More sharing options...
TqB Posted July 23, 2016 Share Posted July 23, 2016 I'm not seeing anything that resembles any part of a sea scorpion anatomy.

Don I agree - a good find though and apparently a rarity from there. 1 Tarquin Link to comment Share on other sites More sharing options...
MarcusFossils Posted July 23, 2016 Author Share Posted July 23, 2016 I'm not used to finding any cephalopods other than Geisonoceras and whatever this ubiquitous like guy is: Website: https://www.instagram.com/paleo_archives/ --------------------------------------------------------------------------- “It is by no means an irrational fancy that, in a future existence, we shall look upon what we think our present existence, as a dream.” ― Edgar Allan Poe Link to comment Share on other sites More sharing options...

I'll try taking a better picture They are also not 4 ft. long when born/hatched? I'm sure not everything we find in this world is adult yet.

Jeffrey P Posted July 23, 2016 Share Posted July 23, 2016 To me that appears like a piece of a pretty large nautiloid. Nice brachiopod too. Congrats. 1 Link to comment Share on other sites More sharing options...
MarcusFossils Posted July 24, 2016 Author Share Posted July 24, 2016 (edited) For future reference, does anyone have any papers describing what actual Megalograptus material would look like?

Palaeontographica Americana, 32:301-358 LINK Thanks for the papaer I was browsing through the plates, and really did find that the fossil I have looks like it could be a section of the metasoma...the size is right, the granular surface is unlike a cephalopod and look like the surface of the meatsoma pictured in the plates..should I bother to upload more photographs with a proper camera or are we ceratin this is just a cephalopod segment?

MarcusFossils Posted July 25, 2016 Author Share Posted July 25, 2016 I'm going to tag this fossil as being a segement of Endocers sp. It's not a Lorraine Formation species, but it's the only ID that matches Website: https://www.instagram.com/paleo_archives/ --------------------------------------------------------------------------- “It is by no means an irrational fancy that, in a future existence, we shall look upon what we think our present existence, as a dream.” ― Edgar Allan Poe Link to comment Share on other sites More sharing options...
