Miocene_Mason Posted July 9, 2017 Share Posted July 9, 2017 I got to hunt on the trilobite ridge for a very short time, thanks to @GordonC for letting me know it existed and Jeff from this site for the directions and other tips. I had a very short time to hunt, but it was productive. I've got lot of spiriferids and other goodies, but best of all the first thing I saw, as if placed by divine intervention, a trilobite pygidium! This is the first real trilo I've found, although I find an extremely small piece of one in Maryland, so this is why I'm very excited even for a fragment. Any one know the species? I know it could do with some prep, but it's to delicate for me to attempt. If any pros want to prep it for me extremely cheaply, pm me. I can get more pictures if needed. “...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...
Fossildude19 Posted July 9, 2017 Share Posted July 9, 2017 Trilobite Ridge, I believe, is Lower Devonian - so not Mahantango Formation. Possibly Phalangocephalus dentatus , Glenerie/Port Jervis Formation, Tristates Group. That looks like it won' t prep out much. See JeffreyP's Lower Devonian gallery for comparison.

Even a fragment is pretty good for Maryland! Mind posting a picture of it? Don't know much about Trilobite Ridge, but I believe that it is stratigraphically equivalent (more or less) to the Oriskany Sandstone in Maryland. Dalmanites sp. is a fairly common genus in that, as are species of Phacops. Fossildude probably knows more though, as well as @piranha. Link to comment Share on other sites More sharing options...

Thanks for the information, I assumed mahantango because that was near and I had no knowledge of the formation. I agree with Phalangocephalus dentatus, is this a common find? As for the prepping, I might be able to get some off some of the rock myself. “...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...
piranha Posted July 9, 2017 Share Posted July 9, 2017 The axis of Phalangocephalus dentatus is much too narrow. A better match is the Lower Devonian homalonotid: Trimerus vanuxemi 1 Link to comment Share on other sites More sharing options...

I have it on my gallery, as well as a post somewhere. I thought that you may have replied to it? I'm not sure though, it was a while ago. I'll see if I can find it.

A better match is the Lower Devonian homalonotid: Trimerus vanuxemi Excuse my lack of proper terminology, but in mine this part looks steeper and and the edges look "spinier". Is this just how it's worn, or intraspecies variation? “...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...

It was actually never fully resolved, although it looked closest to elderegeops to me although your ID was devonochonetes and spiny urchin as well as rugose coral. “...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...

I find it odd that you agreed so quickly on Phalangocephalus dentatus. For the record, here is the pygidium of Phalangocephalus dentatus. 31 minutes ago, WhodamanHD said: Excuse my lack of proper terminology, but in mine this part looks steeper and and the edges look "spinier".

This example of Trimerus matches better with the one you found. 1 Link to comment Share on other sites More sharing options...
