The popular collected trilobite Phacops rana is well embedded in literature for over a hundred years. Then in 1990 it was renamed Eldredgeops rana. A lot of collectors did not understand why the name change and I would like to attempt to clarify why the change. The purpose of this post is to point out the differences I have observed between Phacops and Eldredgeops and explain why "rana" is an Eldredgeops and not a Phacops. The literature on phacopid systematics is in a mild state of disarray. Authors have built on the errors of previous authors. There is no good English diagnostic descrip

Mystery Trilobite From Western New York: Non-Greenops Non-Eldredgeops Phacopid?
NoahW24 posted a topic in Fossil ID
Last year, while looking around a quarry in Upstate NY (Middle Devonian, Moscow fm), I stumbled across a trilo-bit I have had trouble placing. It’s some kind of phacopid, but not an Eldredgeops, and it just doesn’t feel like a Greenops. Found at a site with associated Dipleura dekayi, Greenops, Eldredgeops, Tornoceras, orthocerid nautiloids. The first photo is the mystery bug in question, followed by a Greenops and an Eldredgeops from the same site for easy side-by-side comparison. The final picture is a close visual analogue I’ve found online, though it is Moroccan and I -
I first became interested in fossil collecting while living in Michigan, so any fossils I find in the state are somewhat special to me. Last summer I took a quick trip up to Alpena, MI to collect the Devonian in the area. Lots of interesting things were found, including two Eldredgeops. Neither is complete, but I was still quite happy to find bugs in a state that does not give them up easily.

Hi all, about 2 weeks ago during my spring break my father and I made the 6 hour trip up to Buffalo NY to collect at Penn Dixie. Our main focus is to bring back blocks for our weathering pile in the back yard, so we worked from around 11am to 5pm moving chunks and transporting them to the car. Here is a photo of me driving a wedge into the huge row of rock we were working on, it was pinned and took probably 30 min and a lot of thinking to break it free. Ill attach photos of some finds from the day below. Disarticulated Eldredgeops and a

I’ve spent about a year now combing through PA’s Mahatango, attempting to collect all of the trilobite fauna present in the formation. At this point I have all but one, Odontocephalus being the only that’s eluded me thus far. A big thanks to @Dean Ruocco for showing me around and in general refining my craft man. IMG_0717.MOV

Hi everyone, I was wondering if there was an easy way of differentiating Viaphacops and Eldredgeops, as apparently Viaphacops is in the Needmore shale. I am heading down to Lost River in WV to do some hunting and since it is Needmore, I wanted to know. Any help appreciated.

From the album: Nautiloid’s Trilobite Collection
While it’s nowhere near as nice to look at as a complete bug, this is still a pretty peculiar fossil. It’s a ventral Eldredgeops rana cephalon with the hypostome still attached, something you don’t see very often. Collected from the Middle Devonian Windom Member of the Moscow Formation, Central NY on August 19, 2022.© Owen Yonkin 2022

A reconstruction of the Mahantango Formation
Bringing Fossils to Life posted a topic in Paleo Re-creations
I just finished a reconstruction of the Mahantango ecosystem, based off of fossils I have found at corresponding sites. This certainly does not cover all species in this formation, but many of the most prominent (Sorry no Dipleura, haven't done that one yet). I recently learned about Striacoceras and re-identified many of my orthocerids as this obscure genus. Striacoceras is the brown orthocone in the background. I included two crinoid genera, (left to right) Ancyrocrinus and Botryocrinus. an Eldredgeops searches for prey. There are several Mucrospirifer brachiopods, some Orthonota bivalves, a -
After work had the chance to try out a new (to me) outcropping of the Mahantango. While the rock I split was mostly out of situ there was exposure along a cliff that I avoided just to be safe. This area seemed to be a different environment than Mahantango spots I have hunted in the past. There was more crinoids and even some horn corals. I managed to find a few trilobites, mostly Eldredgeops though I did find a partial Greenops. My highlights were the largest Mahantango Eldredgeops I have personally seen (though I am sure someone on here has a larger one!) as

I recently went to Penn Dixie for the first time and was not disappointed. Our tour guide first showed us the youngest rocks, then the pyrite. Here I found a tiny juvenile Tornoceras, Bactrites, and out guide showed us that individual septum can be found (see this post). I also found a fragment of a non-pyritized tiny Eldredgeops thorax. I found what HynerpetonHunter says is worm coprolites, and a few tiny brachiopods. Then, we went to the place where phosphate can be found. After that, we stayed a little at the place where fossils from the oldest layer were deposited in the soil, and I found
