Hash of Hyneria and Limnomis bones from Red Hill, April 15, 2022 -
So here is my 2021 summary of my collecting trips to the late Devonian Catskill formation of Pennsylvania. I have been collecting for the Academy of Natural Sciences in Philadelphia for the past few years. A Tristichopterid skull collected at the Cogan House exit on RT15 in the 2019 season was just described as a new species of Eusthenodon in JVP, Daeschler et. al.. Very exciting! All three trips to PA this year included Red Hill. While the forestry department was very limiting on the use of power tools, they seem to not care too much if people collect with hand tools. The problem is most of the easier surface and near surface material has been collected over the many years the site has been worked. Now, the only way to discover any new tetrapod material is to move large quantities of rock. So that's been the challenge. How much stone can be moved with hammer and chisel with 64 year old wrists? Anyways, I was able to recover a number of interesting specimens although nothing has been id'd as tetrapod so far. These have all been sent to ANSP for analysis. This head plate with what I thought were lateral line canals (Y shape in middle) had a different ornament from other specimens of Hyneria I have. I had also convinced myself the curved surface on the left side and lower image appeared to be orbits but the experts determined it to be just a run of the mill Hyneria post parietal shield. ….It was exciting for a while. Even though this endochondral bone was found in with some exceptionally well preserved material it must have experience some significant transport before being deposited. With a thin blade at the top and some hefty bone at the bottom, I thought this might be id'able but no such luck. I still feel like it must be a shoulder girdle. Not sure what else it could be?? This is another endochondral bone found closely associated with the others. It is minimally a mesomere element of a fin but compares well with the radius of Ichthyostega (see below). Unfortunately, it again being an isolated element has not been id'd at this point. Unfortunately, this mesomere element split when I was removing the head plate. It seems to compare well with an ulna/tibia from a sarcopterygian fin. Here it is with the above "radius"? Finally, the one id'd significant fossil from the season! This bone was found at the Cogan House exit on RT 15. Ted Daeschler was pretty quickly able to id it as a lungfish lower jaw, probably something like Soederbergia.

On August 15 I went to Red Hill near North Bend, PA, with my parents, grandparents, and aunt along with my friend. The weather was not much better than now. It was searing hot. Our first stop was the North Bend Municipal Building, which housed the Red Hill Fossil Display. We met the discoverer of one of the earliest amphibians ever, Densignathus, named Douglas Rowe. He led us back to Red Hill, and we started to fossil hunt. I was determined to carry on the hunt for a good transitional fossil, like Hynerpeton. I immediately found a nice-sized Hyneria scale. After hunting for a good while, I had found lots of Hyneria material, as well as Turrisaspis, Ageleodus, Gyracanthus, Limnomis, and Megalichthys. But I knew that I could possibly never find a Hynerpeton in my entire life. But I kept going. Finally, ten minutes before we left, I found something interesting. I was right below the place where Daeschler discovered Hynerpeton back in ‘93, and was feeling the effects of heat exhaustion. I was ready to give up when I saw a rectangular, centimeter-long chunk of bone. I was intrigued, but I had no time for hand ID. I needed water ASAP. But the next day, I was observing a document of the fin model of Eusthenopteron. I noticed something small next to the fin support. It was rectangular, almost identical to my bone. It was a scute. To be sure that I had a scute of an amphibian like the one on the Eusthenopteron diagram, I looked to Ichthyostega. Sure enough, Ichthyostega’s scute was almost a carbon copy of mine. I had a Hynerpeton or Densignathus scute. Images of my fossils will be coming soon!

Hi all! I pulled this fossil out of Red Hill, a Devonian site in central Pennsylvania. I thought it looks like it could possibly be part of a placoderm but I’d love to get some help with further identification. Thanks in advance!

Hi everyone! I have what I was told is Red Hill matrix that has been sitting on my porch for a very long time now... Anyone familiar with this matrix that can help me out? I am wondering if it does in fact look like Red Hill and the best way to break the matrix down? Some are very large chunks that have too much quartz to dissolve I think but here are some of the smaller pieces. As you can see there's a lot of shells in there... lol Any feedback appreciated! Thanks in advance.

With not a lot of new material to obsess with (broken arm) I have been going through old specimens to see if there are unfinished prepping and ID needed. Here is a set of scales/scale impressions collected in 2014 at Red Hill, late devonian (Famennian) site in Pennsylvania. Found in the shallow channel margin (red sediments) with what has been ID'd as a couple scapulocoracoids of the acanthodian, Gyracanthus (plus a fin spine). They are almost certainly sarcopterygian but not sure what clade. Has anyone, Archie? seen similar scales. Thought they might be Holoptychius but they don't look like the classic Holoptychius scales and they were not at all common in this upriver environment. Doug Rowe who oversees the site and runs the outstanding museum there, suggested they might be Rhizodont but nothing I've seen of Rhizodont scales looks anything like these. Thanks for any help.

This last Saturday was a repeat of the previous collecting day I had on Oct. 8 at Red Hill, PA. Once again a tailgate of specimens was found. The most of my digging is in the Green Shale layer. That is where I find the most plants. For the most part, the fossils were all Archaeopteris with one nice macilenta species. A species I don't find much of. The last close up pic is a textbook example of spore cases found on fertile branches of Archaeopteris.

Some of us fossil collectors believe there is no such thing as a bad day fossil collecting. Well, yesterday at Red Hill, PA it was muddy, rainy and cold. I'll will have to admit it was still a good day fossil collecting. One of my objectives to collecting at this Upper Devonian site is to find fossil plants, namely Archaeopteris. Well it happened big time. A picture of my truck tailgate tells the whole story of my catch of the day. What was found were 3 species of Archaeopteris, fertile and infertile leaves, large plates and small pieces that I liked too much to discard.

Going To The Red Hill PA Site Next Weekend, Need Any Advise You Can Give
njfossilhunter posted a topic in Fossil Hunting Trips
I'm so excited about going to the Red Hill Fossil site in PA with DVPS club and would like some or any advice on collecting there. This is my first time at Red Hill and I did find somethings about the site online but nothing about on how to collect ,,where to look or what to bring with me. Any help would be greatly appreciated. I will post pictures of my finds .. .... if any. Thank You -
This summer I went on a trip to Red Hill, the famous freshwater vertebrate locality in Pennsylvania. The fossils found at the site are from the Duncannon Member of the Catskill formation, which is Famennian stage Devonian in age. I was lucky enough to find an area they had recently used a jackhammer to expose new fossils, in which I found loads of great fossils. I ended up with a lot of unidentified fossils, so I need some help with these. I think this is a fish bone: I'm pretty sure this is a megalichthyidid scale. I like how it is colored! Fish chunks. I don't know if these would be identifiable, but I would at least like to know what sort of fish they're from. Placoderm, maybe?

A plate of stems and branches from the "Red Hill" U.Devonian site near Hyner, Pennsylvania. Catskill formation I believe.

This summer, I was fortunate enough to get to go to the famous Red Hill site in Pennsylvania. I found lots of awesome fossils, including teeth, scales, and bones. I was lucky enough to find a spot they had recently used a jackhammer to expose new fossils. In the piles they had broken out of the hillside, I found nice unweathered bones and a few small spines. I would like to prep the spines out of the rock, but the rock from Red Hill is hard and does not break down easily. One of the spines: The back of the rock has lots of bone chunks and stuff:

1. Any ideas what this Red Hill fragment might be? I just discovered this in the red shale from our Red Hill trip in June. This is an odd but well defined fragment from the 361 million year old Devonian site where tetrapods crawled onto land - not sure if this is shell material or part of a Devonian fish - about 1 cm - any ideas? 2. Is this a trilobite or shell? (Devonian/Mahantango/Juniata County PA) - about 5cm long: 3. I previously posted this but since found this oblong shell in a reference book - believe it is the bivalve Nuculites - I identified this bivalve after posting - this oblong shell is about 2 cm and retains some of its striking iridescence - from Tully NY (windom/moscow formation):

This image on the right shows a tiny Devonian fish spine from our June trip to Red Hill, PA - any help identifying this would be much appreciated. The long vertical fossil immediately to the right looks like the fossil of a minnow sized Devonian fish but [Herb] suggests it is actually a plant - archaeopteris - he has a keen eye! It is possible to peel back more rock covering the stem to verify but we're new to fossiling and this might be a bit tricky for us to attempt. More photos from our Red Hill trip are included in the Members Gallery including Hynaria and Placoderm teeth, scales, and other fossils. The contrast of the green and red shale is striking. The greenish grey shale is pond or lake mud that dried up approximately 361 million years ago and the red is mostly fossilized soil. More of our Red Hill fossils are included in a posting in the Members Gallery.

We collected these fossils at the classic Devonian site at Red Hill in PA (where some of the first early tetrapods that crawled onto land were discovered). Shown are a Placoderm tooth, a very clear Hynaria tooth impression, Hynaria dorsal spines, Placoderm scale (note the texture on the scale) and a fragment that we aren't sure if it's skin or bone. Note the tiny white dorsal fine/spine from a Devonian fish. Most intriguing to us is the vertical fossil next to the white dorsal spine which looks like a full fossil of a minnow sized fish - I added a separate horizontal image of this and the horizontal has a piece removed to reveal a "lobe" at the left side. Since posting this it has been suggested that the long fossil is actually a plant - archaeopteris - and what we thought was a "tail" is actually a leaf. However, the white bony dorsal/spine fossil still appears to be a Devonian fish. This was our first fossil hunting trip but although we are new to the field, we are enthusiastic about our new avocation. Doug Rowe who co-discovered and manages the Red Hill site, was extremely patient and helpful. Cathy Young and Karenne Snow led the trip, which took us to half a dozen Devonian and Ordovician sites and introduced us to a wide variety of fossil rich terrains.

Today was my first ever visit to Red Hill, the famous upper Devonian site where collectors have found a diverse ecosystem of fish and plants from one of the first forests. I was hoping to find a nice Hyneria tooth but instead I found most of a fish! It's small, only two inches or so long, and incomplete with the head missing, but you can clearly see the tail fins and what looks like a dorsal fin. These pics were taken in the field and the sun wasn't out so I did a little bit of contrast enhancement to clear them up a little. I spoke with Doug Rowe, who manages the site for the Academy of Natural Sciences in Philadelphia, and he said it was one of the first ray finned fish and called it Paleo-something or other. I was so excited that I didn't write it down. Does anyone have any idea who this might be? The only ray finned fish listed on the Red Hill website is Limnomis delaneyi but that doesn't sound like what he called it.
