Last year, I drew a Hyneria lindae, based off of recent discoveries and related fish. As soon as I finished it, I started working on a Hynerpeton bassetti, the Ichthyostegoid from the same site that is known from a shoulder girdle and a jaw, and possibly some other material as well. Hynerpeton is known to have been more muscular than Ichthyostega, because of the larger muscle attachments on its cleithrum (shoulder), and at one point was thought to have lost its external gills, but significant doubt has been cast on the evidence for this claim. Hynerpeton's jaw is not as robust as another stegocephalian from the site, Densignathus rowei, which was more derived and muscular. For this reconstruction, the skull (which is covered in skin but fully reconstructed) was based off of Ichthyostega, but the jugal bone was based off of a specimen from Red Hill that has been attributed to Hynerpeton. The shape of this bone affected those around it and suggest slightly different proportions in Hynerpeton than in Ichthyostega, especially concerning the shape of the orbit. The shoulder was incorporated so that the shape of the trunk would be correct, and the foot pads were based off of tetrapod footprints from the Early to Middle Devonian. The lateral line is again based off of its placement of Ichthyostega, as were the scales. In the background, above the water's surface, a forest of Archaeopteris spp. trees and Otzinochsonia beerboweri lycopsids is visible; within the murky river, the red mud that gave Red Hill its name after it was deposited is covered over with plants. This reconstruction is meant to be a sequel to my Hyneria lindae reconstruction I finished about five months ago; unfortunately, I have no specimens of Hynerpeton, which is very rare. If anyone would like to see any citations for the papers that I used in making this reconstructions, please ask below. Enjoy!

This Jaw was found and extracted from the wall at Red Hill in North Bend, PA by my son Ian (DevonIan Fish). It is similar in size to the jaws he discovered in 2014 which are now in the collections Academy of Natural Sciences in Philadelphia and will be used to re-describe Hyneria. -

Hyneria lindae Large tristichopterid fish tooth My first complete tooth from Hyneria without significant feeding damage. Largest one too, unfortunately broke apart when getting it out, but was able to salvage and glue together the major pieces. Catskill Formation Fammenian Pennsylvania -
A few months ago I found this bone at Red Hill before I learned of the need for a permit but didn't grasp its significance. Later I realized it was a jawbone section with four small teeth in it. Unfortunately I dropped it and the end of the most complete tooth fell off, but not before I was able to take pictures. I have not tried to finalize preparation for fear of destroying the remaining teeth. I can't see any sutures, at least not in the place they would be for a tetrapodomorph, and the teeth look more like Hyneria anyway. However, all Hyneria jawbones I've seen have two rows of teeth, a small one and one with longer fangs. The cross section is also hard to place. The teeth seem to start out round and flatten as it goes up. The first picture is as the bone is now and the second shows what the complete tooth looked like before it broke. Scale bar 1cm broken into 5mm halves. Teeth magnified 20x.

Teeth from the Tristichopterid Hyneria lindae, these are on the smaller side and quite partial but still have nice preservation and beautiful enamel. Late Devonian, Catskill Fm., PA.-

Hash of Hyneria and Limnomis bones from Red Hill, April 15, 2022 -
Hey everyone! I'm not the best with fossil fish; I need some help with ID. My friend told me this was a Bothriolepis plate, but I second guessed when I saw the frilling on the edge, as well as the overall shape. I know there are many fossil fish experts here...does anyone know what it is?

Hey guys. I'm looking for some help with this large mystery fish tooth from the late Carboniferous of Illinois. The closest match i can find is from the Devonian lobed finned fish Hyneria. But this is late Carboniferous almost Permian. Another contender just based on size is the Rhizodont. But it's not rounded. This tooth flattens out to two cutting edges that are very sharp. It honestly reminds me of a Barracuda tooth. This broken tooth measures about 20mm, but would have most likey been around 30mm if complete. It is associated with a Megalichthys scale and Orthanthus teeth. Any thoughts?

Hyneria tooth? Lithunanian erratic probably Narva Stage
D.N.FossilmanLithuania posted a topic in Fossil ID
Dear Guys, Today I splited small sandstone erratic, here I saw Asterolepis- like armour plates and found Hyneria tooth crown that is about 9 mm length and preserved with well visible cross section that lets to think it is polyplocadont like. The very similar greenish grey sandstones with red spots and the placoderm Byssacanthus pieces are decribed in the database fossiilid.info as from Narva stage (Middle- Late Eifelian, Middle Devonian) Talking about Eifelian tristichopterids I do not know any bigger forms, I just have heard about Tristichopterus. But judging by the size and the relief near root zone this tooth is especially similar to Hyneria teeth from Red Hill quarry, Australia. Maybe platycephalichthys is could be (it is known in Latvia and even Russia) but it is found only from Late Givetian and thrived in Late Devonian epoch... Please help me to find out anything about this question. Best Regards Domas

Tristichopterid, Hyneria Lindae Fish Fossils, Red Hill, Pa
devonIanfish25 posted a topic in Fossil Hunting Trips
This is my first attempt at a trip report so bear with me. In May 2014 my dad lead a trip for Delaware Valley PS to Red Hill. We identified some fossil bone sticking out of the face in the shallow channel margin. Excavation of the layer produced a 12 inch Hyneria Cleithrum along with many large scales. Also we identified the end of the lower jaw of possibly the same fish. Doug Rowe of the Field Museum determined the Academy would definitely want to keep it so it was left in place. He was able to expose about 7 inches the following week before reburying it. We returned in Aug. to try and finish extracting it. Excavation also produced a fragment of the palate with about a 2 inch vomerine fang and many pieces of a head plate which were reconstructed. We took out about 10 inches of the jaw bone with a portion remaining in the wall. The final trip was with NYPS in Sep. because the remaining jaw fragment was going to be difficult to cut around we brought our generator and a rotory hammer. The extraction of the remaining jaw fragments also exposed what appears to be the other half of the jaw. Total length of the jaw is about 15-16 inches making the fish about 8 feet long. The jaw material was sent to the Philadelphia Academy of Natural Sciences where prep work was performed by Fred Mullison. The jaws will remain in the Museums collections and add to the knowledge of Hyneria. fig 1.
