Looking for some experts on these attached images. These are just ones I can’t figure out. Scale in metric. I had a successful hunt at the end of 2023. Soon I’ll be adding a photo album of this and some of my other finds from various locations. Overall, I found Ageleodus pectinatus teeth, Hyneria lindae teeth and scales, Megalichthys mullisoni scales, Langlieria radiatus scales, Holoptychius sp. scale, acanthodian fish spine, Phyllolepis rossimontina armor, Turrisaspis elektor armor, and plant leaves and stems. EDIT: Location - Clinton County, PA.

I recently finished this reconstruction of the giant Tristichopterid fish, Hyneria lindae, from the Catskill Formation in Northern Pennsylvania. It is based off of the most recent (2018) paper concerning Hyneria lindae, which can be found here. Made in Paint.net, many skull bones are re-shaped from my previous reconstruction I released a couple years ago, including the opercular (gill cover) and associated bones. The color pattern I used is based off of the Norther Pike, which is very similar in overall form and likely also lifestyle to this fish. The scales and their frills are based off of scales figured in the paper, as well as fossils I have collected myself from the legendary Red Hill fossil site in North Bend, PA. The body is based on Eusthenopteron foordi, with special reference to the P-22 specimen that revealed so much about this related fish. The tail is based directly off of the amazing Hyneria specimen found in the paper and in the Red Hill Field Museum. Parts of the tail in the reconstruction were even traced from this fossil, which is pictured below as well. The picture below that is of a Hyneria opercular I excavated, which inspired me to finish this project. While Hyneria was a very low-metabolism, ambush-hunting fish, I wanted to depict it peacefully, and yet not in a mostly static pose while waiting for prey. I hope this reconstruction provides an accurate depiction of Hyneria lindae as we know it in 2023, but with more detail than the 2018 Jason Poole reconstruction which helped me greatly to reconstruct this ancient Devonian fish. And the Hyneria lindae tail from the Red Hill Field Museum: The Hyneria opercular from Red Hill, from a 6-8 foot long fish: Resources I used to make this reconstruction: For reconstruction of the skull bones, scales, and tail: https://www.researchgate.net/publication/324883784_New_description_and_diagnosis_of_Hyneria_lindae_Sarcopterygii_Tristichopteridae_from_the_Upper_Devonian_Catskill_Formation_in_Pennsylvania_USA The Eusthenopteron foordi reconstructions on this website were incredibly helpful, especially when illustrating the mouth of Hyneria. Coincidentally, I reconstructed the Hyneria mouth at a similar angle to one of the pictures on the website, way before I knew about it. https://www.cullentownsenddesign.com/eusthenopteronfoordi For ecology and lifestyle: https://www.researchgate.net/publication/329371242_Long-bone_development_and_life-history_traits_of_the_Devonian_tristichopterid_Hyneria_lindae For the rod-like projections found at the bases of the fins: https://www.researchgate.net/figure/The-famous-P-222-specimen-of-Eusthenopteron-foordi-before-its-skull-was-destroyed-by_fig5_362872177 For the fins themselves: https://www.researchgate.net/publication/213770274_Vertebral_development_in_the_Devonian_Sarcopterygian_fish_Eusthenopteron_foordi_and_the_polarity_of_vertebral_evolution_in_non-amniote_tetrapods The release of the Hyneria udlezinye paper to the public proved essential to my reconstruction, because the full skull reconstruction helped me fill in the gaps that exist in our knowledge of H. lindae's anatomy. Its different proportions caused me to look at those of H. lindae's more closely. https://www.researchgate.net/publication/368718778_A_high_latitude_Gondwanan_species_of_the_Late_Devonian_tristichopterid_Hyneria_Osteichthyes_Sarcopterygii The 2018 Jason Poole reconstruction of Hyneria lindae was very helpful and helped inspire the project. https://www.anspblog.org/illustrating-a-devonian-predator-part-2/ The older, 2009 Flick Ford reconstruction of Hyneria can also be found on this post, above the newer one. This one has outdated proportions but was helpful because of its high detail, especially when reconstructing the fins. The work of Paleobiome, which can be found on this forum, also proved extremely helpful. Working with Paleobiome with his reconstruction of Hyneria lindae helped me look critically at my own as I was working on it, resulting in a higher detail, more accurate reconstruction with more realistic lighting. Check out his reconstructions for a full, real-time, first-person simulation of Red Hill, including his Hyneria, here: https://sketchfab.com/paleobiome/collections/famennian-red-hill-pennsylvania-f1cd53241c884e1884e99f40c9f2c304 For my previous reconstruction of Hyneria lindae, based very (a little too closely?) off of one of Jason Poole's older 2005 reconstructions of H. lindae, you can see it on my website, here. In this reconstruction, the fins were not shaped correctly, and were supported by extra bones, the body tapers in a peculiar way, the opercular series, including the submandibularbranchialstegal (whew!) bone were too large, the jaw too jutting, the head the wrong shape and many of its bones reconstructed incorrectly. The water is a simple gradient. I feel that my newer reconstruction is a major improvement and has helped me grow as an artist. To see some of my other recent artwork, visit my Seven Stars page, where I am in the process of building an educational guide to a special Middle Devonian fossil locality where beginner through expert fossil hunters and paleontologists have enjoyed collecting fossils for more than half a century. The guide is far from done and will not be for a long while, but it includes diagrams, life reconstructions, identification guides, and information about many fossil groups. It was made with beginners in mind, but will be useful for experts too.
