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 mos

Hi. I have absolutely no information on this particular specimen. It was picked out of a group of fossil fish most of which were Eocene in age. I suspect it might be Osteolepis but really I have no idea! Any observations would be most appreciated. Thanks.

Lysorophian donated to Field Museum
deutscheben posted a topic in Partners in Paleontology - Member Contributions to Science
Last year @jdp was kind enough to identify the tiny and jumbled skeleton I found in a concretion in eastern Illinois http://www.thefossilforum.com/index.php?/topic/107472-mysterious-jumble-inside-pennsylvanian-concretion/ as a lysorophian tetrapod and direct me to the Field Museum in Chicago as a possible repository for it. This month I finally completed the donation and it has been added to their collection, a fantastic event for someone who has been visiting the museum for more than 30 years to gaze in wonder at their world-class collection. Thank you again to @jdp and The Fossil Forum for m- 14 replies

Another driveway find. Is this a sponge of some kind or possibly and bone from dorsal fin? Kind of looks in the shape of the ulna i cant find any reference on what an isolated one looks like. Can bones be calcified like this? i have no idea.

New to geology, so excuse my paltry terminology. Description: Tubes, many branching, between 1-3cm in diameter, in places as thick as a forest root system, material very sandstone-y, surrounding material clay. from my research these seem like burrow casts of... worms? tetrapods? do burrow casts form in such abundance?

Sources on the relation between modern Lissamphibia and stem tetrapods
Mahnmut posted a topic in Questions & Answers
Hello together, I am looking for papers about the relation between modern amphibians and stem tetrapods (this time not for model building purposes but for an academic paper I write on amphibians as model organisms ( I have the medical topics covered but wanted to include a bit of palaeontology). Also, is there any hint in the fossil record on limb regeneration like some modern amphibia can do? Thanks, J -
A new discovery of a 375 million year old Tetrapod called Parmastega aelidae with some very unique features from the Komi Republic. http://www.sci-news.com/paleontology/devonian-tetrapod-parmastega-aelidae-07730.html Thought some of you might find this interesting.

Just finished the prep on this guy. When i first found this i thought it was a jaw. Now after it's finished it looks more like a possible pectoral girdle or gill plate/skull element from a lobed finned fish/tetrapod. What do you guys see? I can not find anything like it on thee ol' interwebs. It's late Carboniferous and i have found everything from micro to large fish scales, flora, Orthacanthus teeth and other bone chunks in this same layer. Also there is a neat impression of a Lepidodendron on the underside of this piece. Kinda a nice touch when fish were evolving to

A Very Good Problem to have in the Carboniferous
fossilized6s posted a topic in Fossil Hunting Trips
In the last two weeks i have found two new very promising fossil sites. They are on private land that i have permission to be on. And please don't ask where. There are so many things that i have to leave many behind. I hope i am lucky enough to find something truly amazing from these sites and share them with science and ultimately all of us. I believe this to be the first Orthacanthus sp. specimen ever found in this area of Illinois. It would be pretty neat to add this awesome predator to this fauna. As found: After prep:- 27 replies

Obviously, the tetrapod is from the Carboniferous Missippian...out by the old airport...does anyone know where that Casselman formation/Conemaugh Group is? Even though the Fedexia was found in 2004, it would be nice to resume some work and see what else is there...any ideas, any interest?

Here's the link to the original blog post: http://redleafz.blogspot.ca/2013/04/somewhere-in-parrsboro-there-are.html A few days ago I drew a map of the West Bay/Cape Sharp area South-West of the town of Parrsboro, Nova Scotia. I had wanted to check the Jurassic age basalt cliffs of Cape Sharp and poke around a bit to see if I could come out with anything. On the cliffs on each side of Cape Sharp are Carboniferous sandstone cliffs which displays a fascinating record of trackways, especially those of tetrapods. I had marked on my makeshift map where the location of a possible access point to th

This fossil was inherited so unfortunatly I don't know the background on it. The creature within is approximatly three inches in length. It appears to have skin like an alligator with the tail of a fish, most resembling a coelocanth tail. My interest in the fossil was renewed after reading about the discovery of tiktaalik. Unlike other supposedly pre-tetrapod fishes, there is no sign of any anterior fins (besides caudal) or appendages. This has given pause to some professional paleontologists who will not even hazzard a guess as to whether what I have is, as I believe, even a vertibrate. (I ca
