Howdy folks! I’ve had a lot going on so I haven’t been super active on here as of late, but I wanted to do a little recap of some of my favorite finds and acquisitions of 2023. Hope yall enjoy! Thanks for looking! First up is by far my favorite find from last year. This bug was collected as a ventral specimen in February, and was flipped and prepped dorsally by Jon Ginouves. Hypodicranotus striatulus is an exceptionally rare species from the Middle Ordovician Trenton Group of NY and equivalent strata in Canada. This is the first NY specimen I have ever seen or heard of coming out of strata outside of the Walcott-Rust Quarry. Up next is another piece from the same locality as the Hypodicranotus. I believe this came out of the site in the late spring or early summer. Generally, juvenile Gravicalymene magnotuberculata are near impossible to find, but I stumbled upon a mass plate containing around 20-25 specimens ranging from prone to fully enrolled. It is entirely possible that this is the largest cluster of this species ever collected, which is pretty sweet. This pic doesn’t show the whole plate, but you can get the general idea of how plentiful the trilobites are! This next specimen is just a cephalon, but it is from the iconic and very rare Walcott-Rust Quarry trilobite species Sphaerocoryphe robusta. This was found when I visited the locality in June with @KompsFossilsNMinerals . Normally I only focus on trilobites while collecting, but this past October I made a couple short visits to a Fiddlers Green Formation eurypterid site very close to my college campus. Eurypterid material is very sparse, but I did find some pretty interesting pieces. The most exciting of these was a partial Dolichopterus macrocheirus specimen showing the prosoma, 2 tergites and most of the appendages. Along with the usual trilobite suspects, I also ventured into some new territory strata-wise. I was able to visit an Onondaga Limestone locality several times during the summer and fall where I found half a dozen or so Odontocephalus selenurus specimens. Through my work in the Tully Limestone, I have become good friends with Steven Mize, who primarily collects the unit’s trilobite species. He invited me to come collect the Tully with him in July, which is when he gave me this beautiful enrolled specimen of an undescribed Basidechenella sp. While out collecting, Steve found this plate of 6-8 undescribed Asteropygine sp. , which he was kind enough to let me keep! During this past fall, I became very interested in the various Cambrian biotas of China. Here are a couple of Radiodont appendages I acquired. I believe the first one is Guanshancaris kunmingensis, and the second is Anomalocaris saron. This is my favorite trilobite I acquired from China. Although it is only a partial, this Redlichia mansuyi from the Guanshan biota exhibits one of its robust antennae!

Found this specimen in Pike County, PA. Here are some photos from different angles! This fossil has taken me in all different directions with regards to research. I have been unable to discern what this find may be. If anyone has an idea, I’d love to hear it! (My guess) Lepidodendron or Archaeopteris sapling branch??

Been finding a lot of these in the mahantango formation, but have been unsure of what they may be. Alongside these (what my untrained eye sees as) Spores, I have found many “V” shaped branches, with the little knowledge I have, my first thought is Cooksonia.. Hoping someone with more knowledge can provide a definitive answer! There are three examples within this one rock and I have many stems in other rock!

Trilobite in Matrix

I have some images of a trilobite fossil I am interested to collect. Can I have some opinions if it is worth collecting and if it’s legit please.

Trilobite Fossil real or fake?
Toast123 posted a topic in Is It Real? How to Recognize Fossil Fabrications
It was collected from Bou Dib Formation near Mrakib. Im wondering if they are authentic or fake. Why is the stone they’re on a different color than the rest of the rock?

I have a find from my hunt last Tuesday that has me stumped. As I took a break from pounding rock I took a walk around the site to surface scan the surroundings. I saw a slab with a high concentration of spiriferids. I decided ti try to break the grouping off the slab. This resulted in a Mystery (for me) brachiopods coming out with one of the spiriferids attached as well as some imprints. The item does not photograph well but hopefully someone can make out what it is. It measures 3 inches across. Found in Middle Devonian Hamilton Group Moscow Formation. @Fossildude19 @Jeffrey P

From the album: Mahatango Formation
The only specimen I've ever collected of this elusive trilobite, found in the Montebello member and associated with many Eldredgeops. The specimen would be 2.5 inches if prone.-

Authentic osteostracans from Spitzbergen?
Amontano posted a topic in Is It Real? How to Recognize Fossil Fabrications
Can anyone help me with if this looks like an authentic collection of head shields from boreaspid and cephalaspid ostracoderms? Seller states the species are Spatulaspis, Boreaspis and Cephalaspis. Not sure about the identification of Spatulaspis based on morphology but I've also personally not seen ostracoderms with such detail and wonder if their quality is too similar to the matrix. The stated locality is from Wood Bay in Spitzburgen which fits with Boreaspis and Spatulaspis. I would love to add a beautiful assemblage of stem gnathostomes to my collection but am not positive about the authenticity. Would appreciate any thoughts!
