Hello all, In my investigation of the fauna of the Devonian Mahantango Formation, I have become quite interested in the trilobite Dipleura dekayi. I have not yet had the opportunity to encounter this bug on the field, but it’s size and strange appearance have draw my interest. From the sources that I have read regarding the Mahantango and Hamilton Group formations in Pennsylvania and New York, I have noticed that trilobites with a very similar appearance have been referred to the separate genera Dipleura and Trimerus. In Fossil Collecting in the Mid-Atlantic States, Jasper Burns seems to treat Dipleura and Trimerus as synonyms. However, Wikipedia (I am fully aware this is not the most reliable source) has separate pages for Dipleura dekayi and Trimerus dekayi. I have also heard more references to Trimerus when the specimens are found in the New York area and I vaguely remember a posting on the forum where the question of Dipleura vs. Trimerus was addressed but which post that was has escaped me. Here are the main questions that I have regarding this topic: 1.) Are Trimerus dekayi and Dipleura dekayi different valid trilobite species or are they synonyms? If they are synonyms, which would be the most proper to use? 2.) If Trimerus dekayi and Dipleura dekayi are two different valid species, how can they be differentiated? Does this depend on the region where the specimen was recovered? 3.) Are there other species of Trimerus present in the Mahantango Formation/Hamilton Group and how can they be identified and differentiated from Dipleura? Thank you in advance to all who view and comment on this post. I am very eager to learn more about Mahantango fauna and hopefully it will not be long before I find my first Dipleura/Trimerus in the field.

Last weekend I took a trip to Buffalo and Rochester to do some fossil hunting in between visiting friends and family. This weekend may have been the best luck of the year so far and have accumulated to some of my favorite finds of all time. My first stop was at a location in the southern tier of Buffalo where I found some complete trilobites and pyritized gastropods and cephalopods. My second stop was in Rochester, I have a few places that I explore every now and then for Lockport Formation fluorite and calcite when I am in town for work. This time around I actually had better luck finding fossils, but I did manage to find one nice cluster of fluorite. If anyone has good resources or literature on identifying Lockport fm fossils please let me know! Finds from Buffalo: Recency bias, but this might be my favorite find in a long time; I have been looking for one of these forever as a complete. E. rana, with spotted camouflage patterns on the body of the trilobite. Hard to see pictured. These spotted trilobites have been reported in a few localities in WNY Middle Devonian strata. I saw a short article about it here: LINK TO ARTICLE Second lucky find is a complete Greenops boothi. The head is buried under the matrix and is poking out the other side. Doesn't photograph that well, but it came out in great condition luckily. I only have a few of these complete and this is by far the nicest one. Rusted pyrite, small Tornoceras uniangulare. Rusted gastropod fossil, have not looked into detail or species yet. Gastropod poking out of a pyrite nodule, really like this one. Rochester Finds: Dolomite replacing the outline of a gastropod Chain coral, my first find of this kind in New York. Dolomite replaced solitary horn coral. Bonus: I saw this fossil in the bedrock a few weeks ago in Livingston County. Anyone know what this could be? Edge of chisel for scale. Thanks for reading!

Took a quick road trip to a fossil locality in western New York over the weekend, a bit south of Rochester in the finger lakes region. Amongst the usual fossils I dig up at this locality I found a very well preserved gastropod that was larger than any I have seen in my time collecting. I was hoping someone could help me identify the species. Thank you! Took a field picture in case I destroyed the fossil while trying to grab it. It popped out after a long and slow excavation. After washing the detail is much more visible, including possible predatory boring marks? Is this the fairly common Naticonema lineata? If so this is probably 4x larger any I have found perviously. Bonus Eldredgeops trilobite that I found on this same trip, needs some minor repair work.
