The Devonian period is known as "The Age of Fish", but could also be known as "The Age of Brachiopods." In the Early / Lower Devonian, brachiopods reached the height of their diversity towards its end in the Emsian. We see the ancestral groups occurring, lingulids, craniids, orthids, protorthids, pentamerids, rhynchonellids and strophomenids, as well as the later successful groups we have seen before such as atrypids, athyrids and orthotetids, plus the rise of spiriferids, spiriferinids and productids and the beginning of the terebratulids. By the end of the Devonian , several of these groups are extinct or severely reduced in importance and brachiopods never quite recover. Also, the Devonian is the last time we see trilobites with such variation, large sizes and numbers and orthocerids too are much more uncommon after the rise of the goniatites. The massive tabulate coral reefs also disappear after the Devonian. Fascinating period and I hope to share some of its wonders with you. Equally, a lot of this is rather new to me, so I would be very grateful for any assistance, corrections or further information on my specimens. Thank you. The Early Devonian epoch is split into three stages, so let's start with the first of those, the Lochkovian, that began about 419 mya and finished roughly 411 mya. I have been sent a nice selection of brachiopods from the Kalkberg Formation, Helderberg Group by the Mighty @Misha, mostly. But the kind gentleperson also sent me this fascinating little bryozoan hash : It is dominated by fenestellids, which is usually the case in the Devonian, but other orders sill occur. These ones, I think, are Fenestella, but there are so many species in the formation that I wont take a guess as to species : Not sure what this one is ;

I would be very grateful for any help regarding ids of these tiny oddments found in a matrix piece from the Early Devonian Helderberg Group, Kalkberg Formation of the Rickard Hill Road cut, Schoharie, New York state. The piece contains four really nice brachiopods, the horn coral Enterolasma strictum and a lot of tiny crinoid ossicles. Perhaps, in strict alphabetical order, @Darktooth @Fossildude19 @Jeffrey P@Misha or @Nautiloid might be able to throw some light on them? Thank you. This first one seems to be encrusting along the growth lines of large, flat specimen of Discomyorths oblata. Could it be a cornulitid of some sort? About 2.5mm long. This first picture seems to show it as pointy, but if you look, the wider end is actually sort of horseshoe shaped ans seems to have an opening infilled with sediment. It seems to show growth lines. The second specimen I thoght might be a tentaculitid, but now I'm leaning towards a gastropod? Note the very fine striations. About 3mm. What about these, please? Some are clearly stemmed echinoderm ossicles, but is that a tiny lingulid. Are there ostracods? These are all only a millimetre or two across. These last two may be burrows? A white one: And a darker one: Finally, tis nice to know they had McDonalds in New York back in the Early Devonian. Thanks to everyone for looking and for any assistance.

Hello! Just wanted to post a few of my recent find from the Gilboa and Schoharie areas - would love to learn more about them, and appreciate any info! In the image of the light yellowish color rock, I am curious if that may or may not be stromatolites, or just a layer of chert? That was found in Schoharie near the quarry - Thank you! From Gilboa area

Hello all! Excited to be part of the forum and share some of the finds I have come across soon I am looking to get out this long weekend to Gilboa and wondering where there might be some good access points to the Schoharie Creek there? I saw in a previous post a few years ago that access on Stryker Rd was temporarily closed, and curious if that is still the case, and if that is the same place that on Google maps looks like a parking lot near the bridge by the dam? If so, wondering where some other points would be good to look for plant fossils as I have yet to discover any of those yet in my travels. Many thanks in advance and hope you all have a great weekend and best of luck hunting! - Sarah

Hi folks, This is my first attempt at id'ing small braciopods and coral. Could you please give some input on if I am wrong or right. They are all from the Devonian period from the Schoharie NY roadcut. The last corals are from the uppermost section of the Becraft limestone.

I know this trip happened a while ago, but I’ve been pretty busy as of late finishing up the school year and such and haven’t had a chance to make a trip report. Hopefully y’all find this interesting.

Gastropods: Diaphorostoma depressum Platyceras spirale? Tremanotus profundus (very flattened specimen).

I’m almost done prepping this gastropod I found a couple weeks ago at the roadcut along Rickard Hill Rd. in Schoharie, NY, but I am unsure of the species. It is from the Lower Devonian Kalkberg formation.

I found this fossil last weekend at the road cut along Rickard Hill Road in Schoharie, New York. It is from the Lower Devonian Kalkberg formation. The surface has no texture at all. The fossil has a thickness of about 1mm. Originally I thought it was less than 2 inches long and wide but I was able to prep out the rest of the fossil due to the softness of the matrix. It is about 3 inches wide and long.

Uncommon trilobite from the Kalkberg Formation

Kosovopeltis pompilius pygidium Lower Devonian Helderberg Gr. Kalkberg Fm. Rickard Hill Roadcut Schoharie, New York Collected 5/31/20 -
I recently broke open a few slabs of rock I took home with me from Rickard Hill Road in Schoharie the last time I was there. The rock was very crystalline and hard to break and there weren’t a ton of fossils inside. I did manage to find a couple of trilo-bits that were very well preserved and very detailed. One of these bits I’m having a bit of trouble identifying. I’m almost certain it’s a trilobite pygidium but it looks like nothing I’ve ever seen before. The great preservation makes the details of the shell stand out. It is around 1cm long and wide.

Today I was able to get out to the outcrop along Rickard Hill in Schoharie, New York. I didn’t find a ton of interesting things because I was looking in a more crystalline layer of the Kalkberg formation that had less abundant fossils. I found a handful of nice orthid, spiriferid, and atrypid brachiopods and one fenestellid bryozoan. Next time I go I’m going to try and get into a different, more fossiliferous layer because the crystalline rock is hard to break and when it does it breaks randomly, often damaging the fossils.

Hey everyone, I am curious if this is a placoderm armor plate. It is from Schoharie quarry, NY. Thanks.
-
This was collected in the Schoharie Creek bed approx. 5 minutes downstream from the Gilboa fossil forest in Schoharie County NY. The fossil was originally encased in limestone, I used 50% solution of Muriatic acid and water for preparation. I tried to look up some information but couldn't find anything exact, any help would be appreciated.

Hello, I found this forum a few weeks ago while searching for information on fossils. It seems like a very informative and friendly place so I joined today. My name is Paul, I live in Oswego, NY (N/W of Syracuse, NY), I'm 50 years-old and am extremely new to fossils and fossil hunting. My family and I will be making our first fossil hunting trip this Saturday to either Tully, NY or Schoharie, NY (I still haven't decided on the location).

My wife and I are on a short trip through south eastern New York State, in the Catskill Mountain region. We had a more adventurous trip in mind but after some recent car trouble we didn't feel quite as adventurous as we did a week ago. We stopped today at a site on Schoharie Creek, a bit south of Gilboa. The heat and humidity kept us from spending more than a half hour at the site today, but we plan on going back tomorrow morning when it will be somewhat cooler. The river tumbled stones were mostly eroded, and I didn't bring my hammer down to the beach crowded with swimmers, but we did make one find worthy of bringing back to the motel. Leila usually makes the best finds when we're just scanning the ground, and she came up with this worn but still attractive horn coral. I love the way it's still attached to the matrix. It almost looks like it's been prepped: The same rock also shows off some nice specimens of what appear to be tube worms. Despite the heat we're enjoying our trip so far, and we're very happy with our motel except for one disturbing problem. Clinging to the door inside our lovely room is a five-foot-long mirror, and I am periodically startled by the strange old man peering at me. What's he doing in my room?! Mike
