During my visit to the Rickard Hill Road site I lucked out and found this trilobite in a slab. I think it is enrolled but I’m too scared to prepare it because I will probably destroy it by accident and I only found one trilobite. Anyone know the species?

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 ;

Sorry, the quarter was all I could find for a scale reference. My 8 year old spotted this in an area with lots of small Devonian fossils (crinoids, etc.). I thought this looked a bit like a portion of a eurypterid, but I am very inexperienced, and would not be surprised to find that I am waaaaaay off base. Any help with an ID would be very much appreciated! Thanks!

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.

I collected today in an exposure of the Helderberg Group in NY. The Helderberg Group is Lower Devonian, and rich in marine fossils. We found this in the mine and could not come up with any kind of ID. It is possibly part of a horned coral? Or a brachiopod? Please let me know your thoughts. I can also provide more photos if necessary, I tried to capture the different angles. It is an interesting thing.
