I was working at my desk today when one of my fossils caught my eye. I picked it up and thought that looks like a Tully Monster, but a quick check on the internet and I realized too small and not my geological time period, the Tullimonstrum belongs in the Pennsylvanian period. 300 million years ago, too young, there you go Illinois US. So I’m thinking a part of Eurypterid, or sea scorpion, they were around during theSilurian. What do you all think?

Fossil forum, This is another specimen from the Leighton Fm. I had two possibilities, Lingula scobina and L. lewisii, which I found mentioned in this paper https://repository.si.edu/bitstream/handle/10088/14399/1/USNMP-45_1985_1913.pdf, and which I further researched. The main problems I have with these two species are that L. scobina has different surface sculpture, and L. lewisii is an English species. Any further guidance or suggestions? Here are some pictures of it (internal mold on the left, external on the right):

Fossil forum, I recently found an interesting fossil. I was thinking coral or bryozoan, but was unable to identify it correctly. It is from the Leighton Fm Maine (again), which is Silurian. Any help would be greatly appreciated. Here are some pictures of it:

Fossil Forum, I recently found multiple brachiopods that I believe are in the genus Salopina, moved from Orthis, and of the same species. I found them in the Leighton Fm, Maine, which is Silurian. I was wondering if anyone could tell me what the species was, and also if anyone had any literature on this genus. Here are some pictures of them (internal molds are on the left, external on the right):

Hoooooooooooorrrrrrrrrrrraaaaaaayyyyyyyyyyy!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Here we are at last, into Adam's Silurian. Thanks for looking. First up is the Lower Silurian or Llandovery and I begin with a problem. I posted this one incorrectly in Adam's Ordovician as it had got it's label muddled up with an Ordovician Favosites I had that has vanished in the move here, but is being replaced by kind forum member @Herb Anyway, this, I remember now I've found the correct label, is from the greenish Browgill Formation, part of the Stockdale Group from a cutting near Skelg

I'm excited to get into fossil collecting, but before I spend money on gear, I'd like to be able to make an informed decision. The fossils I'd be collecting are from the Silurian age Racine Dolomite. I know that Estwing tools are generally considered the best, but other than that, I am completely unsure as to which hammers and chisels would be most appropriate for breaking these apparently very hard rocks, or even how to go about using them. I know a spot on a friend's property (by the Milwaukee River) where there are a bunch of Silurian rocks piled up, so I don't think access will be a huge p

Americaspis americana, dorsal shield endocast from jawless fish, Silurian in Pennsylvania

Featured is a beautiful specimen of Calymene breviceps from the Waldron Shale. Despite this species being a somewhat common trilobite of the Waldron Shale, specimens of this quality are hard to come by. Specimen is 1" on matrix measuring 3.5" x 4.5". Collected and Prepared by Ken Karns. -

From the album: The Waldron Shale
Plate with two specimens of the Crinoid Eucalyptocrinites elrodi (Hall). Plate measures 10" x 7" with crowns measuring approx. 2.5" in length. Specimens of this quality are exceedingly rare in the Waldron. Note the one specimen complete with root system. -
Any ideas on this partial lichid? Sugar run formation. Measures about a cm. Also on the fence on the other cephalon. Proetid? Thanks for any help.

These are two fossils of the same species collected at the Long Pond Road Site along the Erie Canal in Greece, New York. They are from the middle Silurian Rochester shale. These were collected last winter, and I have since been unable to identify them. Both are no greater than 3cm in length. Some interesting fine detail is visible on the first specimen. The American dime is 1.8cm in diameter.

This is a fossil I collected at the Long Pond Road Site along the Erie Canal in Greece, New York. It is from the middle Silurian Rochester shale. Some interesting perpendicular lines can be seen along the edge of it. I have looked for other fossils similar to this one and have found nothing. The American dime is 1.8cm in diameter.

Hi all. I have this specimen i bought fra a dealer in western europe It's from the Lesmahagow in scotland. I bought it as a Slimonia, but was later advised on facebook that it's in fact a ceratiocaris. What do you guys here think? I'm pretty convinced it's a ceratiocaris. What confuses me is that the dealer is quite experienced and he collected it himself decades ago, and got it id'ed by the museum in Edinburgh

Last week we took a ride to Lake Michigan to do a short search before the weather turned bad. The previous day had strong winds with large waves and I thought we might find some interesting things. We found plenty of Favosites, Halysites, and Rugose corrals as well as some of the other usual finds. The one unusual find was what I believe to be an internal mold of a Pentamerus oblongus brachiopod. I don't find many brachiopods and as such I'm not 100% sure on my ID. Please confirm or correct. Thanks in advance. Jim

Hey Folks, I specialize in the Middle Silurian Waldron Shale formation. However, I have many other North American Paleozoic invertebrates from many classic sites. I would be happy to exchange this material for any good Waldron Shale fossils, prepared or unprepared. I'm located in Ohio. Drop me a line and let me know what you have and what taxa you may be interested in. Look forward to hearing from you. Note: If you would like to exchange Waldron material you have for Waldron fossils I have...we can do that. For instance, if you have unprepared Waldron fossils I c

Good morning. In the process of prepping/detailing this calyx I have misplaced some of the documentation. I know the crinoid is from the Waldron shale, Niagaran series in Waldron Indiana. Original purchase date was 1982. I have lost the actual name of the species, help please.

I am the president of the Oxford County Mineral and Gem Association, but I am at least as interested in fossils as minerals. Maine is of course not known for fossils but there are some in the north. After living here nearly eight years, my wife and I finally ventured in that direction to see what we could find. The attached file was prepared for the OCM&GA newsletter. Hope you enjoy.

The weather is exceptional in southern Ontario, these days. 25 degrees C! That’s 77 degrees Fahrenheit to my US friends and for here in November it is exceptional! We decided it was a great day to go to Big Bay which is situated on Georgian Bay between the Owen Sound and Colpoys Bay a beautiful place down a gravel road; it can be busy in the summer but we knew today it would be quiet. The trip was purposeful because I know it is just full of water washed fossils and I wanted to post pictures of what is there. I wanted to show you all how prolific the Silurian Ocean was. I also included a co

So i might soon be heading to a silurian site. It has shells trilos crinoid stems. But i would really want to find a complete crinoid. Any tips how? Split rocks open? Look in areas where theres alot of crinoid stems?
