I wonder if this fossile in a shale is a graptolite or a nautiloid. The length is about 3cm, age middle ordovician, in the Elnes formation. The place has many graptolites. Pict. 1 Pict. 2 I also found this 1,5 cm long specimen, which seems to be a nautiloid?

Last summer I visited Helgøya, a place north in the Oslo-field, and found this rock at a site I believe is middle or late ordovician. No other well preserved fossils was possible to find at the site. It is very fragile, so didn't break up the whole rock, but some parts fell of which have clear patterns. It seems the whole rock have some kind of bullet forms inside. Anyone have an idea which kind of animal it is? Pic.1 Pic. 1 Pict. 2: Pic.3 Pic. 4 Pic. 5 Pic. 6: Pic. 7:

Thought I'd post this interesting new paper which describes Australia's largest species of trilobite so far documented. Described are 16 species of trilobite, including two new genera and five new species, all from the Amadeus Basin in the Northern Territory. One is even named in honour of my father and I, Iridis schoonorum LINK

Bug du jour - Please help me identify my trilobite, One-eyed Jaques
GeschWhat posted a topic in Fossil ID
I purchased this beautiful pile of poo pellets, and the matrix contained this little hitchhiker. Since I know next to nothing about trilobites, I was hoping for an assist. He dates from the Middle Ordivician (Llandeilian), and was found in the Traveusot Group (Angers), in La Meignanne, Maine-et-Loire, France. I don't know if the second photo is more of Jaques or just another trilo-bit. Thanks for indulging me. Yeah, I'm digressing.....- 18 replies

From the album: Middle Ordovician Trenton Group in New York

Hello everyone! So a while ago I collected a couple of rocks while fishing up near Plattsburgh, NY. These rocks were from the Ordovician Trenton Group and contained a variety of organisms including inarticulate brachiopods and corals. More importantly though, were the variety of trilobites. In one of the rocks I found pieces of Isotelus, Cryptolithus, and Ceraurus. I was looking at a small piece of that rock yesterday when I noticed a strange little fossil. It was a tiny, spiny free cheek of a trilobite! It looks very similar to Meadowtownella trentonensis although it could b

Can please someone help me? I found this fossil from an middle ordovician place. Could it be a horncoral or a foram with a spiralform? The specimen is about 2 cm in diameter, some parts hidden in the stone. Any help very appreciated.

It was a beautiful 53 degree day today and I decided to take a 155 mile round trip to Oregon, Illinois. The purpose of the trip was to collect a road cut that exposes the Middle Ordovician, Platteville Group / Miffin member fossils. @connorp was nice enough to give me the location to this 1/2 mile collection site in Ogle County. I had fun checking out this area, but it will probably be my own time visiting this site and not for any particular reason. There is plenty places to park along the road, but this area can be tricky for people who are not sure-footed and children, as the s

Good morning everyone, Few weeks ago I found this interesting imprint in limestone erratic boulder, it was found in Klaipeda district Western Lithuania. The fossil is 2 cm length, I would think it belongs to worm or maybe sea cucumber. Any idea? Best Regards Domas

I found this several years ago in Kentucky near Maysville, which, based on this map, is in the middle to upper ordovician. It was probably around 50 feet down. All I have is the tail. Probably not enough to identify, but any information would be appreciated. I couldn't find a measuring device, but I will post a picture with one as soon as I do. It is about 8 1/2 inches long, or 26 1/2 centimeters. Map is upside down. I have the fossil on hand for any clarification/questions.

First off, I don't know anything about paleontology. I found this fossil in Nicholas county Kentucky. It was about at the C in NiCholas county on the map. Sorry it's upside down, but Nicholas is 2 above bracken, assuming picture orientation. The fossil was 6-10 feet down. The first layer of fossils went down about 5 feet, maybe more, and we're tan and sandy. Below this layer was a gray layer, and this was several feet into that. Also, don't have enough file space to do enough pictures for inches, but it is about 11.5 centimeters long, or 4.53 inches.

Hello everyone! I've been examining a fossil I found a short while back and wanted to try and confirm my suspicions that it is a Orthoconic Nautiloid. Interested to hear some opinions from those more knowledgeable than I. So far I've been struggling to find good resources describing the different species found in this formation, it seems the work of John Laurie should possibly be my focus. The diameter of the possible siphuncle seems unusually large and positioned in very close proximity to the outer shell. I seem to remember reading something about the siphuncle moving closer to the outer she

Rhynchonellids are hard to identify by exterior morphology as they often need to have their internal structures visible to be sure of an id. However if you know the faunal lists from a specific area, you can reduce the candidates considerably. The specimen here has 22 costae with 4 on the fold and thus, at this size must be one of two species, Rostricellula minnesotensis or Rhynchotrema wisconsinensis. The only completely safe way to differentiate between the two is the presence or absence of a cardinal process in the brachial valve but this is not possible here. However, Rostricellula usuall

Need help with identification of this trilobite cephalon from Silex, Missouri (Middle Ordovician, Decorah Group, Bloomsdale Fm?) I'm thinking Eomonorachus intermedius? @piranha @GerryK Scale in mm I also found this hypostome in the same spot. Not sure if it's the same taxon.

Hi TTF! Since I am now going to present my science fair at the Ontario regionals, I have decided to add a few new displays to it. Right now, I am working on a model of the Earth during the middle Ordovician, when Pseudogygites Lantimarginatus lived. I have searched the internet for pictures of the middle Ordovician Earth, but each one is slightly different. For example, the location a Siberia changes with almost every map. I assume this is just because the different maps were made during different eras or by different people. Does anyone on the forum know which is the most up to date image? Th
-
As with the adult this has more costae than any other brachiopod found in this formation. In this case 32. and 5 of them on the fold. The fold and sulcus are not yet very noticeable, as this species only develops a noticeable fold as it matures.

Orthocera Specimens 11" x 18" Morocco Data: Orthoceras ("straight horn") is a genus of extinct nautiloid cephalopod endemic to Middle Ordovician-aged marine limestones of the Baltic States and Sweden. This genus is sometimes called Orthoceratites. Note it is sometimes misspelled as Orthocera, Orthocerus or Orthoceros (Sweet 1964:K222). Orthoceras was formerly thought to have had a worldwide distribution due to the genus' use as a wastebasket taxon for numerous species of conical-shelled nautiloids throughout the Paleozoic and Triassic. Now, Orthoceras sensu stricto refers to O. r -
Sorry this report is late, but I wanted to wait until prep was complete as I always show unprepped finds lol. Back in May, Laura and I made an impromptu trip to Grant County Wisconsin for some trilobite action. We had spent nearly five hours hunting with only partials and some hash plates uncovered. I decided to sit in the middle of the site and take a break and let Laura search. Being bored, I started to pick up pieces of rock and brush off the dirt and broken pieces of matrix. To my utter shock, I brushed off some dirt and saw a cephalon emerge, with what looked like thoracic segments. I fin

I bought this from a store in my area, it is labeled Licuites Iii. I think it's real but I'm weary, especially since there was a "Made in China" sticker on the back. If it is real, is the ID correct? on the bottom it appears that some fossils have been cut through, and on the end part of the orthocone there is a faint circle in the rock, suggesting it's three D. Assuming it's real, can it be prepped? Thanks for any information!
