Hello, Roommates! I received this little trilobite as part of my Secret Santa package, and, though i know the eyes are missing, and parts of the pygidium etc., am rather fond of the little fellow. The label with it said Illaenus americanus and it was said to be from the Galena Limestone, Upper Ordovician nr, Postville, North East Iowa, a quarry or a roadcutting. Now the first thing I discovered, and please correct me if I'm wrong, is that the name is no longer valid and this is now Thaleops laurentiana. And on looking closer, it doesn't seem to be it at all. The lack of axial furrows and general effacement led to me to think Bumastoides sp. so i then read up on the paper https://www.researchgate.net/publication/257656692_A_systematic_revision_of_the_Upper_Ordovician_trilobite_genus_Bumastoides_Illaenidae_with_new_species_from_Oklahoma_Virginia_and_Missouri?enrichId=rgreq-42948ac4406fefc77dead768950eae0b-XXX&enrichSource=Y292ZXJQYWdlOzI1NzY1NjY5MjtBUzo5NzE0MzExMzEyNTg5NUAxNDAwMTcyMTMxNjE4&el=1_x_2&_esc=publicationCoverPdf and so on. I also discovered this (second item down, left hand margin : http://www.robertcharleswolf.net/newsletter942186.htm So it could actually be Maquoketa Formation, Elgin Member. The specimen seems to have 10 segments in the thorax so I'm thinking B. porrectus or B. beckeri. Any help greatly appreciated, here are a few photos:

Hi again! I have another unidentified fossil from the Billings. It is a brown or dark yellow coloured streak. I think it must be some type of ichnofossil. To me, it reminds me of some fossils of Diplocraterion. It could also just be a streak made from another mineral, such as calcite. It is preserved alongside one almost full-length crinoid stem impression and one 3 dimensionally preserved specimen of the aforementioned animal.

Ok, let me explain this title. I was out for my second hunt in the Billings Formation yesterday and found this fossil. There have been many fossils that I could'nt exactly identify, but usually I have some inclination or hypothesis about its identity. This is not the case here. I am at a total and complete loss as to what this thing could possibly be. It is circular and ribbed. The first thing I thought when I saw this was "human fingerprint". I have put my own finger in the picture for scale. Looks like somebody stepped off the path in the Ordovician!

Another unidentified fossil from the Billings Shale Formation! This time, it's some kind of spiral shaped fossil. There are actually three in this one stone, and many more in other places, so they are fairly common. This fossil has a definite spiral shape, unlike the orthocone cross sections. Right now I think they are either some type of Gastropod, or a coiled ammonoid nautiloid cephalopod. Any ideas? I appreciate your help!

Ordovician Trilobite
DatFossilBoy posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hello, I saw this trilobite on a french auction site. It is sold as restaured but I don't know which parts are restored and which ones are not. Also looks kind of filled and flat, normally these species have details and are not that orange. Can somebody tell me more? Does it look authentic to you? Regards, Thomas

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.

Brachiopods, perhaps rhynchonellids most of all, are notoriously hard to identify without their internal features exposed. However, if you know the formation and rough location and have faunal lists it can be possible. Rhynchonella ainsliei, for example, has 26-34 costae with 5-7 of these appearing on the fold. This specimen has 30 and 5 respectively and is the only species that has so many found in this formation. It also has the correct shape and size to support the match.

OK, I think I am kind of bending the rules on what constitutes paleo reconstuctions here. For the past few months I have been doing work and research for a Trilobite (Pseudogygites Lantimarginatus) themed science fair project for school. Now that it is February, the actual presentation of the project is approaching quickly. Since I enjoy baking and arts and crafts, and because I am a firm believer in the effectiveness of bribery, I wanted to incorporate something extra into my project. After hours of scouring the internet for all things Trilobite, I found a template for these Trilobite shaped cookies. After one night of hard work and over fourteen nights of doing nothing, the cookies are finally finished! Enjoy! (The pictures)

An Orthoceras fossil from Beckham's Barn. Any idea which species it is?

Found this little guy yesterday in the Ordovician Carter's limestone, middle TN. Just a glabela and one eye, but clearly something different than the typical fossils from the Carter's. I'm thinking it may be Raymondites sp.?

Hello, Today my Ordovician Asaphus Raniceps trilobite has arrived in the post and I am really happy. I bought it on an American auction site for litteraly nothing. It is 4,5 cm and is missing the left eye, the other one is complete but its missing the orange skin-armour of an Ordovician trilobite. This is the one I would like to get prepared( did a topic 5 days ago) because there is dirt/ stone on the back and it could do a good clean job. Hope you like this post, It is my 3rd trilobite and 1rst Russian one. Thomas

Greetings again TTF! The Billings formation is just filled with stuff that I can't identify! This time, I have found some glossy, cylinder-shaped things in the Billings Shale. I know that conodont elements are known from some parts Ontario and Quebec, but I think that it might be a belemnite as well. They seen to be associated with crinoid stems, brachiopods, and one Pseudogygites Lantimarginatus pygidium. They are each roughly one centimetre long. They are in the centre of the first picture and the second picture.

Hello everyone, I recently purchased an Ordovician Trilobite on a auction site. It really needs some preparation,and it would look so stunning. I am looking for a professional expert in fossil preparation who knows what he is doing, I would like it for him/her to be in Europe because outside Europe the shipping is very expensive... I would be shipping it to the preparator,he would prep it and then I would pay him whatever the shipping costs to ship it back to France.(With an additional little ammount to say thank you.) If you are interested,contact me by private message, and I will tell you all the detail you need. Really appreciate it and this prepped trilobite would look amazing in my collection. Thanks,Thomas

It's a UTF! I found this in an exposure of the Ordovician aged Billings Shale Formation. It's clear that it is a Trilobite fixigena, but I was wondering if a Trilobite genus can be identified from one alone? I have found three distinct forms of Trilobite in this formation: Pseudogygites pygidiums, Isotelus fragments, and Triarthrus head pieces. Any ideas? Thank you very much!

I found this weird looking fossil on a trip to an exposure of the Billings Shale formation of Ottawa, Ontario. This formation is late Ordovician in age. It looks either circular or spiralish in shape. Does anyone know what this might be? Crinoid stem? Ammenoid? Nautiloid? Gastropoda? UFO Imprint? I really appreciate it!

Hello, I collected this gastropod from a quarry along the Illinois/Wisconsin (USA) State line. Can anyone assit me with the identification? From the attached ID chart, I think that it is Loxonema. Thanks! Greg

I just pulled this out of a box of old fossils, but I'm not exactly sure where I originally found it. I think it is from the Carter's limestone, middle Ordovician, in the Nashville, TN area. It has a similar shape and size (~2 cm dia) to Hindia, but I have not seen anything else with this distinctive pattern of parallel criss-crossing ridges. Any ideas? Thanks
