Hi everyone, I have some trilobites I need help with identification on. I acquired these several years ago, so I am not entirely sure where these trilobites were found and can only suspect. The first is a trilobite that I believe is from Morocco. It is around 6 cm in length and 3 cm in width. The other two are Agnostid trilobites that I believe are from Utah. I was wondering if it was possible to limit each down to a genus. The darker one is 6 mm in length with a thorax around 3 mm wide. The lighter one is 7 mm in length with a thorax around 3.5 mm wide. Any help is appreciated. Thanks! IMG_5098.HEIC IMG_5100.HEIC IMG_5102.HEIC IMG_5104.HEIC IMG_5108.HEIC IMG_5109 2.HEIC IMG_5111.HEIC Whoops! I just realized I attached the first trilobite's images as files instead. I'll try to upload them as images instead in a reply.

Hello for all. It has been a while to leave a post here! I am currently in Burlington, VT as a UVM student. Before the end of the summer recess (August 18), I traveled to northern Vermont consulting some articles about Cambrian and Ordovician formation located in Highgate Falls and South Hero. In this post, I will just talk about one trip to Highgate. I left my dorm around 11 a.m., and I get the Higate Falls near 1 p.m. After straying about 3 hours, I finally realized that the outcrops described as fossiliferous in the article are located in the private land. Thanks to my student ID card, the landowners welcomed me I could not hunt fossil around the Ordovician formation (Highgate Formation; Upper Ordovician) because the cliff was really steep and seemed very dangerous. It is on the left side of the picture (Red line). So, I just focused on the right side (Yellow line) that is Gorge Formation (Upper Cambrian, Upper Sunwaptan Stage, 492-491 MYA). Below is a photo of the Gorge Formation I found some trilobites and brachiopods (not on this post), but I have no clue about their scientific name even though I checked my article... I would appreciate if you correct the wrong scientific name 1. Lotagnotus americanus Billings, 1860 2. Geragnostus ( Micragnostus ) bisectus (Matthew, 1892) (Shaw, A. B. (1951). The Paleontology of Northwestern Vermont. 1. New Late Cambrian Trilobites. Journal of Paleontology, Vol.25, No.1, pp.97-114.) 3. Librigena.

Hi everyone, I recently got this small Agnostida from the Late Cambrian (Sandu Formation) of Guole, Guangxi PRC. I have no idea to what species this little "two-headed" bugger belongs. Anyone can help? Thanks Thomas
