An Amazing Agnostoid Arthropod
piranha posted a topic in Partners in Paleontology - Member Contributions to Science
An amazing agnostoid arthropod was recently named in my honor. The Great Cambrian-Ordovician trilobitologist: John Taylor has bestowed Lotagnostus morrisoni upon yours truly. Although the Agnostida have long been classified among the orders of trilobites, because of a number of key differences, they are currently excluded and regarded as a closely related sister group to the polymeroid trilobites. In any event, the Agnostida will always be inextricably associated and studied in conjunction with the Trilobita. I'm very grateful to have the privilege to share this 'Lucky' Lotagnostus here at TFF!

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.
