I didn't know what these were called until now. You may see Itagnostus interstrictus called Peronopsis interstricta. They are synonyms for the same species. Generally, older texts have Peronopsis interstricta and the newer ones have Itagnostus interstrictus. 2 Each dot is 50,000,000 years: Hadean............Archean..............................Proterozoic.......................................Phanerozoic...........

Your excitement is written all over your face. Love the selfie pic. Can’t imagine how heavy it was to carry out. Hope you didn’t have to hike too far out. What are the measurements on it? The Mancos Shale does have some really nice Ammonites!...and definitely why I never stop looking for them. I keep a woven seed sack and some heavy pillow cases at the bottom of my bag for just such occasions...slinging a beast like this over your shoulder is a bit easier than trying to hold it while hiking. The steinkern is solid calcite and pretty darn heavy, luckily I was not terribly far from the truck. Measuring at a whopping 18 inches, Coilopoceras inflatum was a Turonian beast, and you're right, at this size it could almost fit into Terry Dactyll's collection.

Thought to be a blind, parasitic trilobite, its name is Itagnostus interstrictus. This trilobite is from the Wheeler Shale in the House Range, Utah and was alive during the Middle Cambrian. While this was found in North America it can be found in many locations across the world. This makes this species an important biostratigraphic tool for correlating the same rock age across the globe. Measuring in at a gigantic 8.5mm, this is almost double the average size of a Itagnostus interstrictus. I aquired this while splitting shale near the U-Dig quarry in the House Range. The trip report can be found here. This is the biggest I have found in the several trips to this area. While Itagnostus interstrictus are frequently overshadowed by the world famous Elrathia kingii, this is their time to shine and who better to lead it than this behemoth. That is a nice very large example of the species. However, this is the first I have heard of agnostid trilobites being parasitic. Do you have a reference for that? What did they parasitize?

However, this is the first I have heard of agnostid trilobites being parasitic. Do you have a reference for that? What did they parasitize? Don I found it was proposed to be parasitic. I thought it was interesting. This paper (http://www.ijournalse.org/index.php/ESJ/article/download/114/57) mentions that maybe they were parasitic. That's why I phrased it as "thought to be". This paper (https://onlinelibrary.wiley.com/doi/abs/10.1111/1475-4983.00080) goes further in depth into the subject but finds the idea improbable as they'd have to be parasitizing anomalacarids. "Bergstrom's suggestion about parasitic habits is intriguing. It was based upon the resemblance of highly caecate agnostids to living parasitic copepods with a comparably well-developed system of digestive glands. The host was not suggested. Some caecate (scrobiculate) agnostids are extremely abundant and widespread globally (e.g. Glyptagnostus reticulatus, see Kobayashi 1949)." The article they are refering to is "Organization, life and systematics of trilobites" by Jan Bergström, 1973. I haven't found a website with free access to post here. As far as I know, it hasn't been concluded out of the question whether or not they could have been parasitic or not but it's interesting so I threw it in there.

Pterosaur Posted November 20, 2018 Share Posted November 20, 2018 This is a rib I dug out of the Hell Creek formation back on September 17th in Montana! I did the majority of prep work early this month due to a new job I started around the same time I got back from the trip. Another Fossil Forum user, Troodon, was actually there when I dug it up, and he assisted with the dig. (Hopefully this still counts!) I had to take it back in about a dozen pieces in order to get it on the plane. The rib is well over 3ft along the curve, and most likely comes from one of the following: -Tyrannosaurus rex -Triceratops horridus -Edmontosaurus I haven't gotten a definitive ID on it, but based on the head of the rib my guess is T-rex? If you have any different ideas please share them! Date of discovery : 9/17/2018 Scientific or Common name: TBD (If I had to guess it’d be Tyrannosaurus rex) Geologic Formation: Hell Creek Formation State found: Montana Photos of find: Dig and initial prep work: Prep in progress: (I know it's not wise to hold it slung across my shoulder, but I wanted to convey the enormous size! I'm 5'3 tall for comparison) Prep completed (still needs a little crack fill and some buffing but it's done for the most part): 13 "I am a part of all that I have met." - Lord Alfred Tennyson Link to comment Share on other sites More sharing options...

I think we can all agree that there was substantial prep work involved to reassemble this puzzle so it looks like you have a strong entry for VFOTM this month.

See if you can obtain a more precise ID from @Troodon or @jpc for a better identification in your submission (the two people that come to mind for a find such as this). You can start by reading the numbered rules in the first entry that started this post and making a "formal" entry with all of that information (repeated here): *******Please use the following format for the required information:******* Date of discovery Scientific or Common name Geologic Age or Geologic Formation State, Province, or Region found Photos of find:(if prepped, before and after photos, please.) Limit - 4 photos, please. If you get a more precise ID to later to make a better "Scientific or Common name" you can add that later and I'll merge it in.
