Trilobite pygidium broken before fossilization?
Raistlin posted a topic in General Fossil Discussion
So while prepping this pygidium I started to notice stuff was missing. More so than the normal. This pygidium seems to have split in half. Could it possibly be predator leftovers or something similar? Adding prep pics to see what I was seeing and show I did not cause yhe damage. -
Unknown possible pygidium. Joliet formation. @piranha

Hello again everyone, sorry for the delay between Part 1 and Part 2. I went through some more material from DSR and I've made some pretty awesome finds. I might have enough specimens for a Part 3, but I still have to go through more material. The same goes for the Penn Dixie part, I've barely touched it yet and still need to photograph the finds. To kick Part 2 off, here is my best DSR find yet! A nearly complete (unfortunately disarticulated) Echinocaris punctata!!! My kitten Indy for scale The Echinocaris has one of the spikes on its t

Used a sewing needle and acid (water and 45% vinegar mix) to prep this due to size. Never used to technique before and finished it off with Paleobond. Did it come out ok? I had no choice but to Paleobond as I loosened a part of the cheek spike while prepping. The pygidium is 8mm long and 10 mm wide. Mississippian Golconda formation.

Hi everyone, I am very new to fossil hunting and am hoping to find some trilobites. I am located in along Lake Huron in Ontario, Canada on a rock formation from the middle Devonian period. I broke open a rock on my second trip and found this but I am not positive what it is. I think it could be a fossilized pygidium from a trilobite but i am really just guessing. I have attached to photos of the fossil, if anybody could help me identify it or steer me in the right direction that would be greatly appreciated. Thanks.

At first I thought this was the Trochurus pygidium. I've been looking for for a few years now, but since it appears to have 6 spines instead of 4, not so sure. Maybe Ceratocephala? Sugar Run. @piranha

Moroccan Trilobite Scabriscutellum developmentally abnormal pygidium
Biotalker posted a topic in General Fossil Discussion
Something caught my eye at the cheap table of trilobites at a Moroccan vender at a past fossil show. There were several Scabriscutellum of mediocre quality but I bought two. You can see them here. I am pretty certain these fossils are legit. One seems to have to have a clear cleft in the pygidium. There is even a small overlap of one pygidial "lobe" over the other. This is the first time I have seen such a "dramatic" mutation. I would guess that it is far more likely to be a developmental issue rather then a genetic mutation. The cleft trilobite obviously survived to its current size just fine- 9 replies

This trilobite pygidium was found in a talus slope at base of Fossil Mountain in Western Utah. As you can see it is quite weathered. I found it about 25 years ago when my mom and I went back country driving in my Ford Tempo lol. That car went into a number of not car friendly areas haha. From what I know of area geology I believe it would be Ordovician in age

Hi - this is my first post to this group. I found this partial trilobite fossil this past summer in Ordovician limestone near Eganville, Ontario, Canada and I am hoping that someone here can help me identify the trilobite species it belongs to. This piece measures 3.5 inches in length by a little over 2.5 inches wide and I believe it is the pygidium and most of the thorax (so a little more than half of the full trilobite). Also, it has a little over 1/2 inch in depth, so it is not completely crushed flat. I would have much rather found a full trilobite - and I do have a full tri

Hi again! Found this trilobite cephalon today with what looks like a pygidium under the glabella. Not sure of the species yet, is this a pygidium that got preserved under the glabella or is this possibly the internal structure?

I recently broke open a few slabs of rock I took home with me from Rickard Hill Road in Schoharie the last time I was there. The rock was very crystalline and hard to break and there weren’t a ton of fossils inside. I did manage to find a couple of trilo-bits that were very well preserved and very detailed. One of these bits I’m having a bit of trouble identifying. I’m almost certain it’s a trilobite pygidium but it looks like nothing I’ve ever seen before. The great preservation makes the details of the shell stand out. It is around 1cm long and wide.

Unknown Rare New York Trilobite Pygidium Undescribed??? Lichid?
Kurufossils posted a topic in Fossil ID
Today on a hunt I found on of the most unusual trilobite pygidiums I've ever seen from new york and cannot find anything out there to compare it to. Unfortunately the site is imported material from an unknown quarry upstate so all I do know is that its from the Devonian of New York based on other material found there, unfortunately I cannot attach a formation to this one. Also its also fragile and a very partial piece thats unpreped, I think its a ventral display. This maybe a head scratcher so maybe the trilobite experts here can help weigh in on what this can possibly be. -
Good morning all! A couple successful days of collecting and to my amazement, two trilobite pygidiums!. My amateurish guess is Ameura missourensis? It was found in Kansas City in a Winterset limestone outcropping. When I looked closer, there is something I thought could be part of the cephalon or some other fossil in the second photo about 12:00? Not sure if I should pursue cleaning it (and don't know how )-thoughts appreciated! Bone

Hi forum friends. Cleaning out the back of my pick-up, I noticed this pygidium. It looks a lot like the eldredgeops I commonly find here but has a distinctly high ridge along the centerline. Could be just a molt that was "pinched" upward by the sides ? or possibly something different Cheers .... and thanks,

Do any of our trilobite experts know what this pygidium belongs to? It's Cambrian from Jingxi, Guangxi, China. It's incomplete measurements are 25 x 27mm. Help!

So the new house and work have keep me way busier than I had expect. I finally got around to getting my prep room set up for the most part and got around to starting some prep. Here's what I started with. Then the progress of getting it there. I had an oopsie as my engraver kinda got away from me doing some damage. Finally I finished it off with a clear matte finish to help stabilize it and make it pop against the matrix.

Hey fossil folks, I’ve been very busy lately moving into my new house and planning my wedding (8/9/19 is the big day) so I haven’t had a chance to report on a few recent trips. In the beginning of July I got some nice fossil hunting in...I went to Cole Hill Rd, DSR and Briggs rd but I’ll post the latter at another time if I get the chance. This is just a short and sweet trip report for Cole Hill Rd from Friday July 5th. I got out of work slightly early and made the quick 40 minute drive to the site. I hunted from about 545-8pm. I decided I would try

I found this pygidium the other day in the Silurian Racine formation near Chicago, wondering if any trilobite specialists can help with species ID? I'm thinking Illaenus ioxus (is that current nomenclature?)but not sure. Thanks for any help.

I just went through my bag of trilobits from this summer. Most are identified. I am getting better with time!! Here are a few Small pygidiums, all between 1 and 2 cm. These small non descript tails are hard for me to identify. If there are ones that stand out, let me know, and why you think so! That way I will know for next summer's specimens. They are numbered. Thanks, Mike

This morning I was going through a bucket if Black Cat Mountain matrix a friend gave to me. I found this nice negative of a large trilobite Pygidium. I wonder if some one might know the species. Thank you

Found in Arkona, Ontario Age: Devonian Size: about 18 mm/0.75 inches Any ideas?

I am finally getting most of my trilobite parts identified but still need some schooling on this pygidium: It was found in the Platteville/ Ordovician in SW Wisconsin. It is 4cm by 4.5 cm In addition, these two plates contain what I thought were just pieces of Isotelus, but the more I looked, the more I questioned my thoughts. Agree or change the ID? These plates are 12 inches by 6 inches. The asterisk's mark where the specimens are.
