From the album: Pierson Cove // Marjum Formation Fossils
Beautiful example of a puny species. Pierson Cove -
From the album: Pierson Cove // Marjum Formation Fossils
Marjum Formation, found this surface collecting after I got sick of working the insanely tough rock. -
From the album: Pierson Cove // Marjum Formation Fossils
Uncommon corynexochiid from Pierson Cove. Partial cheekless molt, but rare! -
From the album: Pierson Cove // Marjum Formation Fossils
Enigmatic fossil from the Pierson Cove. Less prevalent here than at the Wheeler outcrops we explored. -

PC Agnostid with dark anterior spines -
From the album: Pierson Cove // Marjum Formation Fossils
Nice brachyaspidion that split out at home, just needs a bit of work and it’ll be perfect! -

A nice, puny Jenkinsonia from PC prepped out by Jon! -
From the album: My Kinzers Formation Fossil Collection
The B-Side to the nice Wanneria I found with Dean Ruocco in 2022. This bug was in his collection until I traded him for it. Thanks Dean! -
From the album: My Kinzers Formation Fossil Collection
Here’s a perfectly articulated example of a once plentiful, now elusive Cambrian species. This is a puny bug, yet it is almost fully matured. The specimen measures less than just below one centimeter from cephalon to axial spine. Every delicate spine is in place, even the fragile axial spine! I was able to remove a thin layer of rock from atop the fragile cephalon without damaging the trilobite, making it one of my nicer finds this year. The bug is in the anti-Goldilocks zone of being just too big to focus under my hand magnifier to get the axial spine in focus along with the body, but you can still make it out in the photo. -
Paedumias yorkensis (?) juvenile
cameronsfossilcollection posted a gallery image in Member Collections
From the album: My Kinzers Formation Fossil Collection
Though I’m fairly sure P. yorkensis is currently invalid, this definitely isn’t Olenellus. About 4 mm, I believe the rest of this immature trilobite may be buried underneath the rock. I will prep it once I have the proper tools! -
From the album: My Kinzers Formation Fossil Collection
A nice, small Olenellus getzi waiting to be prepared. It’ll be around 2 cm when fully revealed! I’m This one should turn out beautiful, it’s certainly under there! -
Larval olenellid cephalon molt
cameronsfossilcollection posted a gallery image in Member Collections
From the album: My Kinzers Formation Fossil Collection
The smallest trilobite fossil in my collection, this shed cephalon is less than one millimeter in length. -
From the album: Pioche Formation
I split this beauty out last Spring, unfortunately the positive ended up crumbling away. The specimen is about an inch and a half long, a fully mature yet relatively puny example of this iconic species. -
From the album: My Kinzers Formation Fossil Collection
A nice articulated example of the iconic olenellid with a "honeycomb" pattern from the Kinzers Formation in Pennsylvania. The trilobite is nearly three inches in length, and could use a bit of prep on the cephalon and thoracic spines. This was acquired in a trade with @Dean Ruocco, who snagged the bug at a local fossil show. -
Hello, Could I get an identification for this fossil from the Cambrian of Yunnan, China? It was described as a "Chancelloria", but I don't know if that specific genus is described from this locality and the sclerites aren't star-shaped. It may be a related Chancelloriid, and it seems there are several described from China. My best guess is something like Allonia: https://www.researchgate.net/publication/316342674_Chancelloriid_Allonnia_erjiensis_sp_nov_from_the_Chengjiang_Lagerstatte_of_South_China http://www.paulselden.net/uploads/7/5/3/2/7532217/zhaoetal2018small.pdf I wish I could get higher-res photos of the sclerites but unfortunately I don't have a camera besides my phone. PS. Also, what could that grey+orange conical object next to the Chancelloriid be? Part of a trilobite genal spine?

This trilobite is identified as a larval Paradoxides mureroensis, specifically the late meraspid stage. It comes from Murero, Zaragoza, Spain, is 0.8 cm long and from the Middle Cambrian.

Protomelission is an early dasyclad alga and not a Cambrian bryozoan?
Oxytropidoceras posted a topic in Fossil News
520-million-year-old animal fossils might not be animals after all The specimens may be an ancient type of algae, not creatures known as bryozoans ScienceNews, March 10, 2023 The paywalled paper is: Yang, J., Lan, T., Zhang, X.G. and Smith, M.R., 2023.

Hello friends. It's been a while since my last post and I wanted to share with you my new acquisitions and, better yet, help me confirm the identification of these specimens. 1: The place of origin is Liaoning, China. 2: The place of origin is Yunnan, China. naraoia? 3: The place of origin is Yunnan, China. Isopyx minor?. 4: The last and my favorite (although a bit fragmented). The place of origin is Harbin, China. I appreciate the ID. They are not the best specimens, but I love these pieces.

What an adventure! I was on a trip to southern California with my partner. He does not like fossil hunting – yes I know what you are thinking but he is a very nice guy. You can’t have every thing! I wanted to go to the Marble Mountain Trilobite site in the Mohave desert. I did my research and knew exactly where I wanted to go. As I would be by myself I decided to be very clear about where I was going and how long I expected to be there. Off I went on a bright warm sunny day armed with gallons of water, a sunhat, fossil hunting backpack, many snacks, and a brand new Lexus. Yes I know you are thinking dumb dumb dumb! But as it turns out the lexus was an excellent choice, it had lots of power and reasonable clearance. I did high center it on some shrubs (sorry shrubs) and almost lost it in a sand bank. Power does win the day and I managed to get it about 3 miles away from the classic north end site by Chambliss. What I did not account for was that the recent atmospheric rivers had washed out a lot of the tracks and roads. I had a really big walk up to the base of the mountain. From there I struggled through boulders fields and scree slopes to get up to the famous red and green Latham shales. Oh boy what incredible rocks! Fortunately I am fond of lapidary too so I collected some glorious specimens. My aim was to find the blue green algal nodules formed by precipitation of the cyanobacteria. They look like elongated ovals and are found everywhere. I was gob smacked by these fossils. They are 518 million years old. The trilobites are mostly Olenellids and are rare. I struggled to find any of these and found mostly cool trace fossils. As I was completely exhausted getting to the top of this mountain and now had to get down it with a lot of rocks AND walk 3 miles across the desert to get back to the Lexus I made a decision – I would come back another day and find some of those trilobites. By the time I got back to the car my knees were shaking and I had drunk 5 litres of water and eaten everything I brought plus 3 candy bars. It was an amazing trip and the area is totally deserted. I never saw one person or vehicle while I was there. There is another trilobite site that is down towards the ghost town of Cadiz. This is the official BLM site and you are allowed to take small quantities of fossils. Unfortunately the road was completely washed out and unlikely to be repaired soon. Oh well that's for another day

Hi, i've just used my first binocular yesterday and decided to take a look on the pieces of schist i had collected in La Maurerie, member of the Coulouma formation, Cambrian, Montagne Noire, France. I need help to find out what i saw on them. Firstly, i splitted a piece of schist in two yesterday and found those tiny rounded things that puzzle me a lot. The whole of them form a shape of a little less than a centimeter. I also found that partial cephalon of one centimeter (part and counterpart) and wondered if it was from a Solenopleuridae or Trinucleidae. This really tiny pygidium of a few millimeters, i thought it could be from a Raphiophoridae or Dalmanitidae This one, a little bigger And that cheek and eye (the supposed eye is half a centimeter) @piranha @Kane

From the album: Nautiloid’s Trilobite Collection
This is a good sized example of this iconic Pioche Shale bug. It also sports a partial opistothorax, which is pretty sweet. Lower Cambrian Pioche Shale Nevada© Owen Yonkin 2023

I'm looking at an unknown trilobite from the Chengjang site in China and it has this weird looking thing on the thorax. Is it a fossil, and if so what is it?

Hello, Fellow Fossil Enthusiasts! I'm hoping that someone here might be able to help me in identifying these fossils, because I have hundreds of them in various stages of development, and in all of my research I have yet to find anything that remotely resembles what I've got! That is, until I found this forum - I've seen a few fossils identified here that were the very first that closely resembled what I've found, so my hope has been renewed that someone out there can help me out. I look forward to what new information might come my way! Scott
