This was in a box that was labeled trilobites from what was labeled Providence Mt in California. But to me does not look like a trilobite.

I visited the Quincy spot again, still with meagre finds but some were half-decent. I of course found some more disarticulated thoracic segments but they’re not worth posting, I found too many. Agraulid bits? The cranidium is probably a very badly preserved Skehanos quadrangularis. Some Paradoxides harlani bits, the cheek is weird because the genal spine is somewhat stubby. A very nice cranidium, and a nice size too, ~11 cm between the palpebral lobes, 7 cm from the anterior border to the occipital lobe. A pretty large section of thorax, with seven lobes. A little buddy. It was nice, but the rocks are very fragmented so there is almost no chance for a complete specimen.

I bought this fossil about a year ago and have had it sitting in my display cabinet front and center. It was sold to me as Vetulicola, it came from the Chiungchussu formation in Chengjiang, China. I was wondering if this is actually a Vetulicola species or a similar animal from the formation. It is right at 1cm in length, and the details seem pretty good up close. If it is Vetulicola, is it possible to assign a species to this specimen? Any help would be appreciated!

So, I will admit, I am severely uneducated when it comes to trilobites, but I’d love to learn more about them — the different species, what’s rare, what’s common, formations they’re found in, etc. I don’t have any in my collection yet, and I’d like to change that. Any recommendations where I could start my learning? Books, articles, papers, anything is appreciated.

I went hunting to the kinzer formation (cambrian) from a suggestion of a member here (thanks very much for that), and hunted for around two hours in the shale. Nothing I found screamed trilobite (my target fossil) but I did come back with a few interesting looking rocks. I'm not too familiar with the paleofauna here, so I'm putting most of my finds up here so you guys can tell me what fossils I've found (or lack there of).

Hi, I have this trilobite labelled as a Proetida. Also I was told it is 485-251 myo is this also right? Finally is it Moroccan if so I assume Atlas mountains? Thank you for your time!

A rangeomorph holdfast trace fossil from the Ediacara formation, Rawnsley quartzite of the Flinders Range, South Australia. This specimen is Medusina mawsoni, so called because it was until recently thought to be a jellyfish, but is now believed to be the attachment point of a fractal rangeomorph as Charniodiscus is the point of anchorage for Charnia sp. This one may have been the holdfast point for some species of Rangea. The diameter of the outer circle is 1.5 cm and the fossil is estimated to be 555 million years old.

Today I went back to the spoil piles at Quincy, with some better luck, and weather. I brought bug spray, which helped very much. I’m afraid this gives away too much about the site, but it was a very nice view. A picture of the site. The leaves were quite annoying. Some slickensides and a vug of pyrite which I did not keep, but were cool. On to the finds. I started out in the first few minutes with a lovely Paradoxides harlani left cheek. The rock is not tiny. Some fragments of pleurae. Some hypostomes, showing excellent “terrace lines”. A cephalic doublure, with half of a hypostome. Another more complete doublure. The cephalon might be there, but chances are slim. Some fragments of Skehanos quadrangularis. A cranidium and a heartbreaker thorax fragment. I wish that I had got there sooner, it would have been an awesome bug. A very badly preserved external mould of a Condylopyge eli. Still another species from this site, so I can’t complain. Now for the better finds of this trip. A really nice section of thorax, considering how fragmented this rock is. Four segments, it’s really the best one can expect from here. Not too shabby in terms of size, either. A really nice cephalon, if it were the positive. This one was really a shame, nicely sized too. And lastly, a decently preserved partial cranidium! Nice size, shell, definition, and… …there is a partial brachiopod on the side! I don’t think brachiopods have ever been recorded, or at least discussed from here. Something I never thought I would have found. Overall it was quite fun, I found some better material, and I will definitely return.

I've been sorting out my old collection and came across this, a slab of Lingulella davisii (M'Coy) from North Wales, near Porthmadog. It's from the Ffestiniog Formation, near the top of the Cambrian. I'm sure there's lots of it around but there don't seem to be many pics when I search, apart from in this paper: https://www.jstor.org/stable/pdf/1306865.pdf

From an old collection we got this strange Trilobite. I think it was found and imported to Germany around 1980 - 1985. Should come from Yunnan-Province in China (I only know it comes from china, did some research in the net and think it is a Yunnan-one). Lenght is around 18 cm (7"). Has short spines at the end of the pleural segments. The cephalon has been badly prepared, surface is a bit destroyed but the rim fits. Pygidum looks rounded, but under a microscope I could see, the end is not prepped and under the surface. Will do the work on it next time... What do you think about the genus? Before I start the prep-work I love to know if it has spiny ends, Looks not easy to prep... thanks for comments!

Found in spoil piles originating from the Hayward Quarry in Quincy, Massachusetts. Perhaps oxidised limonite burrow? Could the thing I circled be a poorly exposed Paradoxides cranidium? Burrow-like object is 2.2 in. or 5.6 cm. Braintree Argillite.

Today I decided to try my luck at Hoppin Hill. It was a bit too sunny, but otherwise good weather. The fossils mostly found are the small shelly fossils. I spent a good first hour and a half wasting my time on the extremely sparsely fossiliferous basal quartzite and grey argillite, on the west side of the inlet of the reservoir. I found a couple of ichnofossils, but not anything else. With little luck and half an hour left, I found the red slates on the east side of the exposure. The following are my meagre finds. Conotheca mammilata(?) Some extremely fragmentary trilobite bits. And lastly, a partial cranidium of Strenuella strenua. I will hopefully find some better stuff now that I know where the good outcrops are.

Hiya everyone I bought a small collection of trilobites last week. most are labelled, except these 3. They're Moroccan, and my guess would be Cambrian or Ordovician.
-
Hi, Can someone shed some insight into what this could be? They are from the Guanshan biota (Cambrian Wulongqing Formation, Yunnan, China). 5-6cm. My first thoughts were a Vetulicolian "head", but if the tail was lost I see no sign of previous attachment. It has a smooth, unbroken border all-around.

A Weekend Yorktown Trip to Surry County, Virginia (Feat. Some Cambrian Guests) 8/11/23-8/13/23
Echinoid Express posted a topic in Fossil Hunting Trips
Hello everyone! I had the opportunity over the last weekend to visit a spot in a campsite along the James River that had an outcropping of Pliocene Yorktown Formation fossils, as well as some "visitors" from the Cambrian Swift Run Formation of the Blue Ridge Mountains of Virginia. This was my first hunting trip that was outside of North Carolina, which was really exciting for me! While it was miserably hot and humid, and I had a stomach affliction for the duration of the trip, I made the best of it and found some really cool fossils, and met a lot of interesting folks. In all, over 70 people from various organizations were there. I have quite a few pictures to share, so hang in there with me! These are a few photos of the area on the river. The area we were in was brackish, and the camp beach there was recently worked on, which limited some of the fossils in the immediate entrance area. However, further down either side there were a lot more fossil piles. It was neat being able to look up and see all of the shells exposed on the cliffside. These huge chunks of material containing tons of Chesapecten scallops and other fossils were found in several areas. They were more plentiful before the beach replenishment from my understanding Fortunately there was not anything dangerous encountered over the weekend, but plenty of little critters were out and about. (Especially ants!) The hunt went from Friday evening to Sunday morning. On my way out on Sunday, I was given a lift back to my vehicle by a kind family from the Richmond Gem and Mineral Society, who were also nice enough to lead me to a well-known tulip poplar tree on the site. This massive tree is over 400 years old, and it takes about 8 fully grown adults hand-in-hand to fully encircle the base of the trunk. Now, on to the goodies I picked up. The majority of the fossils I picked up were varying sizes and species of Chesapecten scallops. I looked really hard for an intact echinoid or an Ecphora murex, but unfortunately I didn't get that lucky! As for the Chesapecten species names, and that of several other fossils as well, I am still in the process of learning them, so my detailed information will be lacking. I'll stick with my best finds, but this is a little group of mostly Chesapectens I had laid out while organizing my finds. Here are a few Chesapecten I had that had some variable colors, including my largest three specimens. They measure just over 15.25 cm (6 inches) wide. They have been brushed with water to show the color better. These are some random fossils I found including two coral fragments, several gastropods, some partial tube clams and some loose bivalves. This is the largest venus clam I found in the hunt, around 7.6 cm (3 inches) wide. These typically held together better than a lot of other aragonite-based shells. I found a few intact bivalves in a section of the cliff that had slid down to ground level, but most of them were so fragile due to their aging aragonite that they broke apart upon handling; some even had the physical consistency of the sand surrounding them! These are some ones I found that stayed intact to some degree, and one that had mostly broken away. While they're not the prettiest specimens, I realized they could be used as a cool visual example of how steinkerns form. I'll have to find a way to stablize them a little better so I can get them in a display box. While most of the bivalves were very brittle, some had undergone a mineral change and had their aragonite replaced with calcite. They give off a faint greenish-yellow glow in UV light, which made for a fun late night activity! One man even found a cluster of calcite crystals from the formation! Here are two intact calcite clams, and two loose calcite shells I found. This was a rather sizable Crucibulum limpet I found, also referred to as a "cup-and-saucer snail". It's a little over 3.3 cm (1.3 inches) at it's widest. This was the widest barnacle I found during the hunt, and it's over 5 cm (2 inches) wide. Here are a few barnacle clusters I found that had some nice pinkish coloration preserved on them. Here are a few intact oysters I found. The smaller one had quite the barnacle attached to it! Someone at the hunt suggested that this particular bone fragment was possibly avian. There were a lot of whale bone fragments around the site, and there have been some pretty sizable speciments found there, including whale vertebrae and whole dugong ribs. This ray tooth fragment was the only fish fossil I found myself during the whole hunt. One young woman found a 2 inch mako tooth, while another woman found a fairly sizable megalodon tooth. Jumping back to my Chesapecten, This is a medium specimen that had some very large barnacles on it (perhaps Balanus concavus?) They're probably the longest ones I found, measuring around 5 cm (2 inches). Here is a cluster of some very small Chesapecten. This is a fairly colorful specimen with some equally colorful barnacles attached to the exterior surface. Here is one of my largest specimens of Chesapecten (15.25 cm / 6 inches) next to my smallest specimen (1.525 cm / 0.060 inches). These are some pathological Chesapecten I found, although I'm not 100% sure about the third one, it might just be damage. Now on to my top favorites, this is a cluster of small to medium Chesapecten I found. There are some tusk shells on the interior side, and there is a Discinisca lugubris brachiopod on the right side exterior. This large Chesapecten has a calcite-replaced clam valve right on the rim of the shell. I had found this one on Friday and I didn't learn about the presence of the calcite replaced shells until Saturday, so it went unnoticed until I was washing it at home. I was too busy admiring the huge scallops everywhere! While I didn't find any intact echinoids there, I did find this oyster shell that has a small fragment of what appears to be from a regular echinoid on it, but I'm still not 100% sure. I also found this Chesapecten that appears to have a sand dollar fragment attached to it. Given the age and formation this might be a Mellita aclinensis fragment. A whale tooth fragment I found on Friday. A boy found a whole one there just before I arrived, and it was over 5 cm (2 inches) long. Now, we're down to my absolute favorite finds of the weekend. Here is a whole Chesapecten jeffersonius with both valves in fairly pristine condition. There is only a very minimal amount of hard buildup on the valves. I also found this specimen, but unfortunately it had a hole through one valve. Still really cool though! These are cobbles that contain Skolithos trace fossils from the Swift Run Formation, which is an Early Cambrian rock formation in the Blue Ridge Mountains of Virginia. They would break off during the upheaval of the mountains and eventually get carried in water currents all the way to where they were found in the current age. These are the oldest fossils I've found myself to date. And last but not least, here is a fairly pristine Chesapecten jeffersonius(?) valve I found with some good color. However, the most interesting part of this one is that there appears to be something in the resilifer of the shell, almost like shiny red nacre. This is the only one I picked up over the weekend with this feature. I wondered if it could be a preserved ligament, but I was a little unsure; I figured this would be the best place to possibly get some insight on it for the moment. The exterior was brushed with water to show color better. That's all for now! I've got a family trip to the southern NC coast planned soon, so I might try to swing by Holden Beach and nab another batch of Cretaceous fossils while it's still producing a lot. I'm also hoping I can find some local Triassic material before the holidays, I've got a few promising leads on some spots, including one right down the road. -Tony- 2 replies

Hello! I am a newbie fossil hunter, and I am asking for some ID help. My son and I visited the Kinzers Formation near Lancaster, PA , to look for fossils in the Cambrian shale. We didn't find much, which seems consistent with peoples' experiences recently, but did find traces of something that we haven't been able to positively identify. The attached photos of the specimen come from a piece of shale the we split. There's a radial pattern of darker flecks on the left side of the rock, each about 1 cm long. The tape measure is next to a longer, darker shape about 1 cm wide and about 6.5 cm long (although broken off on the right). Hopefully these pictures are helpful, but I can get out my SLR if more detailed pix would be helpful. Thanks for your thoughts!! Kerry
