Mouth of Anomalocaris
crimsonfossils posted a topic in Partners in Paleontology - Member Contributions to Science
Contributed this anomalocaris mouth to my university’s collection for research. Owner of the quarry said he only finds one every decade or so. Found in the Wheeler Formation in Utah (a Konzentrat-Lagerstätte where soft bodied organism can be preserved).

First Post! - Californian Anomalocaris
Sarcopterygiianson posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hello! This is my first post. I'm happy to meet you all! I currently have a very modest fossil collection, but have been keeping my eyes peeled for some specimens that I was really excited about. I came across this fossil, which I was considering adding to my collection. It is described as a 200g fossil of a 60mm Anomalocaris appendage next to a small brachiopod. It was found in the Latham Shale in the Marble Mountains of California, and it's indicated that finding these is a very uncommon occurrence. I was wondering if anyone here might have insight as to if it's real, fake, or restored in any way. Thanks!

Greetings. On 8/6/23 I was out around Pioche, Nevada looking for trilobites. I found a number of specimens and decided on a whim to bring some larger sections of trilobite-bearing shale home for context purposes. After sorting the smaller trilobite samples I sat down to inspect the larger shale pieces. There was one item that I could not identify and I wonder if it might be part of an anomalocaris grasping appendage. Below are two pictures, one is a close-up and one that is a larger shot containing a trilobite cephalon for comparative purposes. The spine at the end of the (maybe anomalocaris) lobe is not as long as most I’ve seen in pictures but I did find one from China that resembled the one in the picture rather closely. Would any of you kindly venture an opinion as to what I may have found? Thanks in advance.

Hello friends, I confess I was looking forward to the return of my favorite forum. I would like you to help me identify the following fossils, the first is from a theropod from the Kem Kem area and measures 2.5 cm. The other specimen comes from Yunnan (China), it measures 3 cm and they told me that it would be a "tooth" of anomalocaris. As always, I am extremely grateful for your responses! Theropod:

Is evidence of predation on trilobites common?
joaoarguello3 posted a topic in General Fossil Discussion
I have a question that came up a few days ago. I was taking a look at some common trilobites on online sales sites (some of the most common trilobites for sale in the genus Elrathia) and came across some specimens that were allegedly attacked by anomalocaris. I have various doubts. How common are trilobite fossils that suffered from predator attacks? Is it possible to know which animal was the one that carried out the attack on the trilobite? Could they be poorly preserved or molted specimens of trilobites? I leave some images of the alleged trilobites that suffered the attacks.thumb.jpg.3538d35b702ceb0718cdd61e9ff715b8.jpg)

Hello, I just got this supposed Anomalocaris fossil from Yunnan of China, Cambrian in age. It's about 1.5cm length, and I belive a section from the end of an appendage. I was wondering if someone could determine a more specific species ID for it? Hopefully my phone's camera is enough to show the details. The specimen has quite clear preservation of the ventral spines, as well as their auxiliary spines coming off the front and back, and based on that I am thinking something like Anomalocaris kunmingensis (https://www.researchgate.net/figure/Anomalocaris-kunmingensis-sp-nov-from-the-Guanshan-biota-Yunnan-China-a_fig2_257689210/amp). But of course I don't know what I don't know. Thanks.

Hi, I have this mystery piece of what appears to be anomalocarid appendage of sorts. The problem is I did not receive any information with it and it came out of an old collection from Maine, Usa. I'm not to sure what else it could be from the appearance but I am also very uncertain of the exact species. The piece of a very laminated sparkly shale If I had to guess it could've came from either Burgess Shale, Utah, or Nevada but I not sure what locality it could be from so if anyone if familiar with these shales and can tell from the preservation it would be a huge help, thank you and looking forward to seeing peoples opinions, and if anyone can recommend an expert to show that would also help.

I am sorry for the length of this txt. I am looking for help verifying the ID of a fossil I've been finding for close to 20 years now. It is a very dificult to see poorly fossilized shrimp or trilobite like creature that everyone I've spoken to tells me can not exist. I am having a dificult time getting pictures that people on other sites will take seriously as the lines defining the structure of the creature are nearly undistinguishable from the stone itself. Everyone wants to call it pareidolia and say there is nothing there. Four or five individuals I've spoken to, whom have taken the time to actually look at it have seen it after I've pointed it out several times and sketched over a picture. They eventually get the typically *holy snarge I can see it look and then go on to profess they have no idea what it could be. So it seems that some people are capable of seeing the same things I do. But honestly I'm tired of people proclaiming to have degrees treating me like I'm some spoiled child when they can't see it so I am flat out refusing to posting pictures and an explination of it unless I one; can get an explination as to why it's a natural formation and why rocks with natural formations have markings that exactly resemble the cells of chitin found on modern crayfish and lobster, or I get someone with true knowledge who can explain something about what I'm looking at. I started recognizing this in local stone almost 20 years ago. No one I have showed it to in all that time has so much as come up with a guess as to what it might be. Most can't see it at all, though it takes no special ability to do so. It just requires a maticulous attention to detail. And a willingness to believe that there are things in the world that have not been discovered yet. This is a thing that has been discovered, and is actually fairly well known. But noone believes it can fossilize in this format. And their is no mention of it ever being found in this location before. I'm not willing to argue with anyone about it's validity as a fossil. It is organic and it is a fossil unless you can explain as I've mentioned above. I will not accept any other answer period! That may make me sound uncooperative and hostile I apologize if that's what you see or think. I'll do everything in my power to explain what I'm seeing and get you to see it as well. But I'm done making enemies by refusing to accept that this is not a fossil. Either work with me and help me prove it. Or don't. But if you act like the teenagers on other sites I've made the mistake of looking for answers on I don't need your input. That said I've seen nothing but courtesy and respect from the people here so far so I'm going to try this one last time. Please respond if you are interested and I will post pictures and explinations as I have them as a new topic under this one

When faced with a radiodont appendage fossil; How does one effectively determine which slab contains the "part" or "counterpart" ? For reference, here's the holotype Pseudoangustidontus appendage. The first pic, Figure A, is apparently the positive(?) "part" of the fossil. Whilst the second pic, Figure C, is apparently the negative(?) "counterpart". Like it's easy to tell the difference between an impression/cast, or the actual fossilised remains for hard-bodied specimens like shells, exoskeletons and bone. But for some soft-bodied organisms, it's especially difficult when both slabs seem to preserve both the impressions and the fossilised remains of the organism, as in the case with the Pseudoangustidontus holotype. I've also heard that concavity of the matrix usually helps in identification; but thin and soft-bodied specimens often just leaves a planar imprint, so judging by relief might not be too reliable either. Any thoughts on this matter?

Got to work on these guys because some of these creatures were my inspiration of what they would have looked like in color and others are at an art show. Wonder what animals will you like to see when its unleashed before your very eyes?

Different lighting to highlight fossil differently -

Both of a single anomalocaris' appendages. Possible anomalocaris goo? A speculation I think would be very cool, that the splotchy splatters around appendages could, however likely or unlikely, be anomalocaris "filling" or fragments, since it appears the whole animal was present at the beginning, and maybe included in fossilization, immediately below the edge of this piece, since the 2 appendages are in articulated position. -

Another smaller anomalocaris appendage. Possibly different species than the 1st. *more info coming -

Does anyone have any fossils of, or with anomalocaris BODIES? I'm interested in seeing what they look like. I did searches for them and they all look so random, without any features except for the overlapping ends. Even the beautiful full-animal fossils have bodies like that. Did they always fossilize so unimpressively?

Is this an anomalocaris appendage? It was labeled as resembling an anomalocaris appendage, but Ive never seen one that looked like this, and I feel like Ive seen something else similar to this before. *wheeler shale, Utah.

Ive seen a couple "fossils" recently, that have a feature that makes me wonder if they're authentic. Especially because the fossil on one looks more like it's been just stained on the rock surface, than having any actual impression. My question on here though, is if fossils can continue over creases on a rock, that appear to be a break in the level/time (the crooked line going along the underside of the apparent appendage). It's not an actual clear separate level, so I know a fossil could lay across an inconsistency on the original surface, but this one looks more like a break, so I'm wondering if this angle is possible.

Anyone here have any Anomalocarididae fossils? I do realize that if anyone did they most likely wouldn't be on this site but just wanted to know. I also realize that they are extremely rare but that I've seen things on here comparable when speaking about rarity. (Kinzers Formation PA has confirmed - anomalocaris pennsylvanica.) Thanks;

This cool pic of an Anomalocaris canadensis arrived today in the mail! Done by a great Japanese paleo artist whos main love is Cambrian critters. I sent him a Chengjiang worm and Isoxys fossil as trade. I love this pic! In September I'm heading to Bali to visit my brother who runs a yoga school there. I'm going to get an Anomalocaris tattoed on my forearm and I'm thinking of using this image. Its very dynamic!

Hi my name is William, As I don't have much to show yet. I will soon. I have this cool Ammonite fossil that I plan on 3D modeling and animating and will post on the forums when finished. I am also working on an Anomalocaris, and a Hallucigenia. Cambrian animals. Hoping to have Anomalocaris concept finished this weekend. Stay tuned. Thanks, William This is the 3D Scan of my Ammonite fossil. Actual fossil and size comparison. Hallucigenia concept. The back end of this guy I felt to me was an air sac to help it attach itself to rocks like a suction cup. If that is the back end? My spread of how I want my Anomalocaris to look like. As far as what I can see according to its fossil record the eye sockets extrude out on its sides. I gave its fins an even symmetry on both sides in a diamond shape as a whole. The fossil looks like it shows otherwise and I have seen some with symmetry. I think as it was fossilized I believe it was turning to cause a foreshortening on the imprint of the fossil I see. Not sure... that's why i'm on here.

From the album: Anomalocaris and friends.
A large grasping appendage of the Chinese Anomalocaridid, Amplectobelua symbrachiata. A cousin of the Anomalocaris. This grasper is a very large example at 89mm. From the Maotianshan Shales in Chengjiang. Lower Cambrian, ~525Ma.- 2 comments
