Hi, I'm a newbie to this forum and would really appreciate some help identifying a fossil that my son found last week in mid-wales, Upper Gilwern Hill Quarry, Powys. It was found in the same strata of slate with trilobites that the quarry is famous for. multiple photos attached. Many thanks in advance for anyone who can help identify it.

Looking for help with this Early Ordovician (Floian) trilobite from the Powell Dolostone of Arkansas, USA. The specimens (GRAY FIGURE below) were identified by Taylor (1968) as cf. Lannacus nericiensis Wiman, but that species (now a species of Megalaspides) doesn't seem like a great match, as the author notes in the paper. In fact, I'm not sure that proper Megalaspides even lived in North America. Last week, an Arkansan found another asaphide specimen (MAIZE AND BLUE FIGURE below) in these same rocks, which may or may not be the same species as the specimens described by Taylor. -
Ok, i know that barnacles are arthropods. But, i can understand the anatomy. It is a shell that the animal make for "home" and the animal is free from this, or the shell is part of the body? Can an adult barnacle moved?

I was given this Eurypterid fossil a while back and I was looking to see if anyone had any ideas towards a species, i’ve got no idea where it came from other than somewhere in the New England/Canada area. Someone has told me it looks like an Adelophthalamus but id like some more opinions. Thank you

Hi, it's time for the next 3d-printed animal from the Cambrian: Kylinxia zhangi. It was described only about a month ago (https://www.nature.com/articles/s41586-020-2883-7) and features Anomalocaris-like frontal appendages and Opabinia-like eyes on an early arthropod body. The model in 1:1 scale is only about 6cm long. The legs, while considerable thickened to allow printing, are still only about 1/3rd of a millimetre in diameter. It was printed on an Anycubic Photon Mono X at a resolution of 50µm from transparent resin and painted using an airbrush with highly thinned paint, such

Hey everyone, I just got back from an amazing trip to Utah and Nevada collecting a host of trilobites. I am going to try and post some photos of that trip in the next day or so. I never seem to be able to find the time anymore! This find was pretty much the trip maker for non trilobite finds. I found this soft tissue arthropod in the house range in rocks known to have Burgess Shale fauna. So far this doesn’t seem to line up with anything I’ve seen in the Burgess. I’ve had 2 suggestions on an identification. Canadaspis perfecta is the best guess so far however there are g

Hi Forum members, Yesterday I went to a spot in Herkimer County in search of Eurypterids! This spot exposed the Fiddlers Green Formation of the Upper Silurian Bertie Group. I had never found a Eurypterid so I was excited to go, and I had heard this was a productive spot. I got there and the first rock I looked at had an exploded eurypterid on it! There were eurypterid bits and pieces all over the place. Eurypterids seemed to be much more abundant at this spot than I thought they would be! I only got to stay there for a half an hour but managed to trac

Hi, Just wanted to ask if this listing is correct in regards to the identification. It is listed as the fossil head of the Anomalocaridid genus Aegirocassis. It is said to be from the Lower Fezouata Formation in Morocco dated about 480mya - so i believe the locality is correct for the species. Thanks in advance!

I received this fossil from a family friend to help with an assignment I am required to do, however, to complete it I need the taxonomy of the specimen. if anyone can help me with the species name for this fossil that will be greatly appreciated. (it was found in the Yass, NSW area for reference)

Unknown large trilobite- fake, or just badly prepped?
Parthicus posted a topic in Is It Real? How to Recognize Fossil Fabrications
I am hoping someone can help me with this large unknown trilobite. It was given to me many years ago (late 1980s) by my father, along with some other trilobites and other fossils, as a Christmas gift. He acquired the fossils from a member of the local fossil club (Delaware Valley Paleontological Society) and most were carefully labeled, but this one was missing its label. It is a large, partially enrolled trilobite (15 cm from "nose" to tail if unrolled and 6.5 cm at the widest point); there are small bumps down the middle of the thorax and on the glabellum. It is on a chunk of matrix that -

Since last year, I was starting hunting down all types of Bristolia genus. I am so fascinating about its shape. Here represents all the species I have acquired: Bristolia bristolensis (Resser 1928) Types: USNM 78390, the lectotype (defined in Palmer and Repina 1993); paralectotypes USNM 78391 and 78392. Bristolia bristolensis had originally been recognized (e.g., Riccio 1952; Palmer and Halley 1979; Palmer and Repina 1993) as a highly variable species, particularly in the condition of the intergenal and genal spine angles. However, Lieberman (1998) used uni
