Can anyone help identify this soft body? I found it in the Utah - Wheeler Shale formation while searching for Trilobites. I am always keeping my eyes peeled for any soft bodies such as worms, algae, etc. and came upon this after splitting a rock. It is roughly 16 mm long with a body that can be best described as an olive with 2 stalks sticking out the top end. There does not appear to be any missing parts, although this may be a partial body. Evidence of this is the organic/mineral "halo" which can be seen around the body. Also, there appears to be an alimentary canal progressing through the middle. Any comments or ideas are welcome.

A few weeks ago I was on my very first fossil hunts. With some beginners luck I managed to find a few trilobites and orthoceras but I also found a very peculiar fossil that I am very curious to learn more about. The place where I found it is called the Aland Islands and is located in the Baltic sea between Sweden and Finland. Ive read that the fossils in this area comes from either the Ordovician or Cambrian ages but I am clueless on which age the stone comes from that containes this fossil. It appears to be complete only missing one "eye" on the half that is exposed. On the negative I can clearly see the "eye" imprinted. The shell/skin is extremely fragile and crumbles if touched and most of the shell/skin is stuck in the negative. When I turn it upside down I can see that the fossil is symetrical with half still in stone and other half exposed. It is approx 7 cm long, 4 cm wide and 2,5 cm high. Anybody got any ideas what this might be? Ive searched thousands of pictures in this forum and on the internet but nothing even comes close.

Hi All! Some of you know me already, and I've been occasionally browsing the forum for years. I saw a couple of recent-ish threads that I wanted to comment on, so thought I should sign up at last... For those who don't know me, I'm a semi-independent researcher with honorary positions in Nanjing and Cardiff, while living for most of the year in the middle of nowhere (the wonderful little town of Llandrindod, central Wales). My main interests are the early evolution of sponges, worms, and early Palaeozoic ecology, but I basically like really old dead stuff, and the weirder the better. I've worked on a wide range of Lagerstatten, including the Hetang, Burgess Shale, Sirius Passet, Afon Gam, Fezouata, Llanfallteg, Llandegley Rocks, Llanfawr, and Anji biotas, so I tend to get around a bit when time and energy permit. I'm an old-fashioned palaeontologist, though, and am adamantly against the view that we now know the fossil record well enough to start concentrating on number-crunching. Everything I see on fieldwork suggests that, at least in the Ordovician, we don't yet understand even the basic diversity. That might possibly be correlated to studying a group that preserves largely as enigmatic blobs that everyone else ignores, but hey - it's a niche! The moral is, though, that amateur palaeontologists are increasingly vital in keeping the new finds pouring in. There's a vast amount out there left to discover. I'm not necessarily going to be able to keep up with everything on here, so please feel free to nudge me towards particular threads if you'd like my input! Looking forward to getting stuck in!

A new trilobite for my collection I don't think more complete specimens exist.

Hello, all. After my last wonderfully successful Id effort on here, i thought I'd try again. This specimen was boshed free of some matrix that was sent to me by the unrivalled Ralph @Nimravisin a batch of matrix from the Conasauga Formation, Upper Cambrian, Georgia, USA and home to a multitude of the trilobite Aphelaspis brachyphasis as well as rarer agnostids and other even rarer trilos. I was looking at this paper https://www.researchgate.net/publication/250083071_Exceptional_fossil_preservation_in_the_Conasauga_Formation_Cambrian_Northwestern_Georgia_USA and thought my specimen below looks rather like the example D in Figure 3 (sorry, I don't know how to just post that image. It's a chlorophyte, so is mine ? They appear to be sort of tiny strings of sausages, the longest string being about 2 mm long, so each individual 'cell' is very tiny indeed. Thank you for any comments, ideas or suggestions. Adam.

Hi, i've bought that trilobite last week-end in an exposition of fossils and minerals. I've forgotten to ask what trilo it was and the seller forgot to tell me. I know it's a Redlichiida, Ellipsocephalidae, Hamatolenus from the Cambrian of Morocco. If one of you had an idea about its genus, it will be welcome. P.S. appparently, it was in the ptychopariida order and would now be in the redlichiida order, or am i wrong ?

Hi! I was searching my backyard for fossils (even though I knew I probably wouldn't find anything), when I came across a piece of shale that was splitting. I used my pick to split it, and I found these "fossils". I'm not sure if this is even a fossil, but it looks like some kind of carbon film. They were so small that I couldn't take any good pictures of them. Each of these "fossils" are ~2 cm long. The rocks I found these in were there when I moved into the house, so I don't know if they were already there, or if they were imported. The first one resembles the possible anomalocaridid relative Pambdelurion, or at least that's what it resembles the most. The second "fossil" is what looks to be some kind of Arthropod with overlapping swimming fins. The last one looks to be some kind of frond (possibly algae?). Any help would be much appreciated, even though I doubt they are even fossils.

Well I finally had the opportunity to head out to Millard Co. with my Geology professor, the esteemed Forest Gahn. He is one of the worlds leading experts in Echinoderms and he specializes in Crinoids. The guy goes diving a lot to study Echinoderms in their natural habitat and he's managed to keep some Crinoids thriving in a tank at BYU in Rexburg, Idaho. Here's some pictures of the trip to some special Geology and Paleontology sights in south western Utah. I had a blast. Students sitting on the edge of Fossil Mountain, one of the richest Ordovician deposits in the world learning about it's geology from Forest Gahn. The major fossiliferous formations are the Juab and Kanosh Shale formations. In a remnant of the last ice age lake, Lake Bonneville forest scopes up a handful of algae and cyanobacteria rich mud along with Playa (dried up lake). This is an extinct marine animal known as a Graptolite discovered at a nearby Ordovician road cut in Millard Co. UT. No trip is complete without trilobites. Here's a large Asaphiscus wheeleri molt from U-Dig near Delta, UT. This Native American arrowhead was recovered in Millard CO Utah during one of our hikes. My professor claims its origins may be from the Shoshone Tribe. Forest teaches students about the Cambrian marine fauna at U-Dig near Delta, UT. Forest shows students the fossilized remains of a Stromatolite (just above his knee) colony alongside the Lake Bonneville Playa (dried lake) near Notch Peak UT. Here is the view of Fossil Mountain in Millard CO, UT at sunrise. At dusk on the first night we camped at the dunes of Little Sahara which are composed of ancient sand deposits from the Sevier River dumping into Lake Bonneville. Perhaps one of my favorite parts of the trip was being let into the collections archive room at the BYU museum of paleontology in Provo, UT. A lot of the dinosaurs in the collections here are from the Saints and Sinners Quarry in Colorado. Lots of neat therapods including a near complete Allosaurus.
