Culpeper Basin Unknown
patelinho7 posted a topic in Fossil IDHello all, Quick backstory on this: I’ve been researching the Triassic Culpeper Basin of VA for a little while now. I’ve been paying more attention to various formations I see when I’m around northern VA especially after reading more about the stratigraphy of the area from old papers. I’ve taken a special interest in this red mudstone (or is it siltstone or sandstone? I don’t know the exact difference to be honest) because it’s what I’m familiar with. I participated in this program as a kid with Dr. Peter Kranz where he took us all over the DC area during a week in the summer and o
Is this a ghost shrimp/crab burrow?
Mosasaurhunter posted a topic in Fossil IDHello, I recently found this in a Ripley formation exposure near my house. I think it is a crab or ghost shrimp burrow of some kind but I’m not sure exactly if it is or not. Any help would be appreciated, thanks.
Possible Trace Fossil
Andúril Flame of the West posted a topic in Fossil IDHello all, A few months back I happened upon an intriguing rock while taking a walk in the woods. The main groove on the front of the rock struck me as a possible trace fossil (perhaps a worm burrow or a tunnel created by plant roots). I considered the possibility that it could potentially be a fossil since it was found in the Newark Supergroup of northern Virginia which is know to have some fossiliferous rocks. However, I fully expect that it is simply an artifact of weathering or that it has a geologic origin. Can any confirm whether it is a trace fossil or simply a case of weat
Mazon fossils donated to the Indiana State Museum

Trace fossils on Upper Jurassic sandstone
Aerson posted a topic in Fossil IDHello people of ichnology. I'm studying a Rift basin in Brazil Northeast, related to African-American break-up of Gondwana. This unit is mostly composed of braided river deposits (coarse sandstone and conglomerate) interbedded with paleosols. Due to high deforestation of the region, this area is in being eroded and losing considerable mass, and oftenly new outcrops are formed. Considering this, I bring to you a concern for the identification of some trace fossils that appeared, in order to manage strategies to prevend it's destruction. In the left corner
Serpulid or Vermetidae?
Lone Hunter posted a topic in Fossil IDI already had 2 little piles of worm tubes then I found this larger single one today and appears the tube broke and exposed the worm. Examined the smaller ones more closely and noticed they have pyritized insides and cracks like on shell, started to wonder if they were gastropods, I see shiny spots and know the worm isn't preserved and tubes aren't shiny so doubting if they are Serpulid tubes. Also see what appears to be apeture on larger worm, so what are they? Last picture is backside of large one.
Gastropods or tube worms?
SilurianSalamander posted a topic in Fossil IDFound these weird spirals in this chunk of agatized rock. Devonian from Bradford beach in Milwaukee. Thanks!
Mazon Creek ichnofossil?
Sauropod19 posted a topic in Fossil IDHello. I found this piece during my first visit to Mazon last year and just got around to asking about it. I believe it may be tracks of some sort, as they look vaguely like other arthropod ichnofossils. I was wondering if anyone may be able to confirm my suspicions and possibly ID what kind of animal it could be. I understand this second part is difficult without anything else to go off of, and I apologize for lower camera quality than the other images I’ve seen here. Thank you!
Paleozoic trace fossils?
SilurianSalamander posted a topic in Fossil IDSorry for lack of scale! Cambrian-Devonian rocks here. Found in the side of a building.
Trace fossil conostichus?
Sandfossil posted a topic in Fossil IDMuskogee, Ok USA. Could these be conostichus or something else? I have found many in sandstone but never in shale. These were found about 20' below where I normally find the sandstone conostichus. I am including a picture of some sandstone conostichus for comparison. Would the shale ones be older since they were found in the hard blue shale 20' deeper? Thanks for your help.
Devonian worm burrows or organ pipe coral?
SilurianSalamander posted a topic in Fossil IDFound two of these fossils now. Both on beaches that are probably Devonian in age. One is from SW Wisconsin on Lake Michigan and the other is in the Lower peninsula of Michigan from the shores of Lake Huron. Organ pipe coral or some sort of burrow trace fossil? Thanks!
Curiosity is killing this cat!
Aussieopal posted a topic in General Fossil DiscussionHi everyone, For a week straight I have been searching what the heck a guys trace fossil on Facebook may be... He says he found it in Bradford on Avon west Wiltshire South West England. When I google search his images I keep getting trilobites, bivalves and brachiopods come up but it really doesn't look like any of these that I have seen anywhere. In over a week he hasn't received any suggestions other then hydnoceras but again it is nothing like any I can find and doesn't seem to be of the right time period. It's really starting to annoy the Aqua
Spine like trace fossil
Lone Hunter posted a topic in Fossil IDCollected this in Woodbine formation, I've searched through trace fossils but haven't found a match assuming that's what it is, hope it's recognizable.
Any Trace fossils that can be ID’d? North Alabama
Steph posted a topic in Fossil IDHeaded back to area where these were collected this weekend (Crane Hill, AL) & would like to know if I should keep collecting similar rocks? If fossils present, how can they be better delineated? 3 Specimens: 31-trackway? 30- 29- Not sure the best angle for this one so multiple pics. Last 2 pics are the back.
What makes these beautiful patterns?
Steph posted a topic in Fossil IDI’m probably getting close to my question limit for today, yet I can’t stop thinking about the pattern on the rocks. Are they trace fossils or just pretty iron staining? I’m headed back to where I collected these (Crane Hill, AL) tomorrow & it would be nice to be able to explain to my nieces. I was thinking about Graptolites, though I can’t match up the patterns to those I see in my books. Google search of pic 1/2 pulls up Stromatolites. Pic 3 is the back of pic 1/2 pic 4 includes more examples Thanks for looking.
virginia triassic. trace fossil?
val horn posted a topic in Fossil IDwent hunting in virginia triassic looking through red stones in construction zones. Didnt find much, the one thing I found looks like a trace fossil to me, though I dont recognize it. I am open to suggestions, the trace is 8c m by one cm of a looking like series of circular flat disks on a thread.
Upper Ordovician ichnofossil - bifungites (?)
Rogue Embryo posted a gallery image in Members Gallery
From the album: Camille's fossils - Georgian Bay FormationThis dumbbell-shaped ichnofossil measures about 7.5 cm long, including the terminations -- considerably longer than the Ordovician and Devonian bifungites specimens described in Pickerill and Forbes, "Bifungites of Halli from the Ordovician (Caradocian) Trenton Limestone of the Quebec City Area" (1977). Field collection by Camille Martin, May 28, 2018

Mazon creek ID.
TheRocksWillShoutHisGlory posted a topic in Fossil IDI came back across this fossil after taking another look through my Mazon creek collection. It looks like some type of creature with a preserved trail? I had previously missed it, thinking it was part of plant material that it is associated with.
Marine Trace Fossil?
Ramona posted a topic in Fossil IDMy son found this in Lost Creek in Russellville, Alabama. I am assuming it is a marine trace fossil but someone locally had another idea that is so far fetched I won't even mention it here, LOL. I figured I would check with the experts to see if they agreed with the simple explanation first. Thanks! Ramona
Burrow cast in Chinle Formation
kgbudge posted a topic in Fossil IDTrace fossils aren't always as exciting, but I like the ones I've found. This looks like a burrow cast. From the "mottled member" of the Chinle Formation, Temple Mountain, San Rafael Swell, Utah, US. Posting also to check my identification. My references indicate that the mottled member at this locale is known to have lungfish burrows ... unless they're crustacean burrows. This one seems large for a crawdad (even a Triassic crawdad) but small for a lungfish.
Graptolites, or something else?
kgbudge posted a topic in Fossil IDA fossil buddy sent me these photos. His thought was trace fossils, but looking more closely, it seems to me these might be graptolites. I confess I've mostly hunted in beds well past the geological peak of graptolites and are not as familiar as I might like.
acetabular posted a topic in Fossil IDI just found this piece in a parking lot in Ann Arbor, Michigan. The stone was taken from some quarry and dumped here, so there is no geographic or temporal control, but I was wondering if it was a trilobite (since that's what it looks like to me). Thanks!
What is this trace fossil?
sharkysaurus posted a topic in Fossil IDHi everyone! I recently found a trace fossil near my house. I live in Southeast Colorado Springs and there's a lot of marine fossils near where I live. I found what I believe is an ammonite trace fossil. I'm having some trouble identifying it though. I'm not exactly sure what ammonite it's from as well as what formation it's from and what type of stone it's in. I brought it in to the museum I volunteer at and it was determined by the curator that it is not sandstone and it's most likely from the Late Cretaceous. I think it might be from a Hoploscaphites cheyennensis in silt-stone from maybe th

Trace fossil ID
Lone Hunter posted a topic in Fossil IDEagle Ford sandstone, found a cool trace fossil and curious what made it. Could only find one somewhat distinguishable thing and really can't tell what it is other than looks like shell. Lots of burrows and maybe worm? Found several little circles with dot in the middle but hard to get all images. The trace looks like a sperm best way to describe it.
