Awhile back @Rockwood posted something similar to this and was given the ID Serpulid Reef, which I had never heard of until then. Would that be what this is? This is from creek in Eagle Ford, what's most curious is how the wad of spaghetti perfectly comes together at the mouth(?)end. Pictures I've seen of these reefs show worms poking out out in every direction.@erose

Hey all! Throughout my many years collecting from around the Cotswolds, there has always been one constant: these weird, tubular structures. Originally, I thought them to be corals, when I was much younger. More recently, I have IDd them as the ichnofossils of a Serpulidae. If anyone could confirm or disregard this ID, I would be very thankful!

Hello, I noticed this looks like worm fossils, is it? I went to take some more pictures, but I think I've taken it away, so sorry that there is only one photo. It is from Northamptonshire, UK, which is Jurassic in age. Thanks.

Ahoi dear forum members. While reading a little bit about rudists some of the structures in picture of a broken Hippurites and the shape of Lapeirusia crateriformis reminded me remotely of a still unidentified beachfind from my last big holiday. That doesn´t say much, as apparently rudist could look like anything they wanted, but still I wonder what the fragment I found may be. Found it in the pacific driftline, broken like you see it. There are some barnacles, some serpulids, maybe a little bivalve also, but I wonder what the enclosing structure is. Any ideas? Aloha, J

Narrative Essay: Resurrecting the Cretaceous
The Amateur Paleontologist posted a topic in Fossil Hunting Trips
Looking through @KansasFossilHunter's blog, I saw one of his posts was a "narrative essay" (you should check it out, it's really good! ). This gave me the idea to write an account of one of my MKFE fossil hunts. I hope you guys enjoy it! Resurrecting the Cretaceous The fine, almost mist-like rain fell gently in sheets and imbued the skin of my face. Despite the lack of intensity, this slow downpour had been going on for the past half hour, and water was starting to seep through my clothing. I was beginning feel very cold. A loud metallic clank (presumably from a hammer) brought me back to the task at hand. I looked around. In front of me, the white chalk cliffs of Møns Klint towered, shrouded in a veil of thick fog. I could hear behind me the sound of waves ploughing through innumerable pebbles of flint. The entire atmosphere felt… otherworldly – I was almost expecting to see the large head of a mosasaur, breaching through the turbulent waters of the Tethys- no, the Baltic sea. Indeed, this cliff was highly fossiliferous – it could almost be considered as some marine “graveyard” from the Late Cretaceous. I got back to work. I was currently excavating a tubular and hollow fossil. At the time, I couldn’t identify it. With the aid of small dental tools, I chipped the soft rock encapsulating the fossil. I felt the fragment come loose, and tensed in anticipation as I gently pried the fossil from its chalky tomb. As I began to safely wrap it in kitchen paper, I looked momentarily back at the excavation site and saw something rather unexpected: the same pattern of the fossil I had just pulled out of the rock. There was more of this fossil. Armed with my small metallic pick, I continued working around the unidentified invertebrate fragment. What was it? Some weirdly preserved crinoid? Focus, Christian. You can ID it later. This was getting very strenuous. The cold, the exhaustion… I toiled on, nevertheless, with grim determination. Shortly after, I got another fragment out of the chalk. This stuff was really brittle, it was already starting to crumble in my hands as I was wrapping it. If only I had taken some PVA. As I thought that that was the end of it, I went back to the cliff wall to gather my tools. I looked back up. Don’t tell me… The fossil was still continuing! Alright then. Time to get out the big guns. Ignoring my family’s requests that I speed up a bit (fossil excavation takes time, alright?), I picked up my hammer and chisel. Small wet bits of chalk flecking my coat, I started hammering off chunks of chalky overburden. I repositioned my chisel so as to slightly modify the angle at which I was striking the rock. I soon saw a thin crack appearing, meaning that the piece of rock containing the fossil was starting to come loose. I gave a few more taps with my hammer, and then pried off the matrix-surrounded fossil. It really wasn’t surprising that there was still more of the fossil in the cliff face. Let’s hope this is the last bit. After all, the visible diameter of this invertebrate seemed to have decreased as I uncovered more of the fossil. Reiterating the work I had been doing up until now, I pried rock from around the “calcareous tube”. Just as I was asking myself if this fossil would ever reach an end, the rock started to come loose. Once the fossil was wrapped in kitchen paper, I looked back at the cliff wall. There was no more trace of the fossil. Finally. I used my dental pick to scrape a bit around, just to make sure. We packed up the fossils and gathered the tools, ready to leave – and say goodbye to Møns Klint I was going to miss that place. Just as we were about to head up the long cliff-front staircase to get back to the parking, my mum picked up a large block of chalk for me to work on – once back at home. Why hadn’t I thought about that before? Safely seated in my parents’ car, I looked out of the window. The atmosphere still felt “prehistoric”: the slight hint of fog, the damp trees shivering in the wind, even the bumpy dirt road… At this moment, I really wouldn’t have been surprised to see a flock of small velociraptorine dromaeosaurs, crashing through the undergrowth and rushing to the opposite side of the road. It was almost as if my fossil excavations had brought back to life animals long gone, from the Late Cretaceous. N. B. Subsequent research indicated the fossil I was excavating was a serpulid polychaete Field photography of the in situ serpulid (in the black circle). The end of a chisel is in the left- 9 replies

I'm not sure, but it almost appears to be two types of Serpula entombed in this nodule. Would anyone agree. Kimmeridgian Kimmeridge Clay UK

Hoping someone easily recognizes these and its an easy answer...my initial searches have been fruitless... So I was supposed to be looking for more Florida coprolites in the garage piles of fossils and got sidetracked looking as this large Turbinella columella and just noticed these tan circular markings on it and wanted to know if they were traces of serpulids? Probably Pliocene Tamiami formation, Sarasota County, Florida. Whats fascinating to me is their spiral?/concentric, ornamented/segmented? shape which appears to actually be etched into the gastropod shell itself. Almost look like cross sections of forams. I've scraped a number of the small white serpulid tubes off thinking I'd see a similar pattern but there is no marking beneath them--its perfectly smooth. If it is a tube, I wasnt aware that they could actually score the surface of the gastropod shell--seems pretty neat if thats what going on but maybe its something entirely different. The gastropod, aside from being badly damaged has sponge borings, barnacle and coral encrustration, and serpulid tubes. Most of the circular traces are around 1mm in diameter and a few push the 2 or 3mm size. Thanks for the help! Regards, Chris

Hello, this time a very mysterious fossil from the Gosau basin of Kainach, Styria, Austria (Campanium). A piece of limestone full of tubes with diameter up to 7 mm. There seem to be a variation of longidutinal ribs on the outside of the tubes. They are associated with one (lowest left) or two Hippuritids. I think these are serpulid worms, maybe genus Pyrgopolon, maybe something near to P. voigti Jäger, 2004. P. regia and P. macropus don´t fit 100%. What do you think? Problem is, I can not find any reference about serpulids from the Austrian gosau basins - ? Thank you very much for your help! Franz Bernhard

I’ve had this serpulid Serpula sulcata for a few months on loan from a good friend. And now after closer inspection I’m quite sure I can see bioimmurations of the hydroid Protulophila gestroi Roverto similar to the picture below. Also indicated by the red arrows in my photo below. Thank you “Bill”….still lot’s more fossils to get through. It’s not that often you get to say “there’s more to this than meets the eye “ Has anyone else rolled the above quote off the tongue before?
