Hello everyone!! I feel very lucky to belong to this forum, I never stop learning and the atmosphere is great, I only regret not being able to contribute more than praise for you! I have a query, I have seen some marks on shark teeth (Megalodon, Miocene), which remind me of annelids, Is what I'm saying crazy or does it make any sense? Cheers Manuel

I was once a teaching assistant for a Diversity of Life course and it really left an indelible imprint on my awareness of diversity in general, as well as consolidated my fondness for all living things that began in childhood. It's incredible how successful the "worm" body plan has been and how this has been such an integral bauplan since the earliest phases of animal life. Being a bilaterian essentially equates to a wormy relative (i.e. acorn worms for we deuterostomes) so in honour of that on this auspicious hump day, please share your worms - the more priapulid the better I'm

My mother accumulated some fossils during her teaching career in Louisiana. At one point...probably 50 years ago....they were sent to LSU to be identified. Over the years, some of the labels have been lost and I've recently gotten the identification of most. But this one is still "up for grabs"...the original label said "annelid?" Any help would be appreciated....I'd like to get them appropriately displayed....for some reason someone thought it was a good idea to glue them onto styrofoam.

I found these on a beach in Illinois in a small lens of pyritic sand. I believe they are worm tubes but not entirely sure. They are only visible under microscope and occur with pyrite framboids. So my question is, are they indeed worm tubes, pellets, or something else? I can only assume they occur at the beach because of erosion of Silurian rocks placed there, but not sure of that either. In this pic below, you can see partially inside the tube which features spheres of pyrite. It's my understanding can be produced by worms.

Ok- so I was 13 when I found this one in south St. Louis county, and I thought it was an annelid, then an insect (thought there was a leg -there was no difference between 12 and 13 ? ). This is very similar to the last post i just had, thanks again! Bone

I have noticed lately that a lot of fossils of so called Sabellidites cambriensis are popping up on a lot of sites for sale. They're sold as basal annelid worms that arose during the terminal Ediacaran. They predominantly are coming from the Lontova formation, dated at ~541-545 Mya, which is more or less the Ediacaran/Cambrian boundary. I would think that such fossils would be of great interest to researchers since, assuming they are basal annelids, they would represent one of, if not the first, appearances of a modern phylum in the fossil record. Yet the literature on this species is very spa

Hiya, had this fossil for a few months now and i've been wondering what it is. My geology teacher seems to think it is an annelid worm but i'd like to know a little bit more. Thanks. Date: 27th November 2012 Location: Whitesands Beach, Pembrokeshire. Rock Type: Limestone Rock Age: Cambrian (I think) Dimensions: 4.8cm x 0.5cm #1 #2 #3

I found this at St. Clair in a pile of small rocks and boulders on top of a hill at the fossil fern site at St. Clair PA - obviously these are not Pennsylvanian swamp fossils - I believe this was part of a load of older rocks and boulders dumped there from when this was an active mining pit. The rock is hard sandstone or silicate - burrow/fossil was replaced by quartz). The tunnel or fossil starts on one side and makes a U-shape to the other side. One side looks like it is filled and the other side looks hollow. I've found other specimens showing the same pattern, as well. Update (26 Oc
