  2. Graptolite Display Ideas

    I have been wondering what to do with the graptolites I have found. Currently they're scattered around the house, which I think is a sign to put them up for display. Please... help... the graptolites are taking over my house! How do you suggest I display them?

  5. G'day everyone! I have some beautfiul graptolites from Australia that need a new home. They are middle Ordovician in age and come from Spring Gully, Bendigo Victoria. The small ball shaped graptolites are phyllograptus typus? and there is some unidentified graptolites in the middle on the bottom and to the top right there is a small juvenile Tshallograptus tridens. I am happy to trade all of these graptolites for some other graptolites and maybe some trilobite material? Thanks, Dan
  6. G'day everyone! I was reading through a paper on Bendigonian graptolites and found that their are four similar looking species of Paratetragraptus graptolites that can be found in Bendigo localities (P. approximatus, P. acclinans, P. thomassmithi and P. henrywilliamsi?). I was wondering if anyone could shed some light on the characteristics that help separate and identify each of these species. @Tidgy's Dad? Thanks, Dan

  8. Bendigo Graptolite Hunt

    G'day everyone! Today I just returned from a fossil trip to Bendigo with my dad. We collected at two localities: One in the nearby suburb of Bagshot and the other at Spring Gully Reservoir, next to Bendigo. Most of the Bendigo area is aged Ordovician and the only fossils to be found in this area are graptolites and uncommon phyllocarids . We arrived at the Bagshot site at 10:30 and spend 2 hours digging in a small outcrop on the side of a road. The site was dominated by Isograptus victoriae but Isograptus caduceus and Pseudisograptus gracilis could also be found. The graptolites from this locality are preserved as a white or reddish brown marking. We left after 2 hours to go to another locality we had been to before in Spring Gully Reservoir. The graptolites from this site were more common and more diverse. We did not spend as much time at this site but found more graptolites than at Bagshot. @Tidgy's Dad I may need help IDing some of the graptolites. Here are some photos of the trip: Hope you enjoy, Daniel SITE 1 Pesky meat ants (Iridomyrmex purpureus) All over the site and numbered in the thousands Beautiful sea of wattles Isograptus victoriae (Left) and Pseudisograptus gracilis?

  9. I have a few decent-sized chunks of Desmogratus micronematodes, silurian graptolites from the Rochester shale. They're not super easy to come by, so I figured I would offer to share the wealth. Due to it being summer and me not presently receiving my teaching salary, I have to limit my trades to the US for the next two months, unless someone wants to pay for int'l shipping. Willing to entertain just about any offer, but will give preference to other uncommon material. Photo is an example, I have many pieces large and small. I can take photos of individual pieces based on potential trades!

  11. Hello Everyone School holidays started a couple days ago in Victoria and I started them off with a bang! My dad and I went on a two day fossil hunting trip in Spring Gully and the Mornington Peninsula. The first day of the holidays (Good Friday) we got up around 7 and started the 2 and a half hour drive up to Spring Gully on the outskirts of Bendigo. This site was abundant in Ordovician graptolite fossils and apart of the Bendigonian formation. The location of site was given to us by a fellow member of the NSW Fossil Club. Unfortunately the map they gave us didn't match up and we ended up on a 3km hike through the bush. After some help from a friendly local we were able to match up the landmarks on the map and found the fossil site. There wasn't many rocks to split at the site so we ended up collecting lots of loose pieces along the ground. Overall we spent 2 hours at the site and left with many beautiful examples of graptolites.

  13. Graptolites from Wales

    Quoted from the excellent ukfossils.co.uk website below, to help describe these fossils found forty years ago and currently going through some much needed TLC from team DE&i “These graptolites (pictured above) Didymograptus murchisoni are from Abereiddy Bay, Pembrokeshire in Wales and they are a species known as the ‘tuning-fork’ graptolite. They existed for only a relatively short period of time, during the latter part of the Middle Ordovician, about 470 to 464mya. Therefore, it used as an index fossil for this period of time, which geologists refer to as the Llanvirn stage 9 after a farmer’s cottage on the lane leading to Abereiddy).” Now judging by the paragraph above and the newspaper pages that this large box of shale’s was carefully wrapped in. You kind of get this sense of wonder, for some further interesting, perhaps not so apparent fossils that theses shale’s could contain. I’ve excitedly established that there is indeed hundreds of Didymograptus murchisoni graptolites packed into these shale’s. Continued in reply :

  20. From the album Irish Coral algae and Bryozoan

    Bottom view of a rock found on a beach Co Waterford Ireland. Area is know for mid-Ordovician fossils dating from around 470 million years ago. The rock is 7*19*15cm and when an area approx 2*1*1cm was removed there were fossils found in the area. Quote from GSI "The mix of useful animal groups makes this an important site for biostratigraphical correlation within the Ordovician Period, both in Ireland and internationally. It is even more important because the animal species present at Tramore were biogeographically differentiated into different faunal provinces in older rocks, and the site will be very important in understanding the breakdown of the faunal provinciality within the Iapetus Ocean that once separated northwest Ireland from southeast Ireland. Tramore appears to have been a key site for the early migration of North American species into the Anglo-Welsh (and Irish) area."
  21. Id Please

    Can anyone ID these graptolites for me? sorry for pic. quality, found in Lanarkshire, Scotland. This is my 1st post so it probably won't be right
