Here are some of the fossils I acquired in a shale roadcut I was told about thanks to @prem. These are ordovician in age, and I have to say it was difficult to collect them due to the fragility of the surrounding material. Ive identified most of my finds, however there were these unusual pill like outlines I wasn't familar with.

Excited to find this fossil-rich rock, which seems to have graptolites (my first). Any thoughts on ID?
Rogue Embryo posted a topic in Fossil ID
It's been a while since I've posted here, but recently I found a small rock that's covered by fossils that are less familiar to me than the crinoids and cephalopods that I often find near Toronto. I think some are graptolites, but would appreciate any help with ID. Thanks very much! -

I found these Graptolites in the Ashgill beds of fine slaty mudstone, at ash ghyll cumbria (You will have no idea where this is) I followed my book from 1969 explaining where to find graptolites. It says these are either monograptus argentus or monograptus fimbriatus ??? Does anybody know what type they are.

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?

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

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

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 fr

Anyone want to trade for some Desmogratus micronematodes (Graptolites)
DevonianDigger posted a topic in Member Fossil Trades Bulletin Board
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- 1 reply

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 e

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 Llanv

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 si -
