A nice Dictyonema flabelliforme dendroid graptolite from Oslo Fields in Norway. It's Tremadoc, Lower Ordovician in age and is thus maybe around 480 mya. Another angle :

Hoooooooooooorrrrrrrrrrrraaaaaaayyyyyyyyyyy!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Here we are at last, into Adam's Silurian. Thanks for looking. First up is the Lower Silurian or Llandovery and I begin with a problem. I posted this one incorrectly in Adam's Ordovician as it had got it's label muddled up with an Ordovician Favosites I had that has vanished in the move here, but is being replaced by kind forum member @Herb Anyway, this, I remember now I've found the correct label, is from the greenish Browgill Formation, part of the Stockdale Group from a cutting near Skelg

This graptolite is of Silurian age and is from the Rochester Shale, near Buffalo, NY. I hope someone knowledgeable about Paleozoic sea floor bric-a-brac can tell me what species this is. The main cucumber shaped colony is about 12 cm long. I'm guessing that this is in the genus Dictyonema, maybe Dictyonema crassibasale. but I'm no expert on this.

I found this small specimen in the Platteville Formation (Middle Ordovician) in Wisconsin. My first reaction was that it might be a graptolite fragment, especially as it looks to be preserved as a carbonaceous impression. However, I would appreciate a second opinion. Thanks!

Yesterday I hunted for about 6 hours in Breckenridge Texas on my way back to Lubbock. Although I found no trilobites, I’m certainly glad I went. I found this graptolite and was wondering if anyone could help with further identifying, identified as graptolite because of the small “hieroglyphics” on the shell. Love this thing!!

Hello all. I was wondering if anyone would perhaps known enough about graptolites to possibly be able to tell me a little bit more about the specimen pictured (if the picture allows, what species perhaps)? I found it years ago when collecting fossils on Manitoulin Island (about 1.30h from where I live in Northern Ontario) if this helps at all.

I enjoyed an autumn drive through the rusty-red-colored oak forests that blanket the scenic mountains of northeast West Virginia. Two inactive quarries enticed me to prospect a bit. In the first quarry of Ordovician age shaly limestone was this graptolites plate .... perhaps Climacograptus? In the second quarry of early Devonian age massive limestone was this crinoid column base with the attached holdfast. Both specimen photos are as found.

I was recently reorganizing my fossil collection and thought I would share some pieces I collected during Paleontology field trips in undergrad at Alabama. I'm glad I took thorough notes at the time! The demopolis chalk is a popular formation for finding Exogyra/ostrea/pycnodonte shells and shark teeth. We visited a site in Tupelo, MS many times for surface collecting. Some of the cool pieces I found were many fragments of a mosasaur jaw (top pic, top 2 slots), a Squalicorax kaupi tooth, a scyliorhinus(?) tooth, bony fish vertebrae, and bony fish teeth. I was told the dark fossils

These two finds are stumping me a bit. Both are from the Maquoketa Fm (Upper Ordovician) of Iowa. The first one initially struck me as a 3D graptolite, but it could be a crinoid stem. I couldn't get a good photo of the cross section, but it is rectangular.

Last week I visited a silurian site and found this stone. I wonder which kind of animals this is? And which kind of stone, which is blue inside with a relative thin layer of white material on the surface. The animals are "printed" on the surface. Martin

Hello Found some I believe to be Graptolites and would like to be able to ID them better in the field. Is there a guide available or even a good book anyone might recommend for this. Attached pictures are what I think are graptolites but would like to verify. Surface finds Thank you all for the help Tom

This was found in Maine, but was likely brought in as crushed rock from Quebec by a Canadian railroad company. Dendroid graptolite is my opening guess.

I have two items on which I am requesting opinions. These are from a dolomitic nodule from the Schoolcraft Fm. in the upper peninsula of Michigan. The first one I think is a pygidium of the trilobite Scutellum. (note there appear to be some other trilo"bits" surrounding it). @piranha, what do you think? Here is an image from Ehlers (1973) Stratigraphy of the Niagaran Series of the Northern Peninsula of Michigan that he has as Scutellum laphami.

Locally, graptolites are very common in the Maquoketa/ Ordovician rock. They present themselves as 2 dimensional creatures on certain bedding planes. Below the Maquoketa is our Galena. It has graptolites but uncommon. Again, they present themselves as 2 dimensional. The "unknown" specimen from the Galena, presented today, is obviously 3 dimensional and I venture a guess that it is a Graptolite. But I thought I would seek opinions in that I have seen thousands of local graptolites but never one that is 3 dimensional. Could it be something else??

Hello there! Well, I tried to take Viola out for a little fossil hunt by Mimico Creek in Etobicoke, Ontario (Georgian Bay Formation, Upper Ordovician) this afternoon because when I checked the forecast this morning it looked like it was going to be ideal fossil-hunting weather - a mix of sun and cloud with temperatures in the mid-20s Celsius. When we arrived, however, it began to rain - we toughed it out and came away with one piece before it began to pour and we called it a day. I was disappointed since I was hoping to spend a few hours there, but the one piece we took home look

I had a chance to stop for a half hour at a roadcut near wax, ky to look for blastoids. While i didnt find any of those, i did find a cool bryazoan, another creature that may be a kind of graptolite, and a silicified section of crinoid. Thanks to those of you who helped me find the area... it is pretty cool. Sometime i'll be able to spend more time there, and i'm already looking forward to it.

G'day everyone! I have recently returned from a trip to NSW where I did a bit of collecting in exposures from the Gunningbland Formation (450 Million Years Old). I found this fossil on the last day of the trip and at first thought it was a bryozoa. Though, after a bit of observing and some comments from members of the forum, I believe this could be a dendritic graptolite? Graptolites have been recorded from the formation but I have not found any information on dendritic graptolites from Gunningbland. Any help would be much appreciated. Thanks, Dan

Dear all, I recently went for a trip to Wrens Nest and found this small, what I believe Dendroid Graptolite. It measures ~2cm (apologies for the poor quality of the image). If anyone could suggest a Sp. ID, or even if it is a Graptolite that would be very much appreciated. Thanks, Tom

Was digging around in some boxes and found this specimen... it has a decent number of species on it! Although its nothing compared to another plate found at the site by some friends. We were going to split it but decided not to. Ended up having a couple hundred individual graptolites inside... but anyway! Sorry about the horrible pic as per usual. Early Ordovician (Bendigonian Stage) Bendigonian Formation, near Bendigo, VIC Australia.
