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 :

Hello guys and girls, I'm new here :-) Could you help me identify these fossils. They are all from my local city of Porsgrunn, Norway. I gathered these over the cause of a few days due to construction work, so I saved them before the whole area is buried under tons of rubble. The first fossil (1-2) around the size of a finger, the "branch" was much longer before I broke it lose, around half a meter. Image 3-5 is the one I am most curious about, could it be a trace fossil of some sort. It's embedded in the shale, some of the lines are 0,5 cm deep. From what I know Image 6 is most likely a Ragusa coral, and Image 7 is probably Stromatolites. The last fossil looks like it fell out of a geode at some point. :-) Most of the local fossils here in Porsgrunn can usually be dated to the Ordovician or early Silurian and they are relatively small in size. Porsgrunn in Telemark is a part of the Oslo Geological Field in Norway, which is a part of the Burgess Shale. The fossils in the Oslo Geological Field can be dated to around the Precambrian era to late Silurian. Thanks :-)

Hi, I have this rock I found with what seems to me to be several different fossils. I have numbered them in red. One and two seem to be shell, but not sure if 3 and 4 is anything. If someone could give me a tip on weather or not it would be a good idea to try to see if I can get some rock off with vinegar. I think number 3 looks especially interesting. Cant wait to hear some opinions
