My name is Joshua Vise. When I was a child and teenager, I loved collecting fossils from outcrops near the my home in Missouri, not too far from the banks of the Mississippi. I have since moved to South Korea, and thought I’d restart this hobby. However, I am faced with a problem that I hope you could help me with. In the USA, I never learned really to identify rocks because the exposed outcrops where I would hunt for fossils were all sedimentary, with lots of shells and crinoids. In Korea, many areas are more forested, and sedimentary areas are intermingled with granite and other igneous formations. I am able to distinguish sedimentary rocks from igneous and metamorphic rocks, but I’m unable to really identify what kinds of sedimentary rocks may be good sources of fossils. Most online resources are a bit redundant (saying something like “If fossils are present, it is sedimentary”), or don’t do much to help me identify these types of rocks in the field (saying things like “Fossils can be found in shales, limestones, and mudstones"). Moreover, I am not sure that a field guide to rocks printed in English would be relevant here, because most of the field guides I have seen deal with North America. My questions for you are: 1. Is there a reliable way to identify shales, limestones, and mudstones just by sight? Are there consistent colors, textures, or shapes I could look for? Are there any tools or techniques that can help me? 2. Are rocks of these types consistent enough that a field guide to rock identification for the USA would be useful in Korea? 3. Are there any other resources you could suggest? I am definitely an amateur, but am always looking to learn.

This trilobite is Dolerobasilicus yokusensis. It's the only trilobite found in South Korea, Jik-un Mountain Formation. It's really hard to find a completely preserved. Unfortunately, Most Korea's fossil sites are being destroyed, and it's becoming increasingly difficult to obtain and scarce...

Hi guys, This is my 1st post(Execpt introduction)! I went to fossil hunting at June 5th and 6th to Gangwon-Do, Republic of Korea(South Korea). It was my 2nd geological exploration. Location information : 1st site - Jangseong, Gangwon-Do, Republic of Korea(South Korea) = Jiggunsan Formation(Jigun Mountain Formation), Middle Ordovician <Figure 2> 2nd site - Sesong, Yeongwol-Gun, Republic of Korea(South Korea) = Jiggunsan Formation(Jigun Mountain Formation), Middle Ordovician <Figure 3, 4, 5> I rode a bike to get there about 110 km(Actually 50 km. Including returning distance is 110 km.) and there was a lot of bugs like flies or mosquitos etc. It was very hard journey but it was very nice too. This picture took at the first fossil site.(Actually, before arrive at the fossil site.) The first fossil site was easier to access than the second fossil site. \ Actually, I couldn't find the second fossil site. I heard that veeeeery many fossils are there(Trilobites, Cephalopods, Gastropods, etc.). However, it was too hard to get there. Forest was too thick to access! So, I couldn't find the actual fossil site, but I found a pile of black shale. Probably it exposed the tip of the formation or crumbled and moved from the site. Anyway, I didn't have much time at that time to investigate arround there. I hope to go there again in order to investigate someday! I collected 88 specimens there.(Except donation. I donated about 27 specimens to national museum.) I could find a lot of trilobites and gastopods. I couldn't find a complete one, but I found sub-complete trilobites and its eye lens are completely preserved. Also, I found complete ventral cephalon of trilobite. Its hypostome is very good conditon. I found this one at the 1st fossil site. And, I found a lot of trilobite hypostome at the 2nd fossil site too. Left side - Excavated at 2nd fossil site Middle side - Excavated at 1st fossil site Right side - Excavated at other fossil site. It's plant fossil. I found them in a pile of coal muck. It's Gangwon-Do too. * I'll update fossil images after this post. I resized whole, but I think that the data is not enough to upload whole images here.

This is a fossil whale tooth from Pohang. It was discovered at an apartment construction site in Jangryang-, Pohang. Currently, most fossil production sites in Jangryang-, Pohang, have been destroyed by construction. The fossils are fossils that were discovered while construction was in progress. It is a sperm whale's tooth fossil, and the jaw bone may be in the mother's rock, but it is not observed. (It seems unlikely.) I try to do it. Growth line is indicated by dots. In addition, the growth line can be observed through the cross section of the tooth. About 10 growth lines were observed. (Usually, small toothed whales are said to be the teeth of mature individuals when there are 4 to 8 growth lines.) There are fragments of sea urchin fossils on the back, and tooth fossils of a tiger shark. Personally, I think it's a precious fossil than Megalodon in Pohang, but I'm very satisfied with the collection.

Could you please identify these fish fossils?

Hello! It's been a loooong time guys! I'd like to introduce some Korean trilobites to you and share some of my experience in fossil hunting in Korea(South). I went to Gurang-ri[GuRang-ri], Mungyeong[MunGyeong], Northern Gyeongsang-do[GyeongSang-do] on June, 23th, 2017 for hunting trilobites. (By the way at this time, I went there by in my brother's car, finally! I practiced a bit after I had gotten the driver's license. Maybe I'll go to Jiggunsan formation on December in brother's car, again! *:D*) Anyway, I found the location and some information from a dissertation, which was posted by a high school teacher(it was written in Korean. Maybe if you can speak Korean, then I can share it :)) The teacher found 2 kinds of specimens from different formations. One is Gurang-ri[GuRangRi] formation and the other one is Hanae-ri[HaNeRi] formation. One is "Kootenia amanoi Kobayashi, 1961" and the other one is "Redlichia nobilis Walcott, 1905". Actually, I was going to go to Jiggunsan formation 'cause that site's fossil output is better than Gurangri formation. You know, I had hit the rocks for about 2 and a half in the strong sun(at that time, the temperature was around 95°F(35°C)) and I found just 7 specimens. On the other hand, I found about 60 specimens in 2 and half hours in Jiggunsan formation. I grabbed the steering wheel with excirtement The quote from Robert Stevenson crossed my mind at that time: "To travel hopefully is a better thing than to arrive". Before going to the fossil site, it was really excited. But I thought that I would trembke with excitement if when I could meet some trilobites so much so that when I encountered faint galaxies or stars through the telescope. (Highway rest stop. The big words(충주휴게소) on signboard means Chungju[ChungJu] rest stop.) When I got to this rest stop, I reminded that I forgot to take mosquito repellrant. So I bought a new one and had blunch from near here. After arriving at the fossil site, I couldn't find the actual formation. With perplexed feeling, I just knocked this seems similar sedimentary rocks which depicted as red-purple colored layers. *Gurang-ri[GuRang-ri] formation And I found something strange structure. I thought that it was some strange metamorphic structure or bivalve fossil. However, after took a closer look, I felt something is strange and finally I realized that it was trilobites' head shield! The images are Redlichia nobilis Walcott, 1905 I took these pictures when I was in my country. So, I couldn't change the coin to other countries' coin or ruler. Its size is almost 1" or 25 Canadian cents. Redlichia's cranidium. Thorax part. Another cranidium preserved as cast(positive). This one is mold part of the above image. One part of thorax. Not that good preserved but still can see some glabella. Cranidium and librigena(free cheek) Librigena(free cheek) and strange fossil cast part. Mold part. Librigena(free cheek). Strange fossil. I don't know what it is. Thank you for reading this long post! Next time, I'll update fossil hunting at Humber river, Toronto, Ontario. And Brechin quarry and Bowmanville quarry. Thankfully, Joe from Michigan will take me to there! I REALLY appreciate it!

Hello Saero gaip ha n i'm korean. As a korean, l am poor at English. I'd appreciate it if you could understand that (In fact, this is a translator...)There may be a lot of misinformation. And l'm honored to be with you Thank you.

I think the first one is maybe chestnut tree's leaf, second one is the willow tree's leaf, and last one is also chestnut trees's leaf. But I can't sure right id. Because these plants are looks really close other specimens. I really want to know these fossils right id, please.

Here is a nice plant fossils! there are all from South Korea. I interested for mammal and dino's bone and there teeth, and amber.
