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.

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!
