I am looking for sedimentary formations, where can be found Cretaceous to tertiary fossils in South Korea. I am especially interested in molluscs and bryozoans. Thanks for help.
You need to cross check references to see fossils you are looking for. Also if you are specifically not interested in marine sedimentary sequences, the link provided would provide some fossil clues:
What do you mean that you need marine sediments? The tectonics and sedimentary facies constraints in South Korean terrain do not permit occurrence of fossils you are looking for and during the time slice chosen by you. Your question asks for more clarity.
There is no Cretaceous marine sequence in Korea. All sedimentary rocks developed in Cretaceous of Korea are fluvial to lacustrine sediments deposited in backarc or pull-apart basins.
However, thick sedimentary deposits of Miocene age developed along eastern coast of Korean Peninsula. Please search for "Pohang Basin". These sedimentary sequences were deposited as Gilbert-type fan delta, and therefore yields marine fossils. I know of some papers describing molluscs, but not of bryozoans. All of these papers are written in Korean, and there was no study on these molluscs in recent 10 or 20 years, as far as I know. The most recent review would be:
Lee, Y.G. and Yoon, S., 2004. Cenozoic bivalves and gastropods. Journal of Paleontological Society of Korea, Special Volume, 217-224 (in Korean with English abstract).

Great, many, many thanks Jeong-Hyun! It is exactly what I want to know. Do you know, if the sections (locality, side) are still accessible? Are there any possibilities for recent collecting? I am almost sure, if there are molluscs, the bryozoans will be there! Just nobody jet searched for them…
Please contact me directly to [email protected] for further information. Once more, many thanks and looking forward to do something togetherJ
I am sorry that I cannot be very much helpful; I am a Paleozoic guy, and do not have very much interest in these "young" rocks. You may contact Dr. Chang Woo Kwon or Prof. Young Kwan Sohn, who are sedimentologists recently worked in that area. Please check attached publication for their detailed information.
