Identifying Fossil Bearing Sedimentary Rocks in South Korea
joshuavise posted a topic in Fossil Hunting Trips
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.- 5 replies

I would like to get started in Micro-paleontology. At this time my assets are a modest 20x-40x stereo microscope, curiosity, and now that I am retired, time. I am working my way through this discussion forum and find it fascinating and exciting. What are good samples for a novice to get started with? Are there good places to purchase samples? I would like to learn to prep the fossils myself. Any advice to get me started would be greatly appreciated.

Hey all, I've recently caught the "fossil bug", and I have been looking at geologic maps online to help determine potential hunting locations. Is anyone aware of an exhaustive website, book, etc. that labels stratigraphy? If not, what do y'all use to determine the age of certain locations/formations? Any advice is appreciated! Thanks, Caleb

Hello I found a very distinctive belemnite while fossiling on Friday, and want to learn to identify the species myself, and hopefully identify all of the more complete ones I have collected. I used this resource http://www.bgs.ac.uk/discoveringGeology/time/fossilfocus/Belemnite.html to classify its features, and looked at Fossils of the Oxford Clay by Martill and Hutson to try and find it. Unfortunately only six species are identified and this isn't one of them. I looked in British Mesozoic Fossils from the Natural History Museum, and while this has Jurassic Belemnites, they are too early. Trundling around online hasn't gotten me any further. I'm trying to be more systematic in learning about my fossils, and was wondering how others approached first learning about specific species, and if there are any resources you would recommend? And if anyone knows of a monograph on Oxford Clay belemnites, please let me know

What's the 'must have on your shelves' literature on European ammonites particularly for accurate identification? Cheers John
