Hello fossil experts! I am an underwater documentary filmmaker based in China. I came across a fossil wall in the underwater karst cave systems of Guangxi province this year and am hoping you can help shed some light on them for me, as I am admittedly not a fossil expert in any way.
The fossil wall is approximately 25-40 meters underwater in the freshwater limestone cave systems in the mountains of central Guangxi province. I have not attempted to count them yet, and as far as I know no one has studying or catalogued them. The cave is well known in the cave diving community of China. But, as you can imagine, this is a pretty small community.
I would appreciate any help identifying the type of fossils they may be, and any relevant information on approximate dates or the way in which they would have arrived in these cave systems. As I said, this in not my area of expertise, so all information is useful!
(I am having attaching the photos with this post, so will attempt to post them separately)
Thank you!
