TRout Posted May 30, 2020 Share Posted May 30, 2020 For a couple years I’ve noticed an exposed fossil oyster bed in a creek that I regularly survey for work. Recently, I decided to take a closer look to see if there were any interesting fossils besides oysters and found several shark and ray teeth weathering out of the bedrock. I believe these fossils are part of the middle Eocene coldwater sandstone, found in a creek in Southern California’s Conception Coast. I haven’t been able to find much literature describing the fossil shark species found in this formation so I’m not going to try to ID them just yet. 1 Link to comment Share on other sites More sharing options...

siteseer Posted May 30, 2020 Share Posted May 30, 2020 That rock looks harder than the shark teeth. It will be tough to get some decent specimens unless you can break down the matrix somehow. I don't see any obvious Eocene teeth in the photos but then they are a bit weathered. They appear to be sand tigers and/or early makos plus at least one myliobatid tooth. Offhand, I can't think of a paper on the Coldwater Formation. I don't recall a paleontologist mentioning it but can see if I have or can find anything on it.

JBMugu Posted June 4, 2020 Share Posted June 4, 2020 Interesting post, I have heard of people finding teeth in the Cachuma Valley. I wonder if this is the same formation? Link to comment Share on other sites More sharing options...
