Oxytropidoceras Posted May 18, 2019 Share Posted May 18, 2019 It appears that people can find Plio‐Pleistocene microtektites associated with and inside closed clams of the Upper Tamiami Formation (Pinecrest beds) of Florida. Maybe enterprising fossil collectors and citizen scientists could look for and find microtektites in other outcrops of Pinecrest beds. The paper is: Meyer, M., Harries, P.J. and Portell, R.W., 2019.

fossilnut Posted May 18, 2019 Share Posted May 18, 2019 Wow How exciting a discovery after the Hell Creek tektite discovery. Forgive my impulsiveness but I have to throw this out there. See my post 02/22/16 Bradenton Beach Shell Hunting page 3. The object is about 1/2 inch so not a micro. Any thoughts? (Sorry I don't know how to post a link to this post) Also see Help ID 3/7/17 additional pictures and info plus comments.

fossilnut Posted May 20, 2019 Share Posted May 20, 2019 Oxytropidoceras Thanks for posting this article. I probably would not have seen it otherwise. I contacted the lead author about my find. Will see if it leads anywhere. Link to comment Share on other sites More sharing options...
Al Dente Posted May 20, 2019 Share Posted May 20, 2019 They look nice but I would hate to pick through several pounds of material that size range to find a few microtektites. Link to comment Share on other sites More sharing options...
HU_Paleo Posted May 21, 2019 Share Posted May 21, 2019 Hi All, I am the primary author on the aforementioned microtektite paper, so please message me if you want a copy or have any questions. There is a lot of potential for this type of work in the shell beds of FL. I very much support Oxytropidoceras's idea that citizen scientists would be great at collecting more of this material. All anyone would need is to collect a gallon ziplock bag's worth of bulk sediment anytime they are in a shell bed quarry. If any of you know of person/org I should get in contact about that, please let me know. Al Dente, I totally agree that these would take forever to pick out of sediment! However, I didn't hand pick these out. The original study was in search of benthic forams and I was emptying my bulk sediment onto a stack of sediment sieves and letting them shake out for 5 or 10 mins (I was a fool-hardy undergrad!). The microtektite material stands out in sieved material. Cheers, Mike 3 Link to comment Share on other sites More sharing options...
