Auspex Posted July 29, 2019 Share Posted July 29, 2019 In 2006, University of South Florida student Mike Meyer found the beads during a summer project in the field, working with Florida Museum of Natural History invertebrate paleontology collections Director Roger Portell.

digit Posted July 29, 2019 Share Posted July 29, 2019 Very cool! The first microtektites in Florida and possibly the first found inside fossil shells. Cheers. -Ken Link to comment Share on other sites More sharing options...
Al Dente Posted July 29, 2019 Share Posted July 29, 2019 This article was brought up previously here. Some friends have been discussing this paper recently and one pointed out that the glass beads have the exact same chemical characteristics as reflective glass beads sold for use in paint for road center and side lines.

snolly50 Posted July 29, 2019 Share Posted July 29, 2019 I have just emailed the paper's author, including photos of minute glassy spheres I had previously encountered in sorting Hawthorn Formation micro matrix. I am curious if he will see similarity to the material he was working with. 6 hours ago, Al Dente said: reflective glass beads Do you know if the manufactured beads are of a uniform size?

DPS Ammonite Posted July 29, 2019 Share Posted July 29, 2019 Here are pictures of manufactured glass beads:http://www.landscapusinc.com/TT-B-1325D-Type3-Glass-Beads.html Most natural glasses/ tektites that I have seen are dark or green. I would guess that clear ones would be more likely man made. My goal is to leave no stone or fossil unturned.

snolly50 Posted July 30, 2019 Share Posted July 30, 2019 2 hours ago, DPS Ammonite said: pictures of manufactured glass beads Excellent, your post and image answers the question about uniformity of size. It's easy to see that the man-made varies just like the spheres I recovered. However, some do not (at least in the image above) have that fused together appearance of two relatively equal sized spheres; nor do I see a sphere with even tinier hemispheres attached to its surface. Both of those conditions are extant in the Hawthorn material I found.

HU_Paleo Posted August 5, 2019 Share Posted August 5, 2019 Hi All, I'm the lead author of the 'Possibly Micro-tektites' paper mentioned above (let me know if you want a copy for educational purposes). We were all very concerned w/ contamination and this was brought up with the editors and reviewers during the publication process. The big sticking point is that we found these within articulated bivalves, and no one has been able to explain how they could have gotten in there (other than a general 'contamination'). However, till we find more of these materials at other sites, contamination is still a possibility. If anyone is collecting in a quarry and sees some sediment filled articulated bivalves, I'm always looking for more materials! Cheers, Mike 2 Link to comment Share on other sites More sharing options...
