K-Pg Boundary Microtektites

Hey, I have one that looks exactly like it, how authentic is it ?

Got it from a UK wholesale. 

Same location, sample, similar pics.

I posted these several years ago. Upon further reading, I now believe most of these are not tektites, purely by visual inspection. There may be a couple to be found, but I've yet to find one that's a good candidate. There are much better examples found in Haiti, and the famed "Tannis" site in ND - which are much more spherical. I've considered seeing if I can get a couple of candidates under a MS to get some concrete evidence. Until then, I'm skeptical.

The rounded elongate object near the middle right of this image does look slimilar to somee microtektites

Yeah exactly, while I'm mostly sure some of them are Tektites, I'm skeptical and would like to know further. 

Let me know if we can obtain samples from Tannis.

I have a Carter county one.

Not sure which one you're referring to, but I dumped what I have out and sorted through it all and found a couple that were vaguely spherical or resembled other forms of microtektites. Part of my skepticism also stems from finding similar-looking material (coal) in Aguja matrix (similar environment); in fact that is my guess for what all this is at the moment. I think some roundness is simply due to conchoidal fracturing.

You will definitely not find samples from Tannis. Besides, it's a scientifically significant site, so I think the samples should be reserved for the scientists 

Sorry not sure why I said right, the object I was referring to is on the left

Ah, that is a pyncodont fish tooth. 

So, I guess the black particles are the microtektites and not glass spherules.

I wish I was there to study Tannis haha
