jgcox Posted March 20, 2014 Share Posted March 20, 2014 Finally got my camera from AM Scope while it works great the magnification is way too much. So I bought a digital microscope with less magnification. I had posted earlier that I had found microscopic sphericals with what I believe to be shocked quartz. Which could indicate an ancient impact I got a photo of a few of these. I also have a photo of a tooth that I can not ID and a pic of some microscopic SD gold. I will add more pics soon.

Scylla Posted March 20, 2014 Share Posted March 20, 2014 Nice pics! I saw one of those spherules once in some Potomac river marix, but it rolled away when I breathed near it! So be careful with them. Link to comment Share on other sites More sharing options...
Auspex Posted March 20, 2014 Share Posted March 20, 2014 A technical question, if I may:if the spherules are once-molten impact ejecta (and this is the only way I can think of that they could have assumed a spherical shape), then would they still show the microscopic tell-tale of having been shocked? The gold is pretty neat!

jgcox Posted March 20, 2014 Author Share Posted March 20, 2014 Auspex No the sphericals do not show being shocked The fact that I found them along with Cosite (shocked Quartz) makes me think somewhere near this location an impact could have occurred. There are lots of spheres in the loose soil Trevor sent and even some imbedded in matrix. I have taken some samples and will take them to the geology dept at U C for an ID. hopefully someone will know what type of tooth number 3 is.

squali Posted March 20, 2014 Share Posted March 20, 2014 Could you post some pics of the Cosite showing the fracture patterns? It's hard to remember why you drained the swamp when your surrounded by alligators. Link to comment Share on other sites More sharing options...

jgcox Posted March 20, 2014 Author Share Posted March 20, 2014 Thanks Marco and Squali I will get some photos of the cosite Link to comment Share on other sites More sharing options...
jgcox Posted March 20, 2014 Author Share Posted March 20, 2014 Pics 1 thru 4 are of cosite--5 & 6 are unknowns 7 is a view of pieces picked out of matrix 8 is an unknown & 9 I believe is a tooth Link to comment Share on other sites More sharing options...
jgcox Posted March 20, 2014 Author Share Posted March 20, 2014 10 is a tooth in jaw bone 11is unknown 12 I believe is squaliclorax and 13 is unknown Link to comment Share on other sites More sharing options...
squali Posted March 21, 2014 Share Posted March 21, 2014 Hey JG #6 looks like possibly enchodus. If the root side is somewhat 3 sided.. Your right about #12, squali. Opposite angle could tell species. I'm having a tough time seeing the shock laminae in the quartz. I would expect to see fracture lines running at angles to each other.

jgcox Posted March 21, 2014 Author Share Posted March 21, 2014 probably need more magnification I can try under 400x Link to comment Share on other sites More sharing options...
MarcoSr Posted March 21, 2014 Share Posted March 21, 2014 9 is a Ptychodus and 11 looks like the crown of a Ptychodus whipplei. Marco Sr. "Any day that you can fossil hunt is a great day."

MarcoSr Posted March 21, 2014 Share Posted March 21, 2014 Thanks Marco any idea what #8 might be? Nothing specific comes to mind for #8. Maybe a picture showing the entire specimen by itself might reveal something in the overall shape. Marco Sr. "Any day that you can fossil hunt is a great day."

MarcoSr Posted March 21, 2014 Share Posted March 21, 2014 This one Oh, I was looking at #10. Unfortunately can't help with #8 either. Marco Sr. "Any day that you can fossil hunt is a great day."
