Howdy yall yet another great day on peace river. How blessed we are to live in this part of the world. Well, i started my day at Publix, then headed out to the grounds. I ended up finding a couple mystery pieces today, a bunch of sharks teeth, some turtle shell and what i think is a gator jaw bone. The day was cut somewhat short by a nasty little thunder storm. Was also approached by about an 8' gator, he didnt think i looked tasty apparently and moved on lol.

I came into a rock and mineral shop in Northern California and looked around. I saw this on display and bought a few pieces. Is this actually petrified wood struck by lightning? Does anybody know the provenance of this fossil (it wasn't specified). Thanks.

Hi All, Yesterday I had the opportunity to go fulgarite hunting. For those who are not familiar with the term, a fulgarite forms as the result of a lightning strike on quartz sand. I'm sure that some in this group will contend that a fulgarite is not a fossil but others consider it as evidence of a lightning strike. The only problem is that it is very difficult to date a fulgarite. Anyway, check out my photo below and I hope that you like what you see.
