Took me a little while to post this trip report, I'm always a busy person. This trip is from October 3rd, 2020 in Ellsworth County, Kansas at a reservoir. The predominant formation at the site I visited is Kiowa formation; which is known for marsh and delta environments in the early Cretaceous (Albian). I found some interesting things and I'll show below. Possibly some carbonized wood materials. Lignite or coal? It was flaky and would crumble if touched. It left some black powders on my hands after handling it. I found several large pieces of them together and partly encased in concretions. Putting them together would make them about a meter and half long. Piece #1: Piece #2: Backside of #2. Notice the clutches of concretions. ...continued on the next post.

So I found this stone at Lake Memphremagog on the Vermont side and it looks like wood and feels like wood on one half but on the other side it looks like fossilized wood and the stone/fossil itself is heavy like stone and cold to the touch like stone so it is definitely not entirely wood. I’m wondering if it is just partially fossilized or something but I’m also curious if 1. It actually is a wood fossil and 2. If there’s any chance anyone can tell how old it is by the looks of it. Thank you in advance even if it turns out to be just a very cool looking stone. I’m happy to provide any additional information of needed!

Petrified Wood - Is it real?
Seguidora-de-Isis posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hello good morning to all! I'm thinking of buying this supposed fossilized tree trunk from a Chinese who claims this came from Madagascar ... I'm worried because I can not see growth rings and pronounced tree shells on the trunk. Is it real? Thank you all for helping me. -
Hello there, as in the title -does anybody knows if it's valuable or not? The certification centre told me that in their opinion its even 300mln years old+ but to state that they would have to run some expensive tests. Its most probably digged up from 100 meters under the ground in Syberia. Thanks for any help.

I am not entirely sure where petrified wood fits in the fossil domain, but here is a sampling of some thin sections I made from a sample from the Rock Shed.(http://therockshed.com). The sample was cut in four slices, two cross sections and two transverse sections. One of the cross section slides broke into several pieces when I used too much force removing it from the polishing holder. The petrified wood is not very birefringent so the photos were taken with Plane Polarized light. A presentation showing more images may be viewed at The wood fossil is from The Rock Shed Photos 3 and 4 are full size, approx. 26mm, scans of the transverse thin sections. Photo 5 is a full size, approx. 12mm, scan of a cross section. Photo 6 at 25x of a transverse section.

Last month, my husband found this piece labeled "Hematite After Wood Minnesota" at a rock shop. The piece is about 7 cm long by 2 cm wide between the bulges. I have some doubts about the "After Wood" part of this label. The bulges look more botryoidal than barklike, and I don't see any distinctive woodlike structure on the broken ends. I could easily be wrong, though. Here are some better-illuminated pictures: Do I have a really cool mineral replacement fossil here, or a really wild-looking pseudofossil? If the former, I'll include it in my mineral club open house display this Sunday. If the latter, I might include it in a mineral club display on pseudofossils next year!
