I think that first one is palm root. Possibly fern root. The third one is like nothing I have ever seen. Looking forward to an ID on that one. It seems to be a cross section of a complete organism. Like a sponge or whole coral head. mushroom ? The round top sure looks like it is designed to take in light.

First one is classic palm root. Second are pyrolusite dendrites but are not fossils but rather crystalline structures. Third one is very cool but has me stumped. Looks woody but I don't know......Mel

They're all superb, but the third one tops them all!

I'm seeing a blue art glass candy dish for the third. I could be wrong, but I have seen similar organic patterns used. The dendritic stone is really nice. The dendrites could indeed be iron-ic, as in the German dendritic limestone, or manganese-based, as in the Utah dendritic sandstone.

Thanks, everyone for your input, id's, and kind comments! Sabre52, my better half thinks the last piece is a piece of petrified wood and think it has opal in it. I'm wondering if it may be petrified swamp bog or peat? @rocks2dust kindly sent me some links to check out of the different types of art glasses that look like minerals and fossils, so I believe he may be on to something when it comes to id'ing the last slab. I think I'll post pics later of the edges of the piece. Kevin mentioned that in the photos I took of the last specimen, the edges look fire-polished and have eroded edges, which is common in art and commerical glass. (think I said all this correctly...) I think I'll keep most of the slabs for displaying, kk. There are a few he kindly sent to me that I may cab, though. I got kinda tickled that he called one piece 'wonderite' (wonder if it's this or that), that I believe is a slab of nuundortite (spelling?). If I remember correctly, the slabs were purchased from a couple that were living in a teepee somewhere in California, rockpickerforever. The girl wanted the guy's rocks gone. The friend that sent the slabs to me is a retired geologist and sells his pretties on the Salt River Collectables website and ebay (saltrivercollectibles).

Been digging through all my petrified wood books, especially the two Daniels volumes and I'm thinking more and more that fancy pic is a pet wood cross section. ( I love a puzzle! *L*) Lower right hand of the slab actually has the look of a couple of branches or buds coming off the specimen. Daniels' first book shows some very similar fan patterned Mesozoic woods but they are labeled as "unidentified". His second volume which is huge and much more comprehensive, shows several woods with those fan like patterns. Among them are specimens that are primitive sycamore types and Schilderia and star Dadoxylon. I'm far from an expert but am thinking the specimen pictured is at least "pet wood". You might see if you can find his Ancient Forests book in your local library if you don't want to spend a bunch for one, and have a look at the picture ID section which is incredible. So many wood types have never been identified, especially the older types which represent extinct or tropical woods but that fan pattern sure looks organic/ wood in origin to me....Mel
PS: Did some more research and it could be a cycad or cycadoid transverse section too which would explain those bud looking areas. This looks to me to be the closest, most likely ID.

Oak out of Oregon w/radial outward lines. Not very similar though

The first two are palm rhizomes (root) from California. Look up Edison palm or Mohave desert palm for more pictures to compare. The last piece is a transverse cut of wood and from the Hampton Butte area of Oregon. The last picture is the best as it appears to be ring porous and possibly sycamore or beach. I would have to have it in hand to be positive.

Thank you, Sabre52! I greatly appreciate your detective work and suggestion for checking out further information on the slab! Will see if our library system has a good book to read for reference. I googled cycad fossils and found a couple of photos that I wanted to share. Cycad fossil Source: Davesgarden.com Source: Davesgarden.com While searching for information that Mel suggested, I read that there was a Fossil Cycad Monument that was destroyed by vandals. en.wikipedia.org/wiki/Fossil_Cycad_National_Monument @rocks2dust suggested that I scratch the slab with sunstone. I performed a scratch test on both sides of the slab with a tumbled piece of sunstone. The sunstone did not scratch the slab on either side. Thank you, jerrys, for your id's! That's pretty cool that the last slab may be Hampton Butte pet wood! I'm cabbing a piece of the seafoam-colored Hampton Butte pet wood. Here's a pic of the slab: Hampton Butte pet wood near center

I think jerrys may be onto something, have a look at some of these image search results: I agree John Herchenx. It is certainly that turquoise green color too. Thank you jerrys. Jan's sample is spectacular.
