I was hiking up a ridge between two washes looking at exposed formations for plant and insect fossils in mid-to-upper Pennsylvanian formations. I came across a possible sandstone formation with no evident bed layering. This formation was 1-1.5 meter thick and appears to have plant fragments scattered throughout. Perhaps the fragments are actually the result of this being a high energy deposition area and sedimentation of another type was broken up and preserved in the matrix. Preservation is poor. No evidence of shells of other sea fauna seen in examining the specimens. In the first photo is 'looks like' branching of some type is preserved as seen in the upper middle. The length of that branched object is about 200mm or 8 inches. Branching like this is not something I'd expect for ferns or other plants of the time like cordaites, calamites, etc. Second photo shows larger objects of maximum length 40 centimeters (about 16 inches). The top of the central most piece is what has me thinking this is sedimentation that was broken up and captured in the matrix. There seems to be layering which is not something I'd expect of plants from about 300 million years ago in this area. Again, there seems to be a lot of smaller fragments captured in the rest of the matrix. A 3rd photo showing another object. The lower, larger object suggestive of branching Any ideas of what I might have been seeing? Perhaps some suggestions of what I should try to look for when I cross this formation again? Thanks, Kato.

Hi all, I noticed this weird little object on a rock in my collection from the famous Talbragar Fish Beds (late Jurassic of Australia) and I was wondering whether it might be a feathery insect antenna or just a small bit of plant. Both plants (conifers and ferns mostly) and rare insects are known from the site. It measures only 5 mm long and I have done a quick drawing of it to show the form easier. Note the double branching tips on the lower filaments. Cheers!
