I have found a piece of petrified wood that I have ID'd as Paraphyllanthoxylon, thought to be a large common tree during the tropical Cretaceous. Very near it, I found a piece of petrified wood that is from the genus Quercus, very modern looking. the two shouldn't be found together as I understand their temporal distribution. Does anybody have a time range for when Paraphyllathoxylon is thought to have existed? I can't find an age range in any of the literature I have looked through (far from an exhaustive search).

Some of us fossil collectors believe there is no such thing as a bad day fossil collecting. Well, yesterday at Red Hill, PA it was muddy, rainy and cold. I'll will have to admit it was still a good day fossil collecting. One of my objectives to collecting at this Upper Devonian site is to find fossil plants, namely Archaeopteris. Well it happened big time. A picture of my truck tailgate tells the whole story of my catch of the day. What was found were 3 species of Archaeopteris, fertile and infertile leaves, large plates and small pieces that I liked too much to discard.

This is a topic I've been meaning to create in the I.D. section for some time now. Hopefully it will be an easier way for interested members to access information regarding my paleobotanical materials. I likewise encourage anyone with Cretaceous Tennessee specimens to post in this topic, to create a better understanding of botanical fossils/palaeoecology/palaeoclimatology, ect. from the cretaceous of Tennessee. I intend to add new materials to this topic for years to come,to ensure a way for researchers to view specimens easily, a benifical concept considering my materials are scattered throughout the TFF in numerous posts in such a way as to be impossible to track for most members and guests of the Forum. Of course a section compiled of all my unknowns will beneficial to myself also. Unless specifically listed with the botanical, all material I post will be Campanian or later. These specimens are recovered material from many diverse sites I collect from. Thank you for viewing my materials and helping with identifications...an untrained person like myself certainly needs all the help I can get!

Hey all, I am in need of a little assistance. I am starting a new research project on the fossil record of American Chestnuts and am having trouble finding any information on their early history and evolution. I have found that they started in Louisiana and moved up northward, but I am having trouble finding dates on when exactly. I was also curious if anyone has an idea of where a good site would be to maybe find an American Chestnut tree leaf (or chestnut) fossil? I know some have been found in Oregon and Idaho, but I am looking for somewhere near southeastern Tennessee. I am willing to make a drive, just don't really have the funds (or time) to fly anywhere to search. Thanks for your help!

Hello all, I came across the attached fossils in shales of the Breathitt Group in southeastern Kentucky, USA (Pennsylvanian, Atokan). The associated strata are full of typical foliage, like Alloiopteris, Neuopteris, etc, as well as calamites and pteridosperm stems (like the ones in the photos). The specific fossils that I can't identify are the small, detached, orbicular "leaves" located near the pteridosperm rachis in the first photo (close up of a different one in the second). They're about 1-2cm in width, some have lost their carbon, some have kept it. There's about 11 of these on the slab and counterpart, all nearly identical. I've collected Pennsylvanin foliage for a couple years now, and haven't seen this before. Textbooks, including Taylor and Taylor (2009), didn't seem to include structures like it. I've also asked around a bit - including a professional Kentucky paleobotanist - but to no avail. And that brings me here . . . any ideas? Tom

Scientific Paper
Stocksdale posted a topic in Partners in Paleontology - Member Contributions to Science
I've been completing a "working paper" on some significant new finds that add some new understanding about the "upland" flora of the Lower Pennsylvanian. I'll be sending what I have to some people like Dr. Bill DiMichele and others to get feedback and determine next steps. But I had a few questions that I'd like some help with: 1. What kind of embargo on information about a working paper is typical. Do I run into issues for it to get published if I share the working paper widely? Should I avoid sharing information about it on the Fossil Forum? 2. Does the location need to be fully revealed? If there is desire by the landowners to keep the location undisclosed, what would one do? Could the location be fully described, but have specific coordiates only available upon request? 3. I do understand that the main specimens being researched in the paper must be housed in a public museum. If there are secondary items being described to understand the setting, do they also need to be public? And, if you do a census (relative abundance of different species) of a location, do all items included in that census need to be housed publicly? 4. What is the process typically used to determine relative abundance of different plant species in a location?- 3 replies

This has to be one of the strangest paleobotanicals i've ever laid eyes on. The material has been replaced by siderite or some other iron type stuff=iron wood! It has been looked at by one Paleobotanist and one Geologist,neither had saw something like this before, and i was told there was a possibility it could be a new species of some type! It's still unidentified. The preservation is nothing short of remarkable....this specimen is so incredibly life like, that one would almost expect it to start moving in your hand! All the internal parts can still be viewed, even veins! Strange....you almost expect a heart to start beating in it! was collected in 2013 from a Late Cretaceous Campanian formation. The outside surface has many holes in a regular pattern which lead to internal parts.- 2 comments

On the afternoon of November 22nd 2013, in the middle of the pouring rain, i found this huge Amber specimen in a Late Cretaceous formation. Location unspecified. This is the current unofficial Tennessee state record. It broke the previous Amber state record which was also set by myself barely two months before finding this specimen. It's the size of a hamburger! The first state record was set by the late mr. Bruce Wade and stood for 99 years. I have been told this specimen is in the top 10 largest Amber specimens to ever be found in America.-

On september 20th 2013 i found this huge Amber specimen at an unspecified location, it is also Late Cretaceous. There have been 3 state records for Amber, i hold 2 of them. The first was set by the late mr. Bruce Wade. That record was surpassed by this specimen 99 years later. This specimen almost doubled the previous record. I have been told it is in the top 10 largest Amber specimens that have ever been found in America.-
