will stevenson Posted March 24, 2019 Share Posted March 24, 2019 I recently purchase this from a seller who claimed it was fossil wood from India, have you guys heard of Indian fossil wood and it more looks like some type of palm, maybe calamities, but I’m not really sure thanks for looking note how mineralised it is I don’t know what it is though as it is very heavy Quote Link to post Share on other sites

The map shows some bedrock labeled as upper paleozoic terrestrial. That could include rocks of the right age. 1 Quote Link to post Share on other sites

Kato Posted March 24, 2019 Share Posted March 24, 2019 I should have added some more information. Stigmaria is the name generally given to the various root casts of the Pennsylvanian period regardless of known plant genus. Without knowing about any associated plants found at the same location, it is not likely one can narrow this particular specimen down to a species of Lepidodendron or Sigillaria, etc. Did they provide any information as to where in India it was found? I guess my presumption was that it is from the Carboniferous age (Mississippian-Pennsylvanian). If the seller could provide a name of a town nearby that would help with establishing if the correct time periods would apply. Perhaps you could provide a slightly more focused photo of the 2nd photo to show more detail? It sort of appears there is a plant impression there? 3 Quote Link to post Share on other sites
Kato Posted March 24, 2019 Share Posted March 24, 2019 If you are interested here is a snapshot of a page from an older bit of info on India Indian Fossil Pteridophytes https://books.google.com/books?id=HIIS8bUqSioC&pg=PA10&dq=fossil+lycopods+stigmaria+of+India&hl=en&sa=X&ved=0ahUKEwiHxbOo2JvhAhWsCDQIHeQXAiAQ6AEIKDAA#v=onepage&q=fossil lycopods stigmaria of India&f=false This should keep you busy for awhile... If the article is correct. It appears the only Lycopsid known at the time was Cyclodendron. A lot of time and research into new geographical locations is likely to have changed that information. 2 Quote Link to post Share on other sites
will stevenson Posted March 24, 2019 Author Share Posted March 24, 2019 i can rovide more photos but i bought the fossil from a fair so i cannot contact the seller unfortunately, on a side note it looks almost pyritized? Quote Link to post Share on other sites
Rockwood Posted March 24, 2019 Share Posted March 24, 2019 I think it's a stigmaria from the inside out the way my example is exposed. Pyrite is common with plant fossils. 2 Quote Link to post Share on other sites

No problem. It is certainly possible to be from India. A quick scan online lists many modern research papers indicating the possibility of more types of Lycopods. 1 Quote Link to post Share on other sites

It does google out looking something like this too I see. 1 Quote Link to post Share on other sites
