  12. Ohio Fossil

    Probably not the best fossil, but contains many species, which I find interesting.
  13. Found this fossil and sent it to a paleoethnobotanist who was able to pull a pollen spore and identify the species.
  14. Found this in North Eastern Ohio also. Pretty nice I think.
  15. Neuropteris?

    I believe these are Neuropteris fern pinnules, but correct me if I'm wrong. USGS map says the location was "Allegheny and Pottsville Formations, Undivided" and that it is Pennsylvanian in age.
  16. Found this in Ohio. I have found several of these, but this is the largest one so far.
  17. Almost there! Over 270 pages of full color fossils from the Pennsylvanian of North Texas The long-awaited sequel to the Pennsylvanian Fossils of North Texas (2003) Available Q4 2015 in hardcopy, digital and e-reader formats.
  18. If you have ever collected fish from the classic vertebrate locality near Linton, Ohio or have obtained fish specimens from there, I would like to share some of what I have learned about the type of fish called paleoniscoids (also spelled palaeoniscoids) that occur there. Paleoniscoid fish have thick, rhomboidal scales made of dentine-type bone with a surface of hard enamel-like material called ganoin and on the external surface of the ganoin there are pits and fine canals. They resemble (body-wise) what most people think of commonly as a “fish-shape” except they have “armor-like” scales. They are set apart from the chondrichthyans (sharks), the dipnoans (lungfish) and the coelacanths, which also occur in the Linton cannel. The Linton paleoniscoids can be divided into two family groups, the elonichthyids (1 species) and the haplolepids (6 species). I’ve attached a pdf file called “1. Identifying Linton Paleoniscoid Fish” which describes the fishes for species identification. I tried to keep the terminology minimal, but to describe the differences some was necessary. To aid in identifying haplolepid species, I have put together an illustration called “Linton Haplolepids”. The accompanying jpegs show the illustration and most of the different paleoniscoid types. Because I no longer have any specimens (see pdf file: “2. My Linton Collection and Recollections”), I cannot provide photos of two of the species. I hope this information will be useful and bring about more interest in learning about and collecting in coal measure deposits wherever they occur. 1a Identifying Linton Paleoniscoid Fish.pdf 2 My Linton Collection and Recollections.pdf
