While sorting through the endless piles of fossil pieces I have set near the lab microscope, I found another piece of a Petalodus Tooth. This is the most incomplete of the teeth I’ve found to date, with only a microscopic tooth chip left behind. However, this helps with microscopic viewsRead More →
My first Petalodus ohioensis Shark Tooth of 2020 is my fifth overall. This specimen is the first with a three dimensional root. I keep a ready supply of limestone boulders near the lab in which I can search through the matrix. This boulder perhaps came from the same general areaRead More →
I’m not certain on the genus and species. I’ve considered Meekopinna Americana and Aviculopinna peracuta as possibilities. However, upon reading an article from the Journal of Paleontology, the entire family is in need of some clarification. We understand, however, that the Paleozoic Pinnidae are in need of a complete re-investigation;Read More →
The genus Odontopteris is one of many seed fern varieties that existed during the Carboniferous. I have high confidence that I have the genus correct, yet, I am awaiting more research before I can confirm. The visible leaf of the glued specimen is 100mm in length.Read More →
When I found my 4th Petalodus Tooth, I thought it was the 3rd. However it turns out that I did indeed find another one that I did not document. This one appears to be half a tooth. It sits on a large piece of limestone, that I may eventually cutRead More →
A fourth Petalodus Tooth has been found in the same general area I found the first three teeth. This tooth looks deep, like the 2nd tooth. The two sides are missing and fractured, likely from splitting the rock. The tooth was dark in color when I found it and turnedRead More →
February 2020 – I have updated this post. I received a more solid identification of Brachycycloceras after a visit to the Carnegie Museum. June 2020 – I am again updating this post. I shared the photo of CM 29726 with Royal Mapes, who said that the specimen is defiantly notRead More →
First described in 1870 by Meek and Worthen, Solenochilus is a genus of Cephalopod. The identification is most likely, as two experts have noted the wide square shape of the specimen. For a short time I considered Ephippioceras. However, this specimen is much too large to be Ephippioceras, which areRead More →
I often find bits of Metacoceras, a Coiled Cephalopod that existed between 314 million years ago until just before the Permian / Triassic Extinction event. I have been looking for complete specimens, but typically they are bisected on some sort of sediment plane within the limestone. Discovery In my localRead More →
I went back to where I found the first Petalodus tooth, and the first rock I split open held another Pennsylvanian Petalodus tooth. This specimen is longer than the first one. It measures 1.5mm more narrow, however this is due to a chipped left corner. The limestone is a bitRead More →
