First described by Norwood and Preatten in 1855, Shansiella carbonaria is a very common fossil gastropod. The species has been found from 306.95 until 295 million years ago. The genus Shansiella, first described by Yin in 1932, existed from 360.7 until 254 million years ago. The genus described after the
This is an exciting post, as it starts to describe what may become a new species of Mourlonia. The genus Mourlonia has a wide geologic time range, from 466 MYA to recent, marked as 0.012 MYA. Several examples have been defined from Carboniferous, and I am spending time now researching
This specimen is lower crowned than recent ones collected. It is also heavily covered in a white substance that may be mineral aragonite or something else. This being my 11th tooth specimen, I may start reporting on these in groups. The bottom right of the below photo has a piece
This is the largest Solenochilus I have found to date. It was found as part of an interesting array of fossils that included Metacoceras, Petalodus and a Trilobite pygidium all in close proximity. As I was removing the Petalodus, I noticed the shell curve, but it was buried in limestone.
Petalodus ohioensis tooth number 10 is a beautiful specimen. It’s well shaped, well colored and has a solid root. I worked the specimen with an air scribe for some time, removing matrix from a perimeter slowly, before uncovering the tooth itself. Air scribes are useful but troublesome to work with.
The genus Wilkingia was described by Wilson in 1959. The species W. terminale was described by Hoare in 1961. A very common bivalve, I have collected a few dozen specimens of Wilkingia over the past year. I have collected 10 different specimens that were complete as far as length goes.
A quick accidental find tonight. I stack fossil pieces all over the place. This particular piece has been out in the weather all Winter. The tip of a Petalodus Tooth blade attached to the rock. Upon examining the specimen under the microscope, it found it to be removable. With a
One large piece of limestone needed broken into two or three pieces to haul back. With one crack of the 16lb sledge hammer, a chunk of limestone separated and exposed this very nice Petalodus tooth. This particular tooth specimen sets a few firsts. It’s the widest tooth I’ve found at
This week I found a third Solenochilus, this one with a still attached lateral spine. Solenochilus has a unique feature in a pair of lateral spines that were assumed to be used to help the creature swim in a stabilized nature. In numerous specimen photos I’ve seen, I have not
Yesterday I discovered first Petalodus tooth that was removable from the matrix. It’s the first time I’ve been able to examine one in three dimensions easily. I was not aware of how flat one side is compared to the other. There is a root, however it became detached when the
