I found this near Seneca Lake in NYS...Middle Devonian

I'm not sure, but I think it is the whole piece shown.  There is matrix covering it so, I'm not sure.  The only thing that I've come up with is from Linsely's book and it's title is Bryozoan "stick form.

Thanks

Greg

It does look like a branching form of a bryozoan. I'm not very good with bryozoans but I'm guessing it will be difficult to impossible to identify without the formation. If it is Middle Devonian do you have an idea of the formation?

  • Fossildude19 changed the title to Bryozoan?

Have a look HERE at Atactotoechus fructicosus (Hall)

Looks like an encrusting bryozoan, possibly on a cephalopod.

I believe it is called the Deep Run member.  Other than that I'll have to ask(which I will).  A friend gave me a couple of 5 gal. buckets filled with rocks from several different areas.

I'm guessing a species of Leptotrypella, maybe tuberata which is reported from the Deep Run.

Try Richard S Boardman's report on the Trepostomatous Bryozoa of the Hamilton Group of New York State for more info. It apparently lists L. tuberata as the only one from the member but there are other species within the overlying and underlying members. The report is also old so new information is possible.  https://pubs.usgs.gov/pp/0340/report.pdf

The rock unit is called the Kipp Road Bed, Deep Run Shale Member, Moscow Formation, Hamilton Group

I think it may be something different.

Atactotoechus fruiticosis is what it resembles to me.  Though, I'm usually wrong.

Thanks

It very well could be. Bryozoans are hard and I'll be the first to say I'm inexperienced with them. Atactotoechus seem to be very similar to Leptotrypella species. Remember that overall form varies within a single bryozoan species. It's possible that analysis of zooecia, like sectioned slices, are needed for the identification. The paper I linked includes both Ataceotoechus species and Leptotrypella species from the Hamilton Group and the author included sectioned portions with zooecia for his identifications.

 

It's also clear the Hamilton Group has undergone a lot of stratigraphic revision. This makes it more difficult to nail down the species but perhaps there are more recent papers on bryozoans of the "new" stratigraphic sections, like the Kipp Road Bed. Clues could also be found with analyzing where in the Member the Kipp Road Bed is.

 

From the report I linked earlier.

Tim and Tom...I finally got time to look over the PDF you sent to me.  And I was able to clean the matrix from the entire section.  It has the same marking till the termination point.  Two things come to mind:  The shape of the part I found resembles that of Leptotrypella asterica and also Atactotoechus fruiticosis .  The second thought is.  If you look at the cross section of the Leptotrypella asterica from the paper (plate 9, 1E) and the cross section of  several pieces of Atactotoechus fruiticosis ...I found from the same area (in the photo), you'll also notice a similarity.  Also a related note:  the guy who gave me the rocks/fossils feels it's a Stictopora (which I can't find).

I'm not sure this is going to help.  But, I had forgotten...when the tip of this piece broke off.  The center also broke in half.  It was a dark brown and straight grain.  So, I tried to get it apart...but was unable to(perhaps I could've tried harder, but I didn't want a mess).  I scribed off the end and then buffed it.  The image below is from a digital microscope which is not great at colors.  However the inside is a brown crystalline form.
