Hunting for New York Devonian Brachiopods


Bguild

Recommended Posts

This past weekend I stopped by Glenerie, NY to look for some Devonian braciopods and gastropods. This was a very cool location as many of the shells, preserved in silica, weather out of the rock complete and ripe for the taking. Thanks @Jeffrey P for suggesting the location! I plan to spend much of this summer exploring the fossil localities of NY and this spot was certainly a great introduction. Here are some of my finds. 

 

Brachiopods

I also found a couple of shells with both valves still intact.

Excellent finds! Jeff sure knows the hot spots!

Wonderful finds! 

Some of those brachiopods are gorgeous! :wub:

Well done!

Nice finds, all around. 

Glenerie is a site I have not visited yet, but wish to get there sometime soon. 

Thanks for the report and pictures.

Very nice!  I am fond of brachiopods, and especially fond of silicified fossils that can be freed from the matrix so you can see all the features.  I have not been to that site, but it's now in my bucket list.

This fellow brought his +1 along with him.

Nice inverts!!! :wub:

Just wondering - could the specimen giving the piggyback ride above be a goniatite ammonoid rather than a gastropod?

I don't believe ammonoids are found at this locality, but I could be wrong.

Congratulations Barret on some excellent finds. Those crevices between the layers must have been pretty rich in fossil material. Specimens with both valves are pretty rare at the site. I only have a handful.

This site is Lower Devonian. I don't think goniatites appeared until the Middle Devonian. I did find one small partially flattened nautiloid there years ago.

This is great! Thanks for the IDs Jeff :1-SlapHands_zpsbb015b76: . I was able to nail down a few of these IDs from looking at your lovely Lower Devonian album, but I was unsure of a few as well. Are all of the examples in the first picture Acrospirifer arreutus? Some, particularly the top two shells appear to have a slightly different morphology.

 

I stumbled across a couple good sized examples of Acrospirifer arreutus preserved with both valves intact, but the one shown above is the only one preserved in Silica that I found. The others are from the harder layers and are a white-ish color.

Acrospirifer arreutus.

Acrospirfer arrectus  seems to be the correct name, but the taxonomy ,well ...

is complicated. :P

Wondering if quotation marks for Acrospirifer are in order? (Hysterolites?)

Your right about the spelling- Acrospirifer arrectus- My other spelling represents a typo. My source of information for the ID is the Devonian Paleontology of New York pg. 155 plate 50, by David M. Linsley. This shows some variation in exterior ornamentation and shape. The illustrations in Linsley's book are from the 13 volumes of Paleontology written and published by James Hall, New York's first state paleontologist, between 1847 and 1894.

Those literary resources you mentioned are insufficient, I think. .

For many of us, it's all that is available. ;)

They are marvelous, love the photo of the back side "hinge" . I didn't start hunting fossils till well after my youngest daughter was out of college...oh, if only  I had  been interested then...she went to school at Bard near Rhinebeck, and I made at least 2 trips a year to that spot. I could have explored, or hunted all over the area I guess...maybe I'll get back there on a future trip to Maine...I often ramble around to avoid big cities and see new country, and find great fossil spots. Bucket list item for me I think.  The ids were helpful to me as well...my book, Index Fossils of North America has pages and pages of brachiapods, but in a book they all look the same, and apparently many of them are differentiated only by their interiors...

Agoniatites vanuxemi?
