Dang, man...you really know how to write up a report! It was a pleasure.

Here's some of fossils I found that Sunday at Deep Springs Road:

a bivalve, Paleoneilo emerginata

[Jeffrey P]

Another bivalve:

Actinopteria boydi

[Jeffrey P]

And a bryozoan:

Taeniopora exigua

And another bivalve:

Cypricardella tenuistrata

And another Cypricardella:

and a rugose coral:

These are actually fairly uncommon there.

One more bivalve:

Modiomorpha concentrica

That's it. Hope you enjoy.

Interesting lot of bivalves... usually we see little to none in Paleozoic rocks, in favor of brachs.

[Jeffrey P]

I think it's worth noting that Middle Devonian Hamilton Group sites in Central New York like Deep Springs Road manifest a large bivalve population and tremendous variety. There were plenty of brachs too. These days I tend to leave those unless it's an incredibly good specimen or a species new for my collection. Incidentally, I was at an Ordovician site outside Montreal yesterday which also had a large bivalve population, in some beds they outnumbered the brachiopods and I think they at least matched them in terms of number of species.

Jeff,

Thanks for adding your finds.

No goniatites this time around?

Hi Tim,

Yeah. Sorry. No ammonites on that day I thought worth keeping. Thanks for posting the species list for Deep Springs Road, though I have collected at least ten species of brachs and bivalves there that are not on that list. Still a good reference for most of the common species you'll likely find. It's not unusual to find at least a dozen species in one rock you can pick up in your hand. Now that's what I call diversity.

Eric,

Central New York is pretty amazing in terms of faunal variety.

Here is the faunal list from Deep Springs Road:

...

You're not kidding! There are more bivalves than brachs in that list (by one).

That would be akin to me finding 12 different types of brach in my Upper Cret.! (or maybe not, I don't know if the two are that comparable - maybe more like 5 types of brach?)

[traveltip1]

nice report.

[Fossildude19]

nice report.

Thanks!

Tim, another great report! Hopefully we can do a joint trip soon. That is so cool you guys worked with the teenager. I feel like this is great gateway stuff into science. He may just listen a little harder now when he goes back to school.

I truly enjoyed that wonderfully trip report. Makes me wish I had the knack for describing events in such an interesting manner. Looks like you left quite a range of finds.

Thanks Paul.

Hope to get out sometime later this fall with you.

Thank you for the compliment. I truly appreciate people reading my reports, and so much the better if they actually enjoy them.

I forgot to post this one very exquisite brachiopod specimen I found that day; Elita fimbriata.

[Wrangellian]

OK, so an equal number of each?

[Jeffrey P]

I would say that brachiopods are definitely more plentiful at the site, but that a wide variety of bivalves are plentiful too.

[Pagurus]

I'm already looking forward to our next get-together. I've finally gotten around to taking a few photos of my finds that day. I didn't find that giant Dipleura I wanted or any other complete trilobites for that matter, but I did end the day with lots of small hash plates I can give away to kids and a few decent bivalves and brachs, along with a few small partial Eldredgeops and Greenops. I'm not very good with ID's but I'll do my best and I'll be glad to hear any and all corrections.

Bivalves

Leiopteria conradi ?

Paleoneilo filosa ?

Paleoneilo filosa ?

Grammysioidea arcuata , I think

Modiomorpha mytiloides? concentrica?

Brachiopods

Rhipidomella sp.

Rhipidomella sp.

Mucrospirifer

Mediospirifer audaculus ?

It was a good day!

[Fossildude19]

Nice finds, Mike!

Good variety.

Thanks for posting them here.

Nice bivalves and brachs Mike. A fine testament to the biodiversity of this site. Again, great collecting with you. Thanks for sharing.
