Hi, I believe this is a pelecypod. It was found in an early Pennsylvanian formation sandstone hash plate. Specimen is 3" overall.

 

Would anyone have some thoughts to which superfamily, genus, etc., so I can dig a little deeper on my own?

 

Thank you, Kato

Myalina sp. oyster which is common in Texas and Arizona. See my photo of one from Arizona in the lower left:  http://www.thefossilforum.com/index.php?/topic/88466-arizona-pennsylvanian-perigrinations-travels/&tab=comments#comment-962578

My goal is to leave no stone or fossil unturned.

Thanks! From the shape in the pic above it seems like I could use my specimen to practice doing some fossil prep to reveal more of the shell.

Very cool specimen!

(Just fyi, 'pelecypod' is an old term used for bivalve, if you say the latter it's better ;))

 

@DPS Ammonite very interesting, and nice ID! I personally wouldn't have been able to find that so quickly. 

Here is the Myalina specimen (not the same species) I have, from Mazon Creek. A generous gift from @Nimravis

Looking at the two specimens here, there does seem to be a lot of differences between them; I guess Myalina is one of those "wastebasket taxons" where a bunch of species are dumped into (Google Images seems to confirm this too, lots of very different-looking shells).

Okay, I am at the head of the line when admitting I don't know much about anything and writing pelecypod let's you know that what little I learned was a long time ago.  haha.

 

The naming hierarchy would now be this?

 

Bivalve-Species-Genus

Bivalve-Myacina- ???

Hi, I actually happen to have that paper in my folders! I should have thought to consult that.

 

That would have been a much easier location to find one than where I was at. At least I did not have any road noise to contend with. Just scolding desert wrens and the whoosh of raven wings flying overhead.

What do you mean by this? 

According to Don's paper, the binomial latin name for this one would be Myalinella aff. meeki (which is a synonym to Myalina aff. meeki). Bivalve is the name of the class. The full classification of this one would then be, according to the Linnean classification system:

Domain: Eukaryota

Kingdom: Animalia

Phylum: Mollusca

Class: Bivalvia

Subclass: Pteriomorpha

Order: Myalinida

Family: Myalinidae

Genus: Myalinella (or Mialyna)

Species: Myalinella aff. meeki (or Myalina aff. meeki)

Thanks! That's exactly what I was wanting to know. Now I can bookmark studying the Linnean classification system on inclement days.

Well you’re in for a tough time my friend :rofl: Let us know when you can remember all the different gastropod families by heart! ;)

haha...obviously, that will never happen but it may help me to gain an understanding of the overall picture. It does seem I am coming across more and more bivalves as I've started exploring the Pennsylvanian formations.

Studying the full classification is of course a complete waste of time. However, learning the basics (and what is bigger than what, eg ‘order’ is bigger than ‘family’) does help and that is definitely useful. 

 

I look forward to see some of your future trip reports of your finds in the Pennsylvanian, if you’re finding bivalves that’s really great!

I am finding some okay stuff, but I need to classify more specimens before I write up a trip report. Definitely finding okay bivalves, cephalopods, orthocones, etc. Picked these out to bring home on a short, quick exploratory hike this morning.

If you could number the specimens in the photo, it would make it easier to offer suggestions as to the IDs.

Hi, Don. Thanks for the suggestion and offer. Actually this was more of a pic to let Max-fossils know I've been finding a lot of variety in the lower Pennsylvanian...the subject formation of an upcoming field trip report. I think I might actually now be able to adequately name the above enough to not look too ignorant.

 

Thanks! Kato

The New Mexico Pennsylvanian is certainly a lot of fun to poke around in.

 

Don

Yeah, I've been overwhelmed by the variety in the lower Pennsylvanian. Nothing world class but just a nice variety and plenty to keep a person entertained. I have yet to explore the middle and upper Pennsylvanian formations.

Wow nice! I love that red brachiopod, looks really special!

I hate to make only best guesses, but maybe this will help a little.

And of course, subject to correction.
