gastropod ? ammonite ? goniatite ?

[Rocky Stoner]

Hi again folks.

There are sparsely scattered chunks of sandstone and other rock here. Today I found this one barely exposed at the surface.

It was extremely difficult to break in two and is full of sparkles, like small quartz flakes. It is not the normal sandstone.

There appears to be a section of a crinoid and a spiral gastropod of sorts.

I found no reference to it in the link posted above and have not seen another one here.

Looks like it may be an "open" tapered coil where the coils do not touch one another, not sure though.

Something new here every day .... never a dull moment. (unless I'm boring you with the same ol same ol)

Kind regards.

Here is a pic of the rock and one of the crinoid.

I think it's oriskany sandstone/quartzite. It's sometimes metamorphosed and contains Gastropoda, which I what I believe it is. It's slightly later than mahantango I think.

As best I can tell, I am at the base of a mountain on which these 4 formations all come to the surface.

Being the mountain was likely once the as high as the alps, the variety here is understandable.

 

Thanks.

Neat finds, Rocky.

I think you have an internal cast of a gastropod.

Your crinoid actually looks more like a coral.

Hey, I have access to many needmore exposures ! Thanks for that tidbit.

(UPS left the package on the porch Thur.)

Regards.

Top one is certainly an internal cast of a coiled gastropod, Thats a pretty common fossil in both marine and lacustrine sediments.  If it was say a cephalopod, you would probably be seeing some partitions along the curve, which is not present.  Here is a similar one I found in the mississippian Redwall Limestone.

Thanks Chris, that looks like a match to me.

Kindest regards from Wild Wonderful West Virginia.

This is the first one of these that I've found in the densely populated part of the garden shale.
