Final Episode of Belated DSR Trip: Arthropods, Cephalopods, etc.

[Peat Burns]

Here is the final installment of my trip report to DSR (last spring with TFF group meet).  These are the rest of the specimens including Gastropoda, Cephalopoda, Hyolitha, Phyllocarida, Trilobita, Ectoprocta, Plantae, etc.  Scale in mm.

 

 

A Palaeozygopleura encrusted with the bryozoan Leptotrypella amplectens.

I am not sure what this is.  I am assuming gastropod, but unlike the Bellarophontids, this one doesn't seem to have the ridge or furrow down the center.  It's also quite large.  And the striations look different than any I can find that are typical of the site.  @Jeffrey P, @Fossildude19?

Here are the cephalopods and hyoliths.

 

 

 

 

 

 

Michelinoceras? Dolorthoceras? Spyroceras?

And finally the Arthropods and Plant:

 

 

 

 

What is the series of depressions on the ventral surface (i think my photo is up-side-down...)?  Could those be the impression of disarticulated jaws?

 

 

A different specimen, magnified to show surface features.

 

 

I originally thought this might be a broken bit of cephalopod.  Then I thought maybe the interior side of a Dipleura pygidium.  Now I am wondering if it is not the interior of a Phyllocarid carapace.  It's hard to tell from the photo, but it is concave, with the left side curving sharply upwards and the right side being the deepest.  It has little pustules near the left margin which I'll show magnified in the next photos.

 

 

 

I originally thought this was a bivalve hinge.  But now I am wondering if this might be a phyllocarid telson.  I tried prepping down the sides to see if it was a clam, but it does not continue into the rock.

 

 

And last but not least, a seedless vascular plant:

 

Thanks for looking!  Briggs Rd. belated report will be coming soon.

Oh my gosh, Tony - I am speechless!!!  I LOVE all of these fossils!!!  What a wonderful array of specimens from one site!!!

Great stuff. I don't recall if you mentioned how long did you spend at that site? In any case you sure brought home a large and varied haul!

Same as Monica, I'm

Tony, 

I think it is an imprint of a Paleozygopleura gastropod.

 That makes so much more sense.  Why didn't I think of that?   Thank you, Tim.

Thanks, Monica! .  It was definitely a bucket lister after seeing all the reports from @Darktooth, Tim, Kane, Jeffrey P, and others.  A truly unique and diverse site.

Thanks Wrangellian.  I think I was there about 4 hours (?).  We started at Briggs Rd. and spent two hours or so there and then moved on to DSR.  I think I drove back home right after I finished collecting.  It was worth the 10-hour drive 

 

The people that live close to the site and regularly visit probably sprinkle most of these taxa on their cereal every morning, but being my first time there, I collected and reported pretty much every species I found.

Tony, 

This one may be a different bivalve - Orthonata carinata.

Holy schneikies.  I'd am much happier with that than a even a Phyllocarid bit.  That would push my bivalve species list up even further.  Thanks!

 

Any idea on that large aff. gastropoda with the fine raised striae?

Maybe Mourlonia lucina, or Mourlonia rugulata ?

Love the detail on that phyllocarid carapace

Ha! Well I wish they'd send some to me instead of that, or filling their kitty litter trays, or...

But I know what you mean!
