   You certainly move some earth!   Some interesting stuff and I sure hope you find that complete and perfect phyllocarid someday.   Good luck my friend.

I'm jealous, Al, though looking at your sledge hammer is making my back hurt even more than it has been this week. It looks like you may be on to something with those phylocarids. Thanks for showing your finds. I'm pretty sure I've found eldredgeops at DSR, but I can't say where, exactly. ("You can't say, or you CAN'T say?" "I can't say.")

Ok here’s part 3! Sorry doing my post in between house work ha. 
 

Sometimes I like to wander.......it’s a chance for me to rest from digging (I’m usually a digger vs picker at DSR). Ive been wondering if there are some hidden treasures in the upper quarry. No one really digs there and as a result there isn’t much for fresh shelfs or slabs to move. I saw a spot with a few pieces of shale sticking out and took a look.  
 

Behold in all its glory!!!

The absolute least appealing exposure in the quarry!! :heartylaugh:.....the layer I found is half way up in this picture roughly where the “hole” in the outcrop is in the picture. 

 

 

it was a layer of “hash” debris.....and there was an Eldredgeops fragment on almost every piece I grabbed. I also found some Eldredgeops fragments slightly above and below the hash bedding plane so it could be in the whole interval itself but I need to explore more to know. Considering I barely got into it and maybe got my hands less that a square foot of the bedding plane I think I found a high density of Eldredgeops.

The bottom piece is I what the “hash” bedding plane was like. I found 6 cephalons and as many pygidiums.

This was the first piece I pulled out....saw the pygidium and glabella imprint and I kinda had a “Whaaaaaaaat?” Moment.

This Eldredgeops cephalon looks like it’s straight outta Briggs rd but it’s DSR!! Check out the eye detail!!! :) Not from the hash layer.

Another nice cephalon. Not from the hash layer.
 

I’m having formatting issues so I’m going to finish up in a very short part 4....

here is one last shot of a hash plate with 2 pygidiums and there is actually a cephalon disguised in that mess too lol. 



Other notable finds:

I always keep the “grammys” when I see them lol. Grammysoidea

I really liked this complete cephalopod and it looks real nice all cut on a plate like that. 
 

I was able to bring home larger slabs now that I have a table tile saw at home. I used it to cut my phyllocarid down as well. So useful!!!! 

 

To conclude:

 

-maybe found a layer with predictable phyllocarids?

-possibly found a layer for predictable Eldredgeops?

 

That is why I called it...a “fascinating” day :) 

 

Anyway....that’s it everyone. Thanks for reading! Hope you enjoyed this thought provoking post!

Thanks!! I have only found 1 Eldredgeops cephalon ever anywhere else in the quarry so I was floored to come across a half dozen in 1 single spot!!!! Removing overburden was the backache omg!!!!

Nice finds... I like everything from these sites, including the bivalves. The orthocone does look really nice on a trimmed plate - a saw is a necessity for some locations' material.

I am glad to see you having such successful hunts at DSR!  Good stuff!

Really nice finds, Al, especially the phyllocarid, rhinocarid, and greenops.  Congratulations. All of this highlights why DSR is such a rewarding and interesting site. Eldredgeops, by the way, are not rare at DSR, just less common than Greenops and Dipleura. When I first started collecting at DSR I was collecting at the highest level of the quarry and Eldredegops was fairly abundant up there. Sadly, those exposures have been dug away now. Certainly I played a part in that. However, an enterprising individual could, with some extra digging possibly open up some new possibilities in that section of the quarry, hint, hint.

Indeed!

You are obviously applying the right mix of exploring (I would like to call it "micro-prospecting") and digging at this site. And that really pays off!

This would be one of the most appealing exposures around me!! :D

Wow Jeff!! Never realized that. See you have much more experience than me :).....I noticed the Eldredgeops are not common at all in the lower parts of the quarry where Greenops and dipleura show up. In those layers I can’t find Eldredgeops to save my life.....I’ve only found 1 cephalon in the lower quarry compared to dozens of greenops partials (and 5-6 complete) and dipleura partials. It would be cool to have a spot to get some consistent Eldredgeops! Since Briggs rd is now out of commission it would be cool to have another spot. I’ll have to try and open it up so we can all enjoy :)

Thanks @Wrangellian @Darktooth 

 

@FranzBernhard seeing what you deal with really makes me appreciate my collecting areas.

Well done, Al.

Sometimes we bump into concentrations of a species either by layer or by lateral spread (for example, a bedding plane that may have been a depression on the sea floor where stuff gets swept in). Many trilobites were gregarious, and so finding a number of them together is -- beyond being a real treat to find -- suggested to represent behaviour (such as moulting or mating in groups as there is safety in numbers!). Also, the relative abundance of certain species can speak to the particular environment that may have been more or less hospitable to them, and available favourite foods. :P

Thanks Kane! I wondered the same...I was considering trying to get a nice bedding plane open in the future and try to see what the differences would be in the rock and fauna. Maybe I only found an isolated patch...or maybe they are more commonly found in Those intervals....I didn’t dig enough to know. According to the literature it is said there are 3 cycles of shallowing and deepening at DSR. Not sure which trilobite is associated with which environment....would be fun to try and do some research on it. Thanks for the extra insight Kane :)

Your enthusiasm and excitement over your finds is infectious as always Al! While reading your reports I get excited myself and feel that I was right there with you. Maybe one day I will be... ;) :) 

 

Here’s hoping your Eldredgeops layer produces many wonderful specimens! :fingerscrossed:

Thanks for the guided tour of your exploring efforts Al. Makes me wish I had gotten moving a little earlier in the day and headed north instead of staying local hunting Pennsylvanian plants.  I am hopeful of getting back up there one more time before the weather makes it inhospitable (though truth be told the first trip this year was collecting in the snow so maybe I have more time than I think)

Congrats on the intriguing finds.

Cool report. Love the hash plates. Those always interest me. Though complete trilobites are my goal. Hope I can make it back some day.

Congrats on the productive day, Al!  As usual, I'm most enamoured with the orthoconic nautiloid - very nice! :wub:
