Hello all, I am looking for good reference material to identify fossils I picked up at Rockford, IA. I haven't been able to find a really good publication that covers the majority of what is find-able in Iowa's Devonian deposits and I'm hoping you can point me in the right direction. Thanks!

New dig area, larger more complete trilobite, assuming Eldredgeops ?
Rocky Stoner posted a topic in Fossil ID
Hey folks, I'm exited ! #30 IS IN ! The first chunk of shale from the new dig at the outcrop mentioned earlier yielded this specimen. It is much, MUCH larger than all the others and looks as if it would have been complete if it hadn't broke out at the edge of the chunk. This shale is very unstable with fractures all over and throughout. It may fall apart at any moment so I photo'd it before doing anything else. I assume it is an Eldredgeops? I think it would be well over 2" long if all of it was there. I never expected to see one this size, how large do they get ? I may try to stabilize it with watered down elmers, or what would you suggest ? Thanks folks, 30 might be my lucky number now. More pics after I "dig in". Kindest regards.

I am aware that many of the weird lumps and bumps of the iron heavy rock formations in Big Brook make some things that look like fossils that arent. Probably the bulk of these are such. However, im very new at this and I would like to know if any of my guesses are correct. I would be grateful if anyone would help me ID these. ( keep in mind that these are from several trips to Big Brook and this is the entire groups' ( 5 ppl 2x) fossils. We are law abiding and only took the limit each visit, we'd like there to be fossils for people to find for a long time there) fossil one: because of the shiny black on it and its weird shape, i thought it may be a fish tooth? like a drumfish. but it looks wrong. fossil two: really degraded squid guard? fossil 3: probably nothing. i thought it was something because of the uniform breakage in the back fossil 4: i thought this was nothing until i cleaned it off and saw the greyish stuff under the clay fossil 5: again i thought it might look like a drumfish tooth but then i bought it home and looked at the computer images and im pretty sure its not a thing. fossil 6: is that a tooth? fossil 7: is this just a clump of rock and mud? fossil 8: I saw mentioned somewhere on the forum a similar find and someone said it might be like shrimp poop? is it? fossil 9: piece of squid guard? fossil 10: idk what it is. it looks like burrows. but not. fossil 11: a tooth, for sure but not sure what? fossil 12: nada or the tiniest squid guard eva ( included bc its a six yr olds find) thank you in advance for any help you choose to lend me.

Hi folks, found a new one this AM. There is a small piece of a cast loosely fitted in the first pic, then removed and flipped for the second. Can you tell what this is ? Its about 1" wide. Thanks. Also, looks like another little trilobite, bit, butt, pygidium ?

Hi folks, I posted this calyx for ID some time ago: http://www.thefossilforum.com/index.php?/topic/75522-not-a-clue-here-please-take-a-look/&page=2 Since then, I decided to do a little prep on it to maybe expose more of it. Sadly, I did not get very far before it "grew" into the matrix ..... dang it ! But it does look a bit better, amazing to me. Thanks again to all.

The missus had an errand to run and asked if I'd like to be dropped off at Arkona for a few hours. Of course, I never turn down an opportunity to get out and collect! It started drizzling, and then pouring. I was still adamant on going, and glad I did. Planning around the weather this year in SW Ontario seems an exercise in futility, as it has been a largely wet and unpredictable season as opposed to more even keel prior years. One of the slim advantages of going to Arkona in the rain is that you can actually see things much better when the ground is wet. As I was going in to the south pit, some intrepid fossil collectors were on their way out, soaked to the skin. They had had enough. They probably thought me foolish for thinking of going down there. And it was indeed mucky. At one point, with the accumulated sticky Arkona clay under my boots, I briefly experienced what life would be like four inches taller. The rains varied in intensity, from a mild drizzle to a somewhat frustrating downpour. Undaunted, I was going to make the most of my two precious hours even as I felt a whole lot heavier being soaked through, runnels and rivulets of rain running roughshod over my ragged mien - lol. I was not gunning for my usual fare this day given the short amount of time and the weather conditions, so it was more about casual surface collecting in the south pit. And so poking through the Arkona clay, I figured I'd beef up my goniatite collection. Here is a row of them in ascending order of size. I am actually quite surprised and proud to have found a fairly large one in this formation, as those generally are nested in the matrix of the Widder Fm above:

Hi everyone! I recently took a middle/high school group to Beltzville State Park to collect fossils from the Devonian Mahantango Fm. We found the usual plethora of crinoids, bryozoa, trilobites and corals, etc. Upon looking under the microscope, one student found a large amount of these tiny (like 3mm across) star-like creatures in one rock - superimposed upon bivalves and coral. She'd love to know what they are for her assignment. Thanks!

Hey folks, just picked this up after lunch. This is the first I've seen anything like this in the garden shale. Does it look like the wings from a trilobite ? It is shown exactly as it split. Is there a way to prepare this ? Thanks !
-
Does anyone recognize this ? I thought it might be a partial print of a cephalon with suture lines but don't see anything resembling this shape or pattern in any of the eldredgeops pics or illustrations I've seen. The opposing "Y"s appear to be symmetrical. Thanks.

This is a cobbled together report of a couple of short excursions in July. Early in the month I took the kids to visit my mother at the old home in northern Pennsylvania. It was a nice escape from the heat and fun to introduce the kids to some of the areas I explored when I was their age. We spent a lot of time playing in the creek. Fresh, living biology was our main interest, but my daughter picked up a couple of nice fossils on the side. She secured a lovely plate, naturally oval shaped, less than 1 cm thick, full of cross-sectional crinoid segment impressions. She also found a nice plate of brachiopod casts. This area is Mississippian or Devonian. These are common fossils for the area, but it's pleasing to consider that these animals were fossilized for millions of years before the fauna we "normally" hunt evolved. Last weekend I got away for a few hours to hunt a local South Carolina waterway for Oligocene and newer material. The water level was ideal and the water was fairly clear, but the overcast conditions made for a bit less than ideal visibility. With the 90+ F air temperatures, being in the 80+ F water with mask and snorkel felt marvelous. I turned up a fair number of teeth of the typical broken-tipped and fragmented variety, mostly C. angustidens (I think) with a single very worn C. megalodon. There were a small handful of fairly nice smaller teeth mixed in. I picked up a couple of nice turtle plastron fragments with good surface detail. I also found an alligator osteoderm which I think is actually a modern piece. Sorry about the dark fossil photos--I never seem to have time to get good photos in daylight, but I'm going to work on it. G

Hi folks, just back from vacation. Realizing more what to look for, I found 5 more pygidia today as well as this little beauty which was in a piece of shale beside the road at the end of my driveway. I picked it up on my way back from the mailbox as it looked promising. This is trilobite (bit) #15 and replaces #7 as my new favorite. I really dig those eyes ! Just one eye was exposed and there was plenty of matrix there to contain the entire trilobite, but sadly after taking great care (and time) to scratch down to the body, there was only a cephalon. I was so hoping this was a complete one. Will keep looking, and hoping. Thanks for looking, Cheers.

Would like fossil ID of the bryozoan, please

Found a nice little spot nearby, I only spent a couple hours and if it's not too hot I'll be heading back tomorrow!

Help planning large fossil trip in Pennsylvania
Fossil123 posted a topic in General Fossil Discussion
(Note: this was originally posted under fossil trips) Hey there! I'm sorry its been so long since I've posted on here but suffice it to say I need your help. I'm planning a six to seven day fossil hunting trip in Pennsylvania (sometime in mid august) and I need your help verifying that the sites I've picked to visit from Robert Beards guide Rock Hounding Pennsylvania are still accessible to collecting as well as coverable given my time frame. The places I'm looking at hunting are sites 27. Beltzville State Park (Outcrops on shoreline), 28. Lehighton, Lehigh Canal (Former borrow pit and outcrop),30. Deer Lake (Borrow Pit), 33. Suedberg (Outcrop in former borrow pit), 35. Centralia (Former strip mine outcrop), 38. Rockville (Former quarry), 48. Walker Lake (Hillside and unpaved road), 51. PPL Montour Preserve (Hillside, Former borrow pit), 57. Uniontown (Former quarry). Any insights as to whether or not theses sites are still accessible to collecting, weather our not you believe covering all these sites within 6 to 7 days is possible, and any other tips and tidbits of information on the sites, and or planning a large trip like this etc, would be greatly appreciated! When I go I'm planning to take notes and pictures and then, when i get back, write a few essays illustrated with pics that I will post on here! Thank you in advance, and thank you to Fossil-Hound for directing me on were to properly post this! Glenn aka Fossil123 -
This is #8 and #9. Both were in the same split of shale. The larger one was barely visible, just 1/2 of the fwd center ridge. Took quite a bit of digging to expose it. I was pretty sure what it was, getting used to the little clues. Thanks again !

Meeting Up With Fossildude19 in Buffalo- July 4th weekend
Jeffrey P posted a topic in Fossil Hunting Trips
I was barely recovered from the Brechin, Ontario trip the weekend before when I headed out to the Buffalo area, an annual pilgrimage July 4th weekend for the past four years. Usually the highlight of the weekend is the planned meet up with Tim (Fossildude19) to do a bit of fossil collecting together. Others often join us, but this year it was just the two of us. Weather was perfect and we hit our favorite spot; Smokes Creek, a Windom Shale, Moscow Formation, Middle Devonian Hamilton Group site. This is Tim doing what he enjoys most- breaking rocks:

Beginning to recognize more of the minor details. A small portion of the eye was protruding from the surface a fresh split. A bit of scratching under the microscope revealed my favorite so far. I call it #7. OK, ...... I'm hooked ! Thanks again folks.

Palaeozygopleura hamiltoniae (gastropod partially encrusted with a bryozoan) Middle Devonian Moscow Formation Windom Shale Hamilton Group Deep Springs Road quarry Lebanon, NY. Usually these are completely enveloped by the bryozoan. First time I've seen one only partly encrusted. -
Found #6 last night. Only a small portion was exposed, I scratched the matrix away to expose the rest. I wish I had learned earlier what to look for more specifically. I am certain that I have overlooked more of what I am looking for than what I have found. Thanks again to all for you guidance, experience and willingness to contribute. Kindest regards.

Upon seeing the very nice recent posts by WhodamanHD, I was prompted to revisit my rock-pile stash and crack a few. Does this look like a trilobite ? If it is, the eye is a bit different than WhodamanHD's find. This one would be a bit larger than the others found here too .... if it actually is one. Thanks for looking. ...more.

I'm still splitting some of the West Virginia mahantango rocks @Rocky Stonergave to me, and I found these too things. One broke as it fell out, so I'm hoping very hard it's not a trilo that I broke the next one also has horizontal lines on it, and a ridge in the middle, which reminds me of a pygidium. I'm not gonna get my hopes up though, what do y'all think?

Hi friends. This is strange for me to understand. I went 3 mi. eastward to the nearest Oriskany Sandstone formation and picked up a modest 40 lb chunk, brought it home and busted it in two. It was relatively hard, coarse grained but inside, there is a cavity, well not really an open cavity but the center is very soft, almost loose sand with what looks like real shells mixed in. They are whitish and very fragile, just like you'd see at the beach. I can easily pick/rake the loose sand out with a needle point and completely expose each piece of shell. (only did 2 so far). Could the sandstone have deteriorated and broken down from the inside out ? Or what ? ? ? Only 2 picks for now, more later if needed. Thanks for an explanation for this one. Kind regards.

Pleurodictyum styloporum and Rugos coral - verify please
Rocky Stoner posted a topic in General Fossil Discussion
New finds in the "extended" berry patch. This is the best example I have so far of the Pleurodictyum styloporum coral. Comparing with this link: http://viewsofthemahantango.blogspot.com/2010/05/i-thought-id-start-my-blog-with-post-on.html and previous post id's. These were right at the surface under 3" of topsoil. The link does not list the rugos coral, which I've seen illustrated elsewhere. Please help verify that what I have here is the rugos. Thanks again. .......more.....
