Howdy folks! I am currently working on a project discussing the now closed Swatara gap site. It was an amazing locality with intriguing history, and I’m hoping to do it justice in my presentation. In the pursuit of this goal, I’d like to include a few shots of what this site looked like before it was backfilled with limestone, however my initial source for these photos unfortunately lost them. If anyone has Shots of the old site, I’d appreciate it if you could share them, and full credit will be given in the presentation. Appreciate your time guys, happy digging!

This is a question about best practices for highlighting fossils in place in public parks without risking vandalism (by which I mean someone removing the fossils for their own private use). This question has arisen in the context of several complete trilobites that have now been found on blocks of limestone used as landscaping in a chicago public park (pics below). Has anyone seen or taken part in an effort to highlight fossils in place in a public city park in a way that deters vandalism rather than invites it? Deterrents might include framed enclosures around the fossils, or maybe even a clear epoxy block poured directly onto the fossil? I don’t think “honor system” methods used in national parks would work in this urban cultural context, and a building to enclose the whole site would be overkill and would run counter to the purpose of the site’s outdoor green space. All feedback welcome, including names of folks who might have better answers than we ourselves can think of

Dave's Down To Earth Rock Shop and Prehistoric Life Museum
Nimravis posted a topic in A Trip to the Museum
Today I took a quick ride to the small suburb of Evanston, right out side of Chicago. This is the home of Dave's Down To Earth Rock Shop and Prehistoric Life Museum. If memory serves me correct, Dave's has been in Evanston for the past 40+ years and it is a family owned business. Dave's recently moved to it's new home on Main Street and if you every get a chance to be in the Chicago area, this is a must see- you will definitely not be disappointed. From the outside, you would not believe that this store has a museum that houses such a great variety of fossil life and the most extensive collection / variety of Mazon Creek fauna that I have ever seen, including 3 Holotype Mazon Creek fossils named after Dave and his parents who found them. Here are some overview pictures of the Museum. Here are some overview of the various displays.

Got out early and drove to check a spot out. Found a broken isotelus that is preserved amazing. Couldn't find the other part. Maybe next time. Will add photos when I get home.

Looking for Nileus trilobites for Trade
Newbie_1971 posted a topic in Member-to-Member Fossil Trades
Any nileus trilobites for trade? -
Hooked back up with Kaden again today and found a couple more Flexis. Also found a couple things I have yet to ID. I know that he found at least one full roller. Not a great day, but not horrible either. We checked a couple spots out, and even found a new spot with a lot of potential. We didn't spend a bunch of time fossil hunting as we also went fishing. We have plans on going out of state to chase trilobites next weekend! The large Flexi I found looked as if he was upset setting on his perch. Any ideas on the Fossil in the bottom two photos? Approximately 3/4" wide and 1/2" tall.

Friday I was able to take advantage of having the day off from work with no Honey-do list to bog me down. What is a Man to do? Go on a fossilhunt of course! It had been awhile since my last hunt in New Jersey so I was due. I almost didn't go as I wasn't feeling the best, but I decided not to let that ruin the day. I spent about 5 hours digging in 30° weather. It did snow for about the last hour or 2, but it didn't bother me. I moved alot of rock and was rewarded with some Goodies. My favorite finds were some Greenops trilobites. Also found some nice brachiopods and bivalves. There is some plant material found at the site. So far I had only found single isolated branches but this time I found a piece with multiple branches. I hope you will enjoy!

On a trip to southern Indiana yesterday I met a member of the fourm, Newbie_1971, and he helped me find my first trilobite! I found several well preserved gastropods as well as some pieces of isotelus trilobites.

I am going to start a thread and just add to it as the days go on. Instead of posting alot of threads for each hunt. If that is ok. Jumped out after work today and within 5 minutes I found a slightly damaged whole Flexicalymene. I slowed down a bit today and believe I found another cheek plate, this time loose. I also am adding photos of other finds today, along with a shot of that small trilobite I found the other day, and a new purchased trilobite that was delivered today.

Ordered these from Canada the other day. I bought a pair of flexis, an isotelus roller, and an isotelus in matrix ... got them this afternoon. Pretty happy with them.

I have a nice little slab of Platteville Formation (Mifflin Member) from the Ordovician of SW Wisconsin that I received from @connorp late last year. I am working on a post that describes all of the great things in it, but want to get a couple of ID's cleared up so I can be more concise in that post. Here are three trilobite pieces found on the slab that I have taken a stab at an ID, but would love confirmation/correction. Hopefully there is enough there for some of our trilobite experts such as @piranha , @Kane or any others to offer some advice. Thanks for any insights anyone can offer. Each picture is numbered in the upper left. Mike Here is a picture of the small slab with the location of the trilobites in question numbered. The sharp eyed will see another trilobite cephalon in the lower portion of the slab. I am fairly certain that one is Gabriceraurus mifflinensis. Here is the first question. This looks like the best match I can find for species listed from that formation, but I'm not certain. I wish I could get this one a bit cleaner, but the matrix left is pretty hard and stuck to the pygidium. This one may be a stretch as there is not much there, but maybe enough to be recognizable (or maybe not). Thanks for any help.

So, I will admit, I am severely uneducated when it comes to trilobites, but I’d love to learn more about them — the different species, what’s rare, what’s common, formations they’re found in, etc. I don’t have any in my collection yet, and I’d like to change that. Any recommendations where I could start my learning? Books, articles, papers, anything is appreciated.

I have found a spot in eastern Indiana that has TONS of trilobits. I have been several times to this spot to find complete specimens but have come up empty handed. So I decided to read through the forum and I found some information about looking for spots that were deep sea locations instead of shallower/Beach spots. Are there any indications that you can look for to tell you that you are in a "deeper sea" location as opposed to a beach/ shallow sea location?

Fellow members, I have been offered this Dicranurus. At first glance it appears to be well prepped etc. with no signs of obvious fractures etc. As one should be on guard when purchasing Moroccan material, I would like to seek counsel / opinions / another pair of eyes regarding this specimen which I have been offered. Can anyone see any signs of repair and / or restoration? Thankyou in advance, much appreciated. 7382B30E-FC78-42BF-AD84-380811D50D9E.mov

Hopped out after work today and found a Hotspot. Found 3 fairly good trilobites, another whole, but damaged I believe. Still haven't cleaned it. Will post more photos in a bit. I am super stoked! Thanks again guys!

Greetings. On 8/6/23 I was out around Pioche, Nevada looking for trilobites. I found a number of specimens and decided on a whim to bring some larger sections of trilobite-bearing shale home for context purposes. After sorting the smaller trilobite samples I sat down to inspect the larger shale pieces. There was one item that I could not identify and I wonder if it might be part of an anomalocaris grasping appendage. Below are two pictures, one is a close-up and one that is a larger shot containing a trilobite cephalon for comparative purposes. The spine at the end of the (maybe anomalocaris) lobe is not as long as most I’ve seen in pictures but I did find one from China that resembled the one in the picture rather closely. Would any of you kindly venture an opinion as to what I may have found? Thanks in advance.

Hello to all: Joined in 2020 but only have become active now. Have been collecting fossils---passion is trilobites--for 40 years around the US and in eastern Canada. Have embarked recently on learning the art and science of fossil preparation. Leaving on a collecting trip Sept 22nd: will visit Penn-Dixie, Spring Creek near Alden, Rickard Hill Rd near Schoharie, and may be able to visit sites around Madison County and Sarasota Springs. Should be on the road for about two weeks and if things work out, may be able to do some work along the Canadian side of Lake Ontario. If folks have any other recommendation regarding collecting in western and northern NY, suggestions would be welcome and appreciated. I have attached a couple of images: Paradoxides davidas collected in Newfoundland, and Odontopleura calllicera collected in West Virginia. I should also note that identification has not been my strong suit so if folks find the ID of either doubtful please let me know. Regards, Sandy (a guy).

First time fossil buyer - was I duped at the Denver show?
thegnome54 posted a topic in General Fossil Discussion
Hello all, I've been a fossil admirer for many years and finally pulled the trigger to get a few pieces of my own this week at the Denver show. Regrettably, I didn't do any research into fakes beforehand - didn't even cross my mind, as this is an organized and seemingly reputable event. I bought two trilobite fossils and one brittle star. Each was from a different vendor, all of whom were from Morocco. When I started doing some reading to try to confirm their species after I got home, I found many resources about fake fossils including this forum. I now suspect that all three of my fossils are fakes, as I can see what appear to be pinholes from resin bubbles on them. I've attached some photos. The larger trilobite I got from a guy who had tons of different-sized trilobites in various positions on different bits of stone, and it has visible cracks where it's been reassembled. However it seems to have clear pinholes across its head. The brittle star seems like the most obvious fake after learning more about fakes, given the color and shininess plus the couple of pinholes. I'm not really sure what to do at this point - I still admire these pieces and find them quite beautiful. If they're casts of real fossils they retain some of their interest for me. But it feels really bad to have been duped, potentially three times, in my first foray into fossil collecting. I have half a mind to go back and confront the vendors (I paid two of them with zelle and have their names and information) but I'm not sure what would be gained. Is there some way I could notify the venue so that other buyers don't get swindled? Curious to hear people's thoughts on whether these are indeed all fakes, and what you would do in my place. Currently I'm leaning towards considering it a lesson and keeping them as pieces of art, but the bad taste does linger. Thanks for your time!

Hello Everyone, It feels like Deja Vu .. but it is that time of year again .. again. Wait, have I posted this already. A photo dump, of the few photos I snapped, of some of my more interesting finds. The Crowne Plaza had some enourmous mineral specimens and some fantastic fossils on offer this year. Though most were way outside of my budget. But photos are FREE ! The cutest fake fossil ? Yes ... and I almost bought one. I kick myself still for not pulling the trigger. Selfies with minerals anyone ?? .. yes please. Children for scale. I like it and I'm sticking with it, because I'm a rebel. Who needs a proper scale anyway. 1 FINN Height Unit (well, you can't see his feet) My daughter found her favorite, but alas we could not roll this one home. Moroccan tooth. Most likely Auriculatus. Fantastic price for such a nice tooth. They are normally quite beaten up. My other Moroccan finds. I love these for stocking stuffers The dealer I frequent from South Carolina. They are black water divers and have the best cetacean teeth and other bits and pieces. Great for school visits etc ... this stuff is sold by the pound. A sloth tooth partial. Mastadon (or Gomphothere ? .. probably a Gomph tooth) Tooth Cusp Extinct Billfish Vertebra Cheers, Brett
