I'm a fairly novice preparator and I was wondering if some of you more experienced folks could help me out a bit. I am working on a dipleura that unfortunately broke apart upon extraction. Some fragments of the pygidium were lost. I have the imprint and was considering casting the missing parts in plaster or something ideally reversible. My goal is to turn this fossil into a nice display piece. There are also some large voids in the matrix I would like to fill in. I've never done anything of this sort to a fossil before and I was hoping for some guidance on materials, techniques, etc. I have attached a couple of photos of the areas I would like to repair.

After Christmas morning everyone was preoccupied with their new gifts, so I slipped out of the house for a couple of hours to visit the Cole Hill Road site in hopes of finding a nice Christmas dipleura. The site was covered in snow and I had to hack away a large amount of frozen overburden. Overall, the rock was fairly barren until the last slab I turned over. Underneath that slab was a complete, prone D. dekayi! Unfortunately it turned into a bit of a jigsaw puzzle upon extraction despite my best efforts and I believe a couple fragments of the pygidium were lost in the slush and mud. L --> R In situ, fossil with scale, the fossil in full view, Cole Hill Rd. site covered with snow- I was digging on the shelf between the two cliffs I'll post more pictures once the jigsaw puzzle is reassembled and the fossil is prepped.

The title explains it but for a little more prepping or starting prep need to know roughly what it is before I can be comfortable in my work appears to have a rather odd placed general spine on the right and the head is not shaped like a holladrops. Thanks in advance Matt

Getting My Feet Wet In the Ordovician of Wisconsin and Iowa
RCFossils posted a topic in General Fossil Discussion
2018 was the year that I finally took some time to explore Ordovician aged sites in Southwestern Wisconsin and Eastern Iowa. Inspired by past forum posts (special shoutout to Caleb Scheer who was unfortunately taken from this world way to young) along with an invite from a fellow Fossil Forum member, I was able to make several trips into the fossil rich Platteville and Maquoketa formations. I was mainly focused on finding some of the amazing trilobites that these formations are known for. I also collected some nice representative examples of the various other fauna. Most of my experience collecting Ordovician fossils has been in the Cincinnatian of Indiana, Ohio and Kentucky. For those not familiar with collecting in the Cincinnatian, the vast majority of trilobites that you will find are Flexicalymene meeki along with lots of bits and pieces of Isotelus. One of the things that struck me right away in the Platteville and Maquoketa was the quantity and diversity of trilobite types that are readily found. While almost all of the trilobites will be fragments, occasionally you get lucky and find something complete. There is definitely a learning curve sorting through the various trilo-bits and learning to recognize the various species. Forum member Piranha was always willing to help out with identifications. My first trip out was in late Winter. I spent a day with forum member Fossilized collecting a few roadcuts in both Wisconsin and Iowa. The first relatively complete trilobite that I came across that day was also possibly my rarest find of the year. It is a very rare Cheirud: Acanthoparypha sp. Unfortunately the cephalon was gone but still an impressive specimen.

Well, It's been a while. After a hiatus that has seemed like forever, my friend Barrett and I decided to head to the Conasauga to find us some bugs as neither of us really had anything to do this weekend and we both wanted to do something. This was Barrett's first time, so I was effectively his mentor for the day. First stop however, breakfast of southern hospitality at a local biscuit place! After that, we went right to the site, getting into the nitty gritty. The river wasn't flooding over, but it was pretty decently high. Of course, that wasn't stopping us. We got into our big water-proof boots and jumped right in. Barrett quickly got into the groove, finding a certain section of the formation that was producing very large and complete Aphelaspis Brachyphasis with just about every swing of the hammer and chisel. Then late into the day, I found THIS beauty: I was stunned. I had never seen an exoskeleton on a positive that complete from the formation before like this, and for a second I thought it was fake. (sidenote, while transporting it to the car not long after this picture, a portion of the tailshield's exoskeleton unfortunately got peeled off by a very light breeze into the wind. At least I got a picture! Very fragile!) There was also a negative, though honestly it was completely outshown. In the end, we didn't take a whole lot, but we definitely took a number of really good ones, including some of the largest complete Aphelaspis I've seen.

Took some time to be done, but it was more about alot of small operations, than endless hours of pneumatic pen. All in all, the more time spent was with the dremel polishing the matrix. Before : Only operation before the picture was an emergency glueing on the field. Some time it s better to do this on the field, sometimes you better packed the different part of the puzzle home, clean them and glue them home. This time it was on the field. Then a bit of small chisel and a bit of pneumatic pen. Then a lot of dremel that will give the grey aspect to the matrix Then a bit of scalpel to remove a bit of matrix from the caudal spine. Then a bit of cutter to save one of the eodal' eyes from the counterpart. Then a bit of glue to set the said eye. And here we are :

Hi there! I've been lurking here for a while without an account, and figured its high time I introduce myself. My name is Jack, I'm a 3rd year geophysical sciences major at the University of Chicago. I'm fairly new to collecting and prepping. I do most of my hunting when I'm home on break in the Syracuse area of Upstate NY. My favorites to collect are trilos and cephalopods. I'm always looking for new spots and advice! Glad to be here! -Jack

Trilobite, Ammonite and Amber
Vallads posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hi, This is my first topic so, if i broke some forum rule or doing something wrong, please tell me, sorry. Also, english is not my native language, im trying to write correctly. Ok, im very very newbie in fossil subject but love science and decided to start my own collection. Well, i found this (pictures bellow). The owner received as a gift and has no extra information, just they came from a north america store's. Well, my main question is: this trilobite is real? What is that in her "head" (cephalon, right?) ? I mean, i know some cracks in fossils are signs of autenthicity but something like that? Maybe the original fossil is missing this part and the preparer tried to fix? Or it's normal? And.. its a phacops? (i know the picture is bad, not focused) How about this ammonite and amber? Are they real ? Thank you very much for any information !

Hello!!! I want to buy some trilobites. The seller send me these photos. What do you think? Fakes, good ones, not good? I don’t know nothing about trilobites... Thank you so much!!!!

Back at the end of June at our spot in the Thedford area a small group of us were busy making benches and unlocking slabs from the Widder Formation. Once we got to splitting, one lucky split resulted in finding three Greenops widderensis on a single plate. With flying genal spines and lappets on an already delicate and thin-skinned species, it was nothing short of miraculous that I was able to get it to the car with no damage. Right away I applied cyanoacrylate, and then it started to rain. This is how it looked in the field:

Just curios as to what species this is I looked at phacops but non seem to have such defined bumps for a better word also the eyes don't match up at least not to the ones I have looked at. Again questioning this id because what is exposed so far is rather small 0.86" by 0.80" and the size of the matrix block is 2.51" by 2.34" Also I am prepping this currently so not fully exposed yet don't know if that will hinder the possibility of confirming an id. Thanks Matt

Very new to all of this but find it very satisfying to nerd out on! I find myself day dreaming of the back breaking hikes to find ancient creatures in the rocks haha! All of my current finds have been from the world famous area in South West Utah near the city of Delta. And mostly aquatic plant and animal life. By far the most satisfying have been the incredible Trilobites! I’ve dug once at the very popular ‘U-Dig’ site, but I have a couple much more private spots that I’ve had incredible luck at, not only in quantity and quality, but also in the types of trilobites im finding. I’m always up for a trip to the west desert rock hunting! The area is also very abundant in quartz and other gems.
