I picked this bit of oyster shell up because it has pretty barnacles on it. I started cleaning mud out and a chunk fell off revealing this. I thought maybe a gastropod cast that's settled in, but it looks attached? It's also not evenly spiraled. It doesn't show in the pictures, but the fatter section has an undulation to it. Worm cast? Anyone know what it is? (Sw Florida)

Hello, I am reluctant to post this because of the flame I might get. I don't know how else to interpret this "rock". I can't believe it left as much detail as to even have the pink spot at the end of the trunk. Where should I go from here?

I wasn't sure if this was a rock or a cast. I just found something in the first two photos. It looks like a mineralized blood vessel. Can anyone confirm that?

This is a particularly fragile type of shell, made of many fine layers, and is prone to disintegrate as these did. This rare steinkern was found on a block of matrix submerged in the Chesapeake Bay. Dimensions are for the best-exposed steinkern on the block. The entire block is 14 cm wide x 10 cm high x 5 cm deep.

Please clarify for local discussion. Referencing the attached sketch: First is a coin simulating a fossil. If split at the red line, there would be 2 pieces of external mold. Correct ? or incorrect ? Second is a lens shape, like a saucer or moult of a pygidium. If split at the red line, there would be 2 pieces of external mold. Correct ? or incorrect ? Third is an egg or complete bivalve. If split at the red line, there would be 2 pieces of external mold and 1 internal mold. Correct ? or incorrect ? All 3 assume that the specimens have dissolved an left a void which if filled would be the cast. Correct ? or incorrect ? The local argument is that the pygidium moult example is 1 external mold (top) and 1 internal mold (bottom) because it is the "internal" side of the animal. I don't think that is correct. Just a local discussion needing clarification, thanks. ref: http://www.ucmp.berkeley.edu/paleo/fossilsarchive/casmol.html

Area found, Ay Athanasios, Sfalagiotissa Area, 10km north from Limassol shore its 5cm diameter shell-shape 2cm thick. on top there is a dent, when wet a red shell-like shape appears. in photo 1 it is slightly visible on the left. bottom i can see at least 2 shell casts, which means there were shells under and there are shells on top. Anyone thinks I should try and extract that red one from the top? And if yes, any recommendation apart from scratching my way around hoping for the best? All over that area, I found many sponges, shells and other reef fossils, that I will post here at some point.

Last Saturday I decided to try something new. I had made a couple of plaster casts in the past, but NEVER painted any before. I don't like painting the walls in my house so never though I would enjoy painting a replica but by golly it was a BLAST! To start with the casting I made 5 teeth, and 3 broke, but 2 came out somewhat decent. I decided to paint my 3 broken ones first just to try it. The fourth tooth in the pictures is a REAL fossil rom Hell Creek, not a cast! I did not have it with me while I was painting so I was just trying to go off of memory. I used a matte sealer for the root, and a high gloss sealer for the crown. They both have a shine to them though! Tell me what you guys and gals think! I promise I won't be offended, in fact if you can offend me you have done something no one has done before! Hmm which one is real? Nope not this one. It could use a little more blending at the crown and root I think. The mold I used seems a bit fabricated from the real deal, but it looks nice! I think the white I added on the tips bothers me the most, but I was trying to give it that shine. Lets see what the real deal looks like. Not the greatest trike tooth out there, but its nice! No idea what is going on with this side of it. A little enamel peel, but it is to be expected. I thought I remembered the crown being darker? Eh, its still a cool piece!

Near Crosbyton, TX found what looks like a piece of chewed gum. I'm thinking the inner mold of a bivalve or maybe just an very interesting rock. Thought?

Good afternoon, I found this along the creek's edge near Del Valle Texas. Both sides are somewhat uniform. Plenty of shale formations nearby. Thanks

I recently bought a Do It Yourself Psittacosaurus skeleton cast. And I thought it would be fun to share the process of mounting the skeleton. I already had a skeleton cast of a juvenile Psittacosaurus but now I also have an adult version! As it came painted, I could just have mounted it as is. But I wanted to give it a more interesting post rather than a a straight spine and tail. Since the spine and tail come in bundled segments of vertebrae. I thought I would cut them apart so that I could create curves better. And as I was modifying it anyway, I might as well improve it here and there as well. Some parts like the vertebral foramen on the vertebrae and some fenestra are filled in on the original cast. So I decided to dril some holes to make the details a bit more accurate. Size comparison with the adult and juvenile skeleton. The frame I made for the juvenile is pretty basic and primitive so I want to make a better and prettier mount for the big one. Drilling out the vertebral foramen in the middle and separating the vertebrae. Process of drilling holes and opening up the inside of the skull to more accurately reflect actual openings in a real skull. I'm not done smoothing out the new hole syet though. So right now it still looks quite ugly. More to come soon!

I've started to put together an entry for the "Paleo Re-creations" forum but it will take some time to get all the info entered in and ready to post. My first step has been to create a gallery. I've begun to garnish it with information regarding each plaster or resin cast. Currently, I have the album loaded to the gallery titled "My fossil replicas (casts in plaster and resin)." My Isotelus replica has comments attached now. I'll provide information about each image via comments. Upon completion of that task, I'll write a short article posted here on "Paleo Re-creations" describing my successes and failures so that we can have discussions regarding making fossil replicas as amateurs. I am looking forward to learning a great deal from each of you on this subject. What I know I will happy share with all of you. Bill Heimbrock - billheim@cinci.rr.com

From the album My fossil replicas (casts in plaster and resin)
This is a plaster cast of an Isotelus maximus trilobite from the Late Ordovician of Cincinnati, Ohio that I produce for my fossil club for sale at gift shops in the area. 100% of the money goes to the club and I bill the club for the materials. Sales have been kind of slow. It's not a popular item for some reason. Not sure, but my hand paining is a little splotchy and I guess people have been desensitized to replicas because of mass production. The plaster is just plaster of Paris I buy in a big bag at hobby stores. I first spray paint the whole thing, top and bottom with grey primer. After a couple of days, I use masking tape to cover the top of the shale, leaving only the trilobite exposed. I then spray paint it with dark taupe and then with the same paint in dark brown. I immediately wipe most of the dark brown off with a paper towel, leaving the darker colors in the grooves the same way you would see it look on a real Isotelus trilobite. A final touch before removing the masking tape is to buff the trilobite with a shammy cloth or lint free cloth. Yes, I have to touch up the shale with paint after I remove the tape. The tape does not do a perfect job of masking these fine details. Send questions to the Paleo Re-Creations Forum.© Bill Heimbrock and the Dry Dredgers

Hi, can any members help me identify this fossil gastropod I bought a few years' back from a junk shop? I don't know its age or its location. It could be Jurassic from Dorset, southern England, but that's only a guess. So, too, is my own identification, that it's an inner cast of a homotoma. No idea as to the species, though, and it could well be something else. Any sea slug lovers out there?

I understand why collectors seek genuine fossils over casts, but sometimes I really do wonder why some people have such a tremendous disdain for casts and replicas. I had recently went to the local dinosaur museum exhibition with a group of colleagues, and one of them was rather startled once he learnt that the majority of fossils being displayed were casts. In his own words, he felt like "he was scammed". In another case which irks me, I was teaching a group of children about various fossils. Most of the fossils I was using were real except for a few teeth which were casts. A 5-year old girl happened to be holding one of the casts, and asked me if it was real. When I explained it was a cast, she exclaimed in a most disgusted voice, "Ew! Fake!" and quite literally slammed it back down onto the table. (I was just as shocked at her lack of manners, as I was at her extreme reaction). I am not asking for collectors to switch to buying casts, but how do we convince the general public that casts are very important, and that they are here to stay?

This one came from Arizona, near Ash Fork, Yavapai County. Cretaceous... I think... However, the underside looks like something else, almost looks like underside of Turtle Shell.. What do you think?

As far as I am aware, the vast majority of folks here have fossil collections that were dug up by yourselves. But what would you say to casts and replicas? For most folks, it is snarge near impossible to own the skull of a Tyrannosaurus Rex, or the imprint of a 2.5 feet long Meganeura dragonfly or a 6-inch Megalodon tooth. Thus replicas and casts come into the picture, and many museums and exhibitions use reps and casts as well. Would any of you purchase casts or replicas?
