What species of Tyrannosaur did this tooth replica come from?
dinosaur man posted a topic in Fossil ID
Hi I found this with the rest of my fossil replicas and was wondering if it could be a Rex tooth or another type of Tyrannosaur tooth. I don’t know if I can post this here or get an ID on it since it’s a replica but I got it at the Royal Tyrell Museum in Drumheller, Canada it’s a replica of one of there specimens. And I just wanted to know what it could be since it seemed strange to me on how skinny and long it is, Thank you!! -
I know it’s a internal cast of something but I can’t remember what.

For those that don't live and breathe fossils like we do, horn corals are often mistaken for horns, claws, etc. I knew someone who even swore the horn coral he had found was a fossil carrot, despite my insistence to the contrary. So after finding my best horn coral specimen ever (the largest one in this trio is about 9 inches long), I decided to make a cast of the specimen and "reconstruct" it to show people what they may have looked like when living. I know @caldigger will be very happy that there is now a horn coral action figure - complete with bioluminescence!

Possibly a burrow? Found beneath the Chinle formation on US89 in northern Arizona. 4 inches long, 2.5 inches tall, with a slight curve and a flatter bottom side. The rock looks like limestone, but was found on a flat wash without similar rock in the nearby area.

Here's a strange one. I found plentiful piles of what I thought were casts and internal molds in the iron-rich St. Mary's clay of Virginia last year. Loose clam fossils riddled blocks of talus. I was able to wiggle some out of their ancient resting places without s much as scratching the matrix. Generally that's because the shell disintegrated, leaving a void between the mold and the cast. If you look closely, however, what looks here like an internal mold isn't. The sculpture on the surface is clearly the outside of the shell. If it were the inside, you would see round protrusions where the ligament attached to a depression in the shell, not concentric ridges. Shown here is the most distinct of my specimens, but not the only one. Any thoughts? Mercenaria campechiensis, Miocene, VIrginia

Hello evereybody, I dont know if this is the right place to post this but I would be interested to learn more about mosasaur skull three-dimensional anatomy. Do someone know where it is possible to buy accurate mosasaur's skull cast? I am looking for something more educational than decorative and ideally not too big. I know that there are plenty of interesting stuffs on the web but from my experience in human medecine nothing is as good as a three-dimentional model to understand complex anatomical structure like the skull. Thanks for helping!

Commonly faked, hard to tell 100%
DevonianDigger posted a topic in Is It Real? How to Recognize Fossil Fabrications
So, I found this guy on the auction site, really only this one representative photo. These are often fake or frakenfossils, but I didn't see anything that screamed fake to me in this one photo. Just wanted to put it out to the room for other people's input. It doesn't matter as I basically stole it for 9$, so even if it's fake, I don't much care. Just curious what everyone thinks. (I don't have more photos, I just bought it this morning, this is just the provided photo. I'll be able to tell if it's fake when it arrives this weekend for sure, but the suspense is just too much, lol.) Also, it's about 5" long, not that that matters. -
While I was out cracking that last rock I found this in the drive is this a clam cast??? found in my drive from a gravel load west oh Houston Texas from Brazos river

This supposed real Cretaceous croc from Khourigba, Morocco is up for auction and, uh, isn't this just a painted cast with some real croc teeth thrown in?

Howling wind and deep ice cold water, but figured the creek bed would protect me from the wind (it did) and cold (not so much). Less hunters out. Don't usually post casts/steinkerns but this gastropod(?) has two small fossilized worm like things on it (probably need to get a better photo than the scan). All the rain has washed shells everywhere (lots of 5" to 7" scallops/ pectans everywhere; didn't see any whole ecphora, the only shells I usually pick up. Frilly oysters were everywhere as well; top half is neat). Most of the teeth I found was small or broken or both; three cow shark, one decent with root. Four(?) angelshark and several others, lots of spikes most missing their cusps, small triangular most with faint serrations, and a bunch of glossy drum teeth (photo is of the other side). Broken verts. When other stuff dries, may find something else interesting.

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!
