    Conodont elements

    I was looking at some of my micro fossils with my microscope today I have a small collection of Conodont elements Palmatolepis glabra Chappel Limestone, Lower Mississippian, Blanco Co, Texas

    Another one from Calvert Formation sediments

    I encounter this one a lot in sediments from the Calvert Formation. This test batch is from a mudstone, broken up and reduced through no. 20 and no.120 testing sieves. The close up is using a 40/0.65 lens
  4. Hey guys, I’m looking for some recommendations for a digital usb microscope. I’ve heard Dino Lite is a good brand, so I’ve been looking at some of their models. The main thing I’m looking to use it for is examining and measuring dinosaur teeth and serration density. I was looking at the Dino Lite AM3113 model or AF3113T model, as I’m looking for something in the $200-$300 range. The only thing I’m worried about with that model is the picture quality as the resolution is 640x480. Another reason I was leaning towards the Dino Lite is because I’ve heard they fit snug in their stands, where I’ve heard some others like Amscope were loose in the stands. Does anyone have any experience with these models? What microscopes do you guys use?
  5. Hi all, I'm wanting to buy a microscope, so I can look at my amber inclusions more closely. I've been reading that a Stereo Microscope is the best to use. Is there a minimum the microscope needs to go up to magnification wise? I was to get as close as possible without breaking the bank lol I'm eventually wanting to photograph my amber. What do you all use? Can anybody recommend any models? It needs to have a light so I can illuminate the amber.

    Microscope enlargement

    Hello! I tried to look at a texture of a rock under a microscope to see if it's a fossil and I realised that I have no idea what's the right enlargement to see the unick texture that bones have. If anyone knows what is the right enlargement to see the texture of a bone under a microscope please tell me.
  7. Hello everyone, I'm looking for a professor in this field or someone with any sufficient knowledge in the matter of question, what can we obtain from looking at a tooth of an animal? The purpose of the question is to learn and design an Image processing algorithm that shall do the work for non-experts who would find a tooth of a fossil. So far, I've come to know it is easy to determine if the animal is carnivorous or herbivorous. But I don't know how to do it myself yet. Any help?

    New Microscope

    I just upgraded my microscope in the lab and what an upgrade! I have been using a cheap Amscope, fixed magnification scope for several years. At 10x, it is decent but stepping up the magnification really impacts the quality of the image. Amscope is good for an introductory setup but the limitations are readily seen when compared to a high quality microscope. After using a Lecia at the lab in Wyoming this spring, I spent the next 3 months researching and found high end microscopes to be generally well out of any normal person’s budget these days. Once upon a time, you could procure a used Lecia for around $5k. Those days are gone. The best I could find for one with the specs needed for fossil prep was $15k! Then, I found O.C. White’s website. They are typically used in industrial settings for detailed inspection of components. After some further research and a few emails traded, I opted for the Prozoom PZE4.5 with a 57000k variable LED light and boom arm. The standard configuration is the 1x objective with 10mm oculars. This yields a zoom of around .7x-48x. Great zoom but only 4” of working distance so, I also ordered a .37x barlow and 25mm oculars. This gives me approximately 7x-60x (according to the rep I worked with) and 10.5” of working distance! If you’re looking for an upgraded scope that doesn’t totally bankrupt you, this is the one.
  9. I decided that I had put it off for long enough, so recently I torn apart my work and rebuilt it at a proper working height. I also built a test blast box out of cardboard in order to better evaluate the usage with a boom-arm microscope. And lastly, my new Swift S7 microscope arrived!

    Biological or what?

    Is that a biological in the center (ribbed red object)? This is around 800X (scope = 10x object, 50" HD TV, no barlow, 1/2.5" sensor). About a 1/5 crop of a 5 mpx camera. Any Ideas?
  11. Inspired by @daves64 pictures, I decided to try out a Dino Lite for myself. I tried the AF4915ZTL model. I knew I wanted image stacking capabilities, which Dino-Lite calls Extended Depth of Field (EDOF), Automatic Magnification Reading (AMR) since an accurate scale bar was a priority and a long working distance for larger specimens so that helped narrow down the model. There are definitely pros and cons about it, but I'll let the results do the talking. Taken using EDOF: Taken using EDOF as well: Taken using the Extended Dynamic Range (EDR) feature: Taken using EDR: Taken using EDOF: Taken using EDR:
  12. Hello friends, a while ago I published some photographs of my fossils and they gave me the good news that they are real. But, now I bought others, exposed them to the microscope and I would love to know your opinions (the quality of the images and videos is not the best, sorry). The specimens are very small, the fish does not measure more than 5 cm and the pygidium of the trilobite measures much less and I don't know what species they correspond to Proyecto sin título.mp4 Proyecto sin título.mp4
  13. So I'm working toward a new goal of local petrified wood ID. I started working toward that goal a few months back but my viewing scope just didn't have the power (or working distance I might need). The good thing is I can use this new one for searching micro fossil matrix as well. I still have my B&L for prep but it doesn't have the power or capability of my new scope either. My new scope is an AmScope SM-4TZZ-144A-18M3. If I'm allowed I'll post a link but if not you can look it up. It does 3.5X-180X comes with a 18mp camera and a .5 and 2.0 barlow. The ocular are 20X and you get a single 10X. I'm still working at getting the camera calibrated after I was "done" I realized the ocular do not affect the camera view so I have to start over. I need the FOV of the camera apparantly. It's thanks to work gift cards (a perk I enjoyed this year especially) that I was able to get this. My out of pocket was about 1/4 of the cost. Anyway here are some photos I've taken with it. Maybe ignore the scale as I'm no longer sure of it's accuracy. The photos aside from the claw (found in Sharktooth Hill sand and the wasp eye are pet wood)
  14. I've found a lot of petrified wood around town and over the summer I cut of slices out of a few. I don't have the ability to polish them, so I put on a coating of nail polish. I then decided to put them under a microscope. I don't get a lot of magnification, just about 45x. This piece has some nice coloration and pockets in it, but it's even more interesting when you zoom in. I can't tell exactly what these dots are. They only look like this in a few regions on this slice, in other places they're empty as you can see to the right. Here's a more representative view. Unfortunately this is a much magnification as I can get. This next piece is one I posted recently. You can see lines going vertically across the screen, and occasionally there are black dots between the lines. I have no idea what those are. It's probably time to brush up on my plant biology. The structures are more apparent in the lighter sections.
  15. Hello Forum! I've been doing some reading on the forum about microscopes and I'd like to say thanks for the information provided, I've learned a lot about stereo microscopes and some of the things to look for. There seems to be a lot of used labratory equipment on certain online auction sites but my question is this; has anyone purchased, sight unseen, a used microscope and how was the experience? Are there specific things I should be looking for to ensure it's in good working order, or are stereo microscopes the type of product that potentially has lots of issues and is not worth taking the chance? Also when it comes to boom stands, are there any you'd highly recommended, because most scopes either have no stand or a traditional one. At this point, I could purchase a brand new entry level scope, or a slightly older Nikon or Olympus. Any thoughts you can provide would be greatly appreciated! Cheers, Ryan
  16. I have been examining my megalodon teeth and even Ramanessin shark teeth and under the microscope I can usually see (presumably) enamel that had been laid down in thin lines that always turn and meet the tooth edges at a 90 degree angle. It is easiest to see in fossil teeth where the mineral coloring brings out these whitish lines. It is hard to see in extant white teeth. Here are 3 photos of what I mean. The horizontal lines are from the middle region of the meg tooth along the tooth axis. The picture with lines going both side-to-side and up-and-down is from the region near the edge. The picture of vertical lines and the edge of the tooth is where the enamel comes to a 90 degree angle with the edge of the tooth. Heck, even my dentist got animated when I explained what I was seeing in shark teeth. Anyway, these white lines would be all but impossible to fake.

    Help with micro-photography

    Hey! As some of you may know, I am ever so interested in micro-fossils! @Tidgy's Dad can second me on this, they're awesome! As I'm preparing for my online palaeontological collection to go online, I keep finding more and more and more micros, ranging in size from sub 1mm to 10mm. (0.04 - 0.4 inch) My current set-up for documenting these teeny critters doesn't seem to cut the mustard - don't get me wrong; I'm making the most of it, but it's quite a hassle bending over a child toy microscope with a phone camera. A palaeontologist friend who I don't believe graces us with there presence here (shame on them...) recommended a brand to me, so I have looked into them, but can't find any that deal with a lower magnification required for these fossils - they all seem to be a bit overkill! If anyone could recommend me any other brand or model that seemed to work with them, or any tips, really, anything; send them my way! If you're going to recommend a brand or model, PM them to me, as we are not allowed to name drop sellers! Tips and everything welcome! I will be attaching some of my recent microscoped photos so you can get a better feel for what I am talking about!
  18. So for prep I generally use a Bausch & Lomb stereozoom 4 (probably my most versatile) and normal viewing I use a Celestron #4040 (likely not as versatile). Both stock specs from what I can tell. I am wanting to view the make up of chert basically. I want to see if I can see some that is made up of diatoms and sponge skeletons. Opaline chert often contains visible fossils of diatoms, radiolarians, and glass sponge spicules https://en.wikipedia.org/wiki/Chert#CITEREFBlattMiddletonMurray1980 I mean it will be cool to seem but I want to try and get some photos as well. Why? Well why not? Also I'm wanting some really good photos of the cell structure in some petrified wood bits. This is likely easier and maybe even possible already but it just hit me while I am asking about the chert thing. So my question is what lens setups would I need to get the best views? Is it even possible with one of the scopes I have? And to be honest I really don't understand the lens setups with scopes anyway. Anyone have a for dummies explanation of how changing the different lenses works? I do have 2.0 optics for the B&L if I choose to use them.
  19. Like @JohnBrewer , I also purchased a new toy from AmScope. I purchased Item #UHM350-11 "Tabletop Digital Microscope with Variable Working Distance and 11" Articulating Arm". This piece also have two LED lighting rings.This was a great purchase for $270.00 and about 1000 times better that the $20 Plugable USB Microscope that I purchased before. I set it up and unfortunately I do not have an Micro SD card to capture the pics. I am not tech savy, so I will have to study it for a bit and see if I can actually hook it up to mu computer. Right now I have it hooked up to my TV with the "provided" HDMI cable. I took a few pics and will post below- I will use a pic that I made with my I Phone and then I will show pics from the microscope. WARNING- I took the pics off of my TV with my phone, so they will not be as sharp as I am seeing it live. Hopefully they will look great when saved on a Micro card. I Phone Pic Picture shot off of the TV Here is a great example of a Mazon Creek concretion with 2- Sea Cucumber mouths. I Phone Pic-
  20. Looking to buy a stereo microscope to use with an air scribe and air eraser (in a blast cabinet) on echinoids and ammonites. This one seems very reasonably priced, but I have no idea what to look for in terms of quality. Will the image be blurry? Will I not be able to find any parts for this? https://www.vevor.com/collections/stereo-microscope/products/vevor-binocular-stereo-microscope-zoom-microscope-7x-45x-dual-arm-boom-with-led (price is about $250) If needed, I'll go ahead and buy an AMScope (dual boom, trinocular, and light ring) which comes to $576.94 on their site (seems to be the same price as online for the same model)
  21. I just recently came across a very helpful website: https://www.microbehunter.com/microscopy-forum It is a friendly site, and I’ve gotten quick replies to some very specific questions about a vintage microscope I recently acquired. There are a number of forums, including one for people looking to buy/sell parts. Some of the folks there have some pretty obscure old microscope parts if you ever find yourself in need of some. They’re also good for advice on how to setup and optimize your microscope.
  22. I haven’t gotten it in the mail yet, but I recently purchased an American Optical 569 Stereo star zoom microscope on a boom arm. I’ve been very excited about this. I just realized, though, that it doesn’t come with a light source! I will be using it to prep fossils I find. These typically span from a couple of inches to about a foot, including the matrix. Where I live in Iowa, I find mostly brachiopods, corals, and some crinoids. So far, I’ve been prepping with brushes, dental pics, an electric engraver, and a Dremel rotary tool. I would really appreciate any suggestions for how to illuminate what I will be working on when I use my cool new scope. Thanks much.
  23. Hello all I'm looking at purchasing a new microscope for my microfossils, I have been recommended Am microscopes. I was looking for a stereo microscope with a good camera for photos and measurements . I have narrowed it down to 12 Amscopes but im now a bit stuck on what I should look for or avoid if anyone has any advise that would be great. Cheers

    Prep microscope?

    So, I am starting to look into getting the required stereo microscope for doing abrasion prep work. I am not a rich man so going to hunt around for a bit before diving in. So far I am looking at a new AmScope SE410-XYZ. There are better ones listed with close to same price but those are auctions so price will probably climb still. Any here know this this machine? Is it decent or do I save a few more bucks?

    Florissant unknown (fish scale?)

    Hello everybody! I have another U.F.O here (Unidentified Florissant Object) and to be honest, this one has really stumped me! It isn't a carbon stain, it isn't one of those pumice chunks 'fireballs' that are common at Florissant, and it has a strange texture and shape. Weirdly preserved petrified wood? That is my best guess as of now... @piranha @Top Trilo @Tetradium The fossil is 1/2 an inch long. The first 2 pictures are the fossil by itself and the third I circled it. The rest are microscope pics of the texture. Pics 5,6, and 9 show the edges. 7 shows the top.
