Found this stone in Dallas area creek, are these fusulinids? They are supposed to be abundant in limestone in Texas, you can faintly see rings in them like a slice of onion.

Upper Campanian foraminifera from Northern Germany. We found in the quarry of Laegerdorf near Hamburg. We think it is a Lituola. What's your opinion ? It is agglutinated and the specimens have such areal, multiple openings. See more of our finds at https://foraminifera.eu/loc.php?locality=Laegerdorf+Neue+Heidestrasse

Hi all, Need some help with this ID! I found this fossil years ago on a beach in eastern North Carolina and it's been a mystery to me since. The best answer I could come up with is that these might be some kind of foraminifera (maybe of the fusulinid variety, though these don't seem to have the tapering at either end), but I'm not sure how to go about researching other possibilities. My camera has a tough time with close-up pics, so this is probably as much resolution as I can get. Thanks in advance for the help!

So I make slides of microfossils from ~ <1mm - 2mm. I use a glue that I make with food grade gum tragacanth and water as was recommended to me when I first started. However, I have always found it a bit annoying to make, get the consistency right and keep properly, especially as I haven't been able to find any definitive guides to this. I'm wondering whether any of you use gum tragacanth as well and have a ratio/recipe/advice for me? Or if anyone has had good success (long lasting, dries clear, secure, fossil safe) with any other type of glue? Thanks!

Good morning all!- hope you are all healthy! I found these foraminifera (my first!!!) on April 20, but took my time fishing them out of some limestone, then meticulously cleaning and prepping them. Thanks to Clear Lake for suggesting, in my first post that it looks similar to Ozawainella ciscoensis-really appreciate it! They were all found in winterset limestone in Kansas City. Researching numerous references, I found it is far more complicated identifying them, so I'll send them to someone with more expertise in i.d.s! , and am leaving them as simply Foraminifera. I i.d. them under a dissecting scope, then used 30 gauge needles to loosen them with applications of vinegar, then washed them in alternating vinegar and water, then placed them on blue clay to make them stick in place. The best one has 4 views. Just received my digital microscope and love it!! So simple and easy to use! My previous post stated it measured 458um or so, but I used the wrong objective- all of these are 860-900um in diameter. I went ahead and placed them on the fossil of the month, only because I haven't seen a lot of images on them in the forum (though I'm still looking through ).Thoughts and suggestions appreciated, and thanks for making me feel like a kid again! Hope you enjoy!- The beauty of some things simply cannot be appreciated unless you look closely!!!! Bone

Good morning all! While I was magnifying a shell which looks similar to a modern scallop I noted several discoid shaped objects in the matrix, so I cleaned them away and these are the best pictures I have so far. It measures 458um in diameter and is heavily crystallized. It is a very fossiliferous Pennsylvanian layer is all I can i.d. On the right track or way off? I have both sides depicted but the edge also has small "pores"/discreet nodules but can't get a pick of that yet. I will try to get some better pictures too. Thanks for looking and comments appreciated! Bone

This sample was stained by rose bengal solution. it was sampled from the intertidal zone in Apo reef natural park in mindoro, Philippines, around >5m depth. I'm confused on what species is this. I have no other pictures since we are under a community quarantine here in Manila so I have no access with my microscope.

Help request! I am putting together a tool for judging rock age based on very crude, whole-rock, hand-sample observations of fossil faunas/floras -- the types of observations a child or beginner could successfully make. I view this as a complement to the very fine, species-level identifications commonly employed as index fossils for individual stages, biozones, etc. Attached is what I've got so far, but I can clearly use help with corals, mollusks, plants, vertebrates, ichnofossils, and the post-Paleozoic In the attached file, vibrant orange indicates times in earth history to commonly observe the item of interest; paler orange indicates times in earth history to less commonly observe the item of interest. White indicates very little to no practical probability of observing the item of interest. Please keep in mind that the listed indicators are things like “conspicuous horn corals,” purposefully declining to address rare encounters with groups of low preservation potential, low recognizability, etc. Got additions/amendments, especially for the groups mentioned above? Toss them in the comments below! Thank you..... https://docs.google.com/spreadsheets/d/1tVm_u6v573V4NACrdebb_1OsBEAz60dS1m4pCTckgyA- 5 replies

Scientists use ancient marine fossils to unravel longstanding climate puzzle by Cardiff University https://phys.org/news/2020-01-scientists-ancient-marine-fossils-unravel.html Ancient marine fossils reveal how rising sea levels trapped carbon in the oceans preventing extinction-level global warming 14 million years ago. Fossil records suggest high levels of carbon was captured in ocean sediment. Significant volcanic activity had previously led to extinction level events.

I really like the shape to these. I have come across sites with photos of these but I can't seem to find any info about them such as what period they may be from. These microfossils are harder to research than they are to find...phewww.

To Rumi: Thanks for the ID of the elphidium ...The specimen in the last post was the largest I came across, it was about 1.5mm, all the rest are well less than 1mm. Are these smaller ones in this post of the same species? Thanks....

Hi Everyone, While this is not a fossil, it is a very large benthic foram that I am having trouble idenifying. Could anyone either tell me what this is, or point me to somewhere or someone that could help? This specimen is not whole, there is an outer ring on the other specimens like this, that is a slightly different pattern to the one seen here. These are up to 2 or 3 mm across. I have found them in VERY high abundances and need to figure out what they are. Thanks!

Hi everyone I think I just found a new hobby With my latest fossil delivery I recieved quite a lot of microfossils & matrix vials as the world of microfossils was something that I have been long interested in. So a 2 weeks ago I finally ordered my first microfossils for which I reserved a special drawer in my archive cabinet. So here is a recapp of what I all got: 3 vials of permian material from Waurika, Oklahoma 1 vial of permian material from The red beds of Archer County, Texas 1 small vial of Conodont rich Mississippian material from the Chappel Limestone formation, Texas 1 small vial of Cretaceous Lower Gault Clay, East Wear bay, Folkestone, Kent, UK A micropalaeontology slide with Jurassic Blue Lias matrix rich in holothurian material. A thin section of an Ostracods filled Elimia snail from the Green River Formation in Wyoming A thin section from the Rhynie chert of Scotland which should contain preserved parts of the plant Aglaophyton major and perhaps even other species. I also got a lot of Bull Canyon micro fossil teeth and 2 cretaceous mammal teeth from Hell Creek In this topic you will be able to follow my path through this newly discovered hobby as I will post my finds and progress Currently I am only working with a clip-on cellphone microscope, but I do plan on getting a professional microscope in the next few months! (Tips are always welcome) So let's put on our Ant-Man suit and explore the microfossil realm So here are some of the first pictures I made of some of the microfossils Starting with the thin slices! Thin slice with Ostracon filled Elimia tenara snail from the Green River Formation, Wyoming Thin slice with Aglaophyton major from Rhynie Chert in Scotland

I'm heading down to Newport Beach, CA- south of LA. Does anyone know of micro-sites there with access? I'm also looking for information on local stratigraphy there. Any on-line resources that you could recommend? I'm new to collecting- and have been learning a lot from reading previous related posts. Your suggestions and advice are welcome.

What is the identification of the foraminifera present in this section? We suspect it as assilina but we think this should have a younger age instead. Thank you!

Cephalopods, trilobite, other invertebrates, Permian reef slope (Guadalupe Mountains National Park)
verydeadthings posted a topic in Fossil ID
Hi guys! This is a continuation of a previous post focusing just on the sponges. These fossils are from the Capitan Formation, which is Permian Period, Guadalupian Epoch, Capitanian Stage. Because these fossils are in the park, no collecting was allowed, and I can't provide additional images. Any confirmations about the identification or suggestions about a more specific identification are welcome. This trilobite is the only fossil out of these images that was actually found in Carlsbad Caverns, right behind the elevator. Can I get more specific on an ID? Cross section of rugose coral? Sponge? Bryozoan. Acanthocladia? Bryozoan? Crinoid.

Hi guys! I don't post here often, but I'm a PhD student in geology, currently working on tropical Paleogene palynology. I'm taking an unrelated class on the Permian Basin and I am working on identifying some of the fossils our class saw in Guadalupe Mountains National Park. I'm not a sponge expert, and I was hoping someone on the forum might be able to confirm or correct my identifications. I might make a follow-up post on the non-sponge fossils we saw on the trip. A bit of background, these pictures were taken in the field with a metric scale, the scale has been cropped out of the pictures and a 5 mm scale bar is added. No fossil collecting was allowed on this trip so I won't be able to provide additional images. The fossils are from the Capitan Formation, which is Permian Period, Guadalupian Epoch, Capitanian Stage. The global stage name is actually named after the nearby El Capitan peak. Amblysiphonella? Archaeolithoporella?
