Been finding a lot of these tiny spiral shells. While some are definitely gastropods this one looks similar to some forams I’ve seen. Would love to know which this one is! Thanks

I was given this microfossil, which has no provenance whatsoever. Any suggestions would be most helpful.

Hi! I’m still trying to identify one fossil from a particular unit of Pleistocene/Early Holocene lacustrine silt from my hometown of Saskatoon, but I figured I would look away from it for a bit to try and identify another fossil from the same unit I’ve been unable to classify. I have two specimens, both apparently of the same species. They are both approximately 0.5 millimetres across. They are perfectly circular, with lines radiating from the centre and rings of alternating colours (possibly representing growth lines). One specimen is photographed dorsally, showing its circular shape, the other in profile, showing its umbrella-like, protruding outline. All photos are taken through a microscope with my best camera currently available, an iPhone! My main areas of middling expertise are arthropod and vertebrate fossils, so I have no idea what this is! I have briefly studied fossil foraminifera and diatoms in the past, but it looks like nothing I’ve seen in those areas as well. It reminded me of a small limpet, some type of seed or spore, or perhaps even a strange fish scale, but I have no formal suggestions. I’d highly appreciate any help! I will try to supply any additional information you may need. Thank you!

Yesterday I found two strange forms in the same stone. It is from middle ordovicium. Could they be foraminifera? Here is one of them Martin

Can please someone help me? I found this fossil from an middle ordovician place. Could it be a horncoral or a foram with a spiralform? The specimen is about 2 cm in diameter, some parts hidden in the stone. Any help very appreciated.

Hello all, I believe that one of these is a foraminifera, not too sure if that tiny bivalve and snail would be considered one or not. Anyone have any ideal what period these may be from? Was digging some old bivalves and gastropods out of some sandstone and came across a boulder that had hundreds of microfossils mixed in it's debris. The size range from what you see here to less than 0.50mm. Some if this stuff is really cool looking.

I've frequented this forum for almost 4 years but never signed up, so let me introduce myself. I've been (as most of the people around here I suppose) interested in the life of the past since my childhood. In particular micropaleontology captured my interest: we coud trace the story of our planet studying something as little as a foram, simply amazing. Also, many thanks to all the people in the forum who make me discover new things every day

Here are a few micros from the Miocene of Beaumaris in Victoria, Australia. Sorry about the horrible pics as per usual... All of these were found in matrix that was inside a bivalve, some interesting stuff can also be found inside larger gastropods and brachiopods. I'll post more eventually. #1. Teeeeeeny little foram. Should probably also mention that the ruler is in millimetres. #2. Bryozoans ......

I was out hunting near Spring Valley, Minnesota with @Bev and @minnbuckeye the last couple of days. As always, I was looking for coprolites. Mike came across this first piece, sitting loose in a piece of weathered matrix. While we were splitting rocks, we found a virgin layer of the source matrix. When we got back to Bev's fossil barn (everyone should have one), I took a peak under the microscope at two of the loose, irregular objects but couldn't really see much because of the powdery iron oxide coating. When I lightly rinsed them, they revealed these microscopic (calcareous) jack-shaped objects. Similar inclusions were in both objects loose objects. You can see from the broken spine on the inclusion in the lower right that they are hollow. In the other loose piece and those still embedded in the matrix, I can also see random straw-like spines of the same material. I'm not sure if these are coprolites, algal masses or something else. I have seen coprolites covered in powdery iron oxide before. Eventually I would like to free more of these from the matrix so that I can sacrifice one to get a look at the interior. Can anyone identify the little jack-shaped inclusions? The spines may have been quite a bit longer. The only things I can think of are forams or perhaps diatoms. Bev and Mike - What was the name of that cliff again? Decorah Shale? @Carl

Hi all, So here is a foram that I found in the Santa Fe River in northern Florida. I got told that it is either Eocene or Pleistocene. Well I know absolutely NOTHING about forams (the fact that they are single-called still confuses me! ), so I ask your help: what species is this one, how old is it, and how exactly would it have lived/looked like when it was alive? Thanks in advance, Max

Samphire Hoe, Sussex is not far from Dover and was created by dumping stuff from the digging of the Channel Tunnel. It is a wonderful nature reserve, has a small shop/café, access to the beach and chalk fossils are easy to find on the surface of the fallen blocks. Mobile phone service is a bit weird as my phone connected and said Welcome to France, but Dutch tourists there had English connection. Good job there is a pay phone. Here are just a few of the bits I took a photo of. Not completely prepped yet but you get the idea of what can be found. Some are micro fossils from the dust as chalk easy to break down or scoop up from the bottom of the cliff. 1 - common foram 2 - Ramulina foram 3 - Tiny tooth next to Tritaxia foram ( let me know if I have got my ID wrong) 4 - Fish scale 5 - Bivalve with encrusting bryozoa 6 & 7 -Onchotrochus serpentinus Corallite overhead view and of one end confirming not a serpula 7 to 9 - What I think is shed isopod skin, NHM could not ID it but then they sent it to the fish department.

. The Belgium Nummulites sp.that I have are 5 - 10 mm.
-
The French N. laevigatus specimens that I have are 2-17mm in diameter. .
-
My specimens of this species are 2-3mm in diameter, and the thickness in the center is about 2/3 of the diameter. Thickness on the edge goes down to about 0.1mm. .

Ive been looking over some Platteville plates for a trade with a member, but I am having issues with finding access to some images or papers. The image or paper i'm looking for is on a middle ordovician foram, Reophax blackriveranus n. sp. thats found in the Platteville formation- Mifflin member. Papers on other forams found in this formation would also be appreciated. If anyone is able to assist, I would be grateful. Thanks! Best regards, Paul

Got a snall sample of so-called "star sand" from Taketomi,Okinawa,Japan, that was loaded with some of (I think) the most beautiful forams: 99% of the sample consists of 2 species, Baculogypsina sphraerulata & Calcaroides spengleri; Went thru my inventory of forams & found some examples of their fossil kin: unfortunately, like any other fossil, the Miocene & Cretaceous ones have suffered a lot of wear & tear, but hopefully you'll be able to view & compare. Don't know if the images do them justice. Each foram is about the size of a grain of sand. [attachment=18991 8:foram1a.jpg]
