Hey Everyone, Im new here and have a project for my high school science research class in high school. I have been analyzing microfossils from the Hell Creek Formation in Southern Montana and have been determining what species my specimens are from through published papers. There are some specimens however that I have not been able to determine, and have attached below. If you wouldn't mind helping me out, it would be greatly appreciated! Ps my apologies for no scale! The first two pictures are the same, looks like a pygostyle almost. Is 1mm long by 500 microns. The third photo I ha

From the album: Harding Sandstone
Chirognathus (Conodont) Harding Sandstone, Canyon City, CO, USA The "golden conodonts" from the Harding Sandstone. Conodont elements may have functioned as teeth similar to ours (though evolving independently of what would later become teeth in other vertebrates), or may have functioned as a filter apparatus. -
Hey all. I was wondering if anyone knew what this could be. Size is 2.7 mm by 1.1 mm. I was thinking some sort of bird based on the shape and the gradient. No clue on the specie though. The specimen is from the Hell Creek Formation in Northern Wyoming. Thanks!

From the album: Hell Creek / Lance Formations
Mesodma sp. Hell Creek Fm., Garfield Co., MT, USA P4 (4th upper premolar) Mesodma was a genus of multituberculate mammal that lived in the same environment as many well-known dinosaurs. It must've been a hardy animal, given the genus survived the K-Pg extinction event.-

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 u

Triassic Cumnock formation North Carolina Cyzicus and unknown plant?
fossil_lover_2277 posted a topic in Fossil ID
So I just made a trip to a publicly accessible creek that cuts through the Triassic Cumnock formation of North Carolina. Made a couple of nice finds. An unknown plant fossil, it’s worn down a bit, but anyone think they can ID? Also found a TON of what I believe are Cyzicus fossils, the largest are just shy of 1cm. Can anyone confirm these are Cyzicus? Thanks for the help!!!- 10 replies

Revisiting Spergen Hill, Indiana And Some Of Its Mississippian Micro-Fossils
dshamilla posted a topic in Micro-paleontology
This is my first "new topic" post to the FF, so I hope I'm doing this correctly. If you have a microscope or equivalent and a current or potential interest in micro-fossils, you might enjoy collecting at the following historic locality: Mississippian Salem Limestone, about 5 miles east of Salem, Indiana off Rt. 160; Spergen (Spurgeon) Hill, railroad cut (Manon RR) paralleling S. Harristown Rd, 0.75 mi north of Rt. 160; south end of Trackside Road; approximately 140 meters S of Harristown, Washington Co., Indiana; diminuitive fauna; Universal Transverse Mercator (UTM) coordinates: 16S 585024.- 9 replies

Anywhere Port Charlotte to grab micro-matrix? (coupla pics)
Mignoffo posted a topic in Fossil Hunting Trips
My son will be vacationing in Florida for the next week and a half with his grangmother. Since the Peace River will be off limits for fossil collecting due to seasonal high water flow, I was hoping he could grab a gallon of micro-fossil matrix from along the river. Does anyone know any sites along the Peace River or any other sites I suppose where I could send them to grab a scoop or two? One positive might be submerged areas might give access to spots that normally would be considered bank and technically illegal to scoop. Thank you for any help. Pics are just a few of many small- 1 reply

From the album: Permian
Dimetrodon sp. Wellington/Ryan Fm., Waurika, OK, USA Post-canine/posterior tooth This tooth is likely from D. limbatus, given the locality and presence of serrations: https://www.nature.com/articles/ncomms4269 The same paper also rules out other serrated Sphenacodonts by the enamel ornamentation. Its smaller size could indicate that it's from a juvenile. It differs from the comparatively abundant broken Orthacanth shark tooth cusps in the microfossil matrix (what most people are likely to confuse with): the enamel texture is not smooth, the c -
Hi y'all. Found this in some Permian micromatrix from Waurika, OK. There's no way I'm this lucky, but is this a very tiny Dimetrodon claw? I've tried to get access to this paper, but still waiting to see if the authors will send the text. I'm fairly confident it's at least sphenacodontid, based on pictures I've seen on the forum. It's about 3 mm in length. @dinodigger@jdp

Hi everyone. Tonight I'd Iike to share my most recent find: an absolutely tiny theropod tooth I found late at night sorting through what remains of the Aguja fm. matrix I purchased last year. I knew it would pay to be thorough and I was delighted to see the glint of enamel in a triangular shape eventually appear. Additionally, it has just taken the crown (no pun intended) for smallest theropod tooth in my collection, at only 2 mm in length and just over 1 mm in width. I'd be interested in reading your opinions on it's identity, I'm thinking either dromaeosaur or troodontid but I'm not sure.

Microfossil slides and more tiny shark remains from the Devonian
fossilsonwheels posted a topic in Micro-paleontology
I finally got some microfossil slides and I got some additional Devonian matrix from New York. I decided to go back to the Genundewa Limestone matrix primarily because I failed to find shark related matrix from other locations that are of the same age. Each of the three searches in this matrix has produced different results which make it fun to search. This search was a lot of Phoebodus teeth and some were close to 75% complete. Easily the best Phoebodus teeth I’ve found in this formation yet. I found a fair amount of Omalodus teeth and some nice ones. I also found two incomplete- 5 replies

Hi all! Most of you will know me as an invertebrate person, but, recently, I found something that may change my view! I was splitting some Jurassic Cotswold limestone, and I found a tooth. A tiny tiny tooth, which I believe to be a shark(?). In other chunks of the matrix, I found scales, and other hints to vertebrate life. It heavily fluoresces under UV light, and has these gorgeous lines along the flat crown. To the bottom right of the tooth, there is a partial mold of a brachiopod, which is pretty cool! Ancholme Group, Callovian - Oxfordian (166.1 - 157.3 mya). As a sister questio

I'm hazarding a guess as a P1 element of Idiognathodus?, or is it something else? seems a little wide for a conodont? Pennsylvania stark shale. Yeah or neigh? Thanks! Bone

Fossil forum, This is another fossil from the Leighton Fm. I just finished recovering it from some fossiliferous rock I brought back with me. It is about 575 microns long. Any help on its id would be appreciated. Here is a picture of it:

I put this on the microfossil forum as well, but wanted to give a look-see to this intriguing fossil! In my search for conodonts in Pennsylvanian stark shale (between Winterset and Bethany falls limestone) I routinely find concretions/nodules-most are powdery but sometimes i find teeth and other microfossils. Well much to my surprise, upon splitting my thousanth shale, I found a 1cm nodule, and within it, this apparent micro sea urchin-one of two in the nodule. From spine to spine (7:00-1:00) it measures just under 2mm in diameter I am refining my photog techniques with a
