At 1400 hours on 10/13/2018, I collected a number of specimens from the Tullock Member of the Fort Union Formation. The location is about a mile north of Miles City. The rock is fine silty clay with leaves and twigs mixed into the sediment. Above the strata is a layer of cattails forming a matted layer. Source for leaf identification came from Reproductive and Vegetative Organs of Browniea gen. n. (Nyssaceae) from the Paleocene of North America Article in International Journal of Plant Sciences, February 2007.

Hello everyone, New member from Minnesota, post my intro in the member introduction forum. The first is my Minnesota fossils. From the Cannon Falls and Rochester area from Ordivician period. The first is a Cephalopod from Rochester. One other from Minneapolis area from Ordivician. Apologies but most of it is unprepped at the moment Will have to post images in multiple posts. The Second will be my collection from Iowa. I have stuff from Montana that I will post in a different thread.

This is a plate of Productus brachiopods with spines collected from marine sedimentary brown-red clay shale, which sits on a bed of breccia limestone. Location is slope above rest-stop on east side of Highway 89 N about two miles north of Riceville Rd. in central Montana. Was collected on Jan 21,2019. Prep work was done by collector David C. Powers.

Taxonomy from Lund 2000. Diagnosis for the genus Discoserra from Lund 2000, p. 180: "Teeth of the premaxilla, maxilla and dentary long, thin, and styliform. Posterior end of maxilla does not extend back to level of anterior margin of orbit. Parietals excluded from contact in dorsal midline by postrostral 2, which contacts supraoccipital. No transverse supratemporal commissure in supraoccipital. Two rows of paired bones over orbit. One to three interopercular bones; two to three small postspiraculars and a presupracleithrum. Branchiostegals very variable in size, number and shape. Dorsal ridge scales with small, forwardly facing hooks; two to three small anal fin hooks. Origin of anterior edge of dorsal fin set well below dorsal margin of ridge scales. All fins with well spaced rays; pelvic fin reduced, caudal fin rounded."

Is this a real T-rex metatarsal
Oxalaia posted a topic in Is It Real? How to Recognize Fossil Fabrications
It is 47 cm in length and has a little restoration. It is from the Hell Creek formation in Montana.

This Troodon tooth is one of my favorite fossils in my whole collection. I found this at a microsite in Northern MT in the summer of 2017. -

Looking for a little help identifying this Hell Creek vertebra I purchased a few years ago. I bought it off an individual with lots of experience hunting in Hell Creek, but unfortunately he had no idea what it might be from. Any help would be much appreciated!

I need an ID for this clam. I found this clam in a concretion. it was taken from the Kevin member of the Marias formation. Th Kevin member is listed as Santonian Cretaceous. The location is 5 miles west of Loma Montana.

Specimen was collected on Oct 13, 2018. The location is Cedar Creek. It is 7 miles south of Glendive. The area is Pierre Shale. The specimen was in a concretion.

I found this brachiopod as float on the side of the road. It was very near the transition of Devonian to Mississippian Lodgepole Formation in Little Belt Mountains, in Montana. The fossils is large. I'm thinking it might be a spiriferida.

I collected this Leptaena brachiopod from the red brown mudstone resting three feet above the top of the first out crop of breccia limestone. The location is above the rest-stop on highway 89 S before Riceville Rd. The formation is the lower part of the Kibbey. Leptaena Brachiopods dominate along with three types of bryozoa and crinoids. Also found clams and a part of a plant fossil. The setting was once a lagoon.

Hey there I was prepping a plate of Baculites when I noticed what looking like a bone. At the time int was hidden under a crust of calcite. After removing the calcite I now need to gather ideas on what kind of bone this maybe. So, I am looking for some ID help.

Found in the Judith river formation of Montana. Mule deer or something older?

I spent a few hours fossil hunting on two separate trips on Forest Service land in Montana. The first trip was this past spring looking for Late Oligocene - Early Micoene flora about 90 minutes outside of Missoula. The second trip was during at stint over the summer at a fire lookout tower in the Flathead where I spent just a few hours one morning looking at Devonian and Mississippian marine layers. Besides the obvious, the trips were quite different. The spring trip was a drive to a road cut on a Forest Service road while the summer trip was a seven mile hike in. Additionally the medium is completely different; flakey, brittle shale compared with big, blocky limestone. You can keep non-vertebrate fossils as long as you don't plan to sell them. Prior to heading to an area, I look through publicly available research, lectures, field trips, etc. to find possible localities. I only found limited information on possible identification of the Late Oligocene - Early Micoene flora and most of if was unpublished graduate work from a nearby site with only some overlap on species. Please feel free to correct any id's or throw new ones out! I believe these are cercocarpus, a mahogany.

I was seven miles south of Glendive; Montana on October 12, 2018; time 1400; exploring a drainage cut into the Pierre Shale Formation while looking for concretions. This scaphites was partly exposed on the surface of a concretion. Later, I removed most of the surrounding matrix.

From the album: Invertebrates and plants(& misc.)
Debris, including micro glass "beads" from melted earth ejected into the air, from the KT boundary burn layer. Garfield county, Montana, Hell Creek formation. Late cretaceous (duh) *i added "misc." to this album because this didn't fit anywhere, and I thought it was really cool and should definitely be included somewhere. **There could even be vaporized dinosaur material as part of the glass and melted debris included. There definitely was plenty of it, but I guess realistically, unless it became evenly spread into the atmosphere and airborne debris, this is too small an amount of ejecta, and by percentage such a minuscule amount of vaporized dino, so sadly there probably isn't any.
