Hey guys! I was in one of my favorite Pennsylvanian spots in East Kansas finding the usual brachs and bryos when all of a sudden this popped out at me. Any ideas as to what it might be? I’ve never seen something like this in my area before. Thanks.

I recently found these 2 brachiopods in the Pennsylvanian of eastern Kansas, I don’t really know my brachiopods. So could someone tell me what kinds are these? Thanks!

Is this a concretion that formed around a crinoid? Or something else? It's approx. 3in.x3in. The bottom half is smooth and the top half is rough. Holes at both ends. Found Riley Co, KS - Flint hills

I've been trying to narrow down the ID for bryozoans I've been finding. I'm not sure if they're weathering out of the Bennett shale or from further up. I have collected about 15 of these over the years and found a nice one several days ago. They are characterized by rounded form with flattish uneven bases. Spacing between monticules is about 1 cm regardless of specimen size. The below example is about 8 cm wide at base and 5 cm tall. I can't find it right now so can only show photos. I'll put a link below to my more recent find. All help appreciated!

Hey guys I had this collection of fossils and I wanted to show them to you guys. This collection has a few I have questions so about so please let me know about them. Heres the slideshow of the best ones. https://docs.google.com/presentation/d/1c9audycmGOHZENQjRdXumQot-0HE2oMJBl39AZoU5qM/edit?usp=sharing The most interesting one is this brachiopod, can someone tell me what is going on with it? Thanks!

Hey all! Im kind of new to fossil hunting, but in the 4 months I've been obsessed with it and have amassed a fair collection of local byrozoans, brachiopods, bivalves, and crinoids. But recently Ive been kind of short of fossil rich places and was wondering if you guys could give me some great locations within like 20ish minutes of Overland Park. Any help would be greatly appreciated.

I'm working on a really excellent mosasaur skull right now! I also read a 2014 publication by Johan Lindgren , Michael Caldwell, Takuya Konishi , and Luis Chiappe. In Convergent Evolution in Aquatic Tetrapods: Insights from an Exceptional Fossil Mosasaur they reveal some of the amazing details preserved on the famous Bonner Platecarpus specimen at LACM (LACM 128319) seen here: Like the LACM specimen, my new skull seems to have the same sort of differential phosphatization / preservation (?) of the scale pattern. Here is a figure from the article: Here are a few pictures of the parietal on the skull I am working on now: I promise I will share more pictures as the prep of this specimen continues! Until then, Merry Christmas! -KS

Found this on a gravel bar just below boundary to Permian but not sure about source. I had some trouble getting focused photo of edges. I'm thinking possibly algae.

Cottowood Mbr, Beattie Fm, Council Grove group, Permian. Western Greenwood County, Flint Hills, Kansas. I've found 6 of these in only in this one place. They are most likely the interior molds of the actual trace. They were discovered over a period of several months. They were found as tumbled out, not in situ. I'm inferring what's top and bottom due to some obvious features and basic physics. Some retain what appears to be an original edge around the top. The top diameters range in size from 5" to 10+", with heights from 2" to 6". These were found in an area disturbed by oilfield work where it looks bulldozed out for some purpose. Geologically, the area may have intermittently been shallow or shoreline. I've done an amateur's inventory of fossils in the immediate area and found highest numbers are of very! small bivalves.

Hello, all! Sorry I haven’t losted in a while. I’ve been busy with college this semester. Anyways, I recently purchased a fossil poplar leaf from my local rock shop! I’m pretty excited to have it on my collection! They say that it is Cretaceous in age, but I’m not sure. Part of me thinks it’s from the Green River Formation and is Eocene in age, but part of me thinks that the leaf is indeed Cretaceous in age. My reasoning for it being Cretaceous in age is because I’ve heard of fantastic leaf fossils come out of Ellsworth County in Kansas. The Ellsworth County area is part of the Dakota Formation, I believe. My question is: What age you think this fossil is add what formation do you think it came from? I tried to take a photo of it with my phone, but the photo came out crappy and I feel that the lighting was bad. I probably take better photos later on if you guys want. I feel like I should’ve also provided a ruler or something for scale, but I’m pretty exhausted. Let me know if you need a scale for figuring out the size of the leaf fossil. Thank you all!

Hey everyone I just got news of a recently described set of juvenile Tylosaurus cranial remains! This cranial material is from the Santonian Smoky Hill Chalk Member (part of the Niobrara Fm.) of western Kansas. What's really exciting is that this specimen (FHSM VP-14845) originated from a neonate (newborn) individual, which can reveal numerous details about mosasaur growth and ontogeny. I've attached the paper below: Konishi, T., P. Jimenez-Huidobro, and M. W. Caldwell. 2018. The smallest-known neonate individual of Tylosaurus (Mosasauridae, Tylosaurinae) sheds new light on the tylosaurine rostrum and heterochrony. Journal of Vertebrate Paleontology. DOI: 10.1080/02724634.2018.1510835. Abstract: We here report on the smallest-known, neonate-sized Tylosaurus specimen, FHSM VP-14845, recovered from the lower Santonian portion of the Niobrara Chalk exposed in Kansas, U.S.A. Lacking any associated adult-sized material, FHSM VP-14845 comprises fragmentary and associated cranial bones, here considered to represent a single neo- natal individual with an estimated skull length of 30 cm. Despite its small size, a suite of cranial characters diagnoses FHSM VP-14845 as a species of Tylosaurus, including the elongate basisphenoid morphology. At the same time, FHSM VP-14845 unexpectedly lacks a conical predental rostrum on the premaxilla, generally regarded as diagnostic of this genus. Further, the first and the second premaxillary teeth are closely spaced, with the second set positioned posterolateral to the first, contributing to the overall shortness of the dentigerous premaxilla. Because a conical predental rostrum is already present in ontogenetically young specimens of T. nepaeolicus and T. proriger with respective skull lengths of approxi- mately 40 and 60 cm, formation of such a rostrum must have taken place very early in postnatal ontogeny. Our recognition of a neonate-sized Tylosaurus specimen without an elongate predental rostrum of the premaxilla suggests hypermorphosis as a likely heterochronic process behind the evolution of this iconic tylosaurine feature. Partial pterygoids of the newborn Tylosaurus. Taken from fig. 4 of Konishi et al. (2018) Here's the paper - hope you'll enjoy it! Juvenile tylosaur skull.pdf -Christian

These are the most numerous former inhabitants(that can be seen with naked eye) in an area I'm studying. Cottonwood Fm, lower Permian, Flint Hills Kansas. There's an odd feature at the anterior end that may help ID it. Would these indicate shallow water environment?

Hey guys... First post here. I live around the Victoria area here in Ellis County. I've always been interested in our local history, but my interests have recently shifted to a little 'older' part of our history around here, more specifically when we were covered by warm-water oceans. I've spent a good portion of this summer walking creeks searching for SOMETHING, ANYTHING, and have came up empty handed. It's my understanding that the Sharks teeth and vertebrae will mostly be located in a specific sediment layer, and apparently I'm missing that. Can anybody help me out with identifying good places to search for these 'common' fossils that seem to be eluding me? Any help is greatly appreciated!!

What would the indicators be for a shallow or shoreline environment.
Innocentx posted a topic in General Fossil Discussion
I've been exploring a lower Permian site I think may have intermittently been a shallow marine environment. The location is Eastern Flint Hills, Kansas. What type and size of creatures would indicate a shallow or shoreline environment? Thanks ahead of time for any information. -
https://www.fhsu.edu/news/2018/08/fossil-data,-images-from-sternberg-museum-now-available-online This is pretty cool. Sternberg museum is putting everything on-line. The search function is awesome. They still have a lot of stuff to get scanned, but everything is at least listed now. This can be a great tool.

I would like to better understand conchoidal fracturing of chert/flint. I have many pieces where the fracturing is obviously conchoidal, but some others where this isn't obvious. I'll post photos in hopes that knowledgeable folks can point out circular characteristics that I'm not seeing. In this first one I can see small conchoidal divots. It's the larger seemingly straight(long lines) fractures where I don't see conchoidal characteristics.
