These were all collected last summer, from the Smoky Hill Chalk in Northeast Lane County Kansas. Any help/suggestions/corrections would be much appreciated. 1 12mm Long Enchodus? 2 13mm Long Enchodus? 3 20mm across Gillicus arcuatus? 4 Entire piece put together totals 48mm in length. Not sure on the genus. Better pictures to come. 5 29mm long Stratodus? Seems to bear some resemblance to strato2.jpg (790×562) (oceansofkansas.com). The other possibility I thought of was a damaged Cimolichthys.

We have been collecting for our first year 4H exhibit. These were all collected in Kansas in the Smoky Hill Chalk and also in Southeast Kansas around Greenwood, Elk, and Chataqua counties. We are looking for some concensus on our identification. We have had a hard time this year due to Covid. When we used to do this 15 years ago we would go to big meetings where we would get help identifying things. This year it was all identified on site and the leaders were very busy helping many people as best they could. As you can see we have already caught quite a few errors ourselves so we

Identification: ginsu teeth have broad lingual dental bands, rounded root lobes, a strong lingual protuberance in the roots of anterior teeth, smooth crown faces, and no nutrient groove. Notes: Has damage on the lingual side, perhaps a self-inflicted gash as the tooth fell out of the mouth. Otherwise, a perfect tooth with a very sharp point.

Reassessment of an iconic plesiosaur specimen
The Amateur Paleontologist posted a topic in General Fossil Discussion
Just received via ResearchGate a new paper (see at the end of this post) from "plesiosaur-ologist" Sven Sachs It's basically an in-depth description and reassessment of the elasmosaurid Styxosaurus snowii holotype specimen. The fossil consists of a beautiful skull, along with several articulated cervical vertebrae. The fossil was collected from the Chalk of western Kansas. The reassessment provides more insight into North American plesiosaur diversity and interrelationships. (+it has amazing pictures of the skull ) Sachs, S., Lindgren, J. & Kear, B. (2018)-

I found this Ptychodus marginalis on a sandbar on a river this spring after a large flood. The river cuts through the lower Smoky Hill Chalk of Northwest Kansas. After I picked it up, I asked myself "is this real?" It is!!! 54mm across.

This past weekend, my dad, brother and I were able to go out to Western Kansas to search in the Niobrara Chalk formation. We live in Manhattan, KS, so we had to drive about 4 hours to get to a suitable spot. A lot of Western Kansas is private property, so we had to look up GIS maps for Lane and Gove counties, which is where we wanted to search. Sadly, when we got there, one of the roads seemed to not exist; our map led us through the middle of some farmer's cornfield. It wasn't blocked off, but we decided not to take our chances. We started to look around in the area, and about an hour later,

Puzzle in poop - Cartilage, denticles or tooth plate in coprolite?
GeschWhat posted a topic in Fossil ID
I have been finding a lot of inclusions in a batch of coprolites from the Smoky Hill Chalk that assumed were bits of cartilage. One of the newer specimens from that batch had a piece of the material in question on the surface; enabling me to view it from the side. They look like little teeth, so now I don't know what I have. I have one other specimen that has a couple of the little tooth-like structures intact (one that I posted a while back that has possible Ptychodus tooth fragments). Is this skin with denticles, cartilage, a skull part or some sort of tooth plate? As always, any help is gre -
Ptychodus sp. tooth fragment/cartilage inclusions in coprolite?
GeschWhat posted a topic in Fossil ID
Hi all, I was going through some smoky hill chalk coprolites that I recently acquired and found one with some interesting inclusions. At first I was thinking these were skull fragments, but after looking at the Oceans of Kansas site, the only thing that I could find that had a similar texture were Ptychodus sp. teeth and what looks like cartilage. I have never seen cartilage in a coprolite before. I would think it would be easily digested, so perhaps it is just bone. There are also numerous fish bones and scales, so if our poopetrator did dine on Ptychodus, it had a diverse palate. I hav -
I just recently got back from a short trip to the Niobrara chalk formation and I need help preparing some partial fish fossils. Many of the bones are covered in chalk and they are extremely fragile. How should I clear matrix stuck to the bone without ripping off the bone itself? The one piece I am especially concerned about is a jaw bone that has chalk in between the individual teeth. I would really appreciate it if you told me how you would tackle this situation. Thanks in advance.
