Identification Cretoxyrhina teeth are simple in design, having a triangular crown with smooth enamel and non-serrate edges, a thin lingual dental band, rounded root lobes, a lingual root protuberance, and no nutrient groove.1,2 Comments This tooth is from a latero-posterior position, given the crown's distal curvature. The chalk preserved this tooth very well - the enamel retains a sharp gloss comparable to that on modern sharks' teeth. References 1. Bourdon, Jim, and Michael J. Everhart. “Analysis of an Associated Cretoxyrhina Mantelli Dentition from the Late Cretaceo

I have recently found this fossil in north western Kansas (graham co.) I don't know if this is a shark vertebrae/cartilage disk or just a basic fish vertebrae. (Don't mind my bad prep work. I just started peeping fossils recently.)

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.

From the album: Sharks
A gorgeous tooth from one of my favorite sharks! The enamel isn't polished - the chalk preserves its shine extremely well - it's as shiny as when it fell out of the animal's mouth! -
From the album: Sharks
A beautiful tooth from one of my favorite sharks. This one is extra special because of the self-inflicted bite mark - a gash seen on the left in lingual view. Apparently their bite was strong enough to cut their own teeth! -

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)-
