Kansas Shark Tooth

[chg057]

I found this shark tooth yesterday in the first chalk bench of the Fort Hays Member of the Niobrara approximately one foot off the contact of the Carlile Shale (my first keeper from the Niobrara). I was able to prepare it as best I could this morning and realized it doesn't have a root. This was my first matrix prep of a fossil and I'm pretty pleased with how it turned out. 

 

I was hoping someone could help me identify it. I think the photos look at the lingual side of the tooth. 

 

Also - since it's imbedded in chalk, it is beginning to separate from the matrix. Does anyone have suggestions for helping affix it to the matrix? I would superglue it but don't want the glue to affect the overall appearance of the enamel. 

 

Thanks!

What time period is this formation? My first impression is Mako but I am not familiar with this location.

It's early Coniacian - approx 89.5 Ma, Western Interior Seaway.

Compare with Cretodus...cool tooth.

I cant comment on the species, but nice find and nice prep on it!

That chalk is rather fun to work with!

Hey thanks!

I'm not really seeing Cretodus.  Perhaps a Protosphyraena tooth?
