MusicalMommy Posted April 16, 2012 Share Posted April 16, 2012 Hello, I came across this interesting find in our landscape river rock in our backyard. It looks porous on the flat bottom kind of like bone, but has a rounded top and some interesting raised lines on the surface. A friend brought it another friend who identified it as a stingray tooth. But... when I looked up photos of stingray teeth I found mostly flat ones with parallel lines and not any that had rounded lines on one end more like a finger print. I was just curious if anyone could give me a second opinion on the identification. Link to comment Share on other sites More sharing options...

MusicalMommy Posted April 16, 2012 Author Share Posted April 16, 2012 Thanks. I would have never been able to find that info. That does look much more like what I have than any of the photos of the stingray teeth I saw. Feeling much more conficent in this identification. Thanks again.

Auspex Posted April 17, 2012 Share Posted April 17, 2012 Odd too the way the root is completely gone... It was a landscape river rock find; probably been tumbled and sorted with a lot more violence than nature alone could muster.

MusicalMommy Posted April 17, 2012 Author Share Posted April 17, 2012 http://www.oceansofkansas.com/Ptychodus2.html After visiting the above link I am pretty sure hands down this is what we found. Because of this discovery... my kids spent the afternoon hunting though the landscape rock dragging every rock they picked up into the house thinking it is a rare fossil. My oldest who is 6 even make little lable cards for them all and set up her own museum. I think she is hooked. Link to comment Share on other sites More sharing options...

siteseer Posted April 18, 2012 Share Posted April 18, 2012 Ptychodus teeth from the English Chalk can have really nice crowns but poorly-preserved roots. It is interesting to get a look at the inside and underside of a Ptychodus crown. I don't think I've seen that in any book or technical article. Odd too the way the root is completely gone...
