Size?
And do you know what caused the lines in the fossil?
Nicely done.

Yes - I will get all the scientific information on the card that came with it tonight when I get home for the curious. Size wise, edge to edge, it is between a quarter and a nickel.It is a sharks tooth.
21 frame stack into Zerene and then ACR and PS.
And in a couple of days I can do the other side (I did the wrong side by accident, the other side shows the serrated edges better.)

the scratch marks? Likely sloppy handling from me. It got dropped numerous times before I got the clay to hold it from the back. It might polish out (I wouldn't think I could scratch the fossil itself that easily)... Size edge to edge is slightly less than a quarter. Image was full frame (Canon 6D) with no cropping using MP-E 65mm at 1x mag.Size? And do you know what caused the lines in the fossil?

What you have here is a Snaggletooth Shark (Hemipristis curvatus) tooth. It is an upper lateral. The osteodentine (root) is gone probably worn away as this can be softer than the rest of the fossil. The scratches are most likely feeding marks. A wonderful shot for sure. Love the lighting. Well done.

Holy Cow Doc! I will be curious to see if that matches what the "paperwork" says. I would have guessed tiger shark, but that certainly doesn't come from any type of knowledge.What you have here is a Snaggletooth Shark (Hemipristis curvatus) tooth. It is an upper lateral.

Sorry Piet. I just took a cursory look at it and now see the greater crook in the medial margin. This is, as you suggested, Galeocerdo (Tiger Shark). Sorry for not looking at it more closely and giving misinformation. I have been studying and collecting fossil shark teeth for the last 20 years. That was a dumb mistake. -DocHoly Cow Doc!

Hey Doc, my tiger shark guess was just that based on a quick Google image search. The Snaggletooth images that I saw were WAY Cool. I am going to have to find one of them.
Don't be rough on yourself. I bet you have a very cool collection!
