An accurate size reference would be a huge help. The tape measure in the background makes it look huge I have a feeling it's much smaller than it appears and my guess would be cow shark tooth.

 

[azbmwcrew]

the width of the jaw bone is 1.5"

 

[GatorBoy]

I don't think it's a jawbone it appears to be a root of a single cow



shark tooth here is an example

 

[azbmwcrew]

Yeah, I really wouldn't know as I don't have any knowledge in this field

 

[GatorBoy]

I'm not 100 percent positive but that's what I would ID it as.
A very good size one in a piece of matrix as well that is a nice fossil.

 

[azbmwcrew]

do you think it is pretty old?

 

[GatorBoy]

Millions of years

 

[azbmwcrew]

oh nice. I wasn't sure if it was 10's of thousands or if it was prehistoric

 

[GatorBoy]

That fossil is likely the seven Gill cow shark roughly 2.5 -5 million years old.

 

[azbmwcrew]

Wow! That would be really amazing. What do you think of this one I also have in my collection?

African mosasaur tooth

 

[Harry Pristis]

The shark tooth is a phosphate matrix piece (like the mosasaur tooth) from Morocco. The shark tooth appears to be Otodus with a broken blade. The mosasaur is Late Cretaceous in age, while the broken shark tooth is from the Paleocene-Eocene. Otodus is believed to be ancestral to Carcharocles megalodon.

Cretaceous 60-120 million years ago(if I recall). Pretty old...

These mosasaurs are Latest Cretaceous, Maastrichtian age, 72.1 Ma to almost 66 Ma.
The Otodus teeth are Late Paleocene to Early Eocene, Thanetian to Ypresian age, roughly 59 Ma to 50 Ma. ("Ma." is Mega-anna, a million years before present.)

Great job.

Any idea on what the value would be on something like this?

Not a whole ton. Countries like morocco export these like sand.

Any idea on what the value would be on something like this?

The broken Otodus tooth, like any damaged shark tooth, has a collector value of zero.

The mosasaur tooth has some limited value -- check eBay to see what they are bringing.

Can you tell what this is?
