GW or Meg? And an earbone - Peace River, Florida


Meganeura

Recommended Posts

Okay so today I found a tooth that I’m not sure if it’s a Meg or a GW, and then an earbone (I know it’s an ear bone this time! :heartylaugh:) that I’m not sure what it’s from.

 

So starting with the shark tooth - the shape and size fits a GW, and the root, while slightly broken, also matches GW. However, it’s got a slight bourlette, which makes me think Meg. But I know that some GW’s have Bourlettes too. @Al Dente Any ideas?

Now for the earbone. I know it’s mammal and not cetacean… but that’s it. It is 27mm x 14.5mm:

My favorite things about fossil hunting: getting out of my own head, getting into nature and, if I’m lucky, finding some cool souvenirs.

GW for me, but low confidence

GW was my first thought as well - this was what it looked like fresh out of the water:

which is veryyyyyy GW to me. It’ll be my first if so! Which I’m very happy with - it’s quite the pretty tooth.

I think it is a great white but the bourlette is a little odd. 

Thank you! Looks like it peeled a little or something, lol.

Here’s a nice example of a great white with a thin bourlette. Photo from here-https://wset.com/news/local/local-couple-finds-fossilized-great-white-sharks-tooth-in-outer-banks

I think that settles it in my opinion for sure then - small bourlette but still GW. Thank you very much!

GW tend to have much more coarse serrations on the tooth than megs and this is well displayed by the tooth in question. I too am on the side of it being a GW.

 

 

Cheers.

I was showing pictures to my parents and they both actually commented on the serrations - which they've never done with a Meg, so that checks out too. Thanks Ken!

I agree, great white.  Blow up the picture and look closely at the serrations.  If serrations are in good shape, they are a good way to tell a meg from a GW.  Meg serrations are uniform and close together.  GW serrations are not as uniform, have noticeably different widths, and more spacing between individual serrations.  If serrations are pristine (usually not on water worn teeth) the very serration tips of megs (more rounded) and GWs (more pointed) have a different shape.  See the below picture,

Oh this was actually super helpful! The serrations are surprisingly still pointy, and definitely not uniform, they’re quite varied in spacing!
