interesting cretaceous oddity

[Jared C]

It seems that every time I post in the fossil ID lately, it's something my friends found when they were with me - brand new eyes are really good at avoiding the "routine" we get into when hunting, and they produce all sorts of crazy cool finds as a result. Here are some field photos of something I suspect is fish scales - I can ask her for better photos if needed.

Here's a side angle I took so that the ridge is more evident:

Looks an awful lot like shark cartilage. Cool find! Here's a modern example, though the prisms may be a bit smaller:

That’s it: shark cartilage. See piece from the Ozan Fm. in the North Sulpher River.

Yup. That's where my thoughts went as well. Though I've never found any preserved cartilage, I have learned about it here on the forum so I'll recognize it when (and if) I ever see some.

 

Very cool!

 

 

Cheers.

I wouldn't restrict it to only sharks: sawskates and (I'm pretty sure) rays and chimaeroids also have prismatic cartilage. Excellent find!
