Jared C Posted March 21, 2022 Share Posted March 21, 2022 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.

ThePhysicist Posted March 21, 2022 Share Posted March 21, 2022 Looks an awful lot like shark cartilage. Cool find! Here's a modern example, though the prisms may be a bit smaller: 3 4 Forever a student of Nature Link to comment Share on other sites More sharing options...
DPS Ammonite Posted March 21, 2022 Share Posted March 21, 2022 That’s it: shark cartilage. See piece from the Ozan Fm. in the North Sulpher River. 7 My goal is to leave no stone or fossil unturned.

digit Posted March 21, 2022 Share Posted March 21, 2022 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!

Carl Posted March 21, 2022 Share Posted March 21, 2022 I wouldn't restrict it to only sharks: sawskates and (I'm pretty sure) rays and chimaeroids also have prismatic cartilage. Excellent find! 4 Link to comment Share on other sites More sharing options...
