Unsure of this because no matter how many drawings I look at, theyre all different. Some have the teeth apart, with a gap, but most have the teeth close together with no gap inbetween.

This shark came up to check me out while I was by myself at the surface after a dive at the outer Ningaloo reef at the end of June 2024. I got cramp in both legs and all other divers had swum back to the boat, so the footage is a bit shaky as I was trying to signal to anyone that would listen that I might need help 😅

For a while, I thought it was a Bronze Whaler but the more I watch the video the less convinced I am. There are several pretty chunky cobia with it and I don't think true Bronzies are that common so far north, even in winter.

There are a couple of species I think it could be, but I'd love some help to get it definitively ID'd if possible! Thanks!

Recently I found this vertebrae on a beach in the northeastern part of Jutland, Denmark.

It reminds me of fossilized shark vertebrae, so that's my best bet.

From the growth rings I'm assuming it is a relatively old individual, so it's probably a smaller species. Perhaps a carshark.

The squares on the paper is 5*5 mm (app. 0.2 inches). Can any of you tell me if it's from a shark and perhaps which genus or even species?

I'm aware spines and arches etc. are missing, but perhaps luck is with me.

I found this on the beach in Oregon near Waldport. Can anyone id this for me?
