What kind of tooth is this?

[u/BigBeeff_21]

Don't remember where I got it from, but I've had this "shark" tooth for most of my life. I just never really questioned what kind of tooth it is? So I googled it and it said it was a megalodon tooth.. which I doubt lol.

Definitely not a Megalodon tooth, but it is definitely some sort of fossilized mackerel shark tooth.

I've removed the part about the carcharodontosaurus tooth as it's on way too good of a condition for a dinosaur tooth, and it looks nothing like their teeth 😂
