that is definetly a shark tooth, probaly a Meg but im not that good at identifing shark teeth

that belongs to No one, sorry just a rock

looks like chert but also a rock

chalcedony and a watered version of quartz, cool find!

*Mistake

not a tooth, teeth are very well preserved and u can clearly see the root and blade of the teeth, and u cant see it on that one which means its just a rock. Trust me i made the same mistanke, i picked up a flint nodule thinking it was a tooth Lol.

Just a rock but the rock itself looks like a eye of a trex

the 2nd pic is probaly a pic of a piece of crinoid in Cryptocrystalline Quartz in some vein

that really looks like pumice ( A vulcano rock )

definetly not a Meg and its just a rock, im sorry about that
