@drsukhendu-mukhopadhyay This is a lovely tooth from a shark of the genus Carcharhinus! As it seems to have been washed in from offshore and is a long-lived genus, it is hard to say how old the tooth is

@the-rogue do you have more specific location information? Nice tooth!

@mason-hintermeister unfortunately no, all I know is that It came from a small site in the formation

Well, knowing the creature’s age would help in my opinion, even though the equipment needed is expensive. To me, it looks like a broken off part of a big tooth, but I’m not sure about which kind of tooth it is.

@aggelos-mantos-3 I’m not sure what you mean by it being part of a larger tooth, it seems to be a whole shed tooth

I mean if memory serves, Hell creek only has 3 toothy theropod groups: Tyrannosaurs, Dromeosaurs, and troodontids. I don’t see the prominent serrations on the distal side I would expect out of a Troodontid, so its probably either Tyrannosaurus or Acheroraptor. Use this description to help compare to Acheroraptor…[Read more]

@mason-hintermeister the tooth doesn’t seem to match up with archeroraptor very well with the images I’ve seen, leading me to believe its a tyrannosaur. in the research I’ve done though I’ve discovered two teeth that I own are likely archeroraptor

This is called coquina, its crushed fossil shells compressed together. Because of it’s unique properties due to its composition, forts were built out of it which were said to “eat” cannonballs, as they simply sunk in rather than shattering the structures.

Very interesting thank you!
