Big sand tiger


WhodamanHD

Recommended Posts

Went to brownies today, miocene, and I’ll have the haul until here later this week but I would like to know what species this sand tiger is. It’s purty big for a sand tiger, like an inch and a half. It’s got two cusps on either side, they seem to curve inward. I saved up for Kent’s book on fossil identification so I’ll have that by the 28th.

Can't help on the ID, but that's a nice looking tooth, as well as being of a very decent size! :meg::dinothumb:

Wish I was in an area you don't have to dig 3 feet through sandstone to get to the goodies.

Thanks! When I saw it rolling in the surf I just about fell on it!

Thanks! I’ll be doing the same sort of thing soon, I’m gonna start heading to the Carboniferous of MD soon hopefully. Not as easy but rewarding if your lucky!

Nice tooth!

Congratulations on the wonderful find.

 

Sorry, but I am no good with separating the sand tiger teeth.

Very pretty,  Great root , excellent colors, multiple cusps.... Length? I had a Sand Tiger up about a month ago and was asking your question... How to differentiate between Sand Tiger lookalikes... I will be waiting for any clues...:popcorn:

Thanks! I hope we can get some definitive answers. My mind seems to get hooked o. To a different pattern every time I go hunting, this time it was sand tigers.

Oh my God that sand tiger is pristine! Really nice! :meg:

 

As far as species to species ID, I'm still learning.

Can you get us a side view of the tooth without your hand in the way. Brownies Beach is ?Miocene, correct.

Sure, I’ll try tomorrow. Yes, early to mid miocene.

Yeah, I’m surprised it made it this well myself.

Thanks. This tooth reminds of a sand tiger found in the Pungo River Formation at Lee Creek. It is labeled as Carcharias sp. on Elasmo.com

Hi Don,

 

Elasmo was tentative on ID's and rightly so given the differing opinions it reported from researchers especially for Miocene teeth.  If you follow Kent and his Chesapeake sharks book I think you go with Carcharias cuspidata.  That would also be how the average collector 30 years ago would have identified it, I think.  Luckily, it's a large tooth with an apparetnly smooth, broad-based crown which separates it from Carcharias acutissima (generally smaller with at least a weakly-striated, narrower-based crown. 

 

When experts look at modern dentitions of any shark species, they see at least pretty good variation in tooth shape per jaw position, so they wonder how fossil teeth can be confidently named to species in many cases especially for something like this tooth with which you have maybe three species to choose from, each having its incompletely-understood range of variation which some say overlap.  I don't think anyone would say this tooth is C. accutissima but they might go with Carcharias sp. as you suggested and that might be the name to go with today..
